The seal is not an image you save and paste: our server draws it every time the page loads. It lights up only on the verified site. Pasted elsewhere, it answers “not valid on this site”.
A photograph stays a photograph. That is why a click opens the verification page: status, dates, domain and a signature anyone can check with our public key. Ours is lit; the one for your site is ready, for social media too.
The seal does not stop anyone cloning a site: it only shows that the clone has no valid seal. It depends on which page the request comes from, so a browser that does not send that information shows “not valid” even on the real site. And when a seal is turned off, the change arrives within about a minute and does not affect a page that is already open.
