5+ Best Ad Servers in 2024

What is an Ad Server?

Simply explained, an ad server is what actually places advertising online where users would see them. It is a component of advertising technology that holds a crucial place in the chain of production for digital advertising.

Ad servers feature sophisticated engines built to make rapid, complex decisions about where to transmit ads. They work in real-time to place an ad inside or near content as the user interacts with it. Ad targeting data and programmatic auction results are supplied to decision engines to impact their judgments.

Ad servers connect publishers and agencies. Using complex decision engines and essential ad targeting information, they store advertising and “feed” them to publishers’ ad inventory spaces.

Ad servers must have settings that control every component of an ad impression, they must store all ad creatives and ad unit information, and they must have powerful decision engines that determine the best ad placement depending on publisher and advertiser demands.

The ad that the ad server eventually shows is informed by information from an ad network about the user. Finally, ad servers collect and deliver critical analytics from ad networks, such as ad impressions, to advertisers and publishers.

Types of Ad Servers:

Ad server platforms are roughly classified into two types:

  • First party Ad Servers
  • Third Party Ad Servers

First Party Ad Servers:

Publishers have considerable control over their inventory thanks to first party servers, which enable them to effectively plan ad placements, enhance ad delivery, and access statistics.

First party ad servers are specially hosted on a publisher’s server and send ad requests to advertisers to show them on the publisher’s website(s) or mobile app(s). This streamlines and simplifies the process of selling and buying ad slots.

The first party ad server chooses which ads to display on a publisher’s inventory in modern times when direct ad campaigns (sold directly to the publisher) are not being run.

Third Party Ad Servers:

On the other hand, marketers and ad agencies utilize third-party ad servers to store and manage advertising code as well as to deliver, track, and evaluate ad campaigns that are running on different publishers’ websites.

Third-party servers allow advertisers to effortlessly deploy their creatives and maintain their campaign-wide optimization. These ad servers also provide data administration, reporting, and overall campaign optimization.
