LONDON, January 3, 2013 /PRNewswire/ -- Research Finds Even the Top Decile of FTSE-100 Mobile Websites are Haphazard UK Businesses are way Behind Their American Competitors and Losing Out as a Result Despite the rapid take-up of smartphone and tablet mobile devices, a surge in m-commerce and the introduction of 4G, FTSE-100 companies are not mobile-ready and as a result are wasting millions of pounds on internet advertising by sending consumers to sites that do not work as users expect them to. The fix is easy. A comprehensive study into UK mobile business performance, by Incentivated, reveals a chasm between consumer behaviour and Britain's top companies. Incentivated employed the kind of rigour that consumers do when voting with their thumbs, and the reason why leading US brands are dominating the digital landscape as it mobilises. UK and Europe no longer lead the way in mobile marketing. The Americans follow the dollars and people are buying through mobile. Each FTSE-100 company website was analysed and scored for mobile readiness based on three objective criteria as well as two subjective ones: whether a mobile search is automatically detected and directed to a mobile site (or served a meaningful responsive design); whether the page size is small enough to load quickly on a 2.5G or 3G network (i.e. an element of server-side responsiveness or 'RESS' to reduce payload); and whether the site is optimised to work across multiple mobile platforms such as Android, Windows and Blackberry rather than just iPhone alone. (Minor UX issues, like hiding the URL bar to release more space for content, have been ignored in this analysis.) The subjective criteria included: whether the site contained useful content or was just a blog or similar short-form content such as a list of links to un-optimised desktop content, and whether there was branding in place. Mobile real estate is just as valuable as anything else and some businesses have shown that a small screen-size is no limit to creativity.
