Good news, You can now make Google Adsense’s Ads more targeted! By implementing section targeting, you can suggest section of text to show only related ads. This feature is pretty useful especially for blogs and news sites.
The feature is fully automate. You only need to add in a few lines of code in your HTML. For example:
<html><head><title>Section targeting</title></head>
<body>
<!-- google_ad_section_start -->
This is the text of your web page. Most of your content resides here.
<!-- google_ad_section_end -->
<!-- google_ad_section_start(weight=ignore) -->
This is the text of you want to ignore. Mostly are those text section that contain 'blog' related keywords.
<!-- google_ad_section_end -->
</body>
</html>
Anyway, it takes up 2 weeks time to see the result and the result is not always guaranteed.

Thought: Google says “… it may take up to 2 weeks before our crawlers take into account any changes you’ve made to your site.”. Isn’t Google adsense’s crawlers do its job on the fly when it’s loaded from a web page? Why google says it will take 2 weeks for their crawlers to do the job? Are they using Google search engine’s crawlers? Then, are google search engine’s crawlers related to Google Adsense? Will a page with higher pagerank in Google search engine getting higher paid for Adsense … ? Hmm … thinking too much
