Each good information begins with a definition, so let’s begin this one by defining in-app bidding.
In-app bidding is a programmatic promoting mannequin that features two sides: app publishers and advertisers.
In it, app publishers promote their advert stock in a unified public sale, and advertisers bid towards one another in real-time.
From the writer’s perspective, what makes this mannequin particular is that they’ll supply stock to all demand sources without delay.
From the advertisers’ perspective, they get a good probability to compete on advert stock on the similar time. With another strategies, they’d solely acquire entry to a restricted proportion of stock.
The Historical past of In-App Bidding
In case you actually need to perceive in-app bidding, it is advisable to perceive its origins.
You’ve most likely heard concerning the time period “in-app header bidding”.
If that is so, you’re most likely questioning – what’s the distinction between this time period and in-app bidding?
There isn’t any distinction.
It’s only a matter of wording and, properly, historical past.
Header Bidding on Desktop
The phrase “in-app header bidding” comes from the preliminary thought behind in-app bidding.
The factor is, earlier than this kind of bidding got here to the world of cellular, a comparable mannequin existed on the net.
On desktops, header bidding got here to life in 2015. As quickly because it appeared, it rocked the present desktop promoting world.
The factor is, on the time, advertisers bought bored with waterfall bidding and Google’s public sale guidelines. Because of this, they began on the lookout for options.
Nevertheless, header bidding turned out to be rather more than simply an alternate.
Right here’s the way it works.
On this mannequin, the online publishers public sale stock of their net web page headers in real-time.
For this goal, they add a wrapper to their web sites’ headers.
This permits advertisers to concurrently compete for a spot at a header of an internet web page. Whoever wins the public sale, their code will get integrated into the header.
On account of this methodology, publishers began getting the very best doable worth for every impression. The truth is, in response to Fyber, due to this mannequin, net publishers have seen as much as 40% increased eCPMs.
Alternatively, the profit for advertisers was fairly apparent – they bought to the highest of the web page.
In-App Header Bidding
Whereas all this was taking place on the net, the app world caught with the “good outdated” waterfall bidding mannequin.
Nonetheless, app publishers and advertisers additionally began craving one thing like header bidding.
The issue? There are no headers in cellular apps.
Because of this, it was more difficult to develop options for-in app header bidding. Fortunately, within the final couple of years, totally practical in-app bidding options appeared.
As a substitute of counting on headers, in-app header bidding works with an SDK integration that generates advert requests for an app.
The advert requests take part in an public sale within the cloud with server-side demand companions. As soon as there’s a successful bid, the in-app bidding platform sends out a response to the consumer SDK.
As you possibly can see, this course of is all the things however easy. No marvel it was so tough to develop.
In-App Bidding vs. Waterfall Bidding
There isn’t any speaking about in-app bidding with out speaking about waterfall bidding.
We will have a look at it as a new vs. conventional relationship.
On this relationship, waterfall bidding is the older, conventional approach, whereas in-app bidding is new and improved.
The waterfall mannequin has been the customary of advert monetization for the previous decade.
Basically, waterfall bidding works similar to water flowing down a cliff.
Within the waterfall, the advert server calls advert networks in a predetermined order, one after the other. This order relies on historic costs and efficiency. There’s additionally a worth ground – the minimal worth that can be accepted for the location.
Then, the requests for bids go down the “cliff” of bidders till certainly one of them meets the worth ground.
On this course of, it’s not vital how a lot the advertisers are prepared to pay for an impression. As a substitute, historic knowledge has a bonus. In consequence, the mediation platform will give a bonus to the advert networks it has beforehand labored with.
Sounds form of unfair?
That’s precisely what publishers and advertisers don’t like about it.
Within the waterfall mannequin, publishers are doubtlessly leaving cash on the desk. The factor is, they’re counting on the mercy of the primary bidder in line to bid for advert house. Even when somebody on the backside of the listing would bid extra, the writer by no means will get to search out this out.
A whole lot of advertisers discover this mannequin discriminatory. The way in which the waterfall works, not everybody will get a good shot to compete for advert house.
Improved (In-App Bidding)
In-app bidding was created to resolve the problems surrounding waterfall bidding.
This bidding mannequin permits publishers to supply stock to all potential bidders. This additionally contains those that wouldn’t rank excessive within the waterfall.
Whereas the waterfall mannequin prioritizes the primary bidder, in-app bidding provides the benefit to the very best bidder.
Right here, historic knowledge is totally irrelevant.
Within the in-app bidding mannequin, it’s vital what occurs in real-time, not what occurred earlier than. To make this occur, it really works on the idea of a unified public sale.
Within the unified public sale, a number of demand sources acquire entry to the identical advert stock. They bid for it in real-time, and the upper bidder wins. This manner, the costs can go up fairly a bit, leading to increased eCPMs for publishers.
A real unified public sale ought to have these three traits:
- Being inclusive for all demand sources
- Concurrently distributing advert requests
- Permitting everybody to bid in real-time
At coronary heart, unified auctions aren’t a lot totally different from real-life auctions.
Think about a bunch of millionaires auctioning for one thing in a crowded room. On this case, no one cares if somebody is a brand new, self-made millionaire or they arrive from an “outdated cash” household.
Whoever bids most in the intervening time wins the public sale, and that’s all of the knowledge to it.
In-App Bidding + Waterfall Bidding
Regardless of their variations, there doesn’t must be a versus on this relationship.
In-app bidding and waterfall bidding can work hand in hand. This combine is known as a hybrid setup, and it’s prevalent amongst app and sport publishers. In keeping with Enterprise of Apps, hybrid setups are dominating the market in 2021.

- The advert mediation community shortly runs a verify of advert networks within the waterfall mannequin to see if there’s a higher supply (increased eCPM).
- If there isn’t any increased bid, the winner advert runs immediately.
- If the waterfall accommodates a increased bid, this advert will run first.
Sounds nice, proper?
This sort of resolution permits publishers to get one of the best out of each worlds. With this setup, they need to obtain the very best revenues no matter the place the successful advert comes from.
