One of the ways which you can gain further credibility in the eyes of your readers and visitors is to have independent third party reviews or endorsers.  While testimonials are very powerful in terms of how much you can convey the actual results and benefits of using the product, sometimes visitors wonder if that person is a friend, cousin, former roommate, etc.

A review from a third party, respected authority COMBINED with testimonials is usually enough to at least remove some of the reader's fear of risk.  Reviews from respected individuals, national magazines, and other sources can be very helpful in your efforts to increase click-through and conversion rates.
