Site Seals are highly identifiable visual images—static or dynamic—that appear on webpages to assure visitors their connection is encrypted and they’re safe on your site. Think of the Better Business Bureau trust mark, only related to website security. They help you differentiate your site from competitors and give visitors an extra level of assurance that boosts trust and conversions. Domain Validation (DV) SSL Certificates have a static Site Seal. Organizational Validation (OV) and Extended Validation (EV) SSL Certificates have a dynamic clickable Site Seal.
