Do Security Seals on eCommerce Websites Help?

Yes, absolutely. In a recent study by McAfee of over 165 million shoppers, it was observed that those B2C sites that had some kind of security seals over them were able to convince the customers better in making a purchase than those websites that did not have any kind of security seals. Here are the results from the study:

11% increase in transactions in the presence of a security seal on the ecommerce site
Average delay time in making a purchase (offering credit card) : 34 hours
