Like any other search engine, Ecosia earns money from clicks on the search advertisements that appear above and beside the search results.
Advertisers pay Ecosia a few cents for every click on an ad – or a portion of the purchase price made through an affiliate link. Ecosia gives at least 80% of the profits from this ad revenue to its planting partners' projects.
As the web surfer or shopper, you pay nothing extra. You can surf the web and support tree planting for free!
