A site seal is a badge from the certificate authority that shows visitors your site is secured and, for OV and EV certificates, that your organisation was verified. Whether a product includes a seal, and which type, is shown on its product page.
Static vs dynamic seals
A static seal is a simple image confirming the site is secured. A dynamic seal is interactive: visitors can click it to see live details of your certificate and, for OV/EV, your verified organisation name. Dynamic seals carry more weight because clicking them opens a verification page from the CA for your domain, which a copied image can't reproduce.
What a seal actually signals
- Encryption: traffic to the site is protected.
- Verified identity (OV/EV): a checked organisation stands behind the site.
- Reassurance where it matters: on login and checkout pages, where visitors decide whether to trust you.
How to add it and where to place it
Copy the seal code for your certificate and paste it into your site's template. Add it once to a shared footer so it appears site-wide, and make sure it's visible on checkout and login pages. A dynamic seal is a small script from the CA. If your checkout handles payments, add the seal script to your list of approved payment-page scripts.
Common questions
Do all certificates include a site seal?
No. Check the "Site Seal" row on the product page.
Will the seal slow my site?
A dynamic seal loads a small script from the CA. Place it in the footer so it loads after your content.
Does a seal replace the padlock?
No. The padlock comes from the certificate itself; the seal is an extra visual reassurance.
