When Google Inc. launched its Google+ social-networking site three weeks ago, executives handed out sailor hats to the hundreds of employees working on the project, symbolizing their year-long journey to that point.
So far, the sailing has been mostly smooth. On Wednesday, Web-traffic watcher comScore Inc. estimated Google+ has had 20 million unique visitors since its launch, including five million visitors from the U.S. A Google spokeswoman declined comment.
Google’s rapid growth spurt on Google+ suggests that people are hungry for more social network options, WSJ’s Jen Valentino-DeVries reports.
ComScore, whose estimates are based on a “global measurement panel” of two million Internet users, similar to the approach Nielsen uses to measure television ratings,doesn’t have data on the number of minutes people spent on Google+.
Still, the growth of Google+ has impressed observers because access to it is by invitation only, meaning people can join only if a current member invites them. And the company hasn’t yet marketed the service to the more than one billion monthly visitors who use its search engine, Gmail and other services.
