Bottom line: Review volume is one of the top factors shoppers consider when reading reviews, second only to star rating. There’s no magic number, but typically the more reviews the merrier.
Three ways you can increase review quantity without sacrificing quality:
Make it a priority to collect a high volume of reviews for the products in your catalog, and if you are a brand, leverage syndication networks to share natively collected reviews with retail partners.
To avoid launching a product without reviews, run a pre-launch product sampling campaign which involves distributing samples prior to launch, and then asking consumers to share their feedback by writing a review.
While email is the most common review collection method, there are others. Asking for reviews via text message and on store receipts are two such examples. Are you maximizing your opportunities to ask for reviews?
