What Is AdSense?
Before signing up to AdSense, it’s important to understand what you’re signing up to. Many of the principles and strategies that I describe in this book make the most of the way that AdSense works. If you can understand where AdSense are getting their ads, how they assign those ads to Web pages and how they fix the prices for clicks on those ads or for ad appearances on those pages, you’ll be in a great position to manipulate AdSense in a way that gives you maximum revenues. Unfortunately, I can’t really do that. Much of the way that Google runs the AdSense program is kept under wraps. I know a few things — and enough to do a great deal with our AdSense ads. But I don’t know it all. No one outside Google does. And for good reason. If it was clear how Google figured out the content of each website and which ads suit that site best, there’s a good chance that the Web would be filled with sites created specially to bring in the highest paying ads instead of sites built to bring in and inform users. People do try to build sites for ads not content, but they tend to make less money than high quality sites that attract loyal users who click on ads. The fact is, we can make the most of both AdSense and our own ad space without knowing the algorithms that Google uses to assign ads and pay sites. That’s because AdSense is pretty simple. At the most basic level, AdSense is a service run by Google that places ads on websites. When you sign up to AdSense, you agree to take the ads that Google gives you and receive a fee each time a user clicks on that ad (or for each thousand ad appearances the ad receives on your site, depending on the type of ad). The ads themselves come from another Google service: AdWords. If you want to understand AdSense, you will need to understand AdWords. Advertisers submit their ads to Google using the AdWords program. They write a headline and a short piece of text — and here’s where it gets interesting — they choose how much they want to pay.
