What AI SEO tools check
AI SEO — also called answer engine optimization (AEO) or generative engine optimization (GEO) — is about being included and cited when ChatGPT, Perplexity, Gemini, Claude or Google AI Overviews answer a question. Engines retrieve pages first, then write the answer, so the work splits in two.
The first half is technical: can AI crawlers reach your pages, is the content in the HTML without JavaScript, and is it structured so the right passage can be found? The crawler, llms.txt, schema and on-page tools here cover that. The second half is presence: are you actually named for the prompts your buyers ask, and which sources do engines trust? The AI visibility checker gives a free first read; aeotime tracks it over time.
FAQ
Questions
Are these AI SEO tools really free?+
Yes. Every tool on this page works without an account. Checks that fetch a URL have a basic rate limit to keep the service fast for everyone.
Which tool should I start with?+
Start with the AI visibility checker to see whether AI engines mention you, then the AI crawler checker and AEO checker to find technical reasons if they don't. Those three cover most problems.
Do the tools store my data?+
Generators and text tools run entirely in your browser. URL checkers fetch the public page you enter and return the result; they don't need or store any login.
How are the free tools different from aeotime's paid plan?+
The tools give you a one-time snapshot. The aeotime plan tracks your prompts across ChatGPT, Perplexity, Gemini, Claude, Google AI Overviews, AI Mode, Grok and DeepSeek on a schedule, with competitor share of voice, citations and alerts.
