Ep 5: Client-side vs server-side header bidding

Client-side, Prebid.js runs the auction in the browser and calls each bidder from there. Server-side, Prebid Server calls the bidders, so the page does less work and has room for more of them. The catch: server-side bidders see fewer of their own cookies, so they can bid less often or lower. Hence most server-side setups are hybrid.

Your to-do: test client vs server on your own pages. Keep what earns more and loads faster.

Which way does your setup lean?
