Google AdSense
If you are interested in making money online you should definitely check out 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 even video advertisements on their sites. These ads are managed by Google, and generate revenue on either a per-click, or per-thousand-impressions basis. My experience with this company so far is positive; however, there are many people who were falsely accused by Google of click fraud, and because of that their accounts were closed. I know webmasters who have various websites, and all of them generate income because of implementing AdSense. Integrating AdSense on your websites is an especially good idea if you receive a lot of traffic. You will not make a lot of money with this program if you have only a few visitors. Another thing to consider that there are limited payment options and it is impossible to be paid by PayPal. This means that while AdSense might be a good choice for some webmasters, it is definitely not a program for everyone.
