Google, one of the biggest internet giants since its invention, subsists entirely on ad revenue. Google gives businesses a chance to be involved in its success through its Google Adwords tool. Though the process of creating and using an Adwords account is generally pretty simple, there are some intricacies which advertisers often don’t quite grasp. As a result, advertisers using Adwords often find themselves neither losing nor gaining any revenue. This video, narrated by Google’s chief economist Hal Varian, explains how to truly take advantage of Google Adwords’s enormous potential to create much more visibility for your website. At the very least, it’ll convince you that Google keeps to their motto, and truly is not evil. Check it out.
