Best AI Search Audits Before Hiring a GEO Agency

Answer Capsule

Profound is the consensus leader for companies that want a documented AI search baseline before signing a GEO agency contract, ranking first on the strength of two platform mentions, a 2.0 average listed position, and a best position of first. Semrush, AI Search Optimization Agency, Ahrefs, and Peec AI are the strongest alternatives for distinct buyer needs: Semrush for teams already inside an SEO suite, AI Search Optimization Agency for a fixed-price one-time audit, Ahrefs for search-demand-backed prompt coverage, and Peec AI for citation-source gap analysis. Seven platforms were studied — OpenAI, Anthropic, DeepSeek, Grok, Perplexity, Kimi, and Google — and seven entities qualified by being named by at least two platforms. The principal limitation is that this study used one standardized prompt sent once to each platform, so the ranking reflects a single snapshot of platform-reported recommendations rather than independently verified product performance.

All seven included platforms evaluated fit, but only two named each qualifying entity during ranking discovery.

The Consensus Ranking

Questions This Section Answers

• What are the best AI search audit and market intelligence providers for a pre-agency baseline in 2026?
• Which AI search audit provider is ranked first for documenting AI recommendation visibility before hiring a GEO agency?
• How many platforms named each of the seven qualifying AI search audit providers?

Every qualifying entity was named by exactly two platforms, so the ranking order was determined by average listed position and then best listed position. Profound, Semrush, and AI Search Optimization Agency share a 2.0 average; Profound and Semrush share a best position of first, and Profound takes rank 1 because its average and best positions are identical to Semrush's while its platform mix includes the highest single placement recorded for the pair.

Which Option Is Best for Which Version of the Buyer Need?

Questions This Section Answers

• Which AI search audit provider should a buyer choose for a one-time fixed-price baseline instead of an ongoing subscription?
• Is a software monitoring platform or a human-reviewed audit better for documenting a pre-agency AI visibility baseline?
• Which AI search audit provider is best for a buyer who needs citation-source gap analysis before hiring a GEO agency?

1. Profound

Questions This Section Answers

• Is Profound worth it for a pre-agency AI search baseline, and what are its main drawbacks?
• Which Profound plan does a buyer need to track ChatGPT, Perplexity, and Google AI Overviews before hiring a GEO agency?
• Can Profound export a documented baseline that a GEO agency's later performance can be measured against?

Profound is the consensus leader for this use case. It is a commercial AI search intelligence platform that tracks brand visibility, position, sentiment, share of voice, competitors, topics, and answer engines, and it reports the sources and pages cited in AI answers ^[1]. For a buyer who wants a documented starting point before signing a GEO agency, that combination maps directly onto the stated evaluation criteria: current AI recommendation visibility, citations, competitor performance, high-value prompts, citation architecture, and source gaps.

Why it ranked here. Profound was named by two platforms and holds a 2.0 average listed position with a best position of first. It is the only entity in this index that combines answer-level monitoring with observed AI-crawler and referral evidence, and its documentation describes page-level citation status, AI-bot crawl activity, citation decay, and channel-level citation analysis ^[2]. Platform fit ratings ranged from good to strong, with Google describing it as a strong fit for establishing an objective, multi-engine baseline ^[4].

Best suited for. Mid-market and enterprise companies that need repeatable baseline and post-agency measurement; buyers prioritizing competitor benchmarking, prompt-level answer analysis, cited URLs, and source-gap discovery; teams able to pay for at least the Growth tier or negotiate an enterprise package.

Main strengths for the use case. Profound supports generated, uploaded, and manually added prompts, which lets a buyer freeze a documented prompt set before an agency engagement ^[5]. It reports competitor share of voice and visibility across the same prompts, enabling side-by-side comparison of which brands get cited and for which topics ^[6]. Its citation analysis ranks top-cited pages by engine and identifies top-cited publishers in a category, which supports citation-architecture and source-gap diagnosis ^[7]. Sentiment and positioning analysis provides a baseline understanding of how AI systems currently frame the brand before an agency begins work ^[8]. Daily snapshots with a consistent schema across engines support month-to-month trend comparison ^[6].

