My reader has made it clear that it want direct answer on how put one ad banner in her blog, and wants put it after the first post. Here’s how you do:
To make this is simple, all you need to make is to paste this code below in your index.php (Presentation > Theme Editor > Main Index Template).
<?php if ($count == 0) : ?>
paste your ad code here
<?php endif; $count++; ?>
As you can see from this detailed image below once you have paste the script on your index.php

Replace the text “paste your ad code here” with your own ad code and save your index.php. Very useful! This small script allows you to adding banner after the first post.
I like to make things harder and be different that is why it took me a while to finally use this script
