Where to add ad unit code
After you get and copy your ad unit code, you need to paste it between the <body> and </body> tags of your page. If you paste the ad code outside the <body> tags it will prevent your ads from appearing correctly.
Example of an HTML page before ad unit code has been added
<html>
<head>
This is the head of your page.

How to position ads on your site with HTML
Just like the other elements of your site (images, paragraphs, etc.), you can change the position of your Google ads by using HTML tags (<div>, <table>, etc.). For example, if you surround your ad code with the HTML tags <div align="center"> and </div>, your ads will appear in the center of your page.
