I have been playing with blogspot lately, and I have read many articles saying that the best place and format for an Adsense ad is to use a 300×250 ad right below the post title on each post.
Say, if you want a 300×250 Adsense ad on your left hand side with your blog text wrapping around it, first you get your Adsense code from your Adsense account, and then convert your Adsense code to html code, i.e. something blogspot can understand. Here is a great online tool at http://www.eblogtemplates.com/blogger-ad-code-converter/.
When you have the code ready, sign in to your blogspot account, click “layout”, click “edit html”, check “expand widget templates”, scroll all the way down, somewhere in the middle, you will find "<data:post.body>", right above that, paste the following:
<div style=’float:left; margin-right:10px;’>
.. add your converted code here…
</div>
Now you have a 300×250 ad right below your blogspot post title with your blog text around it, if you want it to appear on the right hand side, use the following:
<div style=’float:right; margin-left:10px;’>
.. add your converted code here…
</div>
