Website Grader

Enter any website and get a score out of 100 for SEO, speed, mobile, trust and AI search readiness, with a plain-English list of what to fix first.

How the score works

Each check passes, needs work or fails. Important checks like HTTPS, a mobile viewport and your page title count more than nice-to-haves like llms.txt. Each area gets a score out of 100, and the overall score is the weighted total.

What to fix first

  • Failed checks in Trust and Mobile: they cost customers on every visit.
  • Title, description and H1: the quickest SEO wins, and they shape how your link looks in Google.
  • Structured data: it helps Google show rich results and helps AI assistants recommend you.
  • Speed: compress images to WebP, lazy-load what is below the fold and cut unused scripts.

FAQs

What does the Website Grader check?

Over 25 checks across five areas: SEO basics like titles, descriptions and headings; speed signals like response time, page weight and blocking scripts; mobile setup; trust signals like HTTPS and contact details; and AI search readiness like structured data and FAQs.

Is this the same as Google PageSpeed Insights?

No. PageSpeed runs a full browser test of loading speed. This grader looks at the whole page from a marketer's view: can Google, AI assistants and customers understand and trust it? Use both together.

Why is my score different each time?

Server response time changes from moment to moment, so the Speed score can move a few points between runs. Everything else stays the same until the page changes.

What is AI search readiness?

How easily ChatGPT, Google AI Overviews and Perplexity can understand and quote your business. Structured data, clear FAQs and business details make the biggest difference.

Is it really free?

Yes. Grade as many pages as you like. If you want a human review with a prioritised fix list, request the free full audit under your results.
