1. After login to your blogger.com -> layout -> Edit HTML -> Expand Widget Templates
2. Find the following code
<div class='post-body'>
<p><data:post.body/></p>
<div style='clear: both;'/> <!-- clear for photos floats -->
</div>
<div class=’post-footer’>
3. Copy this code -> <div id='related_posts'/>
and put it between<p><data:post.body/></p>
<div style='clear: both;'/> <!-- clear for photos floats -->
</div>
and
<div class='post-footer'>
4. Copy this code
<script src='http://www.google.com/jsapi'/>
<script src='http://brps.appspot.com/brps.js' type='text/javascript'/>
And put it precisely ABOVE </body>
</html>
5. SAVE. Done.
NOTE: The position of code number 3 might differ from template to template. The point is you should put it so that it appears in single page (that is a page when you click a particular article or blog post), not in the frontpage / homepage of your blog.
