About our website checker

What it does

When someone asks for a Free Website Checkup of a website, our checker reads that website’s public pages and reports what helps or gets in the way of visitors: the message, the path to booking, search basics, mobile use, trust signals and tracking. It only runs when a person asks for a checkup, and the number of checkups per day is limited.

What it reads, and what it never does

It reads robots.txt, the sitemap, llms.txt and up to 15 public pages, one page at a time with a short pause between them, and takes phone and desktop screenshots of two of them. Page speed is measured by Google PageSpeed Insights, so that test comes from Google, not from us.

It only reads. It doesn’t log in, fill in or send forms, click buttons, buy anything or create accounts, and it never tries to get past a login, a paywall or bot protection. If a website shows a security check instead of its page, the checkup stops there and says so.

How it identifies itself

Every request carries the user agent RevRxAICheckup/1.0 with a link to this page. Requests to the website being checked are also signed with Web Bot Auth (HTTP Message Signatures, RFC 9421). The Signature-Agent header points to our key directory at /.well-known/http-message-signatures-directory, so a site, or a service like Cloudflare, can confirm a request really came from us. Our requests don’t come from fixed IP addresses, so please use the signature, not the IP address, to recognise them.

Robots.txt and slowing down

The checker follows robots.txt rules for RevRxAICheckup (and for its earlier name, RevRxAuditor). Pages a site excludes are skipped and listed as skipped, not counted as errors. If a website asks it to slow down (HTTP 429) twice, it stops checking more pages.

How to block it

Add these lines to your robots.txt and the checker will not read your pages:

User-agent: RevRxAICheckup
Disallow: /
