That will be a crap option. If PPC fraud is a problem this will cause a more unsolvable one. Smells like a suicide action

Looks like they AdSence publishers just got this option available, so AdWords should be available shortly (https://www.google.com/adsense/new item#3).

I tried running a site targeted, impression based campaign. I selected sites based on Google’s suggestions, using their site tool. I was immediately impressed with the number of impressions and clicks coming from some of the sites. One site seemed to be doing a little too well, so I went to the site to see how and why my campaign was getting so many impressions. However, when I went to the site, there was one little problem. They were not running Google ads - anywhere!

I searched through the entire site, and I could not find any Google ads. I wrote Google to inform them that it appeared a fraud was being committed by the site in question. The reply stated that the site had been removed from the Google Ads program. However, another search that day still returned the same site in the suggested results on Google’s AdWords site suggestion tool. I wrote Google again to clarify that I wanted to complain about what looked like fraud. This time Google replied with a refund offer, but made no mention of fraud or any actions they might take to ensure this would not happen again. Furthermore, as of today, the offending site still comes up in the “available sites” list using the site tool.

Now I am left to wonder who is committing the fraud - Google, the site in question, or both. Google has a vested interest in getting impressions for my ads. Therefore, if they could falsify a few thousand ads views and clicks here and there, who would notice as long as the numbers per offense were small? If they did this to a large number of companies on a very small scale per company, who would be the wiser? I am not saying this is what happened, but I am now very suspicious of their numbers.

Yes, indeed. I tried this the other day, and was very unhappy with the results.

Lets just say that I say very few clicks, and a whole lot of impressions. So much so, that the average cost per click was way more than what I was used to paying for a "click".

I would suggest for those that are interested in site-targeted ads that they really watch those numbers .... impressions are so hard to justify from a pubisher and advertiser stand point.

1000 impressions = .25 cents
10000 impression = 25.00

Google could put your lights out in a blink if you are not careful.

1,000,000 = 250,000 dollars (better start filing for bankruptcy)

Personally, I would stick to the CPC model, as it will give you more "bang" for your "buck"

Just my 2 cents.
