Why We Ask You To Verify
A grade you can publish should only be created by someone who controls the site. Verifying takes one step — a meta tag, a small file or a DNS record — the same way search consoles confirm ownership. The four individual checks stay open to anyone checking a site they own or have permission to check.
These are passive, point-in-time checks of what your site serves publicly. They are not a guarantee that it is free of vulnerabilities.
