Estimated digital ad spend sits at $455 billion in 2021. Over 55% of that will be allocated to display ads, emphasizing the importance of a capable ad server.

With so many available ad servers on the market, finding the perfect one can be a difficult task. We rank Google Ad Manager, Kevel, and Smart as the three best options available to publishers. They have a broad range of features and advertising products to separate them from the competition.

Ad servers give publishers access to better ad inventory, more accurate audience targeting, and advanced analytics features, unlike other alternatives.

Ad servers provide solutions for both advertisers and publishers to improve their monetization techniques and increase revenues. We have analyzed the eight best ad servers for publishers based on available features, reporting, analytics, and other relevant tools for the most optimized ad delivery.

Here are your top ad servers for publishers:

Google Ad Manager

One of the best ad servers for publishers is Google Ad Manager, although previously known as Double Click. After a purchase in 2008, Google rebranded Double Click to Google Ad Manager to provide customers with a versatile ad server.

Google Ad Manager is convenient because it easily integrates with Google Adsense to offer more revenue potential for publishers. There is no need to link to a third-party server if you rely heavily on Adsense already.

All ads are automatically re-scanned intermittently to allow for a smoother delivery process. There is also a way that the Google Ad Manager server creates dynamic allocation and price combinations for ad delivery. Both features are extremely impressive to show the right ads at the best times while keeping prices optimized.

The security provided by the Google Ad Manager is also exceptional. There are malware detection functions that identify any suspicious threats like fake URLs or viruses.

Google Ad Manager is a demand-side platform that gives digital advertising buyers the opportunity to manage more than one ad exchange in the same place.  


  • Wide range of key metrics that can be tracked.
  • Niche audience access and targeting.

What is an Ad Server?

An Ad Server is an advertising technology that gives publishers and advertisers the access to manage the way they run their online advertising campaigns. Ad servers are unique in the way they run ads because the decision to display a specific ad is made based on the data collected by the server.

The ad server will monitor ad performance by compiling data like clicks, impressions, and reach. These are critical metrics that advertisers use to monitor the quality and performance of their advertisements.

There are two types of ad servers: First-party and Third-party. Both of these technologies can track, monitor, and manage ad campaigns. They also provide a medium to both buy and sell ads directly or through other ad platforms. These processes are known as direct deals or real-time bidding.

Why Do You Need an Ad Server?

Publishers need an ad server because they can use fresh and up-to-date content on their website seamlessly. The content is also highly targeted based on audience data collected by your ad server provider.

Ad servers do many different things to optimize the way content is published and displayed on your website. You are given access to an inventory of ads with full campaign management control and performance tracking capabilities.

Ad servers use real-time bidding so you can auction off ad space for advertisers to compete over. Doing this process without a complex ad server is extremely difficult and performance tracking is impossible.

The full range of features you can get from any of the ad servers we discussed include ad performance tracking, ad refreshing, frequency controls, ad optimization, and full reporting capabilities.  

How Do Ad Servers Work?

Ad servers are broken into two separate categories based on the way they operate. There are first-party and third-party ad servers to serve the different needs of publishers.

The entire process of an ad server starts with a user opening their web browser and navigating to a specific page or application. Once the user arrives at the page, it will trigger an ad request based on the specific criteria this user meets based on collected data. Examples of data include location, age, or interests.

After the data is analyzed, the ad server uses intelligence to deliver a relevant ad in a specific location on the web page to gain the attention of the user. Once displayed, the user has the ability to click on the ad if they are interested enough. This would lead them to a conversion page developed by the advertiser.

The ad server would then track this data and give advertisers and publishers the ability to view ad performance. Metrics tracked include impressions, clicks, conversions, and more.  

First-Party Ad Server

A first-party ad server is hosted online by a publisher with the intention to serve advertisers’ ads on their own websites or apps. This is the most straightforward way to deliver ads and makes the process of selling ad spots much simpler.

If there are no direct ads being bought, this ad server also has the ability to pull ads from partner ad networks or servers to display them as inventory.

Third-Party Ad Server

A third-party ad server is more used by advertisers or agencies to store and manage their advertising code in one place. This makes it easier to track, deliver, and analyze all ad campaigns that are being one in a single platform.

Advertisers have better access to verify ads this way and avoid potential fraud. The A/B testing features available on third-party servers are much more effective too.  

Hosted vs Self-Hosted Ad Servers

Ad servers are further defined by their hosting method. Platforms are typically defined as either a hosted or self-hosted server. Publishers have unique needs that differ from advertisers, so understanding how both of these options work is essential in deciding on the right ad server for you.


A hosted ad server is run by a third-party ad server company. This means you don’t need to possess the intense technical knowledge to run it on your own and you can leave the difficult aspects to another company. There is no installation required and technical support is intensive to keep things running smoothly.


  • No installation required.
  • Easy to use, especially for beginners with no technical background.
  • Automatic updates.
  • Better high-speed performance.


  • More expensive.
  • Less ad customization options.
  • Data controlled by a third party.  


Self-hosted ad servers are hosted on a client’s own online server where they have complete control over everything that happens. Running a self-hosted ad server requires technical knowledge with a team to handle data storage, updates, technical issues, and installations. If you have the team to manage the server, this is obviously the better option.  


  • Cheaper upfront costs.
  • More customization options for ad delivery.
  • More secure with all data stored under your own control.


  • The installation process can be complex.
  • Technical issues require expertise to fix.
  • Updates must be done manually.

What is an Open Source Ad Server?

Open Source ad servers are free ad server systems that give publishers more power when controlling or managing their ads. For example, they give access to serve ads on different platforms while collecting important data like conversions.

The Open Source system can handle multiple advertisers running their campaigns on the same network as a third-party server would do. The biggest difference between this ad server and a third-party ad server is the cost, as Open Source is completely free.

However, the Open Source system benefits advertisers more than it does publishers. Advertisers are given better access for free while publishers require different features and cannot take advantage of this benefit.  

Verdict: What’s the Best Ad Server For Publishers?

The best ad server for publishers depends entirely on what you value most. If you prefer a free option with extensive network access and easy configurations, the Google Ad Manager is an excellent choice to consider.

If you are looking for something more complex with more variety in APIs, Kevel is a good choice. They provide publishers with more access to content and ad delivery types making it easier to implement native content.

As a publisher, you should aim to find the ad server with the most advanced controls to manage ad elements like inventory, format, targeting, and optimization tools. Both Kevel and Smart can check the boxes here and give you plenty of tracking capabilities too.
