So how does AdSense figure out how to do all this targeted advertising? Well, AdSense has the ability to deliver relevant ads because the gurus at Google understand how web pages really work and theyre continually refining their technology to make it smarter all the time.
For example, some words can have several different meanings depending on context. Youve seen th is happen with two and too and to. Google technology is smart enough to understand these distinctions from the context that the word appears in, so you get more targeted ads.
When you put a Google search box on your site you start making money off of web searches that people do on your site. This ability to search off of your page keeps them on your site longersince they can search from right there where they areand it will only take you a few minutes to get AdSense up and running. The best part, of course, is that AdSense is free for you to use.
