There was a good article on the New York Times about Google’s spooky social network, Google Plus.
Some quotes from the article;
Thanks to Plus, Google knows about people’s friendships on Gmail, the places they go on maps and how they spend their time on the more than two million websites in Google’s ad network. And it is gathering this information even though relatively few people use Plus as their social network. Plus has 29 million unique monthly users on its website and 41 million on smartphones, with some users overlapping, compared with Facebook’s 128 million users on its website and 108 million on phones, according to Nielsen.
Starbucks, for instance, has three million followers on Plus, meager compared with its 36 million “likes” on Facebook. Yet it updates its Google Plus page for the sake of good search placement, and takes advice from Google representatives on how to optimize Plus content for the search engine.
“When we think about posting on Google Plus, we think about how does it relate to our search efforts,” said Alex Wheeler, vice president of global digital marketing at Starbucks.
