On-page SEO checker

The page title and meta description, the H1 and section headings, the amount of text, image alt text, internal links, whether the page can be indexed, its canonical address, robots.txt and sitemap, HTTPS, mobile setup, structured data and social sharing tags.

Every check that passes counts as one point, a check marked "to check" counts as half, and a check marked "to fix" counts as zero. The score is the share of points earned.

No. It checks what is on the page itself. Backlinks, rankings and search volume need separate data and are part of a full SEO audit.

On-page SEO is everything you control on the page itself: the title, headings, text, images, links and the technical tags that tell search engines what the page is about.

Around 30 to 60 characters. Shorter titles waste space, and longer ones are often cut off in search results.

Yes. The checker reads any public page, so you can compare a competitor's title, headings, content length and structured data with your own. It does not show their rankings, traffic or backlinks.

The canonical tag points to a different address than the one you entered. That is fine when the other address is the main version of the page. It is a problem when it points to an unrelated page, because search engines may then ignore the page you checked.

After every meaningful change to the page, such as a redesign, a new template or rewritten content, and after a plugin or theme update. For pages that do not change, a check every few months is enough.
