Your client’s rankings look fine. Then they ask ChatGPT for the best option in their category and a competitor gets the recommendation. Most agency reports can’t explain that gap.
It’s a costly one. Semrush’s research found the average AI search visitor is worth 4.4 times the average organic visitor when measured by conversion rate. Search isn’t shrinking, it’s splitting across Google results and AI answers, and clients need to win in both.
That split sits inside a wider shift the industry statistics already show, and most agency reporting has not caught up with it. Rankings are still measured monthly while the surface clients are judged on changes weekly.
I ranked seven platforms on how well they show who gets recommended, how each brand is described and which sources AI answers lean on. A clear SEO agency structure also helps decide who owns this reporting for each account.

How I Evaluated These Tools
Every platform was judged on one agency job: show a client where they stand against named competitors in AI answers, then explain why. I weighed competitor benchmarking, engine coverage, citation detail, multi-client pricing and client-ready reporting. Several tools gate engines by tier or sell them as add-ons, which changes the real price. Pricing reflects vendor pages as of September 2026.
1. Semrush
Semrush is a search visibility platform covering SEO, content, competitive research, PPC and AI visibility in one place. One login shows where a client ranks on Google and how AI answers position them against rivals.
Best for: Agencies reporting on SEO and AI search for several clients from one platform.
The AI Visibility Toolkit inside Semrush tracks brand mentions across ChatGPT, Gemini, Google AI Mode and AI Overviews. It sits on Semrush’s SEO dataset, which includes 43T+ backlinks.
Competitor research and Brand Performance
Enter a client’s domain and up to four competitors to find prompts where rivals get mentioned and your client doesn’t. That gap list doubles as a ready-made content brief.
Brand Performance then plots share of voice against sentiment, so you can spot a rival that’s loud but disliked. Narrative drivers explain the themes behind each perception, and a cited pages view shows which client URLs AI answers reference.
Prompt tracking and site audit
Prompt research works like keyword research for AI, and prompt tracking monitors the questions you choose over time. An AI-readiness site audit checks whether AI crawlers can access a site, which rules out a technical block before you rewrite content. For large multi-brand accounts, Enterprise AIO tracks mentions, share of voice and sentiment at scale.
Key strengths
- AI share of voice and sentiment sit next to rankings, backlinks and keyword data.
- Brand Performance, Competitor Research and Prompt Tracking feed into My Reports for presentation-ready client decks.
- Five AI surfaces are covered, including both Google AI experiences.
Limitations
- The Starter plan tracks AI brand performance for one domain and 50 prompts, so agencies with large rosters will need a higher tier.
- Competitor research compares up to four rivals at a time, which can feel tight in crowded categories.
Pricing: Billed annually, Semrush One, bundling the SEO and AI Visibility toolkits, starts at $165.17 per month. The AI Visibility Toolkit alone is $99 per month per domain.
2. Ahrefs Brand Radar
Ahrefs Brand Radar is built for market-wide benchmarking. Type in any brand and see how often AI answers mention it, with no setup.
Best for: Agencies needing a broad competitive snapshot before building a tracked prompt set.
Ahrefs lists 396M+ monthly search-backed prompts across AI Overviews, AI Mode, ChatGPT, Copilot, Gemini, Perplexity and Grok. Enter a client with its rivals to get an aggregated AI share of voice, alongside mentions, citations and impressions.
It also tracks branded search demand, the domains citing a brand and YouTube mentions. Those signals help explain why one brand wins the AI conversation, which makes a strong opening slide for a pitch.
Key strengths
- One of the largest AI prompt datasets, with unlimited projects.
Limitations
- Core Ahrefs plans include only small AI prompt allowances, so full coverage costs extra. Semrush One bundles SEO and AI visibility in one subscription.
- Custom prompt tracking is metered in checks, which makes costs harder to forecast.
Pricing: From $199 per month; the all-platforms tier is $699 per month. Custom prompt packages start at $50 per month and require a paid Ahrefs plan.
3. Profound
Profound is a dedicated AI visibility platform with no traditional SEO toolkit attached.
Best for: Standalone AI visibility programs with budget for multiple engines.
Profound records which brands appear for your prompts, how they’re described and which sources the answers draw on. That source view shows which publications feed a rival’s recommendations, so you know where outreach will matter most. Its Agents feature uses monthly credits to help produce content aimed at closing gaps.
Key strengths
- Source-level detail behind each mention, plus content support.
Limitations
- Starter tracks ChatGPT only; Growth covers three engines, and wider coverage needs Enterprise.
