AdSense is a tool from Google that lets website owners make money by showing ads. When you add AdSense to your website, it picks out ads that match what your website is about or what your visitors like. So, if your website is about books, AdSense will show ads related to books or reading.

Every time someone visits your website and clicks on one of these ads, you make a little bit of money. It’s like letting someone put up a poster on your website, and you get paid for providing the space.

Google handles choosing the ads and giving you the money, so you can just focus on keeping your website interesting for your visitors. AdSense makes it easy to turn your website’s space into cash without needing to do much extra work.
