Google AdSense is a program run by Google Inc. that allows publishers in the Google Network of content sites to serve automatic text, image, video, and rich media adverts that are targeted to site content and audience. These adverts are administered, sorted, and maintained by Google, and they can generate revenue on either a per-click or per-impression basis.
Google AdSense is the best advertising program for the website owners. Here is no substitute for Google AdSense because, it gives highest CTR rate comparing all other advertising campaigns.
Today I’ve noticed nice update from google adsense, Text changed from “Ads by Google” to “Related Ads” for text link Ads.
