Your ad is displayed to people who are already searching for the kinds of products and services you offer. So those people are more likely to take action.
You can choose where your ad appears -- on which specific websites and in which geographical areas (states, towns, or even neighborhoods).
Block unwanted ads: You can filter competitive ads, or other ads you want to keep off your site. Choose your own default ads: In the unlikely event that Google can't show targeted ads on your page, we'll let you display a backup ad of your choice. Customize ads to complement your site: We let you customize the appearance of your ads to match your site's look and feel. Track your earnings with online reports: With Ad Sense, you can monitor your ad performance with customizable online reports that offer details like the number of ad impressions, clicks, and click-through rate. Get ads on your high-end mobile website: With AdSense for content, we'll deliver the best optimized ads, whatever device your users happen to be viewing your site with.
