By default, Google will display ads at the top of your results and on the right-hand side.
You can choose not to display ads at the top of your results. (Note that if you've linked your search engine to your AdSense account, disabling top ads may result in decreased revenue from ads on your site.)
Disable ads at the top of results:
- On the Control Panel, on the left-hand side, click Setup and then click Make money.
- Switch Ads layout: Allow ads at the top of the page to OFF.
