How the free check works

Your website, public information

The check reads your website’s main page and the public robots.txt and optional llms.txt files on the submitted host. It does not crawl your entire website, use your logins, access private analytics or change your website.

What we inspect

• SEO foundations: page descriptions and heading structure.
• Business identity: JSON-LD structured data and organization information.
• Crawler instructions: the public robots.txt rules relevant to supported user agents.
• Content structure: information available in the retrieved HTML, without executing the page’s JavaScript.

Evidence and coverage

Useful advice shows its working: connect each finding to public information, keep unavailable checks visible, and review any suggested change yourself.

Each finding explains what was retrieved, why it matters and a next step. Observed means usable information was retrieved. Couldn’t check means a request failed, was blocked or produced insufficient information. Not checked means the check did not run. A timeout is not evidence that your SEO failed. The report shows the actual target and observation time.

This release presents coverage and evidence rather than a composite score or letter grade.

Search crawlers and training crawlers differ

Robots instructions are declarations, not proof that a bot visited or complied. GPTBot is distinct from OpenAI’s search crawler, OAI-SearchBot. Google-Extended governs certain AI uses; it does not control inclusion in Google Search. Access for a training crawler does not establish search visibility or a recommendation.

Optional llms.txt

llms.txt is a proposed Markdown convention for presenting useful website information to language models. It is optional and ungraded here. Its presence or absence does not establish AI visibility. It is not a robots.txt access-control file. See the llms.txt proposal.

Drafts need your review

Suggested structured data and other drafts are starting points. Confirm every business fact, replace placeholders, validate the markup and publish deliberately. The check does not install changes automatically.

Limits and report links

This does not measure rankings, backlinks, AI mentions, citations or recommendations. A main-page snapshot may differ from browser-rendered content or a later visit. Stored report links expire after 30 days; expiry does not establish deletion of underlying records. Anyone with a valid report link may read that report, so share it deliberately.