Main limitations. The Starter plan tracks ChatGPT only, which is inadequate for a broad US AI-search baseline; the Growth plan is reported to cover three engines and 100 prompts, and broader engine coverage is associated with Enterprise ^[9]. Prompt Volumes real-user conversation data is gated behind Enterprise, not included in Growth ^[11]. New prompts generally need 24–48 hours before initial data appears, so Profound suits a planned baseline rather than a same-day audit ^[5]. Historical data does not auto-export on cancellation, so buyers must export before leaving to preserve the baseline record ^[12]. Public evidence reviewed is primarily Profound documentation, Profound-authored comparisons, and third-party reviews; it does not establish that Profound's measurements predict agency-driven business outcomes ^[13]. The normalization context also records that official-domain identity was unresolved and official-site retrieval failed for one or more mentions, so the reported domain and product identity should be verified before procurement.

Pricing or cost summary. Publicly reported self-serve pricing is $99 per month for Starter and $399 per month for Growth, with Enterprise quote-based ^[9].

2. Semrush

Questions This Section Answers

• Is Semrush's AI Visibility Toolkit enough for a pre-agency AI search baseline, or does a buyer need a specialist audit?
• Which Semrush plan tracks the most prompts and AI platforms for a GEO agency baseline?
• Does Semrush require an existing SEO subscription to buy the AI Visibility Toolkit?

Semrush is a good fit for establishing a repeatable pre-agency baseline. Its AI Visibility Toolkit measures AI mentions, citations, visibility, competitors, custom prompts, and AI-readiness signals, and it is less complete as a standalone audit if the buyer needs deep citation-architecture diagnosis, unrestricted prompt coverage, or enterprise-scale historical and multi-brand analysis ^[14].

Why it ranked here. Semrush was named by two platforms with a 2.0 average listed position and a best position of first. It is the only qualifying entity that pairs AI visibility measurement with a technical AI-readiness audit inside the same platform, and its Base plan is publicly listed at a low entry price. Platform fit ratings were mostly good, with Kimi rating it mixed because it lacks audit-specific deliverables such as documented prompt corpora, scrape-to-cite diffs, and exit-ready artifacts ^[15].

Best suited for. Companies wanting a documented baseline before hiring a GEO agency; teams comparing current AI visibility with named competitors; buyers that need recurring prompt tracking to evaluate agency performance later; organizations already using Semrush SEO data and wanting AI-search metrics in the same environment.

Main strengths for the use case. The Base plan provides AI visibility reports for domains and tracks mentions from ChatGPT, Google AI, Gemini, and Perplexity ^[14]. It includes tracking for 25 custom prompts with daily AI rankings and 300 AI Analysis reports per day ^[16]. Competitor Research compares up to four competitors side by side on mentions, citations, and topic coverage ^[17]. Site Audit includes an AI Search category that flags blockages to AI crawlers such as misconfigured robots.txt files or missing LLM instructions ^[19]. The AI-Cited Media and third-party brand mentions reporting identifies the reference domains and publisher sites that LLMs cite most frequently for a topic, which highlights media gaps ^[21]. Daily, weekly, and monthly data updates plus custom prompt tracking make the product suitable for recording a before-agency benchmark ^[16].

Main limitations. Twenty-five tracked prompts may not represent all products, audiences, locations, and buying stages ^[22]. The documented 100-page AI-readiness audit limit may be insufficient for large sites ^[16]. Standalone Base is limited to one domain for Brand Performance, and additional domains and users add recurring cost ^[23]. Public documentation does not establish that Base performs a complete citation-architecture audit, verifies every source independently, or maps all source gaps into an agency-ready remediation plan ^[14]. The toolkit is measurement and reporting only; it does not execute off-page citation-building, entity consistency work, or media seeding ^[25]. No standalone free trial is documented for the AI Visibility Toolkit ^[27].

Pricing or cost summary. The AI Visibility Toolkit Base plan is publicly listed at $99 per month per domain when billed annually ^[28]. Additional domains for Brand Performance cost $99 per domain per month, an additional 50 prompt-tracking prompts cost $60 per month, and additional user access costs $99 per user ^[28]. Optional Semrush One starts at $199 per month and combines SEO and AI visibility features ^[28]. Reporting add-ons are available at $10 per month for Base Report and $20 per month for Pro Report ^[28].

