Hi, is possible to tell to a particular code of ad sense, what part of your page to read, in order to get more specific ads? For example, my page talks about a place, the landscapes, the views, the attractions...and the HOTELS; and I want Ad Sense only to read the Hotel Part and put some HOtels Ads...is this possible? Thanks for your help
Sounds like you're interested in section targeting: https://www.google.com/adsense/support/bin/answer.py?answer=43872 and https://www.google.com/adsense/support/bin/answer.py?answer=23168
first read do and don'ts of ADSENSE rules. Follow them Otherwise you will be banned. You should not cheat the ADSENSE.
Adpubster is right, that feature is called "section targetting", as important tip : don't concentrate section targetting on small piece of content.
This is the code given from adsense <!-- google_ad_section_start --> your content here <!-- google_ad_section_end --> add this before and after your content. I use it and yes it helps for revelant ads
