  eBay Research Helper upgrades your research experience on eBay’s built-in product research tool (formerly known as Terapeak).
  
  It restores hidden metrics — and then goes further by unlocking entirely new signals, such as:
  
  📈 Listing Visibility: Detect listing suppression & performance based on demand and visibility counts
  
  📊 Sales by Weekday: See exactly what day of the week buyers are converting and time your listings accordingly
  
  🔁 Sold Over Active: A short-term demand signal derived from sell through rate
  
  📰 Items vs Listings: Breaks down the difference between listing and item volume
  
  
  Metrics can be viewed using the on screen overlay, in the extension's popup, or exported as a JSON file
  
  Optional integration with SellThru backend is supported for deeper research workflows
  
  Whether you're just looking to get back missing sales volume or you're trying to strategize your product research, eBay Research Helper turns eBay’s seller tools into a real advantage.
