Matt on Marketing

The reach of +1 so far is small, but the impact could be enormous. Here's why.

Right now, Google search results tell you what Google thinks is most relevant.

With +1, those same search results will tell you what your friends, peers and colleagues deem most relevant as well.

This brings word-of-mouth directly to the discovery fire-hose.

SEO tactics will continue to be important. Relevant content will still rank. But products and services with the best reputations, the best service, the best public support from customers and fans - those social rankings will matter more than ever.

The reach of +1 is limited, but that's temporary. Get ready.
