Here is a nifty tip to increase your CTR while using this modification.
This ad placement is good to blend in with the post content, but it also, when someone or you make a post, try not to place any links inside the post. For example, instead of using
http://www.yoursite.com or
www.yoursite.com , just use yoursite.com. This way, the only links available for someone to click on are links to Google Adsense, YPN, or whatever publishing program you use.
Keep in mind that you are not forcing others to click your links, you are simply eliminating other "clickable" links while making your publisher links the only "clickable" links inside the post.
This is a great modification, thanks.
