Prebid

How do Adhese and prebid work together

When a publisher implements Adhese through Prebid, they're participating in a header bidding auction where multiple demand partners (including Adhese) compete to deliver ads. Here's how the process works:

Auction Initiation

When a page loads, Prebid sends simultaneous bid requests to multiple bidders - including Adhese - rather than sequential requests. This concurrent approach is one of Prebid's key features for managing latency. All bidders (including Adhese) receive their request at roughly the same time.

Adhese's Role in the Auction

Adhese acts as a bidder/SSP within Prebid's ecosystem. Through the Prebid adapter, Adhese receives ad requests and returns competitive bids and creatives. The adapter translates Prebid's standardized request format into Adhese's API requirements and vice versa.

Bid Submission & Timeout Management

Publishers set a timeout value (typically 1-3 seconds) that determines how long Prebid waits for responses. Adhese must return its bid within this window. If Adhese doesn't respond in time, Prebid excludes it from that auction round. This timeout mechanism prevents slow bidders from degrading page performance.

Ad Selection

After all bidders respond, Prebid passes the winning bid to the publisher's ad server. If Adhese wins, its creative is selected and delivered, leading to an impression in Adhese.

Targeting & Parameters

Both Prebid and Adhese support custom targeting. Publishers can pass first-party data (like content categories, user segments, or location) through both systems, giving Adhese context for more accurate bidding.

Impression Tracking

After an ad is selected and rendered, Adhese can track impressions and viewability through Prebid's event system, feeding performance data back to their platform.
