Many of you have argued over time how to put an Adsense ad block on your iFrame page and still not violate Google Adsense Policy. Previously there was no explicit mention of iFrame in Google Adsense Policy. So many publishers tried to put some content on their iFrames and add Adsense ad block because the main condition was that you can only add Adsense code in a page if it has some content. But if you are still following this trick you might soon get into trouble. Do you know Google made a Policy change in last May and it has a major change? Now Google has mentioned explicitly in Adsense Policies that you cannot put Adsense ads in any iFrame:
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.
So if you are violating Adsense TOS, it’s high time to rectify it. Your luck might soon run out and you would become another addition to Adsense banned publishers.
