With the increasing usage of web on mobile devices, the need to understand the end-users has emerged with prime importance. End-users’ experience of web on desktop and mobile devices is almost entirely different and even these users has a different kind of ‘mental model’. Interface or navigation designs that works great on desktop may not work in the same way on mobile web as it is.

A usable navigation design improves the end-users experience and makes sure that users don’t leave the website due to frustration as they are not able to use your website on their mobile device.

While designing websites specifically for mobile devices, there are several factors which you will have to consider. In this article, we will discuss particularly about “navigation design for mobile websites”. You can read more about Usability Factors for mobile web as well as Design Factors for mobile web.

Here, we will discuss some important aspects of navigation design for mobile websites:

1.Provide only minimal navigation at the top of the page:
Only basic navigation to help users enhance the experience by reducing clutter for these relatively small screens. Core links upfront also help users to navigate across the application easily without getting much frustrated. In case of footer links, provide very few (2-3) and only if it’s really essential and helps users.

Provide only minimal navigation.

2. Balanced Site Structure:
Unlike desktop-based browsers, mobile web browsers has too many limitations like screen size, hardware’s processing capabilities, memory, etc. Scrolling too much could be painful for the users on such devices. So, the information architecture will need to take care of this balance between that will help end-users to reach the desired content with minimal links.

Inessential links or steps added to get the desired content make users frustrated and they simple stop using the site.

3.  Consistent Navigation Mechanism:
The way users navigation on mobile devices is not as easy as pointing devices like mouse on a desktop and they have to rely on joysticks / 4-way navigation or keypad. In such a case, using a consistent navigation method helps a lot.

A “drill-down” navigation mechanism in such interface can help end-users, as it is based on the major headings that take you inside it based on your preferences. For example, someone who wants to see what’s available in movies or music can be directed to the same using main heading link as “entertainment”. Also, we should make sure that links that takes him to main homepage or category homepage are available, e.g. home, entertainment, up, back to top.

Consistent Navigation Mechanism

Make sure you keep these links minimal required and steps to get the desired content also very minimal, as users may not be interested in going for more retrievals or clicks to get the content he / she is looking for. Also, some form of breadcrumbs can help them to track their trail as well as to go back easily.

4. Device-based Access Keys:
Unlike traditional desktop computing, mobile device is not capable of relatively easy-to-use point device (but is bit easier in smart-phones with some point device like stylus). In such a case, we should use the built-in capabilities of the keys built on the device, which are keyboard shortcuts for a mobile device. Users can press a number on the keyboard to go to a link associated with.

Also, make sure that same access key assigned a link is used across the application for the same link.

5. Description for the link:
Provide information related to a link. For example, if a link is directed to a file which may not be supported by the end-users device, it may be frustrating for him as he isn’t ware of the kind of file type is linked with that particular link. Handsets which don’t support videos etc. may show undesired response and may frustrate the end-user.

6. Do not Use Image Maps-based navigation:
Even though it’s an effective way to navigate by using client or server-side image maps, most of the mobile devices don’t support them. Also, usage of images as navigation should be avoided as end-users with information-seeking behavior tend to disable loading images and your navigation may go completely invisible for the end-user, as browsing websites on mobile devices do involve data usage charges to the end-users and they may be simply not interested in viewing those images as they have to pay for it.
