There is a simple way how to put AdSense in the middle of a Blogger post, only with JavaScript and a group of some DIVs. Within 2 easy steps:
The first step:
Please log in Blogger, then the layout select edit HTML. In your Blogger template, find the tag <data:post.body/> (you must check Expand Widget Templates in Blogger console) and replace it with following code:
<div expr:id='"aim1" + data:post.id'></div>
<div style="clear:both; margin:10px 0">
<!-- Your AdSense code here -->
</div>
<div expr:id='"aim2" + data:post.id'>
<data:post.body/>
</div>
<script type="text/javascript">
var obj0=document.getElementById("aim1<data:post.id/>");
var obj1=document.getElementById("aim2<data:post.id/>");
var s=obj1.innerHTML;
var r=s.search(/\x3C!-- adsense --\x3E/igm);
if(r>0) {obj0.innerHTML=s.substr(0,r);obj1.innerHTML=s.substr(r+16);}
</script>
Note that you must replace <!-- Your AdSense code --> with block code provided by Google.
Step two:
In every blog post: Put a special comment
<! - Adsense ->
in the exact point you want to appear AdSense advertising.
Google automatically inject in your posts up to 3 AdSense blocks. So just the first 3 posts (in a top-down order) in your home page or archive pages will have ads.
