You can offer advertising space on your site directly to businesses that want to appear alongside your content. That’s called a direct deal. You can also use an ad network – such as Google AdSense – to sell your ad space on your behalf. The way AdSense works is by serving ads that are relevant to the content appearing on a specific page of your blog. For example, if your blog is about adventure travel and you’ve just uploaded a post about a trip to Rekyavik, AdSense might show an ad about travel insurance, Iceland or warm clothing. As the owner of the site where the ad is appearing, AdSense pays you when a user views or interacts with an ad.
