taggit Summary
In addition to displaying advertising on their own platforms, such as Google’s search engine and Facebook’s home page, websites, app developers and publishers rely on the companies to secure advertising for their pages. In the milliseconds between a user clicking on a link to a web page and the page’s ads loading, bids for available ad space are placed behind the scenes in marketplaces known as exchanges, with the winning bid passed to an ad server. Seeing a potentially significant loss of business to header bidding, Google developed an alternative called Open Bidding, which supported an alliance of exchanges. While Open Bidding allows other exchanges to simultaneously compete alongside Google, the search company extracts a fee for every winning bid, and competitors say there is less transparency for publishers.
