How to use the Accessibility Checker

Accessibility Checker gives you SEO insights without sending your data to third parties. Open the page, enter the URL or paste the HTML content you want to analyse, and the tool examines it client-side. The results are organised by category — meta tags, content structure, technical elements — making it easy to prioritise fixes.

Why use the Accessibility Checker

What makes Accessibility Checker different from dedicated SEO platforms is the instant, focused analysis. You do not need to navigate a complex dashboard with dozens of metrics you do not need. Paste a URL, get the key on-page factors — title, description, headers, canonical, structured data — and act on the findings.

When to use Accessibility Checker

Reach for Accessibility Checker during content optimisation rounds when you are refining title tags and meta descriptions to fit search engine length limits. Preview how your page will appear in search results, adjust the copy, and iterate until every character counts.

Key features of Accessibility Checker

With Accessibility Checker you can audit, analyse, and optimise SEO elements without exposing your research or client data. The tool works offline after first load and delivers results in real time with no arbitrary daily limits.

Common use cases for Accessibility Checker

Typical SEO scenarios: a content marketer previews how a blog post will appear in Google search results before publishing; an SEO specialist checks whether recommended snippet lengths are being respected across a site's template files; and a site owner verifies that canonical tags are correctly set after a site migration.
