An ad network is a type of ad technology (ad distribution/optimization technology) and refers to a distribution method that cross-networks several sites and search engines. Ad network is a method used to distribute advertisements by limiting media and networks.
By the way, the mechanism for bidding and purchasing across multiple media and ad networks (ad space transactions) is called an ad exchange. While ad networks bid on the entire distribution network, ad exchanges bid on specific ad space.
Advantages and disadvantages of ad networks
The advantage of ad networks is that they are easy to operate with a certain amount of experience and knowledge, as they manage specific distribution frames and networks, including ad exchanges.
On the other hand, the disadvantage of ad networks is that you cannot choose the advertising medium, so your ad may be posted on a site that is not your target. Also, each ad network has different bidding methods, billing methods, and
targeting
settings, so you need to adapt your operations to each ad network.
Also, be aware that ad networks often charge on a pay-per-click (per-click) basis, rather than CPM (per-impression).
