You should never use use a site seal. Site seals train people improper ways of confirming whether or not they have a secure SSL connection. To correctly determine if you have a secure connection look for the lock icon on your browser and verify the credentials by double clicking the lock. Also make sure the web address has a "https" prefix not "http".
So that I do not give to much information away on how to fake a site seal, the images below are deliberately not complete. Additional steps could be taken to create a more believable affect. All trademarks are the property of their respective owners.
