Step 1. Go to your dash board and click on Editor as shown below
Step 2. Click on the Header template on the right

You can try pasting the code between the lines below for testing purposes,
=============================================
<div align=”center”>
<script type=”text/javascript”><!–
google_ad_client = “xxxxxxxxxxxxx″;
/* 728x90Leaderboard */
google_ad_slot = “xxxxxxxxxxx″;
google_ad_width = 728;
google_ad_height = 90;
//–>
</script>
<script type=”text/javascript”
src=”http://pagead2.googlesyndication.com/pagead/show_ads.js“>
</script>
</div>
=============================================
when done with that , Click
,
Then load your page to see if it worked.
If it works well you’ll see the 728×90 Leaderboard advert centered nicely just below your header image.
Do not forget to replace the ” xxxxxxxx” above in the [ 1-google_ad_client and 2-google_ad_slot lines] with the your own specific data.
