What Makes a Website Mobile-Friendly?

Over time, many statistics have been formulated to analyze websites for their “mobile-friendliness.” The basis of these statistics ranges from the use of mobile real estate to the themes of design that a website developer selects for use. Google has done a great deal in this analysis and now provide developers with clearly defined in the Google guidelines on mobile-friendly web development.

The first focus of a mobile-friendly website will come from the visitors of your site. The visual presentation of information is a crucial aspect of how your visitor judges the website. The key areas of focus in the visual presentation include:

Responsive Design

The responsiveness of a site forms the basis for its mobile-friendliness. Responsive design of a website ensures that the content of that website will be resized and rearranged based on the size of the screen it is displayed on. A mobile responsive page, for example, will turn a vertically displayed menu to a horizontal display to enhance the website appearance. Unnecessary graphics such as images, GIFs, and videos may also be removed for better content presentation.

Readable Fonts

The focus for how information is presented in most web pages tends to lie on text representation, with images, videos, and audio enhancing the information that is in the text. The mobile-friendly website focuses on readability of text and usually have their content in sans-serif which is readable on screens of various types and sizes. Font sizes should also be carefully considered as it will affect how readable your paragraphs will be to the user. A standard size for most platforms your website could be viewed in is 16px.

Proper Text Formatting

Long blocks of paragraphs may appear neat on a desktop, but the length on smaller screens may look like too much information and scare the reader. Shorter and more precise paragraphs should be employed for a mobile responsive design. Keep the sentences short and direct, and apply bulleting and numbering where relevant.

Optimized Media Display

Information that is represented in videos and images must be sized in a way that doesn’t need scrolling or resizing of a page to view.

Accurate adaptability can be enhanced by always using the viewport meta tag for your graphical elements.
