Adsense hidden in 1x1 iframe

why?

[zomega42]

I just noticed a popular site in my niche is putting Adsense in a 1x1 iframe on the homepage. What possible good is this doing anybody?

It seems fishy, but I can't find the rat. It's impossible to click the ads, so I don't see how this is going to make them any money. What on earth is going on here?

Could be a coding error from a coffee-deprived coder mistyped the width & height values.

I can't see any reason to do it.

Invisible CPM ads maybe?

Sure sounds fishy.

[zomega42]

Yes I suppose they could be trying for invisible CPMs. Another thing that occurred to me is that he's creating fake impressions to hide clickfraud happening elsewhere. Or maybe once every thousand impressions that 1x1 iframe is somehow redirecting to produce a fraudulent click, if such a thing is possible.

Invisible CPM ads maybe?

My thoughts exactly. That sounds like a person that does not want to "clutter" their site with ads, but still get the scratch...

Lame if it's true, sooo lame....

Assuming it's their ad code to begin with. This would be a good way to smart price the hell out of your competitor or to get them banned from AdSense altogether. I'd report this site to Google.

[zomega42]

Yes I will report them. The site owner has a history of abusing Adsense, so I don't think it's a coding error. The site used to hide the "ads by google" by editing the JS code to change the size of the ad, but they don't do that anymore so I assume Google eventually told them to stop.

Well you had the answer since the beginning: Impressions(CPM) fraud.

Even I think it could be fake impression technique for image ads.
