RuescanFree site check for AI and search readiness
Short answer: Ruescan is a free site check that looks at the technical signals that affect whether a site shows up on Google and in AI answers from ChatGPT, Claude and Perplexity. It reads the home page, robots.txt, the sitemap and llms.txt, measures mobile speed with Google PageSpeed, and lists findings in 6 areas by importance. No sign-up; it usually takes less than a minute.

Every finding, the evidence for each and the order to fix them in, plus Rues’s own reading. Write in if you want it; you will hear back through the contact you leave.
Only the findings are kept (90 days); the IP address and the site’s text are not stored. Your contact details are used for this request only.
01What we look at
Six areas, a few checks each. Everything is read from the public side of the site; no login, password or code access is needed.
- 01AI bots and accessDoes the home page open, can robots.txt be read; are AI search bots such as OAI-SearchBot, Claude-SearchBot and PerplexityBot and training bots such as GPTBot, ClaudeBot and Google-Extended allowed.
- 02Sitemap and indexingIs there a sitemap, is it listed in robots.txt, does it carry addresses and dates; is the home page noindex, where does the canonical tag point.
- 03AI-ready contentDoes the text come from the server or from JavaScript; is there an llms.txt; the H1 heading and image alt text.
- 04Structured dataIs there JSON-LD, is it valid JSON; identity types such as Organization and WebSite, and sameAs account links.
- 05Meta and sharingTitle and description presence and length, page language, hreflang, Open Graph and twitter:card tags, the mobile viewport tag.
- 06Speed and securityHTTPS and the redirect from HTTP, the redirect chain, HSTS and other security headers, server response time and the Google PageSpeed mobile test (score, LCP, CLS).
02Frequently asked questions
What the tool does, what it does not do, and what data it keeps.
- What does Ruescan check?
- Ruescan is a site check that reads only the home page and the robots.txt, sitemap and llms.txt files at the root. For the home page it looks at AI bot access in robots.txt, structured data, meta and sharing tags, HTTPS and security headers. If Google PageSpeed Insights can run at that moment, it adds the mobile speed score.
- What does the tool not do?
- It does not crawl the site’s other pages, run JavaScript, measure whether the site is mentioned in AI answers, predict rankings or traffic, or change anything. The findings are automatic hints drawn from the files it reads; they do not replace a review by an expert.
- Is Ruescan paid, do I need to sign up?
- No. The check is free and needs no sign-up. To prevent abuse, at most 3 checks per minute are allowed from the same connection, and there is a daily limit for the whole site.
- Why are some findings shown only as a number?
- The short report shows the most important finding in each area with its explanation and counts the rest. If you want to see every finding, you can request the full report; Rues gets back to you through the contact you leave.
- What data is kept?
- The checked domain, address and findings are kept for 90 days. The IP address is not stored; it is only used as a short-lived key for the rate limit. The site’s text and any personal details on the page are not stored.
- Do I have to allow AI bots?
- Search bots (OAI-SearchBot, Claude-SearchBot, PerplexityBot) read the site while answering; if they are blocked, the site may not show up as a source in those answers. Blocking training bots (GPTBot, ClaudeBot, Google-Extended) can be a choice; the tool shows it separately and with lower importance.
- Do I need llms.txt?
- llms.txt is a new proposal (llmstxt.org) that gives AI tools a short index of the site. Its effect is not proven yet, so a missing file is shown with low importance.
- Where does the speed score come from?
- From the Google PageSpeed Insights mobile test: the performance score, LCP and CLS. If Google cannot run the test at that moment, the speed area says "Speed could not be measured right now" and the other checks still finish.
