I know Angie's List, Yelp and TripAdvisor focus heavily on reviews. For a business site that includes professionals, are reviews a good feature?
"YES" - current, high-profile (known business representatives) reviews establish realtime credibility.
"NO" - outdated, abstract reviews can appear desperate.
Personally, I stay away from self-promoting reviews in my marketing. New clients can see portfolio examples of my work from clients past and present .
The quality and craftsmanship of your product or service far outweighs any referral.
