Back in September, we wrote about the surge in usage of the mobile web. This month, a startling survey from GSMA reveals that 25% of the UK population went online via mobile during last December.

Astonishingly, almost half the time online was spent at one site: Facebook (the next popular domain, Google, is not as much of a surprise). It seems that those with a real Facebook habit cannot bear to put down its networking and socializing capabilities, even while they are out and about.

For you, the business owner, this points to one thing: you need to keep your Facebook presence fresh, current and useful. After all, you know what they say in online marketing: don’t wait for the customers to come to you. These days, you have to go to where they already are – and that, it seems, overwhelmingly, is Facebook.
