As more and more people use their smartphone to access the web, it is getting increasingly important to have a website that will work well when viewed on a phone. This can be accomplished by building a mobile version of your website. Some things to take into consideration is load time, user experience, layout and usability.
Load Time
With the introduction of 4G, smartphone connections are getting faster and faster, but a majority of smartphone are still slower than a connection from a desktop or laptop. Users also are less likely to wait when accessing the web from a smartphone.
User Experience
Users usually have a different need and expectation when accessing your site form a smartphone. They are looking for fast important information such as contact information, location and services.
Layout
The screen on a phone is obviously much smaller than a computer, and this poses some special problems. While technically most website can be displayed on a smartphone, they will likely be almost impossible to use on a small phone screen.
Usability
The way you interface with a site on a smartphone is different from a desktop. There is no mouse or separate keyboard, and certain types of content will not display well on a phone. All this needs to be considered when building an effective mobile website. There are also special functions that are available on a phone, such as a 'click to call' button.
