Google First To Hit 1 Billion Unique Users Per Month Mark

Google became the world’s first internet company to reach over 1 billion unique users in a single month on its websites. According to a recent report from comScore, during the month of May, Google-owned websites (its search engine, Gmail, and YouTube, among others) scored more than a billion unique visitors, an 8.4 percent increase since the year 2010.

Google is approximately 100 million users ahead of Microsoft’s sites, the second most visited destination of the internet, with 905 million unique visitors. Facebook stands third with 714 million users, a 30% increase from the previous year. Since 2006, Google’s number of unique visitors has increased more than twice in size, from 496 million unique users, when comScore began measuring sites’ unique visitors, to over 1 billion today.

The Wall Street Journal explained comScore’s measurement methodology:

ComScore’s estimates are based on its “global measurement panel” of two million Internet users, similar to how Nielsen measures television ratings. ComScore refines the estimates with “page view” data that it receives from more than 90 of the 100 publishers of Web content, but not from Google.

A research released by Hitwise (firm providing online competitive intelligence) in December 2010 showed that Facebook outnumbered as the most-visited website of the year 2010 among U.S. users. However, with all the Google-owned properties combined, Google still had a greater share of visits (9.85% to Facebook’s 8.93%).
