Early Findings

Ways To Get Customers Write a Review

Make it easy for Consumers.

  • Etsy uses text messaging and emails to ask buyers to write a review. According to WSJ, Etsy reported that 25% of all their purchases result in a review.

Incentives/ Reward Consumers who Review

  • Some companies offer rewards/incentives to those who leave reviews. Zappo gives out $10 credit or 100 points for every consumer who writes a review. This does not mean to buy reviews, rather can offer points in the business's customer loyalty program.

Pop-Up Forms + Follow-Up Emails

  • John Holloway of NoExam states that they use pop-up forms on their business site to get reviews from consumers after they have purchased a product. After two weeks, the company sends a follow-up email address asking clients to write a more detailed review, and they have collected above 1,000 customer reviews using this strategy.
  • Fiona Kay from Nigel Wright Group states that the company sends out customer feedback emails every month, asking the clients to fill a 30-second survey. This strategy has seen the company increase the number of reviews on their products.
