How the Site Checker works
The Site Checker reads the public homepage of the address you enter, the same way a search engine or a browser would, and runs 22 checks worth 100 points in total. It looks at HTTPS, load time, the page title and meta description, social preview tags, a canonical link, the mobile viewport tag, analytics set-up, links to privacy, cookie and terms pages, a contact link, icons and six common website files such as robots.txt and sitemap.xml.
Every point you miss is listed with the reason and a suggested fix, so the score always adds up. If something could not be checked, for example because the site did not respond or a consent tool hides the analytics tag, the result says "Not tested" and the scan is marked incomplete rather than failed. You can download the result as a PDF report.
When to use it
Run it before a campaign launches, after a website change, and before applying for programmes such as advertising networks that look at a site's basics. It is a quick health check, not a full audit: it reads the homepage, not every page, and it cannot see inside logged-in areas.
A worked example
A small charity checks its site a week before an appeal. It scores 74. The breakdown shows no meta description, no social preview image and no sitemap.xml. They use the generators lower on this page to create the missing files, ask their web volunteer to add the two tags, and run the check again. The score rises, and the appeal link now shows a proper preview when shared.
For what each check means read the Site Checker Guide, and before any launch work through A pre-launch landing page checklist.