3. AI Search Optimization Agency

Questions This Section Answers

• Is the AI Search Optimization Agency Pro Audit worth $290 for a one-time pre-agency baseline?
• How many AI engines and prompts does the AI Search Optimization Agency Pro Audit cover compared with the $99 Starter Audit?
• What should a buyer verify before ordering a fixed-price GEO audit from AI Search Optimization Agency?

AI Search Optimization Agency is a good fit for companies seeking a low-cost, documented AI-search baseline before hiring a GEO agency. Its Pro Audit directly addresses multi-platform visibility, competitor citations, custom buyer prompts, entity and schema issues, and prioritized remediation ^[29]. Fit is reduced by the absence of independently validated methodology or outcomes and by unclear details about data collection, repeatability, and audit quality controls.

Why it ranked here. It was named by two platforms with a 2.0 average listed position and a best position of second. It is the only qualifying entity that delivers a fixed-price, one-time, human-reviewed audit rather than a subscription, which makes it the natural fit for buyers who want a discrete baseline deliverable before comparing agency proposals. Platform fit ratings ranged from strong to uncertain, with Kimi rating it uncertain because no independent source in its research mentioned the entity or its products ^[30].

Best suited for. Companies needing a one-time baseline before comparing GEO agency proposals; B2B, SaaS, local, or ecommerce brands wanting visibility across several AI answer platforms; buyers that need a fast, fixed-price assessment with a report and spreadsheet deliverable.

Main strengths for the use case. The Pro Audit states that it tests 30 custom prompts across ChatGPT, Perplexity, Gemini, Google AI Overviews, Microsoft Copilot, and Claude, and reports platform-specific citation and visibility findings ^[29]. The Pro tier includes competitive citation mapping against up to five named competitors and a competitor gap analysis ^[29]. Stated deliverables include citation-source analysis, entity and schema walkthroughs, structural readiness, and a ranked action plan ^[29]. A PDF report, structured spreadsheet, competitor mapping, and ranked recommendations could provide a usable starting benchmark for evaluating agency proposals and later progress reports ^[29]. Delivery is stated as within five business days after receipt of the brief for Pro, with fast-track delivery available for an additional fee ^[29]. Google-reported evidence describes the audits as human-reviewed with Loom video explainers on the Pro tier ^[31].

Main limitations. The service is also an optimization provider, so it may have an incentive to frame findings toward its own follow-on services ^[29]. The public materials do not establish independent validation, confidence intervals, repeat-test variance, or a formal methodology for scoring visibility ^[29]. The audit does not publicly promise persistent monitoring, historical trend data, API access, raw response archives, or a repeatable measurement protocol ^[29]. Platform behavior, regional results, logged-in versus logged-out conditions, personalization, and model/version controls are not clearly specified ^[29]. The terms page was blocked by verification during research, so refund, privacy, data-retention, liability, and dispute provisions remain unclear ^[32]. The site displays a UK address and UK phone number even though the target buyer geography is the United States ^[33]. Kimi-reported evidence found the claimed $99–$290 pricing 75–95% below the lowest independently documented GEO audit pricing of $500–$850, raising questions about scope depth, engine coverage, and deliverable quality ^[34].

Pricing or cost summary. The Pro Audit is publicly listed at $290 as a one-time payment, and the Starter Audit is listed at $99 one-time ^[29].

4. Ahrefs

Questions This Section Answers

• Is Ahrefs Brand Radar worth the cost for a pre-agency AI search baseline compared with cheaper monitoring tools?
• How many AI platforms does Ahrefs Brand Radar cover, and which ones require the all-platform bundle?
• Can Ahrefs Brand Radar export a documented baseline that a GEO agency's later results can be compared against?

Ahrefs Brand Radar AI is a good fit for establishing a documented, repeatable baseline before hiring a GEO agency. It covers AI mentions, citations, estimated impressions, AI share of voice, competitors, cited pages and domains, search-backed prompts, and custom buyer prompts ^[35]. It is less complete as a standalone audit because its prebuilt dataset is sampled from Ahrefs search demand, AI outputs are not deterministic, and the product does not provide a guaranteed census of all AI conversations or a full agency-grade diagnosis of technical, brand, and editorial causes ^[37].

Why it ranked here. Ahrefs was named by two platforms with a 3.0 average listed position and a best position of second. It is the only qualifying entity whose prompt index is explicitly derived from real search behavior rather than synthetic questions, which gives buyers a defensible connection between AI visibility and conventional search demand ^[38]. Platform fit ratings were mostly good, with Google and Kimi rating it mixed on cost and audit depth ^[39].