- No SEO integration, so rankings and backlinks live in a separate tool. Semrush keeps both in one platform.
- Agency client workspaces are priced per brand, which adds up across a roster.
Pricing: Starter is $99 per month and Growth $399 per month, both billed yearly. Enterprise is custom.
4. Similarweb
Similarweb’s AI Search Intelligence answers two client questions together: how visible are we in AI answers, and how much traffic does AI send?
Best for: Clients who want AI visibility tied to referral traffic.
AI Brand Visibility covers ChatGPT, Perplexity, Gemini and AI Mode, comparing a client with competitors across tracked topics. Citation Analysis names the domains and exact URLs that most influence answers, and Sentiment Analysis is included by default.
The AI Traffic module estimates AI chatbot referrals against competitors, down to the landing pages receiving them. Treat those figures as estimates and confirm with a client’s own analytics.
Key strengths
- Visibility, citations, sentiment and AI traffic in one package.
Limitations
- Visibility tracking covers four engines, without Copilot or AI Overviews.
- The entry plan includes one user and three months of history.
Pricing: AEO Intelligence is $99 per month with 150 tracked prompts. The $333 tier adds SEO and competitive intelligence.
5. Peec AI
Peec AI is a self-serve tracker that runs your prompts daily and logs how each brand appears.
Best for: Growing teams wanting daily tracking without an enterprise contract.
Peec shows a client’s share of voice against named rivals and groups cited pages by source type, such as brand sites, publishers or forums. Setup is quick, with suggested starter prompts based on a client’s site. Every plan includes unlimited users, which suits agencies where strategists, writers and account managers all need access.
Key strengths
- Daily tracking and unlimited seats on every plan.
Limitations
- Self-serve plans track three engines, with extras sold as add-ons.
- No technical audits or SEO workflow, which Semrush includes.
Pricing: Starter costs about $95 per month for 50 prompts and one project. Pro and Advanced raise the limits, and Enterprise is custom.
6. SE Ranking
SE Ranking adds AI tracking to a budget-friendly SEO suite through its AI Search add-on.
Best for: Smaller agencies watching costs.
The add-on monitors AI Overviews, AI Mode, ChatGPT and Perplexity, tracking mentions and cited sources for each query. Because it sits beside rank tracking, clients can see a page-one ranking next to a lost AI Overview. That side-by-side view is often the clearest way to explain a drop in clicks.
Key strengths
- AI and classic rank tracking in one affordable suite.
Limitations
- The add-on block on SE Ranking’s pricing page names four engines, so confirm Gemini coverage.
- AI features are lighter than dedicated trackers. Agencies ready to invest in growth get deeper AI and SEO data in Semrush.
Pricing: The Core plan starts at $129 per month, with the AI Search add-on billed on top.
7. Otterly.AI
Otterly.AI is the lowest-cost entry into AI monitoring on this list.
Best for: Lean teams testing AI visibility before a bigger commitment.
It tracks ChatGPT, AI Overviews, Perplexity and Copilot daily, with AI Mode and Gemini as paid add-ons. It logs which brands and domains appear per prompt and tracks brand sentiment. Every plan includes unlimited team members, and Standard and Premium add unlimited workspaces to keep clients separate.
Key strengths
- The lowest entry price here, with a free trial.
Limitations
- Lite includes just 15 prompts, and there’s no SEO toolkit.
Pricing: Lite is $29 per month for 15 prompts, Standard $189 for 100 and Premium $489 for 400.
Conclusion
Semrush is my top pick for agencies showing clients where they stand against competitors in AI answers. It pairs share of voice, sentiment and competitor gaps with the SEO data your team already reports on.
Ahrefs Brand Radar leads for wide market research, Profound for dedicated AI programs and Similarweb for traffic context. Peec AI, SE Ranking and Otterly.AI give smaller teams affordable starting points. Whichever you choose, pilot it with a fixed prompt set and the same named competitors.
FAQ
What’s the difference between a mention and a citation?
A mention names the brand in an AI answer. A citation links to a source page, which may not belong to that brand.
How do agencies measure competitor positioning in AI answers?
Most tools use share of voice, the percentage of mentions a brand earns versus rivals. Pairing it with sentiment shows whether a competitor is loud or genuinely favored.
What makes Semrush different from dedicated AI trackers?
Semrush combines AI visibility with a full SEO toolkit in one platform. Profound, Peec AI and Otterly.AI focus on AI answers only.
