What is a Site Seal?

SSL site seals are intended to reassure website visitors that a site is trustworthy. The marketing copy from many Certificate Authorities claims that placing their seal on your site will gain the confidence of your customers and therefore improve your conversion rates. But which site seal is the most effective at doing this job?

WhichSSL.com recently conducted a survey of online shoppers to identify which site seal they trusted the most. We presented respondents with site seals from the major SSL vendors as well as some seals from non-SSL companies such as TRUSTe and the BBB. We asked them to pick the seal they trusted most.
