Over the past couple of years, i have had several 5 star reviews on Yelp. Every year I get a call from their sales agent who claim that I should advertise with them to keep my competitors from getting the business. They ask you what a new job is worth, then equate a phone call as being the reason you get a new job. So they ask for about $300 a month and tells you that they will get you lead which will allow you to recover the cost. If you delcine their pitch, after a little while they claim that the reviews which were live are no longer valid because their secret program has screened the reviewer out as not being a quality Yelper. So in their opinion, everyone opinion does not have the same weight. If you really think about it, as a business, the opinion of a guy who goes around and spend 10 - 20 dollar per transactions, weights more than an individual who would go out and spend $10,000 or more in one transaction. So quality customer reviews are overlooked and hidden because they don't review as frequently. The shake down is the same as someone coming and asking your to pay protection, because they are protecting you from them.
