What is an Ad Server ?
An ad server is a form of advertising technology used by advertisers and publishers to serve ads to potential customers. It’s a web server that stores information on different ads, and shows them to visitors according to targeting inputs. Ad server platform also tracks data such as impressions and clicks which ad server companies or advertisers can use to monitor their ad performance and optimize campaigns. These ad server platforms allow advertisers and publishers to manage ad campaigns in all digital formats.
The first ad server was introduced in 1995, and the technology is still used today as it allows publishers to serve ads customized and personalized for different segments, as well as change media types (e.g. text, gif, video). Ad server software is the technological engine that enables advertisers and publishers to optimize, manage, and distribute advertisements across a wide range of paid channels. A hosted ad server is an ad server software platform that is maintained or sold by an advertising network company.
There are two types of ad servers today: first-party ad servers and third-party ad servers. A publisher would use a first-party ad server to manage their ad inventory and display ads on their websites. A first-party ad server is also responsible for targeting and collecting data. On the other hand, an advertiser would use third-party top ad servers to collect ad data, verify information received from the publisher, and change the ad creative.
