Do you really think people click on google ads. Before I knew what google adssense was I use to ingnor those ads on the side or at the bottom. Now that I have some knowledge of it I click on them more often.
Same here, I though those ads are not safe or sort of a virus. I am very paranoid on viruses because of ignorance. Now that I have more information I do click on them.
Never click the ads just to get some dollars for the publisher because it is the advertiser who suffers from such activity without any conversion. Click it if it really interests you. There is no safety from the adsense point of view. Google will track the clicks and soon will disable the account. Stay away from clicking your own ads...
