Registering for Accreditation:
There are businesses that provide a “Seal of Approval accreditation” service to websites.  The seal is supposed to be a sign to anyone visiting your website that you engage in fair business practices.  Companies pay for this service in order to give credibility to their website.  The drawback is that many of the companies that provide this service do so fraudulently.  They take your money and give you a seal do display on your website.  However, it is meaningless because the seal of approval is based solely on the organization offering the service.

Protect your business: 
Get this service from the BBB.  The BBB has a reputable history and is recognized by consumers as a leading force in this area.
