How to add AdSense to your blog

First, you must have an AdSense account. If you don't have one, apply to join the program. There are bloggers who have got approved AdSense accounts and they may put referral buttons on their blogs, and you can apply for an account via the referral buttons on their blogs. One of the blog is AdSense Alert (close new window to get back to this page), which also have more details about the AdSense program. This blog itself is another site. You will first need a site with reasonable content for them to review. The easiest way to get a site is to start a blog. A friend of mine got his application approved with a blog with just one post. There are various ways to earn through AdSense and they are described in this post: How do I earn from Google AdSense (close new window to get back to this page). You must then generate the scripts for the ads, referral buttons or searchbar.