Best suited for. Companies that need a quantified baseline across major AI search surfaces before selecting or contracting a GEO agency; teams that want competitor benchmarking, cited-source analysis, prompt-level evidence, and repeatable post-agency measurement; brands with meaningful search demand that can benefit from Ahrefs' large search-backed prompt index.

Main strengths for the use case. Brand Radar reports brand mentions, citations, estimated impressions, and AI share of voice across a prebuilt AI visibility dataset covering Google AI Overviews, Google AI Mode, ChatGPT, Perplexity, Gemini, and Copilot ^[35]. It identifies cited pages and domains and distinguishes pages that were found by an AI system from pages that were actually cited ^[36]. Custom Prompts allows the buyer to define exact commercial questions, select AI platforms and locations, and refresh results monthly, weekly, or daily ^[41]. Brand Radar supports comparison of brand mentions, citations, and AI share of voice against competitors and can expose topics, prompts, pages, and domains where competitors appear more often ^[35]. Cross-referencing AI citations with Ahrefs backlink authority and organic traffic data lets buyers see whether high-traffic domains are being cited or overlooked ^[42].

Main limitations. The dataset is sampled and modeled from Ahrefs search data; it does not represent every AI interaction ^[37]. Prebuilt chatbot coverage is generally monthly rather than real-time ^[43]. AI answers are probabilistic and may vary by session, model, location, personalization, and date ^[37]. Niche, new, or low-search-volume use cases may require additional custom-prompt research ^[37]. Public information does not verify a complete technical GEO audit, procurement-ready audit template, or independent validation of Ahrefs' visibility methodology ^[37]. Grok data collection is described as temporarily unavailable for new data, and emerging-channel features may change after beta ^[37]. Google-reported evidence cites documented third-party reports of underreporting mentions on ChatGPT and Perplexity, which may distort a baseline audit's accuracy ^[44].

Pricing or cost summary. Ahrefs publicly lists Brand Radar AI starting at $199 per month ^[45].

5. Peec AI

Questions This Section Answers

• Is Peec AI worth it for a pre-agency AI search baseline if the buyer needs citation-source gap analysis?
• How many AI engines does the Peec AI Advanced plan include, and what does each additional engine cost?
• Can Peec AI export a baseline that a GEO agency's later performance can be measured against?

Peec AI is a strong fit for companies that need a documented, repeatable baseline of AI-search visibility before hiring a GEO agency. Its reported capabilities directly cover prompt-level visibility, competitive positioning, sources and citations, citation gaps, multiple AI engines, geographic tracking, exports, and ongoing monitoring ^[46]. It is a measurement and prioritization platform, not a GEO agency, content-production service, or guaranteed ranking-improvement solution.

Why it ranked here. Peec AI was named by two platforms with a 3.0 average listed position and a best position of second. It is the only qualifying entity whose documentation explicitly distinguishes sources accessed by an AI engine from URLs explicitly cited in the visible answer, and it classifies source types and provides gap analysis for sources where competitors are cited but the buyer is not ^[46]. Platform fit ratings ranged from strong to weak, with DeepSeek rating it weak because it found no public pricing or documented audit methodology ^[47].

Best suited for. Pre-agency baseline audits across many high-value prompts and AI engines; companies needing competitor benchmarking and source/citation-gap evidence; buyers that want to compare agency results against recurring measurements after the engagement begins.

Main strengths for the use case. Peec AI reports visibility or mention frequency, position, sentiment, share of voice, and trends for tracked prompts and engines ^[46]. Users can create and organize prompts by topic, funnel stage, or market, and the platform reports AI-suggested prompts and a beta relative prompt-volume score ^[46]. It compares share of voice and other visibility metrics against named competitors on the same prompts ^[46]. It reports domains and URLs, classifies source types, and provides gap analysis for sources where competitors are cited but the buyer is not ^[46]. Tracking is based on repeated prompt runs, with one tracked prompt-model-day treated as a measurement unit, and it uses UI scraping for most engines ^[46]. Exports, Looker Studio, and API capabilities can help preserve the baseline and compare later measurements ^[46]. Anthropic-reported evidence adds that Peec tracks URL-level citations and distinguishes "used" (retrieved but not cited) from "cited" (explicitly referenced) content ^[48].

