I added AdSense ads inside the posts of two blogs that have not had a high click through rate. In a month or so I’ll come back to this post and let you all know if it makes a difference. Google AdSense limits you to 3 ads per page so you’ll have to knock off some of those other ads if you are going to do this.

1) Go to template -> Edit HTML -> check expand Widgets
2) Find the line: <p class=’post-footer-line post-footer-line-3′ />
3) Add <div id=’ads’></div> on the next line
4) Go to AdSense and create your ad text
5) Remove all > and replace them with >
6) Remove all < and replace them with <
7) Paste the new ad text between <div id=’ads’> ad text goes here </div>
