AdSense lets you customize the appearance of ads to match the look and feel of your site. You can also customize the style of your AdSense for search box and search results page.
You get paid whenever someone on your site clicks on one of the AdSense ads. Advertisers can also bid to appear on your site on a CPM (cost per thousand impressions) basis. Both CPC and CPM bids compete in our AdWords program to ensure that you optimize your ad revenue.