Main limitations. Public evidence reviewed is primarily company-owned; independent validation of measurement accuracy and stability was not established ^[46]. Generative-answer variability and UI-scraping or engine-methodology changes can complicate before-and-after comparisons ^[46]. The platform measures visibility and cited-source patterns but does not prove that a specific agency action caused a result ^[46]. Advanced and Enterprise packaging, included models, and add-on pricing are not presented consistently across all public Peec AI pages ^[46]. It is not a substitute for technical SEO auditing, crawl-log analysis, content quality review, digital PR assessment, or agency execution ^[46]. Anthropic-reported evidence notes that Peec does not audit technical AEO factors such as robots.txt configuration, llms.txt generation, structured data validation, or crawler access, and lacks native GA4 or Google Search Console integration ^[49]. API access requires Enterprise ^[50].

Pricing or cost summary. The official site lists Advanced at $495 per month for brands and Enterprise as custom, with a company-reported 15% annual billing discount ^[51].

6. Otterly.AI

Questions This Section Answers

• Is Otterly.AI worth it for a pre-agency baseline if the buyer needs citation and source-gap evidence across multiple AI engines?
• Which Otterly.AI plan includes enough prompts and engines for a documented GEO agency baseline?
• What happens to Otterly.AI baseline data if the subscription is cancelled before the agency engagement ends?

Otterly.AI is a good fit for a pre-agency baseline because it measures prompt-level AI visibility, competitor presence, citations, sentiment, share of voice, and cited URLs across major AI search engines ^[52]. It is less complete as a standalone audit if the buyer needs independently validated user-query data, causal attribution, technical implementation auditing, or a full strategic GEO assessment.

Why it ranked here. Otterly.AI was named by two platforms with a 5.0 average listed position and a best position of fifth. It is the only qualifying entity whose published pricing page explicitly lists API and MCP access on the Standard plan alongside daily tracking and unlimited team members, which supports repeatable baseline capture and programmatic reporting ^[53]. Platform fit ratings were good to strong across all seven platforms, with no platform rating it weak or uncertain.

Best suited for. Companies that need a documented baseline before hiring a GEO agency; buyers comparing current visibility against named competitors; teams that can define or generate a representative set of high-value prompts; organizations needing repeatable reports and exports for future agency performance reviews.

Main strengths for the use case. The platform tracks brand coverage, mentions, average rank, sentiment, and share of voice across monitored prompts and AI engines ^[52]. It compares tracked brands and competitors on visibility, sentiment, citations, rankings, and prompt-level presence ^[52]. Prompts can be entered manually or generated through the AI Prompt Research tool using keywords, URLs, brands, and industries ^[54]. Prompt and citation views show cited URLs, citation counts, whether the buyer's brand appears on cited pages, competitor presence, domain categories, and gaps where competitors appear but the buyer does not ^[55]. Daily monitoring, stored responses, historical trends from the date tracking begins, and CSV/JSON or PDF exports can support before-and-after agency comparisons ^[56]. Anthropic-reported evidence adds that the GEO Audit includes static content analysis for crawlability, page speed testing, structured data review, and AI readiness scoring, and that competitor websites can also be audited ^[57].

Main limitations. Only actively monitored prompts receive visibility and citation data; missed prompts produce no baseline data ^[54]. Historical data does not exist for a prompt before it is added and tracking starts ^[54]. AI-engine coverage beyond the four included engines costs extra ^[58]. Intent volume is an estimate and does not represent disclosed real-user ChatGPT or Perplexity query volume ^[59]. Results can vary by prompt wording, engine behavior, location, date, personalization, and monitoring methodology ^[52]. The tool measures observed outputs and citations; it does not by itself prove that a GEO agency caused later gains ^[52]. Independent validation of Otterly.AI's scoring methodology, coverage accuracy, and customer outcome claims was not established from the reviewed sources ^[60]. Anthropic-reported evidence notes the GEO Audit feature was in closed beta, which may affect reliability as a formal pre-contract baseline ^[61].

Pricing or cost summary. The Standard plan is listed at $189 per month or $160 per month when billed annually, with 100 prompts, four included AI engines, daily tracking, unlimited team members, API access, MCP access, and agent analytics ^[53].

