As B2B buyers evolve, so does their buying process. Learn how B2B marketers can evaluate and refresh their strategies to meet changing needs.
Ask a Centro Expert is a blog series from Centro where we break down the complicated tools, tech, and trends you've been hearing about in the trade pubs and around the office. We reach out to some of our in-house experts to ask the tough questions and turn them into bite-sized, palatable Q&As for your reading pleasure. Last month, we explored ad blocking. This month's topic: Header bidding. We talked to Jessica Burget, Centro's Director of Partner Development, for the break down.
Header bidding is the technology that allows a publisher to have multiple demand partners compete to buy their inventory at the same time – and the best demand partner wins.
How is it different than how publishers traditionally manage their inventory?
Before header bidding, a publisher had to set-up a “waterfall" within their ad server, leaving the publishers to constantly evaluate which SSP/exchange partner to prioritize over the next – without actually knowing what their inventory was worth.
If publishers implement header bidding technology, they can work with more demand partners, increase revenue, and have insight and data into the value of their inventory.
At first, I think people and companies felt that header bidding was a passing trend or a fad that wouldn't last, but over the last few years, adoption has been tremendous on the publisher and SSP side.
In my opinion, if an SSP or publisher is not supporting header bidding, they are behind the industry and their competitors, and they are missing out on revenue opportunities.
Currently, there are two types of header bidding: wrapper solution or server-to-server (S2S).
A wrapper solution requires placing a piece of code on a website, which allows the demand partners to bid on the inventory before the page even loads.
On the flip side, S2S technology is not within the browser, and it's when a publisher utilizes an external server solution. For implementation, a publisher and SSP will need to research the header bidding market to find the best fit for their business. After a company has vetted different partners in the space and made a decision, tech and implementation teams should be looped in to collaborate with the vendor.
To narrow down the header bidding vendor short list, here's my advice:
If an advertiser/DSP is working with any major SSP in today's digital world, then they are accessing header bidding inventory.
For an SSP to be a demand partner, work with the publisher to see which vendor they utilize. If both the SSP and publisher is integrated with the header bidding vendor, then come to an agreement to be a demand partner and begin the set-up process.
Header bidding allows a publisher to have access to more demand partners, increased revenue with higher valued inventory, and more accurate data on who is actually a good demand partner.
For advertisers buying programmatically, they now have the ability to compete directly with direct-sold campaigns.
From a publisher perspective: The downsides are scarce. From a business standpoint, it can be expensive and timely to implement a header bidding solution. From a technical standpoint, if a publisher chooses to utilize a wrapper solution, then they run the risk of page latency. If they go down the S2S route, cookie matching can be a challenge and they also need to make sure the S2S vendor isn't favoring their own demand over others.
From an advertiser/DSP perspective: The downsides are higher. Since everyone is on a level playing field, rates will increase across the board. Also, if a DSP is integrated with multiple SSPs that now have access to all of the same inventory, the cost of supporting multiple SSPs is now wasteful. I assume advertisers/DSPs will have to do more work evaluating who they chose to partner with over the next year or so.
Here are five things I predict we will see:
