Google+ Has 400 Million Members
Google‘s social network Google+has more than 400 million members, Google’s Senior Vice President of Engineering Vic Gundotra has announced.
Gundotra posted the news on his Google+ profile today, adding that Google+ also has 100 million monthly active users — if you count in the mobile app.
“This week we also hit an important milestone–over 400,000,000 people have upgraded to Google+. It was only a year ago that we opened public sign-up, and we couldn’t have imagined that so many people would join in just 12 months,” wrote Gundotra.
For comparison, Google+’s biggest competitor, Facebook, had 955 million active users in July.
Of course, the methodology of counting active users (as opposed to the total number of users who’ve signed up for the service) between the two companies may differ, but judging by these numbers, Facebook is approximately 10 times bigger than Google+.
That may sound like a big advantage for Facebook, but one also has to take into account that it took Facebook several years to reach 100 million active users, while Google+ managed to do that within 12 months.

Google's PageRank System
The Google algorithm's most important feature is arguably the PageRank system, a patented automated process that determines where each search result appears on Google's search engine return page. Most users tend to concentrate on the first few search results, so getting a spot at the top of the list usually means more user traffic. So how does Google determine search results standings? Many people have taken a stab at figuring out the exact formula, but Google keeps the official algorithm a secret. What we do know is this:
Why is the Google algorithm so important?
Finding useful information on the World Wide Web is something many of us take for granted. According to the Internet research firm Netcraft, there are nearly 150,000,000 active Web sites on the Internet today. The task of sifting through all those sites to find helpful information is monumental. That's why search engines use complex algorithms -- mathematical instructions that tell computers how to complete assigned tasks.
Google's algorithm does the work for you by searching out Web pages that contain the keywords you used to search, then assigning a rank to each page based several factors, including how many times the keywords appear on the page. Higher ranked pages appear further up in Google algorithm search engine results page (SERP), meaning that the best links relating to your search query are theoretically the first ones Google lists.
For Web page administrators, being listed prominently on Google can result in a big boost in site traffic and visibility. In 2007, Google surpassed Microsoft as the most visited site on the Web. With that much traffic, getting a good spot on a Google SERP could mean a huge boost in the number of site visitors.