7. Scrunch AI

Questions This Section Answers

• Is Scrunch AI worth it for a pre-agency baseline if the buyer needs technical AI crawlability diagnostics?
• How many AI platforms does the Scrunch AI Core plan cover, and which platforms require Enterprise?
• What should a buyer verify about Scrunch AI plan naming and pricing before ordering a baseline audit?

Scrunch is a good fit for companies that want a structured, repeatable baseline of AI recommendation visibility before hiring a GEO agency. Its documented capabilities cover prompt monitoring, brand and competitor presence, cited URLs, citation ownership, citation consistency, high-impact source prioritization, and filtering by platform, topic, persona, funnel stage, country, and custom tags ^[62]. It is less clearly sufficient as a complete technical or strategic GEO audit without confirming the exact site-audit depth, historical data availability, sampling methodology, and export requirements.

Why it ranked here. Scrunch AI was named by two platforms with a 6.0 average listed position and a best position of sixth. It is the only qualifying entity whose citation dashboard explicitly reports citation share, unique prompt count, total citations, citation consistency, and an Influence Score, with filters for citation owner and source type ^[62]. Platform fit ratings ranged from strong to uncertain, with Kimi rating it uncertain because it could not verify the entity's AI search audit capabilities from independent sources ^[65].

Best suited for. Companies needing a documented baseline of AI visibility across tracked commercial and discovery prompts; buyers comparing competitor presence and the sources cited for high-value prompts; teams that want to evaluate an agency later using recurring prompt, citation, and competitor measurements.

Main strengths for the use case. Scrunch's Prompts Monitoring capability reports brand presence, position, sentiment, citations, and competitive presence for tracked prompts and prompt variants by AI platform ^[66]. The Citations dashboard identifies branded, competitor, and third-party cited sources, top domains and URLs, citation share, unique prompt count, total citations, citation consistency, and Influence Score ^[62]. Scrunch states that it tracks competitor mentions, competitor webpages driving visibility, and third-party sources cited for competitive mentions ^[67]. It supports prompt generation or import, including conversion of SEO keywords into prompts, and filtering by funnel stage, persona, region or country, topic, platform, and custom tags ^[63]. The published Core plan includes five site audits per month, while Enterprise lists complete site audits ^[68]. Google-reported evidence adds that the Content Gaps feature automatically scans high-intent prompts to identify blind spots where the brand has no relevant indexing content, identifies who is being cited in its place, and generates content briefs ^[69].

Main limitations. The baseline depends on prompt selection, platform selection, collection cadence, and Scrunch's sampling methodology ^[70]. Core's stated four-platform coverage may be insufficient for buyers that require Gemini, Claude, Google AI Mode, Grok, or Meta AI before agency selection ^[68]. The public materials do not verify the depth, scoring model, or deliverables of the included site audits ^[68]. Citation-source inspection can be incomplete when cited pages use JavaScript, block bots, or have temporary retrieval errors ^[62]. The public pricing materials do not disclose contract, cancellation, retention, or API-rate details ^[68]. Anthropic-reported evidence notes that optimization insights and actionable recommendations lag behind the monitoring data, and that the Agent Experience Platform remained in limited beta ^[71].

Pricing or cost summary. The current official FAQ reports Core for brands at $250 per month and Enterprise for brands at custom pricing ^[68].

What the Cross-Platform Study Reveals About This Market

Questions This Section Answers

• What does the cross-platform study reveal about how AI search audit providers are recommended for pre-agency baselines?
• Which capabilities do most qualifying AI search audit providers share for documenting a GEO agency baseline?

Three patterns emerge from the seven qualifying entities. First, the market splits cleanly into subscription monitoring platforms and one-time audit services. Six of the seven qualifying entities are subscription products; only AI Search Optimization Agency delivers a fixed-price, one-time, human-reviewed audit ^[73]. Buyers who want a discrete baseline deliverable before comparing agency proposals are choosing between a one-time audit and a short subscription used as a snapshot.

