Earlier this week, we reported on Compete’s numbers for Google+’s unique audience growth in the U.S., as pointed out by Kontxt communication consultant Morten Myrstad in a post on Google+ itself. For a ghost town, as many seem to consider it, Google+ seems to have grown pretty significantly from month to month.

Today, Myrstad posted on Google+ growth again, this time citing global data from comScore.

“According to comScore, Google+ had 110,7 million unique visitors worldwide in June,” he says. “Compared to last November, this is a growth of 66%. In the U.S., the growth is even higher, with an 82% growth from November to 27,7 million unique visitors in June.”

“In pure numbers, Google+ according to comScore grew from 66,7 million visitors worldwide last November to 110,7 million visitors in June,” he adds. “This is a growth of 66%. With 110,7 million unique visitors during a month, from desktops only, the comScore data also seem to confirm Google’s own published data: 250 million accounts, 150 million monthly users and 75 million daily users worldwide. According to the comScore data, 25% of the Google+ worldwide visitors in June came from the U.S., up from 22,8% in November last year.”

Myrstad notes that comScore’s data (as well as the Compete data) only represents desktop use, and does not mobile use, which Google’s Vic Gundotra has indicated is higher.

Google+ certainly doesn’t have the users of rival Facebook, but considering how young it is, and how much Google will continue to push it into its various products (including search), it’s very likely that the growth will continue.
