John Gruber mused today on why there is a disparity between the marketshare of Android and its share of web traffic. He theorized that "an awful lot of Android smartphones don’t really get used as smartphones."

That may be part of the story, but I think there is better explanation, and thanks to Akamai, we have data to support it.

In June, Akamai released Akamai IO which provides us with a view of the web we’ve never had access to before. It aggregates web browsing data from Akamai’s clients.

For those unfamiliar with Akamai, they are a content delivery network that is used by many major web properties. The means that their data is likely to be a more accurate reflection of web traffic than we’ve had from other sources in the past. They see more data and the sites their clients have are the popular, mainstream sites that everyone visits.

What Akamai’s data says about mobile web browser share

Enough background, let’s take a look at some data. First, this is what Akamai shows for mobile web browser market share over the last 30 days:

No real surprises here. Mobile Safari leads Android in web browsing usage by a significant margin as others have reported in the past. What gets interesting is when you look at traffic by type of connection. First up, non-cellular networks:

Again, no big surprises here. If anything, Mobile Safari’s lead over Android has increased. What about if we look at traffic on cellular networks?

Now that’s interesting isn’t it? iOS and Android are neck and neck when you look at web usage on cellular networks. So the question becomes not why do Android users not browse the web as much as iOS users do, but why don’t they browse the web on Wi-Fi connections?

Caveats apply

It is important to note that while Akamai’s data is better than what we’ve had before, it isn’t perfect. On the question of whether or not the data has a bias, Akamai says:

Currently, yes – most of the Web sites sampled for the Akamai IO Beta are focused on a U.S. audience. Therefore, while the data in the reports includes many visits from across the globe, it is biased in favor of U.S. clients. As we grow the sample size, we’ll no longer have this bias, and in turn be able to introduce geo-specific views of the data.

To my mind, the U.S. bias makes the difference in network usage even more striking. Many cities in America have abundant Wi-Fi locations. Why don’t Android owners use those hotspots?

Theories on why Android users don’t browse on Wi-Fi as much as iOS users

I have a couple of theories on why Android users don’t browse on Wi-Fi as much as iOS users:

As an aside, I believe income level disparity also helps explain the differences in app store success. There are many factors, but demographics need to be included when people compare the platforms.

Stating the obvious

It probably goes without saying, but if you’re on a Wi-Fi network, you probably have a faster connection and you’re usually not worried about the amount of data you use. Having a faster connection and no worries about your bill increases the likelihood you will browse the web more. The friction for browsing goes down tremendously when you’re on Wi-Fi.

All we have are theories

Even with Akamai’s data, we’re still just theorizing on what is going on. But I do believe that the data provides the first clue as to what might be happening. And if Google is smart, they’ll dig into this disparity further to see if there is something that can be done to increase the likelihood that Android users will connect to Wi-Fi networks. As outsiders, we can watch these metrics to see how well Google is adapting.

Finally, I’m pleased to have an opportunity to talk about Akamai IO’s data. It’s a great service that they’ve provided. And I know they have plans to make it even better. I suspect it took a lot of work to reassure people that it was ok to publish this information.

So thank you to those inside Akamai who championed it. And for the rest of us, let’s put this data to good use.
