Google AdSense is a program that’s run by internet’s most famous giant tech company:
It basically allows publishers that are part of the Google Network of content sites to actually serve automatic text, video, image, and even interactive media advertisements which will then be targeted to the site’s content and to an audience.
These ads can actually generate some sweet revenue on either a per-impression or a per-click basis.
