what is adsense

Google AdSense is a free program run by Google that allows website publishers to earn money by displaying ads next to their online content. AdSense works by matching ads to a websites content and visitors. The ads are created and paid for by advertisers who want to promote their products. Advertisers bid to show in a real-time auction, and the highest paying ads show on the website. Publishers can earn revenue on either a per-click or per-impression basis. Google handles the process of billing all advertisers and networks for the ads on the website to ensure publishers receive their payments. AdSense ads can be text, images, video, or interactive media, and they are targeted to the site content and audience. Publishers can choose where they want the ads to appear on their site by pasting ad code on their site. AdSense is a participant in the AdChoices program, so AdSense ads typically include the triangle-shaped AdChoices icon. In 2021, over 38.3 million websites use AdSense.
