Amazon.com Inc. is asking online shoppers to provide information about product testimonials they’ve posted on TikTok, YouTube and Instagram, suggesting the e-commerce giant is more aggressively targeting paid reviews that merchants can use to gain a competitive edge. In a questionnaire sent to a reviewer and seen by Bloomberg, a member of the company’s product review team wrote: “We are researching reviews and would like to talk to you about the interaction you had with the seller on this product.” Eleven questions followed, including one that asked: “Can you describe the work you’ve done for this seller as an influencer (eg posted videos on YouTube, TikTok, Instagram etc.)?” Amazon’s campaign coincides with a government clampdown on paid product reviews.
