According to press reports today, Google (NASDAQ:GOOG) is finally moving to pay-per-action ads!

What's next from America's most innovative company? A way to produce fire without the time-consuming labor of rubbing sticks together?

Pay-per-action ads have been around forever in Internet years, but they're not in favor with big Goo. It earns far too much money from the old (certainly not evil) model -- packing paid results at the top of the search-results page, where naive users confuse them with real results and click on them. That earns Google cash, but it doesn't necessarily pay a thin dime to the advertisers paying for that click.

Google's also a major gravy train for typo-squatters, sploggers, and sometimes, affiliated click-fraudsters, none of whom would make so much dough if pay-per-action ads were the norm.

I'm quite sure that explains why Google's pay-per-action scheme is being shunted away as an affiliate program, rather than becoming the Google mainstream. These ads won't appear on search results pages, because that would water down the special sauce that makes big Goo so tasty to shareholders. So while industry analysts are competing for the Sound Bite O' the Day award and talking up what a great "growth" opportunity this represents for Google, I call shenanigans.

Pay-per-action, in which Google gets paid only if its ads prompt consumers to actually do something that benefits the advertiser, puts more power in those advertisers' hands. Google has struggled against that for some time -- its obtuse click-fraud refund rules being a prime example. If pay-per-action becomes the norm, it will be great for advertisers sick of paying Google for traffic that doesn't earn them a penny. But it will shut off all that lucrative click fraud, splog exploitation, and meaningless curiosity clicks.

That could be a scary thing for Google shareholders. Perhaps that's why insiders like CEO Eric Schmidt are working so hard to make sure they're no longer counted among that group.
