The programmatic advertising world is moving super fast, and publishers are always hunting for smarter ways to make money without annoying their users. Two big tools are shaking things up: Google Ad Manager’s Server Side Unwrapping (SSU) and Prebid’s open-source header bidding. Think of them like secret weapons in a game—each with its own powers. If you want to crush it in ad revenue, you’ve got to know how they differ, what makes them awesome, and how to actually use them. It’s like knowing which cheat code actually works before you hit “play.”
Understanding the Fundamentals
What is Google Ad Manager Server Side Unwrapping (SSU)?
Think of SSU like a backstage pass for video ads. Instead of your device doing all the heavy lifting, Google’s servers handle the messy stuff, following ad chains and fixing glitches. This means way fewer errors—like 83% fewer—and super smooth playback, which is a lifesaver for Connected TV and video ads. Imagine trying to stream a show and the ad keeps freezing—SSU is the hero that stops that nightmare.
What is Prebid?
Prebid is like the ultimate open-source toolkit for getting the best ad deals on the web. Its brain, Prebid.js, connects to over 300 ad buyers and dozens of analytics tools. And just like SSU, it has a server-side version too, running auctions behind the scenes to cut down waiting time. Whether it’s mobile apps, AMP pages, CTV, or even digital billboards, Prebid helps publishers squeeze every drop of value from their ad space. It’s like having a super-smart robot that finds the best deals for you, 24/7.
Technical Architecture Comparison
Server-Side Processing Advantages
Both SSU and Prebid Server move the heavy lifting off your device and onto servers, solving headaches that old-school client-side setups caused. With server-side header bidding, publishers can work with more ad partners without slowing down their pages. Think of it like having a super-efficient assistant doing all the boring math so you can actually play the game.
SSU Architecture:
- Handles VAST redirects on Google’s servers
- Built for video and CTV ads
- Cuts down work on the user’s device
Prebid Server Architecture:
- Open-source and works with any ad server
- Runs auctions server-side
- Keeps the bidding process transparent
Performance Implications
Server-side processing tackles the big pain points:
- Latency Reduction: Fewer back-and-forths mean less buffering—your videos play smooth, no rage-quits.
- Page Load Optimization: Pages load faster because heavy scripts aren’t clogging the browser, giving better Core Web Vitals scores.
Implementation and Integration
SSU Implementation Considerations
Google Ad Manager’s SSU is like adding a turbocharger to a car you already own—it slides right into your existing setup with barely any extra work.

SSU Demand Access
SSU plays really well with Google’s own playground—think Google AdX and all the other programmatic partners in the Google universe.
