Google AdSense is a program run by Google that allows website owners to display targeted advertisements on their websites. When a user visits a website that is part of the AdSense program, Google will display ads on the website that are relevant to the user’s interests. Whenever a user clicks on one of the ads, the website owner will receive a share of the revenue generated from the click. AdSense is a popular program for website owners because it is relatively easy to set up and use, and it provides a way for them to earn money from their websites. To participate in the AdSense program, website owners must apply and be accepted by Google. Once they are accepted, they can then display AdSense ads on their website.
