google-adsenseGoogle Adsense Section targeting allows you to suggest sections of your site’s content that you would like google to emphasize or ignore while matching ads to your site’s content.

I sometime back implemented section targeting on single/post pages on this blog and found it very effective, the ads on posts are now much more relevant to the content of the article. This will increase clicks on ads as the ads will be more related to the content the visitor is currently reading or interested in, especially if the visitor is from search engines.

How to implement Section Targetting on your website or blog?

You have to place HTML tags to your page’s code, the tags will mark the beginning and end of the section you want google to emphasize or ignore for ad targetting.
The HTML tags to emphasize a section of your page:

<!-- google_ad_section_start -->
<!-- google_ad_section_end -->

The HTML tags to ignore a section of your page, add(weight=ignore) to the starting tag:

<!-- google_ad_section_start(weight=ignore) -->
<!-- google_ad_section_end -->

you can suggest as many sections of page you like, it may take time for the results to be shown up, as it will only come into effect after the page is propely crawled by google bots.

Note: This will only work for the pages with significant amount of content within the targeted section otherwise it may result in less relevant ads or PSAs (Public Serving Ads). And do not try to manipulate the ad targeting to result in ads which are not relevant to the content of your pages as it is against the policies of google adsense.
