As some of you may already know, if you're not getting very relevant AdSense ads, you can use <!-- google_ad_section_start -->
and <!-- google_ad_section_start(weight=ignore) -->
to direct the MediaPartners bot to focus on your content areas.
Has anyone has a very noticable increase in AdSense revenue after implementing this? How long does it take AdSense to catch on after implemented?
Thanks!! :)
