Your store gets orders, but the review section stays quiet.
That does not necessarily mean customers are unhappy. They received their order, tried the product and moved on. Returning to your store to write a review probably was not on their to-do list.
Switching to a new reviews module in PrestaShop? One thing you probably don’t want to lose is all the reviews your customers have already written.
You worked hard to collect product reviews. Now one of your best-selling products has 87 of them.
That should be great for conversion — except most customers are not going to read 87 reviews.
