The are a number of different open source content management
systems – 
otherwise known as CMS that are used to manage website content. While it is not always a given that the most popular system is the best, in the case of WordPress CMS, it is not hard to argue that it is.
Giant companies like Wall Street Journal, CNN and NY Times use WordPress CMS to develop and manage their blogs and websites. From conceiving, editing, publishing to indexing content – everything can be done with such ease. These are the top reasons why WordPress is the undisputed leader in CMS.
Free and flexible
For start-ups that want to keep costs to a minimum, you’d be surprised to learn that WordPress CMS is actually free to use – this despite its many powerful features. Whether you want to run a personal website or a commercial one – everything is gratis. Of course, you still have to take into account the domain and hosting charges. On top of that, it is also flexible – so you can customise it to fit your needs. It can be as simple as you want or as complex as your business requires.
Ease of use
You don’t have to be a nuclear scientist to use WordPress CMS, because many of the features have been designed with ordinary users in mind. For example, for every post that you create, you can easily assign different categories to it. Though powerful in nature, WordPress is known for its ease of use and simplicity. Getting things done will require less effort.
Extensive plug-ins
Thanks to the extensive number of available plug-ins for WordPress, gone are the days where you would have to pay developers to create a single application to run on the website. Everything you could possibly want out of a website can be easily had – most for free. There are thousands of third-party plugins that you can download, install and use. From Twitter tools, RSS feeds, Search Engine Optimisation (SEO), to Google XML sitemap generator – everything is at your disposal.
Regular updates mean more security
Choosing WordPress CMS means making the right option of keeping your website clean from bugs, malwares and other security issues that usually plague the World Wide Web. WordPress is known for updating its system regularly; thus keeping the system, and ultimately the content and data on your website, secured.
Supported by developers
If there’s ever an application that you can’t find on the long list of plug-ins available freely for the platform, you can always outsource it to the thousands of developers that support WordPress. Being the most popular content management system on the planet does have its perks.
