Google claims 90 million Google+ users, 60% "active" daily

ther daily or weekly.

"There are over 90 million Google+ users, well over double what I announced just a quarter ago," Page said. "Plus users are very engaged with our products. Over 60 percent of them engaged daily and 80 percent engaged weekly." (UPDATE: We've confirmed what some readers suspected: the 60 and 80 percent figures refer to users accessing any Google service—whether it be search, Gmail or something else—while logged in to their Google account, and do not necessarily indicate actual usage of Google+ each day or week. The 90 million figure refers not to active users, but to the total number of people who have created Google+ accounts.)

The increase in overall numbers, no doubt, is due in large part to Google making Plus links a prominent part ofsearch results, and integrating the social network into Google Apps, Gmail, Picasa, and, well, just about everything Google makes. Google+ is apparently growing fast, but still lagging behind Facebook's 800 million active users and Twitter's 100 million active users.

Page also touted growth of Android, Chrome and Gmail while announcing that Google hit more than $10 billion in quarterly revenue for the first time. Revenue for the full fiscal year ending Dec. 31, 2011 was up 29 percent and quarterly revenues were up 25 percent year over year. Net income for the quarter was $2.71 billion on overall revenue of $10.58 billion, up 6.7 percent over the previous year's $2.54 billion. Full-year net income was $9.74 billion on revenue of $37.91 billion. The quarterly numbers fell short of financial analysts' expectations.

Page boasted that Google is signing up many new enterprise customers for its Google Apps suite, including110,000 employees at BBVA, Google's largest business productivity deal that has been publicly disclosed. But advertising, as usual, is still Google's biggest cash cow, accounting for 96 percent of quarterly revenue, compared to 97 percent in the previous year's fourth quarter. Google said mobile advertising is a growing part of total revenue, but didn't specify how much it accounts for.
