Google announced last week that they will be expanding their test of the commission based product ads they started testing in June. Over the weekend, many started noticing the new type of ads in the Google search results.

A WebmasterWorld thread has some people taking notice.

Back in January 2008, Google began testing product (base) results in ads. They continued the test in October 2008 with expandable links to these ads. Then in February 2009, the ads became very well seen by many searchers. In May they tested one line product links and in August they tested open product ads. In April, I wrote how to get product images in AdWords ads. Keep in mind, some of these campaigns were not CPA driven, like the one I mention above.

Here are some live examples of searches that trigger these ads:
