I'm pretty new to Google Merchant Center, but I've noticed that reviews seem to be very important in ranking well lately. I have a review strategy in place - we have many happy customers, and we're able to offer a discount as an incentive to get customers to review their experience with our store.
The problem is, I'm having some issue figuring out which review sources we should focus on. I've read all of the following can influence Google reviews, but I hoping anyone with some experience here could point me in the right direction of which ones to focus on. thanks!
