Space Efficiency

You see some mobile sites try to cram in way too much info, and it turns into a crowded mess. The trick is to keep things simple. Prioritize what actually matters and don’t overload the layout.

Enable Touch Interactions

You have to think differently on a mobile shopping website. Swiping and tapping feels nothing like pointing and clicking with a mouse. Build your interface so it makes sense for fingers, not just clicks.

Minimize the Text Inputs 

Typing on a phone feels clumsy in mobile commerce solutions. Skip text fields when you can. If you need users to type something, use autocomplete or auto-suggest tools to make it as painless as possible.
