Stay in Target implement Section Targeting.

Section targeting allows you to suggest sections of your text and HTML content that you’d like us to emphasize or downplay when matching ads to your site’s content.

Use section targeting to emphasize some content in your page. On your site, place this code where you want to emphasize.

<!– google_ad_section_start –>
Content you want to emphasize.
<!– google_ad_section_end –>

If you want some content to be ignored, use
<!– google_ad_section_start(weight=ignore) –>

In order to properly implement this feature, you’ll need to include a significant amount of content within the section targeting tags. Including insufficient content may result in less relevant ads or PSAs. In addition, please keep in mind that this feature should only be used to emphasize significant sections of your site’s relevant content.
