I registered 4 products that had been selling well but with either very few or no reviews on 07/18. Since then I’ve received 12 total reviews over those 4 products. .A few of these reviews came over the last 1-2 months and the vast majority have been 4 and 5 stars.
As a customer I am only going to leave a review if the item is outstanding or a real dud, I don’t think I would respond to a $3 to $5 incentive (I actually did receive one such offer through this program but passed on it because I wasn’t motivated by the $3 and I didn’t want to leave a 3 star review based on my personal experience which might not be the same as that of a typical customer).
In hindsight, I think the ERP provides motivation for some people to leave reviews. From reading my own ERP reviews I think about half of those reviews could have happened organically but I’ll never know for sure. I was expecting the ERP to start getting results right away, but it took a while. Also, I don’t think the presence of reviews / stars has had an impact on monthly sales (again, I have no way of proving this, I can just say that sales didn’t double when I suddenly had 2 reviews).
