I have always just used Google main search page network for advertising, however recently I started advertising using sites that have signed up for google adsense accounts on their sites. However I want to know how relevant the sites are that my ads are been placed on and then stop it if its pointless. Can someone advise how I can find out what sites they are displayed on? Thanks
... that you can't. Google don't provide you with this information so you have to either trust them or not use them. Good luck
