Why is Email Marketing important?

AdSense is Google’s advertising engine that enables website owners to include Google ads on their sites.

Google places these ads based on the content of the page and shows them alongside the main text. When a visitor clicks on one of these ads, then they are redirected to another advertiser’s webpage, and that advertiser is charged for their visit. Generally, for this service each website owner will get half the money made from an ad, meaning that with AdSense you can make some extra cash without any work as long as you have a functioning website.
