These errors are received by all template owners who have not yet made their templates responsive by installing the viewport tag and using CSS3 media queries to create a fluid stylesheet for their mobile users connecting to your site via mobile phones or tablets.

Google now favors Mobile responsive sites over non-responsive sites in order to serve its users with fast loading and user friendly websites that may serve their queries faster.

Six Famous Mobile Usability Errors and their FIXES

  1. Flash usage
  • Fix: Mobile devices dont render flash based content therefore instead use HTML5 or gif to create animations
  1. Viewport not configured
  • Fix: Read below
  1. Fixed-width viewport
  • Fix: Never set content width to a fixed value instead use width=device-width to make content auto adjust itself to screen size.
  1. Content not sized to viewport
  • Fix: Use relative width and position Relative values for CSS elements. Use Overflow Hidden to avoid horizontal scrollbars
  1. Small font size
  • Fix: Set font-size such that it may be clearly visible to the mobile user. Best to do is to set it to 100%
  1. Touch elements too close
  • Fix: Use wider margins and padding values. Keep a distance between borders and the content.

Viewport not configured

Add the following meta tag to your blog

<meta content='width=device-width, initial-scale=1, maximum-scale=1' name='viewport'/>
