It’s dependent on traffic. Traffic goes up and down and you never know when it is going to do a major dip. Most advertisers pay based on the number of views their ad will get. This turns you into a traffic monster. You start to look for creative ways to get any kind of traffic, no matter if it’s good traffic or not. This can easily lead to your site becoming another junk site that you try to avoid.
Adsense is a contextual advertising network that places partner (business) ads on your website. It’s easy to set up—all you have to do is copy and paste some code given to you from Google in the places you'd like the ads to appear on your website. Google will then show ads from advertisers that are a match to the content on your website so that ideally your website visitors see relevant ads.
Make it easy for readers to browse – If you want more pageviews, you should make it as easy as possible for readers to read your other blog posts. You will want to make it easy for readers to find your blog homepage, categories, tags, search bar, and so on. Also, I recommend including links in every single one of your blog posts, so readers can easily find related topics.
