AdSense is a free program that allows publishers to earn money by displaying relevant ads on their websites.
To simplify, it is a money-making tool for website owners. When you have a website and you want to earn some extra cash, you can sign up for AdSense. It allows you to display ads on your website that are relevant to your content.
When people visit your site and click on these ads, you earn a small amount of money. It’s like renting out space on your website for advertisers to promote their products or services. AdSense takes care of finding suitable ads for your site and handling the payments, so you can focus on creating great content. It’s a way to monetize your website and earn revenue through online advertising.
