When advertisers pay Google to run ads for their businesses (with the Google AdWords program), they can opt to include their content on Google’s Display Network. If they do, their ads are eligible to show up in “slots” on participating websites.
If AdSense is active on your site, you’ll get to decide where these slots are placed. Then, Google will runs ads in those positions, based on what your site and content are about. The system is designed to automatically find businesses that are a good match for your niche and audience.
The result is that your ads are more likely to be clicked on than if you displayed random advertisements. In turn, your chances of receiving a higher payout are better. Of course, the boosted income isn’t the only benefit of using AdSense. The inclusion of highly-targeted ads can also help you provide a more tailored service for your customers.
Plus, the process is mostly automated – saving you a lot of time. What’s more, it’s completely free to join, making it a perfect option for small businesses.
