Run a free Answer Engine Optimization audit. See your AEO score, what ChatGPT, Perplexity, and Gemini can crawl, and exactly how to fix robots.txt, schema markup, and llms.txt issues.
For marketers, SEO & AEO specialists, agencies, and founders. AEO Lab monitors GPTBot, ClaudeBot, PerplexityBot, and Google-Extended — the crawlers answer engines actually send.
Search engines and answer engines read the web differently. The site that ranks on Google can still be unreachable to the models people now ask first.
A single robots.txt rule can shut out GPTBot, ClaudeBot, or PerplexityBot while Google keeps indexing you — so traditional tools report a healthy site.
Missing llms.txt and thin schema leave answer engines without the structure they need to quote or attribute your pages.
You can't tell when AI crawlers visit, which pages they reach, or whether a change moved anything — so you're optimizing blind.
Rank trackers measure Google. They say nothing about whether ChatGPT, Perplexity, or Gemini can access and recommend you.
No setup project, no migration — start with an audit and grow into monitoring.
Enter a URL and get a 12-point AEO score with the exact signals that pass and fail — robots.txt, schema, llms.txt, and more.
Add one lightweight snippet to start recording when GPTBot, ClaudeBot, and Perplexity actually crawl your pages.
Watch AI referral traffic and your score over time, then work a prioritized fix list ranked by real visibility impact.
AEO Lab reads your robots.txt the way answer engines do and shows, per crawler, whether you're open or quietly blocked.
A live view of the traffic coming from ChatGPT, Perplexity, and Claude — so you can connect AI visibility to real sessions.
Every issue is ranked by impact, so critical blockers surface first and low-value busywork falls to the bottom.
Twelve technical checks confirm your pages can be reached, parsed, and indexed by AI systems — not just by Google.
Validates JSON-LD and your llms.txt so answer engines can recognize what your content is and cite it correctly.
Traditional tools cover SEO well. They weren't designed for the signals that determine whether AI answers include you.

AEO is the practice of making sure AI answer engines — ChatGPT, Perplexity, Claude, and Gemini — can reach your pages, understand their structure, and cite them in responses. Where SEO optimizes for ranked links, AEO optimizes for the moment a model decides whether your site is a trustworthy source. AEO Lab measures the 12 technical signals those systems rely on and tells you which ones you're failing.
Rank trackers and site auditors are built around Google's crawler and ranking model. They don't test whether GPTBot or ClaudeBot are allowed in your robots.txt, whether your llms.txt exists, or whether traffic is arriving from AI answers. A site can score perfectly in those tools and still be invisible to the engines people now ask — AEO Lab is built specifically for that gap.
Yes. Enter any URL and run the full 12-point audit instantly — no signup, no credit card, no account. Re-run it as often as you like. Paid plans add continuous monitoring, AI traffic insights, score history, and a dashboard, but the audit itself stays free.
Your score is the share of 12 AI-readiness checks your site passes: robots.txt access for major AI crawlers, llms.txt presence, JSON-LD and schema validity, meta directives, heading hierarchy, and content structure. Each failed check comes with a specific fix and an impact ranking, so the score is a to-do list, not just a number.
llms.txt is a plain-text file at your domain root that tells AI systems what your site covers and how your content should be used. Answer engines increasingly read it alongside robots.txt to decide what to surface. If you're missing it or it's misconfigured, the audit flags it — and the built-in generator creates a valid one in seconds.
Re-audit after any robots.txt change, schema update, or significant content restructure. For live sites, monthly is a good baseline — AI crawler user-agents and access policies change faster than traditional search. On Pro, continuous monitoring does this for you and alerts you when something regresses.
