SiteAudit — Website Checker

Audit any web page for SEO, accessibility and technical problems. Get a score out of 100 and a plain-English fix list.

SiteAudit checks the web page you are on and tells you what is wrong with it — in plain English, ranked by what matters most. Open the extension on any page. You get a score out of 100, a grade, and a breakdown across four areas. Every failed check explains what was found and what to do about it. No jargon, no black box. 25 CHECKS ACROSS FOUR AREAS Technical HTTPS, page title, meta description, mobile viewport, canonical tag, indexability, character encoding, favicon, language, mixed content. Content Exactly one H1, heading order, enough page content, social sharing tags, structured data. Accessibility Image alt text, form field labels, link text, duplicate IDs, button names, frame titles. Links and safety Safe new-tab links, insecure resources, deprecated HTML, script count. WHY SITEAUDIT IS DIFFERENT Most audit tools give you a score and leave you to work out what it means. SiteAudit tells you the fix. Each failing check states exactly what was found and what to change. PRIVATE BY DESIGN • The audit runs entirely in your browser. • Nothing is uploaded. No account, no sign-up, no analytics, no tracking. • No cookies, no remote code, no network requests. • It reads only the page you are actively viewing, and only when you click the extension. WHO IT IS FOR Anyone who maintains a website — web designers, developers, marketers and business owners. Useful before launch, and useful as a monthly sanity check. Made by Web Design Products, based in Shropshire, UK, with twenty years of building and maintaining websites behind it. Free. No account needed.
