In three words, earn you money.  More relevant ads on your pages translates into more clicks—and more money that you receive. Because when users click on an ad, Google will pay you. If you’ve set up your own sales team, you’ll get an additional benefit: AdSense complements their efforts.  It doesn’t compete with them.  With AdSense, you get a reporting page that gives you a breakdown on how your ads are doing and what they’re bringing in.

Google has a huge advertiser base, so they have ads for all kinds of businesses and for just about every type of content no matter how broad or specialized it is. And since Google provides the ads, you don’t have to spend time talking to your advertisers.

AdSense represents advertisers that span the spectrum.  These advertisers range from large global brands to small and local companies. And ads are targeted by geography so global businesses can display local advertising easily. One more thing: you can use AdSense in many languages.

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 they’re continually refining their technology to make it smarter all the time.
For example, some words can have several different meanings depending on context. You’ve 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 longer—since they can search from right there where they are—and 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.
