Google AdSense

AdSense is quite popular nowadays, but for those who never heard about it I will explain its mechanics in a few words: AdSense is an ad serving program run by Google. Website owners can enroll in this program to enable text, image and video advertisements on their sites. These ads are administered by Google and generate revenue on either a per-click or per-thousand-impressions basis. My experience with this company so far is positive but there are many people who were falsely accused by Google of click fraud and as a consequence their accounts were closed. I myself run two websites and both of them are generating income.
