How Marketplaces Are Building Their Own Search Engines

Episode 51 of The Platform Economy with Fexingo examines why major marketplaces are investing in proprietary search technology instead of relying on Google or Bing. Lucas and Luna break down the economics of vertical search, using the example of Etsy's 2023 acquisition of the machine-learning search startup Blackbird Technologies for $45 million. They explore how marketplace-specific search improves conversion rates by factoring in seller quality, return policies, and niche inventory — metrics general-purpose search engines ignore. The episode also touches on Airbnb's search redesign in 2024 that boosted booking conversion by 12 percent, and how Amazon's A9 search engine gives it an estimated $8 billion annual advantage in ad revenue. The hosts discuss the technical challenges, the trade-off between relevance and discoverability, and the strategic moat that custom search builds. A must-listen for platform operators, product managers, and anyone interested in the hidden infrastructure of the internet economy. #MarketplaceSearch #VerticalSearch #Etsy #Amazon #Airbnb #BlackbirdTechnologies #SearchEngine #ConversionOptimization #PlatformEconomics #Business #Technology #FexingoBusiness #BusinessPodcast #ThePlatformEconomy #SearchTechnology #AI #MachineLearning #ProductManagement Keep every episode free: buymeacoffee.com/fexingo
