- Social & rich results: Open Graph and X card tags for link previews, and JSON-LD structured data types.
- AI search: whether GPTBot, ClaudeBot, PerplexityBot and Google-Extended are blocked, llms.txt, and content that only appears after JavaScript runs.

Frequently asked questions
Is this website auditor really free?
Yes. No sign-up, no email gate and no watermark on the report. To keep it fast for everyone there is a limit of about 40 audits an hour per network, and results are cached for an hour.
What does a website audit check?
The technical things that decide whether a page can be found and shown well: does it return 200, is it indexable, does it have a canonical, robots.txt and sitemap, are the title, description and headings right, do shared links get a preview, is there structured data, is it on HTTPS, and how fast it loads for real visitors (Core Web Vitals).
Why is my PageSpeed score different every time I test?
The lab score comes from one simulated page load, so network and server timing move it by a few points between runs. The "real visitors" numbers from the Chrome UX Report are a 28-day average of actual Chrome users and are what Google uses for ranking. Trust those more when they are available.
My site passes the audit. Why is it still not ranking?
An audit checks the technical foundation, and a clean result means nothing is stopping Google. Ranking then depends on whether the page answers the search better than the competition: matching the intent, depth of content, links from other sites and local signals. That is where most of the work is.
Does it work on sites built with React, Vue or other JavaScript frameworks?
Yes. The SEO checks read the raw HTML, the same way most AI crawlers and link previews do, so if your content only appears after JavaScript runs you will see a warning. Googlebot does render JavaScript, but later and less reliably. The PageSpeed test loads the page in a real Chrome browser.
