As you know, Google has announced four new products yesterday, one of those products is named Google Co-op. Google Co-op enables you to create what are called "subscribed links," which basically allows you to create a Google SERP, define the title, description and the URL(s) to be displayed in the SERPs, for those who "subscribed" to your link. Danny defines this as "a giant and somewhat perplexing leap into mass tagging."

You can create an XML feed, submit your feed to Google Coop and then enable people to subscribe to that Coop. There are currently dozens of subscriptions available for you to be a part of at the Google Coop Directory, I personally set up my profile and subscribed to Fandango.com. Now, when signed in, if I do a search on movies I will be presented with;

Clicking on the top Fandango link takes me to here, clicking on the specific movies, takes me directly to those movies. I can also "edit" or "remove" the link, editing takes you to http://www.google.com/coop/subscriptions which basically enables you to "unsubscribe," not sure why I need the "remove" link then, but whatever.

It also works by searching on specific movies, like Goal! The Dream Begins, and it looks like;

The link takes me directly to that movie.

Why does it work? Because Fandango, submitted an XML file defining all those searches and for those who have subscribed to that subscription, they will be shown predefined results. How does that work? See the developer guide, I hope to create a few myself soon, that you can subscribe to.

Is it spamable? Ha. Well, lets give you the forum threads on this topic. I would call it more hackable, than spamable...
