Insert Adsense Into Blogger/Blogspot Post
Adsense in blogger post is a such good placement. Here the way to do that. First, parse your adsense code so it can be inserted in Blogger XML Code. Blogcrowds have tool for parsing Google adsense code to Blogger XML Code. Just put your adsense code into Parse HTML box, then click Parse. Save your adsense code that have been parsed.

Next step is place your result into blogger template code. Go to Layout section, then Edit HTML. Check Expand Widget Templates. Find in your blogger template code something like this:

   <data:post.body/>

Place the code before that string if you want your adsense appear before post body.
You can also place your adsense after post body, just find code like this,

   <div class='post-footer-line post-footer-line-1'>

and then place your code after that string.

You can display adsense only in single blogger posting. See my another article in this blog about show adsense in blogger post or in home page only.
