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.
Disreputable display advertisers use IFRAMEs, or inline frames, to manipulate targeting through keywords or hide the “Ads by ____” label so visitors think the ad is part of a site’s content. Google was quiet about the change because it’s a move the company should have made a while ago. AdSense publishers who use IFRAMEs — holdouts from the late 90s — for embedding Google ads on pages will have to change their ways.
Another small change made last week in the Program Policies was the exclusion of chat programs as acceptable outlets for AdSense publishers to place Google ads, search boxes or search results.
At JenSense, Jennifer Slegg contemplates whether Google is “working on their own end-user chat application where publishers could add a Google chat program to their websites that they could earn AdSense earnings from the ads displayed. It wouldn’t take much for many AdSense publishers to switch from a third-party chat program — especially since many of them charge for the service — and utilize a Google one they could earn money from.”
That’d be a nice little money-maker for Google and publishers alike. If the company isn’t working on it, it really should start…