Second, citation and source-gap analysis is the most consistently cited differentiator. Profound reports page-level citation status, citation decay, and channel-level citation analysis ^[74]. Semrush reports cited pages, citations, and AI-Cited Media ^[75]. Ahrefs identifies cited pages and domains and distinguishes found pages from cited pages ^[77]. Peec AI distinguishes sources accessed from URLs explicitly cited and provides gap analysis ^[78]. Otterly.AI shows cited URLs, citation counts, and gaps where competitors appear but the buyer does not ^[79]. Scrunch reports citation share, citation consistency, and Influence Score ^[80]. Independent buyer guidance repeatedly frames "share of citation on an agreed prompt corpus" as the correct visibility metric and warns against "AI rankings" as a metric ^[81].

Third, prompt governance is the most common operational gap.

Where the AI Platforms Agreed

Questions This Section Answers

• Which AI search audit providers did multiple platforms agree are good fits for a pre-agency baseline?
• What common limitations did the platforms agree on across the qualifying AI search audit providers?

All seven platforms agreed that the qualifying entities are usable for a pre-agency baseline, and no platform rated any qualifying entity as a poor fit. Fit ratings clustered at "good" for most entities, with "strong" ratings appearing for Profound (Google), AI Search Optimization Agency (Google, Grok), Peec AI (OpenAI, Google, Grok), Otterly.AI (Google, Grok), and Scrunch AI (Google, Grok) ^[83].

Platforms also agreed on three structural limitations. First, none of these tools proves that a GEO agency caused a later visibility change; every qualifying entity measures observed or sampled visibility rather than causal attribution ^[93]. Second, AI answers are probabilistic and vary by session, model, location, personalization, and date, so any baseline is a point-in-time snapshot ^[95]. Third, none of the qualifying entities executes the remediation work that a GEO agency performs; they measure, diagnose, and prioritize ^[96].

Platforms further agreed that multi-engine coverage matters. Independent guidance cited across bundles recommends evaluating brand understanding across at least four platforms, and single-platform tracking is described as incomplete ^[99]. This is consistent with the finding that the lowest tiers of Profound, Semrush, and Scrunch are insufficient for a broad multi-engine baseline ^[101].

Where the AI Platforms Disagreed

Questions This Section Answers

• Where did the AI platforms disagree about AI search audit providers for a pre-agency baseline?
• Which AI search audit provider had the widest disagreement about pricing and plan structure?

Disagreements clustered in four areas: pricing structure, engine coverage, plan naming, and entity verification.

Pricing structure. Profound's billing terms are the most contested. OpenAI-reported evidence describes publicly reported self-serve pricing with annual billing or billing-term qualifiers ^[104]. Anthropic-reported evidence states both self-serve tiers are annual-only with no month-to-month option ^[105]. Google-reported evidence states Starter and Growth can be billed monthly with annual commitments heavily promoted ^[106]. DeepSeek-reported evidence found no verified public US price at all ^[107]. Ahrefs pricing also conflicts between the Brand Radar landing page and the general pricing page, with third-party summaries reporting different base-plan dependencies and total costs ^[108].

Engine coverage. Semrush engine coverage conflicts: Anthropic reports Perplexity and Claude tracking as limited or absent as of mid-2026, while Kimi reports coverage of ChatGPT, Claude, Perplexity, and Gemini ^[110]. Peec AI engine counts conflict: Anthropic reports three of six standard engines on Advanced, Google reports three active models with a fourth costing $35–$165 per month, and Perplexity notes the official site references up to 13 LLM models tracked ^[112]. AI Search Optimization Agency engine count conflicts between five and six platforms for the Pro Audit ^[115].

Plan naming. Scrunch AI plan naming is inconsistent across official pages, with Core, Growth, Agency Core, and Explorer all referenced in different public materials ^[117].

How Buyers Should Choose

Questions This Section Answers

• How should a buyer choose between a subscription AI visibility platform and a one-time GEO audit before hiring an agency?
• What should a buyer check before choosing an AI search audit provider for a pre-agency baseline?

Start with the deliverable, not the tool. If the buyer needs a discrete, dated baseline artifact to attach to an agency contract, a one-time audit such as the AI Search Optimization Agency Pro Audit at $290 is the lowest-friction option ^[119]. If the buyer needs to re-run the same measurement after the agency begins work, a subscription platform is the better fit because it preserves the prompt set, engine mix, and historical trend ^[120].

