Best Publisher Ad Networks for 2021



Click here to see our CEO and leading industry ad optimization expert, Kean Graham’s tips are for publisher success in 2021.

1. Google Doubleclick Ad Exchange


Despite the continued adoption of Header Bidding, Google’s Ad Exchange network remains the best demand source for publishers in 2021. It serves as the premium version of AdSense and includes many noteworthy features such as:

  • Preferred deals
  • Account-level filtering and blocking
  • Customizable reports based on publishers parameters
  • The ability to set your inventories as branded, semi-transparent and anonymous
  • The ability to block vendors
  • Dynamic Allocation in DFP and DFP Small Business
  • And more…

After Google’s Advertising Product Suite rebranding in 2018, Ad Exchange is now available in the Google Ad Manager.

Keep in mind that if you’re a modest publisher (not generating millions of visitors per month), the reality is that you’re less likely to get an Ad Exchange account.

Don’t worry, though, since we are a certified Google partner; you can sign up to Ad Exchange with MonetizeMore to get access to this premium, top ad network, special features, and most of all, the potential for higher CPMs.

Other online advertising networks worth mentioning

Although this post should only include MonetizeMore’s 10+ best ad networks for publishers, we wanted to quickly mention a few more ad providers that didn’t quite make the cut. These networks are still worth testing in 2021 because of the value that they brought to our publishers in previous years.

These advertising networks include:

Tips from MonetizeMore’s CEO, Kean Graham, for publisher success: What’s your programmatic revenue strategy for 2021?

Kean Graham

There’s no doubt that 2018 was a big year for publishers. Header bidding continued to be a critical revenue factor, and ad blocking remained an issue. Many publishers had to prepare for GDPR, Facebook changed their traffic algorithms, and much more.

However, 2018 is over, and like most things in business and life, it’s best to look forward instead of dwelling in the past. Whatever type of results you experienced in your publisher’s business during 2018, whether good, bad, or mediocre, it’s best to learn from them and move on.

That’s is why we’ve updated and improved our list of top ad networks once again – to help you realize your dream of publisher success.

As you already know, your ad revenue strategy in 2021 can make or break you. Remember to test new display ad networks, implement ad optimization techniques, and try out new partnerships.

What is an ad network in display advertising?

An ad network connects publishers and advertisers (Via demand side platforms). Publishers join an ad network to monetize their traffic with display ads, and other ad types and advertisers access ad impressions to advertise their products and services.

What do ad networks do?

Ad networks connect publishers’ unsold ad inventory with advertisers or buyers and usually take a cut of the ad revenue. The ad network then helps the advertiser to target the correct audience on the publisher’s site.

Why are ad networks needed?

Ad networks simplify the process of ad monetization for publishers. Without ad networks, publishers would have to rely on direct sales to monetize their traffic with display ads. It makes it very easy for publishers to access a pool of advertisers looking to advertise products and services. They act as a marketplace and provides the opportunity to scale ad operations for both advertisers and publishers.

Is Google an ad network?

No, Google is a multi-faceted company that owns and operates many businesses. Google owns an ad network called Google AdSense and DoubleClick Ad Exchange. However, those are better known as ad exchanges.

Who are publishers in online advertising?

A publisher is either a business or individual which owns and operates a range of website platforms, apps, and social media accounts. Through these platforms, publishers generate traffic, build an audience, and then market various products and services to their audiences to monetize their content. They can monetize their content/platforms through display advertising, eCommerce, affiliate marketing, and more.

Which is the best ad network for publishers?

It is difficult to say which ad network is the best for a publisher as each publisher's situation is different. Publishers have traffic from different geographical locations, verticals, user devices with varying levels of traffic quality. Some of the best ad networks we recommend include Doubleclick Ad Exchange, TripleLift, AppNexus, Index Exchange, Rubicon Project, OpenX, Facebook Audience Network, Amazon Publisher Services. It's best to test different ad networks as well. Be sure to check the review of each network here to find networks that best suit your needs.

Which ad network pays the most?

Which ad network pays the most depends on a variety of factors, such as your vertical, traffic geolocation, traffic levels, and various other factors. What earns the most for one site isn’t necessarily the same for another. It’s best to test multiple ad networks to find out which pays the most for your site.

Can I use multiple ad networks?

Yes, you can run multiple ad networks. We recommend that you test different networks to determine which delivers the best RPM rates. When running header bidding, multiple ad networks ensure that auction competition increases. As a result, publishers earn higher ad revenue from their ads.

    This is well-reviewed list of Ad networks. First of all the above listed A Networks are great for Publishers and for Publishers to make the most out of them, they may have to maximize all the available resources offered by the Adnetwork.
