The test is limited and Google has “agreements” with bloggers.

All your content are belongs to us… sorry what they mean is "We’re always experimenting with different ways to connect our users with high-quality and helpful information. "

Quite funny how all recipe posts have (frustratingly) a ton of content before you get to the recipe I assume to assist with ranking on their search and then Google just lifts the good stuff.

I wonder what the site gets as part of the agreement.
