What is it ?

Section Targeting allows you to specify which parts of your text and HTML content that you want to emphasize or downplay when matching ads to the content of your site. By submitting your suggestions, you can help us to improve your ads. We recommend that only those familiar with HTML attempt to implement section targeting.

How It Works

To implement section targeting, you need to add a set of special HTML comment tags to your code. These data indicate the beginning and the end of the section you want to emphasize or de-emphasis on the ads.

When you put a tag given by google <!-- google_ad_section_start --> the adsense take it as the beginning of the content area from which the relevant ads are to be matched till this end tag <!-- google_ad_section_end -->

You Should have more content for properly utilizing it. Including insufficient content may result in less relevant ads or PSAs.Along with this you have to keep in mind that this feature should only be used to emphasize significant sections of your site’s relevant content.
