WordPress is by far the most popular content management system for building websites.

Looking at the statistics provided by W3Techs shows that WordPress is used by 14.7% of the world’s top one million websites and over 54.5% of all those websites that use a CMS.

It is interesting to note that the next two most popular CMSs are both also opens source; Joomla with a 10% market share and Drupal with 6.2%.

The same sources provides figures for the use of CMSs by websites in the top one million that have a .uk top level domain. The dominance of WordPress is repeated here with a market share of 48.9%.

A similar pattern can be found in the CMS usage statistics provided by BuiltWith who currently reckon that WordPress is the most popular CMS used by Websites in the top million websites with a share of 63.19%.

If you want to include favicons as part of your WordPress theme then you should add the following code into the header of your pages. The code includes a tag for standard favicons as used by most web browsers. It also includes a tag used by Apple devices such as iPad and iPhone.

Code for adding favicons to your WordPress theme:

<link rel="shortcut icon" href="<?php bloginfo('template_directory'); ?>/favicon.ico" />
<link rel="apple-touch-icon" href="<?php bloginfo('template_directory'); ?>/icon.png" />

You then need to create a favicon.ico file and a icon.png image file and add these to the template folder.

The icon file should be an image 16×16 pixels.

The .png file for Apple devices should be 57×57 pixels (although I have seen some suggestions that 114×114 is best for later Apple products). Don’t worry about adding the curves and shiny effects that you see on the Apple devices, these will be added automatically.
