Amazon Buy Box/Featured Merchant algorithm rigging
An investigation by The Markup indicates that Amazon has been regularly placing its own brand products above those of competitor products.
Based on data provided by 3,400 product searchers in January 2021, the report finds that Amazon brands and exclusives, whilst only accounting for a small proportion of products on the company's platform, receive an 'outsized portion of the top spot on search results.'
Over 150 Amazon house brands and 137,000 unique house brand and exclusive products were identified during the investigation.
Purpose: Rank content/search results
