Website Check
Enter your website address and get a free, instant report on performance, SEO, accessibility, and a few technical basics.
What does a website check actually measure?
This tool runs your page through Google’s own Lighthouse engine, the same technology behind PageSpeed Insights, and pulls out the four scores that matter most: performance, SEO, accessibility, and best practices. Performance covers how fast your page loads and becomes usable. SEO checks the basics search engines look for, like a title tag and a mobile viewport. Accessibility flags issues that make a site harder to use for people relying on screen readers or keyboard navigation. Best practices covers modern web standards, like serving images in the right format and avoiding known security issues.
How should I read my scores?
Scores run from 0 to 100. Above 90 is generally considered good, 50 to 89 means there is real room to improve, and under 50 signals problems worth fixing soon. A single low score rarely means your site is broken. It usually points to a handful of specific, fixable issues, like an oversized hero image or a missing meta description, not a full rebuild.

Why did my score change between two checks?
Performance scores in particular can shift a little between runs because they depend on live network conditions and server response times at the moment of the test. A difference of a few points between two checks is normal. A large, consistent drop usually means something changed on the site itself.
Is a 100 performance score realistic for a small business site?
It is achievable, but not always the right investment. Squeezing the last few points out of a performance score often costs disproportionate development time compared to fixing the accessibility and SEO basics first. We generally recommend getting every score comfortably into the 90s before chasing a perfect 100.
Does this check my whole site or just one page?
Just the single URL you enter. Different pages on the same site, especially the homepage versus a heavy product or blog page, can score quite differently. If you want a full-site picture, run the check on your homepage and your two or three most-visited pages separately.
