Testimonials and reviews online continue to grow in importance, not just in influencing buyer behavior, but in generating organic traffic to websites via Search Engine Optimization. Reviews can be posted on a variety of online portals, now ranging from the business website to known reputation sites like Yelp and TripAdvisor, to industry-specific sites like Avvo for lawyers, HealthGrades for doctors, Trulia for realtors and HomeAdvisor for contractors, to social media channels like Facebook and Google+.
