Google AdSense is a free advertising program that allows online content publishers to make some decent and easy money with their web platforms. It is the other side of Googles’ AdWords program where companies and businesses bid on keywords to receive targeted traffic to their own web platforms.
The AdSense publisher simply puts a piece of code in the websites’ files. This code displays the ads in the AdWords network on the publisher’s website. Google will automatically place relevant ads that might appeal to the websites’ users. Then when someone so much as clicks on one of those ads you (the publisher) get paid!
It really is that easy! Applying for AdSense is free and you can be approved in as little as a week.
