[qi:011] Update: Hey Michael when you say, “Om Malik says Facebook traffic is tanking” it is not quite true. As I said in my original Facebook-traffic post from late last night, I don’t quite buy it. My exact words, “It just doesn’t make any sense! Unless of course, the unthinkable is happening. I hope to chat with FB tomorrow and get more on this.”

Well, I haven’t been able to get Facebook to respond, but I did talk to others and have gotten to the bottom of this “dip/tanking” issue. Paul Sutter, co-founder & president of Quantcast explains that the dip we are seeing is because of the panel model adopted by comScore.

ComScore has a panel that has a bias toward Internet users who log on from home. The same is true of all measurement panels – Nielsen, Hitwise or Quantcast. As kids go back to school, they vanish from the panel, even though they are still using Facebook, from school dorms. “We have a hybrid model, a combination of panel and direct measurement,” he says. Direct measurement means a website places a Quantcast pixel on their website and that is used to measure. Sutter points out that their own panel also saw a similar dip, but in reality if direct measurement was in place, the traffic should go up.”

ComScore’s Andrew Lipsman disagrees with Quantcast explaination.

Quantcast’s claim that the comScore panel has a home bias is nonsense. comScore’s panel includes home, work, and university audiences and each sample is weighted and projected according to the size of the respective Internet population.

Of course, it would help, if Facebook explained what’s the story.

Facebook spokeswoman just got in touch from London and explains….

It’s important to note that we focus on active monthly users rather than registered users. Active monthly users in the U.S. grew from 17.7 million in August to 19.4 million in September. This active monthly user base has been growing at a rate of about 3 percent per week since January 2007 which means we have been doubling about every six months. Globally, we ended September with 44 million active monthly users as compared to nearly 9 million active monthly users for the same month in 2006. Our page views have also been increasing and went from 54 billion page views for August to 57 billion page views in September.

That settles it for me!

(My original update is below the fold with information and data from ComScore and Hitwise.)

Well well well….thank God for my disbelief. The 9.3 percent decline in unique visitors and 3.8 percent decline in page views for Facebook in September are part of a historical pattern. Hitwise and comScore have both confirmed this information. Andrew Lipsman of comScore left a message in response to our previous post:

Last year, there was a similar dip in visitation at Facebook, which suggests there are some seasonal factors at play. Another important factor that has not been mentioned is that September has 1 fewer day than August. Assuming all other things are equal, there would be approximately 3 percent less traffic in September just because it has fewer days. So a fair portion of the decline can be explained by that factor. Always be careful in looking at one month trends, because seasonality can always be an issue.

The Hitwise spokesperson had this to say, in addition to the historical chart they sent our way:

There is a small dip for Facebook in terms of U.S. visits it appears for the last few weeks, but looking back over time this could be more seasonal than anything. We’ll know more in the coming weeks.

We are still waiting to hear back from Facebook. More when I have that information.

Update: Andy from Marketing Pilgrim got this information before I did. Good work Andy!

  1. Om, if you’d read my comment I left on your previous post, you’d have had this data hours ago. :-(

  2. Hey Andy

    I was on the road, and also I wanted to wait for the guys from Facebook to get back. Anyway good work. Sorry about not being able to link it.

  3. No problem, being on the road is a pain for all bloggers. Thanks for the link.

  4. Since all the measurement panels (Comscore, Netratings, Quantcast, Compete, Hitwise) share this same home-bias flaw, all of these panel measurements will show the same flaw.

    Direct measurement is really the only way to solve this problem.

  5. This has created such a stir, funny how the explanation doesn’t get as much play. Good find!

    You should also have Comscore comment on what would be a simply monstrous flaw in their methodology. If this is correct Comscore is misreporting traffic all over the place. The home bias would affect many sites in different ways.

    Measurement “experts” huh? “LOL”

    Om Malik wrote a post last night about a Facebook traffic drop but was skeptical of the validity of the information. Today Om explained the drop in an update post where Paul Sutter, co-founder president of Quantcast told him the

  10. The huge increase of Facebook´s traffic in Europe will compensate this small loss in US i believe.
