"So what exactly are customers looking for from a mobile-friendly website? Here are three points Google highlights its survey:

1. Fast loading. That means 5 seconds or less.
2. Mobile-friendly features. These can include large buttons, easy search and limited scrolling and pinching.
3. Quick access to business information. Display info like directions, contact numbers, product information and how to make a purchase right up front so it's easy to read on a smartphone or tablet."
