1. Difference bet. contextual & Site Ads 2. How do i know which sites are displaying Ads on my sites ?
Ans: 1] Contextual means Ads which are relevant to the content of your page.. (eg if you write about Dogs, you will see ads about dogs) 2] If your using Adsense, then don't click on your ads, but see the URL below the ads or use this method: http://tech-buzz.net/2006/10/04/running-adsense-ads-on-test-mode/
