Google is making a smart move. Most of the bigger deal sites share an uncanny similarity - they are called "clones" for a reason. And the way to stand out is to offer better deals. I have gotten the Groupon newsletter since they came to NYC, and I have never bought a deal. And I am usually a very compulsive shopper. There is not enough variety and nothing is that compelling. The way to stand out is to target deals better so you can make money on margins instead of volume and offer more lucrative deals for businesses. FB may have as much data, but Google has shipped better big-data targeting than anybody else. You need to acquire, sort, and analyze the data, and then have the relationships to exploit your insights. And as location, purchase history, and timing come into play, the data is going to get big if you want to target deals well.
