Free Website Grader

Grade any website 0-100 on performance, SEO, best practices and accessibility. We run Google PageSpeed for both mobile and desktop, plus Core Web Vitals, CMS and SSL.

What the grade means

The overall grade combines four Google Lighthouse categories, performance (weighted highest), SEO, best practices and accessibility, into a single 0-100 score. We run PageSpeed separately for mobile and desktop, and pull real-user Core Web Vitals (LCP, CLS, INP) where available.

A low grade usually means slow load times, weak SEO or an outdated build, exactly the businesses a web design agency should be reaching out to. LeadWebia grades every lead automatically so agencies can prioritize the worst sites first.

Frequently asked

What does the website grader measure?expand_more

It runs Google PageSpeed (Lighthouse) for mobile and desktop, scores performance, SEO, best practices and accessibility, then combines the mobile scores into one overall grade. It also reports Core Web Vitals, the CMS and SSL status.

How long does it take?expand_more

A full grade runs two live Lighthouse audits, so it usually takes 10-30 seconds. Results are cached, so re-checking the same site is instant.

What is a good score?expand_more

Each category is scored 0-100: 90+ is good (green), 50-89 needs work (amber), and under 50 is poor (red). Most small-business sites score well below 90 on performance.

Is it free?expand_more
