Prebid.js is the industry-leading open-source header bidding wrapper used by thousands of premium publishers worldwide. By running Prebid.js on your site, you enable multiple SSPs and demand partners to compete simultaneously for each impression in a fair, transparent auction — replacing inefficient waterfall setups with a unified auction that consistently delivers higher CPMs.
The core innovation of Prebid.js is the parallel auction: instead of offering impressions to demand partners one at a time in a predetermined order, Prebid.js sends bid requests to all configured partners simultaneously, waits for responses within a defined timeout window (typically 1-2 seconds), and passes the highest bid to the ad server as the winner. This ensures the advertiser willing to pay the most for each specific impression always wins, regardless of their position in a waterfall hierarchy.
Publishers implementing Prebid.js with Stellor Media's adapter gain access to our full demand stack — 50+ DSPs, trading desks, and direct advertiser relationships — through a single adapter configuration. Our team handles all technical implementation during 48-hour onboarding, including adapter setup, timeout configuration, price granularity settings, and Google Ad Manager line item creation.
How Stellor Media Implements Prebid SSP Integration
Stellor Media maintains an actively maintained Prebid.js bidder adapter that integrates with Prebid.js v7.0+ and all current release versions. Our adapter supports all standard bid formats including display, video (VAST), and native (OpenRTB Native).
The integration process is straightforward: you add the Stellor Media adapter to your Prebid.js build (either through the Prebid.org download tool or the npm package), configure your publisher ID and ad unit settings provided by your account manager, and Stellor's team creates the corresponding Google Ad Manager line items during onboarding.
Post-launch, Stellor's team monitors adapter performance — bid rate, win rate, average CPM — and makes configuration adjustments to optimize revenue. Our adapter is updated with each major Prebid.js release to maintain compatibility and adopt new features like Enhanced Price Buckets, GPT integration, and Prebid Server hybrid configurations.
