BeginBiz Affiliate Marketing Blog has a nice post were he found a great web site for called "The Web Credibility Project" – it's part of the Persuasive Technology Lab at Stanford University.

This is an ongoing project that is doing the following:

"Performing quantitative research on Web credibility.
Collecting all public information on Web credibility.

Acting as a clearinghouse for this information.

Facilitating research and discussion about Web credibility.

Helping designers create credible Web sites."

Great numbers, great bullets of do's and don'ts that were statistically researched … I guess I'll print this whole article on Web Credibility and read it completely…
