The 10 Best Header Bidding Network Partners (2021 Update)

Header bidding has no doubt become the choice option for publishers looking to scale their ad earnings. Beyond putting more money in your wallet, the process provides complete transparency and more ad control–which is a big win for publishers!

The advanced programmatic technique works by bringing various ad networks to bid in real-time for ad units simultaneously. By opening up inventory to various demand sources, competition is increased, and with it, revenue. To truly get access to premium rates, you’ll want to be sure to have top header bidding network partners in your wrapper.

Benefits of Header Bidding 

More demand sources: Header bidding providers give you a wide supply of buyers in terms of quality and diversity. The increase in competition will lead to an increase in yield. Similarly, access to diverse partners will improve the ads being served to your visitors.

Easy to manage: With a header bidding wrapper, it becomes easy to manage and organize the bidding process. You can do things such as add or remove demand partners. The header bidding wrapper is a piece of code that resides on the publisher’s webpage. This piece of code communicates with demand partners and sets the rules for the running auction. 

Transparency: Publishers can keep track of the transaction data for each impression, making it easier for publishers to confirm that an impression has been sold.

Greater fill rate: A greater number of advertisers participating in the bidding process improves fill rate. The bidding process is optimized when comparing bids from all the demand partners.

Essential Information

Requires technical expertise: From creating the header bidding code to implementing it properly on your website, a fair amount of technical knowledge is required to ensure a seamless set-up. When done incorrectly, user experience and revenue suffer.

It’s important to work with a team of professionals who can correctly implement on the fixings your website needs.

Requires a quality header bidding provider: Working with a low-quality header bidding provider can go just as wrong as attempting it yourself. For starters, low-quality providers work with low-quality header bidding ad networks. Which, for you, means not seeing that increase in yield we previously talked about. You could also experience issues with page latency, unfilled ad units, and poor user experience.

A quality provider will have premium demand partners and solutions for the common troubles that come with advertising. They’ll be able to add timeout settings for page latency problems, optimize ads for user experience, and so much more.

All things considered, header bidding provides the publisher with control over ad inventories and increases in ad inventory revenue. With those considered, it’s safe to say header bidding is here to stay.
