Google GBuy and AdSense CPA Ads

A week after Google Blogoscoped published about Google CPA Ads, The Wall Street Journal(WSJ) reported that Google gets ready to test GBuy.

Google CPA Ads — You get paid whenever a site visitor clicks on the ad on your site and perfoms a specified action, such as generating a lead or purchasing a product.

GBuy — Google’s version of PayPal like online-payment service.

How does GBuy work?

According to WSJ, the GBuy service will work like this: You search for product keywords like “shoes” or “strollers” on Google, then you will see the AdSense text ads with GBuy’s symbol or icon. If you click on the ad, you will be linked to the merchant’s site and the checkout process there is integrated with Google GBuy.

How does GBuy related to AdSense CPA Ads?

Here is my bold guess: After Google announced GBuy online payment service, Google will add the new GBuy ads format into Google AdSense, which is a AdSense CPA ad.

Then, AdSense publishers put up GBuy ads on their websites and make money from each GBuy sales. It is possible that AdSense publishers get revenue from GBuy ads clicks too.

My two cents

Generally, CPA ads pay more than CPC ads (e.g. current Adsense ads) because CPA ads usually lead to product sales. It would be great if the “GBuy ads” support both CPA and CPC.

However, I afraid Google will ban other CPA ads on the same website as AdSense CPA ads, just like Google disallow other contextual ads on a web page with AdSense ads.
