Further to my previous blog post on Why You Need a Mobile Website, mobile traffic is increasing exponentially for iPad, iPhone and Android. Blackberry traffic is also increasing but that is just because most companies have not adopted Apple products. But once they do, Blackberry will no longer be relevant because its poor user experience.
When someone is browsing your mobile website on their smartphone, they are expecting an entirely different experience than if they were on a laptop. Mobile visitors are usually looking for contact information or they are returning visitors who have visited your website already on laptop and are coming back to get information seen previously. Most of them are not interested in casual browsing due to slower page loading times and much smaller screen sizes.
