Ken over at WebmasterWorld reports of a new feature for AdSense. In “What is section targeting and how do I implement it?” Google describes new tags which you can add inside the code of your page. A block where ads should retrieve their relevancy from is enclosed in
<!– google_ad_section_start –>
<!– google_ad_section_end –>
tags. There is also a feature to ignore paragraphs from ad targeting.
Jenstar however believes that it:
it is probably going to do some relevancy checking between what you tell it to ignore and not ignore, and make sure they are somewhat related.
Hopefully someone writes a WordPress plugin for it fast, so that you can easily select the tags while writing.
