Free single-page check
SEO and accessibility page check
Enter one public webpage. This tool reads its HTML source and checks the page title, description, headings, image alt attributes, indexing signals, and basic loading clues.
What this checks
Page identity: title, description, canonical address, and indexing instruction.
Headings: H1 count and skipped heading levels in the source.
Images: missing, empty, and present alt attributes, with up to 10 sources listed.
Source loading: HTML fetch time and size, external scripts, deferred scripts, and lazy-loading hints.
Important limit: This is not a WCAG compliance test or a full performance lab. It cannot test keyboard use, color contrast, screen-reader behavior, or content added later by JavaScript.
