I was wondering i have 4 sites now. They get decent bit of traffic but... i was wondering if someone clicked on my ad on one site... didnt know the other one was mine few days later and happend to click on another one on a different site... would i get in trouble for google for this.. i mean the chances of that actually happening is slim but just have to make sure... \
Take a deep breath and relax. You are worrying about things that don't need worrying about. Spend your time working on increasing traffic, improving ad relavancy, and getting higher-paying ads.
