CRO for Marketplace Platforms: Optimize Both Sides of the Market

Marketplace CRO is uniquely complex: you’re optimizing for two audiences simultaneously — buyers and sellers. This guide covers tactics for both sides.


Marketplace Benchmarks

  • Buyer CVR (browse to purchase): 2—5%
  • Seller signup to first listing: 30—50%
  • Search to click: 15—30%
  • Listing view to purchase: 3—8%
  • Repeat buyer rate: 40—60%
