Website checker for llms.txt, JSON-LD, and AI crawler readiness
Check any public website for llms.txt, JSON-LD structured data, robots.txt AI crawler rules, sitemap discovery, canonical tags, and homepage metadata.
Check your website before AI crawlers and search engines do
See what machines can find, understand, and access, then get a clear next step.
Can AI find your site?
Checks your sitemap, discovery links, and public pages.
Can AI understand your pages?
Checks content, structured information, and machine-readable versions.
Are your access rules clear?
Checks crawler rules and whether important AI services receive a usable response.
What this website checker checks
The check reads public signals already available on your website. It does not log in, change your pages, or install anything.
Pages and discovery
Your homepage, one internal page, sitemap discovery, canonical URLs, and the links machines can use to find important content.
Content and structured data
Page titles, descriptions, readable HTML, and JSON-LD structured data that helps search engines and AI systems interpret a page.
AI-readable files
Public llms.txt files, markdown alternatives, and other machine-readable versions advertised by the website.
Crawler access
robots.txt rules and live responses for common AI crawlers, so you can see what is allowed, blocked, or difficult to retrieve.
How the result is decided
Every finding is based on a response the checker received. Results are labelled looks good, needs attention, or action required. There is no invented score. The checker samples one homepage and one internal page, so it gives a useful first view without crawling your whole site.
Frequently asked questions
What does the website checker inspect?
It reads your public homepage and one internal page, then checks discovery links, sitemap and canonical signals, readable HTML, JSON-LD, llms.txt and markdown alternatives, robots.txt rules, and live responses for common AI crawlers.
Does the checker change or install anything on my website?
No. It only makes read-only requests to public URLs. It does not log in, edit a page, install a package, or crawl your entire website.
Is this the same as the security scan?
No. The website checker focuses on whether machines can find, understand, and access your content. The security scan focuses on public safety signals such as HTTPS, response headers, cookie flags, mixed content, security.txt, and public DNS records.
Why does the checker not give a score?
A single score can hide the issue that matters. The checker reports evidence-based findings as looks good, needs attention, or action required, and gives a practical next step for each result.
