Read this very interesting article stating that 25% of all websites are now on WordPress.
World Wide Web Technology Surveys (W3Techs) announces that a recent survey of websites has shown that WordPress, the popular open source publishing platform, is being used in over 25 percent of all websites. That’s not just 25 percent of all those using a service but all websites.
In second and third place are Joomla and Drupal, platforms that power less than 5 percent of the market. Counting all the others, that leaves 57 percent of the market that doesn’t use any service at all.
Matt Mullenway, founder and CEO of Automattic, the company that developed WordPress, states in his blog, MA.TT:
The big opportunity is still the 57 percent of websites that don’t use any identifiable CMS yet, and that’s where I think there is still a ton of growth for us (and I’m also rooting for all the other open source CMSes).”
Matthias Gelbmann of W3Techs is quoted in Marketingland.com explaining:
We have indicators that WordPress is likely to grow even further. In October, 29.5 percent of new sites used WordPress, and new sites usually show where the whole market is heading.”
