Top 10 AEO Tools for Measuring AI Search Visibility

1. AEO Grader — Our own free tool analyzes how AI models perceive your brand across four major engines (ChatGPT, Claude, Gemini, Perplexity). It provides an overall AEO score, brand sentiment analysis, model-by-model rankings, and actionable optimization recommendations. 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. This free tool checks whether your schema markup is properly implemented and eligible for rich results. 3. Schema Markup Validator — The official Schema.org validator tests your JSON-LD against the full schema specification, catching errors that Google's tool might miss.

4. Profound — Tracks your AI share of voice across multiple LLMs over time. Monitors how often your brand is mentioned, what context it appears in, and how your visibility trends compare to competitors. Best for: ongoing competitive monitoring. 5. Otterly.ai — Monitors your brand's presence in AI search results with scheduled tracking and alerts. Useful for detecting sudden changes in how AI models describe your brand. 6. Peec AI — Specializes in tracking brand mentions across LLM outputs. Provides sentiment analysis of how different AI models characterize your brand. 7. Knowatoa — Focuses on entity authority measurement, tracking how well AI models recognize your brand as a distinct entity. Useful for 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 — Their question-based keyword research features are invaluable for AEO keyword research. Filter for question queries to find the exact phrases users ask AI models. 10. Screaming Frog — Crawl your site to audit schema markup implementation, identify pages missing structured data, and verify that AI crawlers can access your content. 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 handles this for free; (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.
