People always have their mobile phones with them. This means that they will access a mobile site on many occasions and from many locations: on the train, in the garden, at the airport, at the bus stop, walking down the street, at a football match, at a concert, whilst out shopping. They therefore have every right to expect instant and compelling content on mobile sites.

Sometimes mobile sites will just be a subset of the main web site, but they are much better when offering interesting, instant content and location-based services. Even the latest mobile phones have limited screen space, that can only handle small amounts of information at a time. Mobile sites are therefore, best when designed specifically for mobiles and handheld devices, rather than the mobile trying to reshape and compress the original web site; rendering it to fit the smaller dimensions.

The difference between these two types of site is vast: one, the specifically designed, presents a professional user-friendly site that is easy to read. The other offers a sometimes confusing, unordered site, which often doesn't even resemble the original web site.

Mobile sites can be accessed by either typing in a URL, texting a short code to a phone number to receive a URL in return, or by scanning a 2D Barcode.
