As a result, the team decided to replace the Norton Seal with TrustedSite trustmarks, but chose to continue displaying the GoDaddy security trust seal.

We hypothesized that displaying the TrustedSite badges across would lead to increased add to carts and transactions. Results indicated visitors who saw the TrustedSite badges added items to cart at a higher rate than those who did not see the badges. Based on the test results, we recommended they replace the competitor’s badges they were previously using with TrustedSite badging.
