i am seeing very poor targeting. infact there are only 3 ads which are showing up on all pages of my website. am not sure what to do now this is the first time i am having troubles with ad targeting, the site is in adsense for more than 2 years and there was no issue at all with ads targeting. and the site is having pages in different categories from business to stocks, health or sports. no ads in any section, just simple default ads
You can try using section targeting: https://www.google.com/support/adsense/bin/answer.py?answer=23168&topic=371
When did you install the AdSense code. It takes a while for the bot to visit your pages and to have relevant ads shown, so if the pages are new or you recently added the code, give it a bit more time.
