Who it's for

The same audit, in your language

From the audit you already run to the page you just published, OctoCheck speaks to whoever owns the fix.

For SEO specialists

Take your audits into AI search

Run the same technical checks you already trust, now mapped to how LLMs crawl, parse, and cite a page. Spot what AI engines can and can't read before it costs you a citation. Every fix comes ranked by impact, so the highest-value work goes first.

For marketers & content teams

See what AI answers pick up, and why

Find out why AI answers surface your content or skip it, from citation-ready passages to coverage gaps and stale claims. Every issue comes with a plain-language fix you can ship yourself. No developer in the loop, no guesswork about what to change.

For developers

Technical checks on any page, in seconds

Crawlability, schema, rendering, headers, and the accessibility tree agents actually read, all in a single pass on any page. Compare the raw HTML a bot fetches against the rendered DOM a person sees. Catch what client-side JavaScript hides from non-rendering crawlers.

For site owners

Know if AI can find and trust your site

Get one readiness score that tells you, in plain language, whether AI search can find, trust, and cite your site. Then work through the fixes that matter most first. Each one is explained simply, with no jargon and no guesswork about where to start.

Frequently asked questions

Who is OctoCheck for?
Anyone who owns a page and wants AI answers to use it: SEO specialists adding AI search to audits they already run, marketers who write the content, developers who ship the markup, and site owners who need to know whether their site is readable at all.
Do I need to be technical to use it?
No. Every finding is written in plain language with the fix beside it.
Which AI engines does it check?
It covers the major AI answer engines, ChatGPT, Perplexity, Claude, Gemini, Google AI Overviews, Copilot, and more.
Is this just SEO?
It builds on SEO but focuses on what AI answer engines need to read, trust, and cite your page. It complements your SEO work, it does not replace it.
How accurate are the checks?
Every check is grounded in official guidance from search and AI providers and in published research, and we update them as the field changes.
What's in Pro?
The free audit covers everything OctoCheck can check inside your browser. Pro adds deeper AI-powered content checks, like whether your page is citation-ready, has gaps in its answer, or has weak definitions, that run beyond your browser. Sign in to unlock them.