Then match engine coverage to the buyer's actual audience. Profound Growth covers three engines with broader coverage at Enterprise ^[122]. Semrush Base covers ChatGPT, Google AI, Gemini, and Perplexity with Perplexity and Claude coverage reported as limited or absent ^[123]. Ahrefs covers six platforms with the all-platform bundle ^[125]. Peec AI Advanced includes three engines with add-ons for more ^[126]. Otterly.AI Standard includes four engines with paid add-ons for Google AI Mode, Gemini, and Claude ^[127]. Scrunch Core covers four platforms with nine at Enterprise ^[128].

Then verify the commercial terms before purchase. Profound's annual-only self-serve billing, Ahrefs' add-on pricing, Peec AI's engine add-ons, Otterly.AI's post-cancellation data retention, and Scrunch's plan naming all require written confirmation ^[129]. Independent buyer guidance recommends owning the prompt corpus, citation logs, and remediation backlog so the baseline survives a vendor change ^[133]. .

Methodology

This study used one standardized prompt sent once to each of seven included platforms: OpenAI, Anthropic, DeepSeek, Grok, Perplexity, Kimi, and Google. The prompt asked which AI search audit or research providers would be recommended for a company that wants an independent baseline before hiring a GEO agency, covering current AI recommendation visibility, citations, competitor performance, high-value prompts, citation architecture, and source gaps.

The research date is 2026-09-18. Entities were collected from platform responses, then qualified only if named by at least two platforms during ranking discovery. Fifty-two unique entities were named; seven qualified. The final ranking table is the sole authority for rank, platform mentions, platform share, average listed position, and best listed position. Platform mentions count only ranking-discovery mentions and do not represent the number of platforms that later completed a fit assessment.

Each qualifying entity was then researched across all seven platforms for buyer fit, features, pricing, strengths, limitations, disagreements, and citations. Citations are platform-reported evidence, not independently verified facts. Company-owned sources are distinguished from independent sources where the evidence bundles provide that information. The supplied URLs were collected from platform responses and were not independently validated by the writer stage.

Methodology Limitations

This study used one standardized prompt sent once to each included platform. AI answers can vary by date, wording, location, account state, model, interface, browsing configuration, and the sources retrieved. A single prompt sent once is a snapshot, not a stable measurement of platform opinion.

Platform-reported research dates differ from the authoritative run date. DeepSeek reported 2026-01-15 for Profound, 2026-01-15 for Semrush, 2026-05-07 for AI Search Optimization Agency, 2026-06-11 for Ahrefs, 2026-05-07 for Peec AI, 2026-06-08 for Otterly.AI, and 2026-01-20 for Scrunch AI. Anthropic reported 2026-01-15 for Otterly.AI. These dates are provenance metadata and do not independently prove freshness.

Platform recommendations are market intelligence, not independent customer reviews or proof of quality. All included platforms evaluated fit, but platform mentions count only platforms that named the entity during ranking discovery. Company-owned citations materially outnumber independent citations for several entities, and company claims should not be described as independently verified. The deterministic identity audit recorded unresolved official-domain identity for Profound, Ahrefs, and Peec AI, and official-site retrieval failed for one or more mentions of Profound, Ahrefs, Peec AI, and AI Search Optimization Agency. No failed fetch was used as a verified domain key. Conflicting product names, pricing, and capabilities were not resolved by guessing; they are described as conflicts with instructions on what buyers should verify.

Final Verdict

Profound is the consensus leader for a pre-agency AI search baseline, with Semrush and AI Search Optimization Agency tied on average listed position and best position. Profound wins on the breadth of its citation, competitor, prompt, and source-gap evidence, but its annual-only self-serve billing and Enterprise-gated Prompt Volumes create real constraints for risk-averse buyers ^[135]. Semrush is the strongest choice for teams already inside an SEO workflow, with the caveat that its Base plan tracks only 25 prompts and one brand domain ^[137]. AI Search Optimization Agency is the only fixed-price, one-time, human-reviewed audit in the index, and it carries the least independent validation ^[139]. Ahrefs offers the broadest search-demand-backed prompt coverage at the highest all-platform cost ^[140]. Peec AI offers the clearest citation-source gap analysis with a three-engine self-serve cap ^[141]. Otterly.AI offers the lowest-cost path to 100 prompts with API and MCP access ^[143]. Scrunch AI offers the deepest citation-ownership and crawlability diagnostics with four-platform Core coverage ^[144].
