Since its launch in 2003, WordPress has become the most popular content management system (CMS) on the web. It’s running millions of websites: over 20% of every websites on the entire Internet, and almost half of all websites that use a CMS.

With all that success, you’d think that Automattic, the company behind WordPress, would be raking in the dough. But founder Matt Mullenweg is no billionaire. In fact, one big reason for WordPress’ ubiquity is that it’s free to use.

But even though WordPress itself is free, the economy that’s arisen around WordPress has grown just as fast as the software’s popularity, bringing in millions of dollars every year.

WordPress theme design, plugin development, consulting, hosting, site maintenance, and blogging are just a few of the services that have developed around WordPress. The WordPress economy is even booming offline, with over a thousand book published on the topic. Thousands of people around the world earn a living with work exclusively related to WordPress.

In this booming WordPress economy, it may seem that there’s no room for more people to cash in. Today, for instance, the WordPress theme shop market is competitive and hard to break into, unlike a few years ago when you could expect to see success immediately.

Still, the industry is expected to continue its growth, and with it the demand for services. The latest version of WordPress, 3.9, has already been downloaded over 40 million times since its release in April 2014, and thousands of new WordPress websites are being launched every day.

In such a booming economy, there’s also a growing demand for services. Though generalists will find it hard to stand out and differentiate themselves from competitors, choosing a niche to specialize in is a good way to stand out and offer unique value.
