Some interesting stats on trust seals. Its painfully obvious that people (well atleast this set) trust Norton over the alternatives.
Whenever we go to a website we have never been to before, there is a small voice of doubt inside our head, asking "Why should I trust this site? What if I place the order and don’t receive the goods? What if their payment system isn’t secure and my private information leaks out to the public?" And just like that, we talk themselves out of an online purchase in a matter of seconds.
