The King of Display: Google AdSense
Google’s AdSense is one of the largest and perhaps the best known display advertising network. This platform allows publishers to monetize standard display ads, mobile and video, and search results as well.
It’s free to sign up for AdSense and the program will accept the smallest of publishers provided they meet certain quality guidelines. AdSense also integrates smoothly into other Google products (such as DFP) and generally pays publishers monthly for revenue generated the previous month.
