Facebook U.S. unique users down 4.8% in 6 months

(MoneyWatch) A recent report from analyst firm comScore said that unique U.S. visitors to Facebook (FB) dropped slightly in May compared to April and March. But an analysis of additional comScore data suggests that the slowdown could be more significant and longer lasting. Falling traffic could be a concern to investors, who justify Facebook's high market value by pointing to its growth potential.

Unique visitors are an important measure of growth and activity for social networks and an indicator of whether users might be tiring of a site. According to Reuters, research firm comScore said that the number of unique visitors was 158.01 million in May, down from 158.7 in April and 158.9 in March, which would represent a 0.6 percent drop. Year over year, the May number was up 0.5 percent, taking into account a change comScore made in how it calculated traffic.

Over a six month period, however, my analysis of additional comScore data shows that Facebook has seen a 4.8 percent drop in unique U.S. visitors. Facebook's growth prospects became a crucial issue in the company's disappointing IPO after news that a Morgan Stanley analyst had warned clients that the social networker's revenue outlook had dimmed. Tim Beyers, senior analyst at The Motley Fool investment site, said the news wouldn't necessarily keep him from buying stock, but "it would make me look at the growth strategy."

Two years of comScore's top 50 sites monthly data, based on U.S. unique visitors, shows that the number of unique U.S. Facebook visitors peaked last November at 166 million. It has been generally declining since. Below is a graph that shows the number of "uniques" for Facebook between May 2010 and May 2012.

Analysts and investors have been concerned about Facebook's future performance since the company's IPO, with slowing growth a major issue. Another worry was Facebook's revelation that it does not make money from  mobile users -- especially because mobile looks like the growth area. Furthermore, according to SEC filings, half of Facebook's revenue in the first quarter of 2012 was from the U.S. and Canada, down from 52 percent in all of 2011, so audience size in North America is critical to the company's ongoing success.

According to comScore's numbers, which aren't adjusted for a change in the firm's methodology, there has been a general downward trend in the number of U.S. unique visitors since November 2011. If Facebook were still growing, the methodology change should have shown a single drop, representing the correction, and then a continuing upward trend. Facebook did not respond to a request for comment.

Nielsen data also suggest a drop. According to Nielsen's numbers, Facebook had 156.2 million uniques in November 2011, 152.8 million in March 2012, 151.4 million in April 2012, and 152.7 million in May 2012. That 2.2 percent drop would still be significant, although lower than comScore's report.

It isn't the first time comScore has shown a downward trend in Facebook uniques. Between December 2010 and February 2011 there was just under a 2.1 percent drop, so there is a possibility that Facebook has some sort of seasonality, although the current downward trend is already longer than the previous one.

A problem for Facebook

The problem for Facebook is that the company's steep market valuation -- it trades at about 80 times trailing revenues -- is based on further revenue growth. That could happen in two ways: more users or more money made per user. Over its history, the company has an impressive track record of gaining users but it hasn't done as good a job of monetizing the ones it has. Last year, it made on the average only $5.11 per user. Furthermore, its greatest user growth has been in regions where the revenue per user is lower. Facebook is working on a way to better target advertising according to Beyers and, presumably, achieve higher ad rates. "We don't know how good that is yet," he says.

In its most recent quarterly financial filings with the SEC, Facebook claimed more than 900 million monthly active users, based on its internal data. According to the company, the term active user can include people who don't go to the website, but "took an action to share content or activity with his or her Facebook friends or connections via a third-party Web site that is integrated with Facebook." It may be that an increasing number of people are sharing content and opinions through Facebook but logging onto the site less frequently and, as a result, seeing fewer ads and generating less revenue.

Another possible explanation of the recent drop would be if a growing number of people came to use Facebook only from a mobile device and not, in addition, a desktop computer. ComScore and Nielsen can have difficulty identifying when a person visits a site through multiple devices, so if users moved from access through a desktop browser and mobile app to just the mobile app, it would look like one fewer user.

Facebook's stock price climbed 10 percent last week, yet still has not climbed back to its IPO price. If the company starts to lose users in its most productive customer segments, it will face further pressure to increase the amount it makes from those who remain.

Just like MySpace, Facebook has peaked and is headed down the slow slippery slope of falling out of favor with an easily distracted public. Soon some other social network site will be the big thing. Facebook is speeding this process up with their over aggressive ads and their constant changes.

But....I made thousands and thousands of friends....now what ?

I've never trusted or used Facebook.

Their "privacy settings" are a total joke, change constantly so you have go to back in and reset them, and even if you have everything possible set to "private", they're still selling your personal data.

No thanks.

And I wonder if more and more people aren't wising up to that fact.

FB's user counts seem misleading. Shouldn't the amount of users equal one per person? It seems a majority of FB pages are bringing attention to a cause or promoting an individual. How can ads directed at this type of "user" really be effective?

[knoesgaard]

People still use facebook?

Social interaction is overrated.

[RSMsky]

The slide at Facebook is not at all surprising. At your next social gathering ask, "What do you think of Facebook?" and the response will now range from a muted "meh" to "I'm sick to death of Zuckerburg's smirking face and the relentless theft and sale of my private life." No reflective person will seriously claim that Facebook has added any real or enduring value to social life simply because this datebook *** mega-scam has diluted and now polluted the bonds between human beings. A trashy undergraduate stunt sold for $100 billion.

I also saw, in a recent phone update, a facebook app applied - without my consent or permission, and it HAS sent 100k of fluff from my phone. After a number of steps, the applet is disabled, but the usual whiners who say "If you don't want it don't use it" may not have a clue that some of us who don't want it see it being used without our consent anyway.

It's good to see the numbers down. The place is a joke.
