DuckDuckGo makes money primarily through two types of advertising.
Sponsored links
Sponsored links are advertisements that appear in a yellow highlight above search results. Sponsored links are currently syndicated through Microsoft adCenter. To advertise on DuckDuckGo through adCenter, sign into adCenter and look for the "Network Distribution" setting. Make sure the setting is set to "All Bing and Yahoo! search networks and syndicated search partners".
Affiliate sales
DuckDuckGo is part of the affiliate programs of some eCommerce websites like Amazon and eBay. When you visit those sites through DuckDuckGo and make a purchase, we receive a small commission. For details on this, check out our privacy policy.
