Users interact with the third party ad server each time they load pretty much every web page. Website owners show a variety of ads depending on the advertisers' targeting criteria — geo, age, behavior etc. Precise targeting helps advertisers show the user only relevant ads that he would click on.

Publishers are managing hundreds of advertisers at a time: to keep them all in one place they'd have to build an ad serving technology to determine which ads to show, where to place them, how often will they be shown, and who will see them. Advertisers, on the other hand, will need to come up with a system to track the ad campaign performance, optimize it and control the ad spend.

It's a lot of work, right? And that's why they often outsource it to the third-party ad server.

What is a third-party ad server?

The definition, in short, would be:

A third party ad server is a web server which hosts data regarding ads and delivers ads directly to websites and mobile apps. Besides hosting — serving ads, third-party ad servers enable you to manage and optimize online advertising activity.

A third party ad server is a B2B service which delivers ads directly to websites and allows website owners to best capitalize their ad inventory. Third-party ad serving core customers are publishers, media agencies and advertisers. The customers pay to have access to be able to log into the third party ad serving interface. Once inside the interface, the functionality is broken down into two separate areas: campaign management and ad reporting.

Customers choose a third-party ad server for these main reasons:

  1. To simplify the ad serving process & to keep all the demand partners in one place.
  2. To avoid any discrepancy.
  3. To get a reliable solution for ad serving.
  4. To run cross-platform, complex ad campaigns, and use multiple ad formats.
  5. To get real-time analytics on ad campaign performance.

How does the third-party ad server work?

The ad serving process is done within seconds without the user noticing it. Here is how the ad server works:

  1. User visits your website or app.
  2. At this very moment, ad tags are requested from the third-party ad server. The ad tag includes a list of criteria on which ads are suitable. The criteria is formed by advertisers, who choose geo, age, behavior, the size of the ad slot, and much more.
  3. The third-party ad server chooses which ads to serve based on the pre-defined criteria.
  4. The selected ads are delivered directly to the website or app to be shown to the user.
  5. The third-party ad server tracks impressions, clicks, conversions, and other essential metrics & stores the stats on a single platform.

Sounds easy, right? But imagine this process is being done with hundreds of ad campaigns simultaneously.
