While reviews matter, some are more important than the others. For example, Google reviews take the lion's share at 73%. Yelp, at a low 6%, takes the next place, and Facebook even lower, at 3%. Together these 3 account for most of the reviews adding up to a whopping 81%, The other sites combined make up the remaining 19%, which comprises your medical review sites, dental review sites, your AVVO and other trade specific medical, dental, and profession specific sites. So, whether you've been in business for years, or just starting out, focus your efforts on Google reviews, and on how to get more Google business reviews. Later we can talk about how to get reviews on Yelp and on other sites.
