About RateMySite.io

RateMySite.io is an independent website intelligence platform. We grade any website on the internet across performance, SEO, accessibility and AI visibility — then translate the results into something a human can actually understand: a letter grade from A+ to F.

How it works

1. You enter a website URL.
2. We run a full performance audit on both mobile and desktop.
3. We calculate a weighted overall score and a letter grade.
4. We generate plain-English insights and a prioritized improvement checklist.
5. Every audit gets its own permanent, shareable report page.

No AI. No guesswork.

We do not use AI to generate scores or insights. Every number on this site is derived from open, industry-standard web performance measurements. Every recommendation is deterministic.
