When Google Adsense contributes half of our earnings online, it is very important that we keep track of their policies changes. Especially when we constantly trying out new ways to increase Google Adsense earning, sometimes we might accidentally step into the prohibit zone. In order to play the game well, we need to learn up and understand the rules of the game. As Google Adsense always makes changes on the program policies, we need to keep up with the changes to stay on the game. Once we get two yellow cards or a red card, than it’s game over.
Check out the latest blog post title “Clarifying our ad implementation policies” from Google Inside Adsense Blog as it explains the modification of Ad Behavior policy related to iframe usage. Below is the part which the modification toke place:
AdSense code may not be altered, nor may the standard behavior, targeting or delivery of ads be manipulated in any way that is not explicitly permitted by Google. This includes but is not limited to the following: clicking Google ads may not result in a new browser window being launched, nor may Google ads be placed in an IFRAME.
In other words, try not to use iframe if possible. It seems like Google will be more proactive about enforcing the misuse of iframes. It will be better to just stop using iframes to avoid any troubles which might affect your earnings.
