The essence of programmatic advertising can be brought down to two phrases: Getting the right value for impressions and appearing in front of the right audience. Header Bidding and Exchange Bidding are here to offer both. Then, who’s the winner – Header Bidding Vs Exchange Bidding?
We’ve come a long way from the days where the publishers and advertisers relied completely on Google to monetize their inventories.
In fact, Header Bidding has its unbeatable place in today’s programmatic advertising not only because it helps publishers and advertisers to trade more optimally, but also it gives them the flexibility, they needed to realize.
Of course, Google and Facebook duopoly can’t be chipped away just by Header Bidding. But, it’s a key hack that will have its place in the adtech. Keeping the future of Header Bidding aside, we’ll try to focus on Header Bidding Vs Exchange Bidding in this piece.
We’ll discuss what they are, how they work, and what are the differences between the two bidding technologies.
Header Bidding Vs Exchange Bidding
Header Bidding or Pre-bidding is an advanced programmatic technique where you can open your inventories to several demand partners, before sending the call to the ad server. So, bidding parameters (from the demand partners) and ad request will be sent down to the ad server.
Why should you do that?
Waterfall Setup of Ad server and
Google AdX Privilege.
Avoiding them yield better revenue and put everyone on the same foot. Need to know more about the ‘Waterfall’ and ‘Google AdX Privilege’ and why you should avoid them? Take a look at this definitive guide.
As a result of header bidding, publishers have seen improved ad revenue without increasing the number of ad units.
As per AdZerk’s latest header bidding report, closed to 80 percent of top 1000 sites that use programmatic to sell ads use ‘Header Bidding’ to monetize their inventories. The adoption rate is graudually increasing for the last few years.
Even though header bidding increases the revenue by up to 60 percent, publishers need to partner with the right companies (SSPs) to get the results.

Exchange Bidding, also known as Google’s Header Bidding is developed by Google to take back its so-called monopoly status. As header bidding proved to be effective for both publishers and advertisers, Google released ‘Exchange Bidding’.
To be frank Exchange Bidding was a counter punch by Google to Header Bidding Vendors.
Exchange Bidding is a server-side unified auction where several Ad Exchanges and SSPs can compete along with Google’s Ad Exchange (AdX) to win the impressions, just like header bidding. Google reportedly dropped its last look advantage in EBDA to make itself more friendly.
The main difference is, the auction will be happening inside DFP (ad server), not on the users’ browser. Here’s how the process looks like:
1. An ad request is triggered and the information is passed to the DFP ad server
2. DFP runs a unified auction to determine the best yield
2a. DFP selects the best-trafficked line item to compete in the unified auction
2b. DFP sends a bid request to targeted yield partners
2c. Targeted yield partners run their own auction and return their most competitive bid to DFP
2d. DFP hosts a unified auction and selects a winner
3. A creative or Mediation list is returned to the publisher
Header Bidding Vs Exchange Bidding – Which One is Right for you?
Both have their own pros and cons. For instance, Header Bidding will be completely transparent and can be managed or customized by publishers. And, with the availability of Open source header bidding technologies like Prebid, it has become much easier to implement and execute header bidding.
On the other hand, Exchange Bidding helps you to deal with Page latency. As we’ve shifted the auction to server-side, the number of ad requests and wait time can be reduced. But, Server takes care of the auction and publishers have no control here. Google doesn’t allow PMPs and decides the buyers who can compete with AdX. Adding to this, adtech vendors are expected to pay a fee or tax to Google for participating. So, its still under question whether publishers and buy-side platforms or Ad Exchanges are going to use Exchange Bidding.
What’s Server-Side Header Bidding?
Server-Side Header Bidding was developed to execute header bidding on the server rather than using browsers. This, in turn, reduces page latency and frees up the limit implied on publishers (In Client-Side Header Bidding, Publisher can add up to 7 or 8 demand partners. If the count exceeds, page latency will be high). However, publishers and advertisers face an issue with the match rates in this technique.
There’s no single method with no drawbacks. It’s up to you to decide and execute the right solution. So far, OpenX is the noticeable one to publicly state that the revenue has been increased while using Exchange Bidding (in Beta). If you’re a mid-range publisher, you need a transparent solution where Exchanges and SSPs can integrate with you for free. After all, we’re talking about a few extra milliseconds load time in header bidding. If you’re a premium publisher, then you can consider implementing it on the Server-Side.
