WordPress Still Dominates Open Source CMS Market in 2011

WordPress is the most used CMS, Concrete5 is the biggest riser

The water&stone Agency published its annual Open Source CMS Market Share Report, the most comprehensive study about open source CMS usage amongst web professionals.

The report comprises statistical usage data about the 20 most used CMSs around the web.

As in the previous years, the top three remained the same, with WordPress on top in most categories, followed by Joomla and Drupal.

Water&stone analyzed a CMS's rate of adoption (download numbers, live installations, third party support) and brand strength (search engine visibility, reputation, mindshare, project popularity).

Even if it tops the ranking in weekly downloads with almost 645,000, WordPress is down 34.4%  from its 2010 numbers, 980,000 per week.

But just as last year, if we total all other CMS weekly download averages, they still can't surpass WordPress, barely reaching 185,000, all combined.

The biggest jump for download numbers in 2011 was registered by Concrete5, with a 517% rise, while the biggest drop was recorded by CMSMadeSimple, with -73.3%.

WordPress is also used by most sites in the Alexa Top 1 Million, being installed on 53.6% of all sites. Joomla comes in a distant second with 9.6%, followed by Drupal with 6.4%.

Other categories in which WordPress dominates include: the number of printed books, total freelance jobs it provides for professionals (statistics via renowned marketplaces Elance and Guru), project site ranking in Alexa, Google PageRank (tied with Plone, Drupal and Joomla for a PR9), brand familiarity to regular users, and conversion rate for trial users.

Categories in which it didn't come first, but ranked favorably include: inbound links to project site (Joomla), user survey specific product preference (Concrete5), brand loyalty (Concrete5), Facebook mentions (Joomla), Twitter popularity (Drupal), blogosphere popularity (Drupal & Joomla tied for first), social bookmarked links (Drupal) and search engine query volume (Joomla).

For this study, 35 CMSs were considered, with 20 of them making the final report. The other CMSs in this study, considered major players in the CMS market, include: Alfresco WCM, DotNetNuke, e107, eZ Publish, Liferay, MODx, Movable Type, OpenCms, SilverStripe, TextPattern, Tiki Wiki CMS Groupware, TYPO3, Umbraco and XOOPS.

Besides its own user survey, water&stone pulled statistical data from several renowned and reliable web sources, including Alexa, Amazon, BuiltWith, Elance, Guru and W3Techs.
