Top 10 AEO Tools for Measuring AI Search Visibility

1. AEO Grader — Our own tool. The free check gives you an instant AI visibility estimate using Gemini with Google Search grounding, including an overall AEO score and recommendations. The paid multi-engine report queries ChatGPT, Claude, Gemini, and Perplexity directly to show how each one perceives your brand. Best for: quick brand audits and benchmarking. 2. Google Rich Results Test — While not AEO-specific, validating your structured data is a critical AEO step. Google's Rich Results Test is the tool Google recommends for validating structured data and previewing eligible Google Search features for your schema markup. 3. Schema Markup Validator — The Schema Markup Validator checks any Schema.org markup in JSON-LD, RDFa, or Microdata, not just the types Google uses for rich results. According to Schema.org's documentation, it is based on the former Google Structured Data Testing Tool and is provided by Google for the Schema.org community.

4. Profound — An AI marketing platform whose Answer Engine Insights feature analyzes where and how your brand appears in AI responses, tracking citations, sentiment, ranking, and competitive presence. Its engine coverage includes ChatGPT, Perplexity, Claude, Gemini, Microsoft Copilot, and Google AI Overviews. Profound's pricing page lists a free trial and custom enterprise pricing. Best for: larger teams that want ongoing competitive monitoring. 5. Otterly.ai — Monitors your brand's presence in AI search with scheduled daily tracking across ChatGPT, Google AI Overviews, Perplexity, and Microsoft Copilot, with other engines available as add-ons, plus content audits and recommendations. Otterly's pricing page lists plans starting at $29 per month. 6. Peec AI — Describes itself as AI search analytics for marketing teams, tracking visibility, position, sentiment, and share of voice against competitors across ChatGPT, Perplexity, and Gemini. See Peec AI's pricing page for current plans. 7. Knowatoa — An AI search visibility monitoring platform covering seven AI services, including ChatGPT, Claude, Gemini, Perplexity, Meta AI, and Google AI Overviews and AI Mode, with citation tracking, competitor gap analysis, and sentiment alerts. Knowatoa's pricing page lists plans starting at $59 per month. Pair any of these with the foundational entity optimization work that underpins all AEO.

8. Surfer SEO / Clearscope — While primarily SEO tools, their content optimization features help create the clear, comprehensive content that performs well in both search and AI answers. Use their content briefs as a starting point, then apply AEO-specific formatting. 9. Semrush / Ahrefs — Keyword research platforms like these are invaluable for AEO keyword research. In Semrush, the Keyword Magic Tool's Questions filter shows only keywords phrased as questions, which helps you find the exact phrases users ask AI models. 10. Screaming Frog — The Screaming Frog SEO Spider extracts and validates structured data against Schema.org and Google rich result features, and can crawl with an AI crawler or custom user agent to check what bots can reach. The free version crawls up to 500 URLs. Essential for the technical AEO side of your strategy.

You do not need all ten tools. The most effective AEO toolkit for most teams combines three categories: (1) a visibility scorer for periodic audits — the AEO Grader gives you a free estimate to start; (2) a mention tracking tool for ongoing monitoring — choose based on your budget and the AI models your audience uses most; (3) a structured data validator and crawler for technical audits. Start with the free tools to establish your baseline, then invest in premium monitoring tools as your AEO strategy matures and you need to track progress over time.
