It can be confusing for beginners to grasp the difference between Google Adwords and Google Adsense. They are in fact two separate programs, although they work in tandem with each other to deliver results for all parties involved. Google Adwords is the program that allows advertisers to advertise their website by the use of ads.

They can also be displayed on Google's partner sites like other search engines or on publisher/webmaster's websites. Get all the info you need here.
