You've heard it before: mobile usage on the web is growing. But since Click Rain's unofficial motto is, "If we can't measure it, we don't do it," I felt some measurement was in order. I needed proof.
So I decided to scour our logs to determine how mobile usage across our sites has grown over the past year. And my findings not only backed up my claim, but provided me with new insight on how we can help our clients succeed online.
Overall Stats
Mobile* usage nearly doubled on our sites in 2012. In January, 8.5% of visits to the sites we work with came from mobile devices. In December, that number rose to 15.8%.

Sites with Mobile Visits
In the final quarter of 2012, a large chunk of our sites (83%) had at least one visit out of every 10 come from a mobile device. And nearly a quarter of our sites had at least one visit out of every five come from a mobile device. This is up from the same quarter in 2011, in which 72% of our sites did not receive even one out of every 10 visits via a mobile device.
The difference is not just apparent but imperative:
Summary
Mobile usage is increasing, and shows no sign of stopping. With 10-20% of your potential customers visiting from a mobile device, can you afford to ignore the mobile segment?
Isn't it time to provide all of your potential customers with a top-notch experience?
