12 technical checks of AI search visibility: crawler access, content in raw HTML, Schema.org markup, sitemap, speed. The same checks I run in paid GEO audits, pointed at your domain.
Free. No AI involved: deterministic rules, an honest result.
The same rules my own site passes at 95+ out of 100, and you can verify that
No AI inside: deterministic checks, the result cannot hallucinate
The report opens instantly after one email, and is yours to share
It sends at most eight ordinary requests to pages your server already serves publicly: the home page, robots.txt, sitemap, llms.txt, a missing-page probe and up to two inner pages. No login, nothing hidden, nothing stored from your content beyond the technical findings. It identifies itself as SiteCheck/1.0 with a link back to this page. If you would rather it stayed away, add a Disallow for SiteCheck in your robots.txt and it will read robots.txt only and crawl nothing further, or write to me and I will block your domain.
Generative Engine Optimization: making your site readable and quotable for AI assistants like ChatGPT, Claude and Perplexity, the way SEO does for Google. The technical base is crawler access, content in raw HTML and entity markup.
Most AI crawlers do not execute JavaScript. If your content appears only after scripts run, assistants receive an empty page. This check fetches your site exactly the way they do.
No, that is the finding itself. If our scanner gets a challenge page, ChatGPT's crawler gets it too. Allowlist verified AI crawlers if you want assistants to read the site.
Measurement and a plan: control prompts in four assistants (ChatGPT, Claude, Perplexity, Gemini) before and after, content and entity work, and a prioritized fix list for your team. Automation cannot do that part.
