Surprising WordPress facts you probably did not know

Full guide

WordPress is one of those technologies that quietly shapes your daily life without ever asking for credit. You have almost certainly read a news article, bought a product or filled in a contact form on a WordPress site this week without knowing it. For something so widespread, it carries a surprising amount of history, personality and the odd eccentricity. Below we cut through the trivia and focus on the facts that genuinely matter, especially if you are weighing up WordPress for an Australian business website in 2026.

We have left out the unsourced numbers that float around older listicles and stuck to figures we can point you to, plus the cultural details that make the platform interesting. Think of this as the version your web developer would actually stand behind.

How much of the web really runs on WordPress?

This is the fact that surprises people most. WordPress is not just popular, it is dominant. According to W3Techs, which tracks technology usage across the web, WordPress powered about 41.5 percent of all websites and held roughly 59.3 percent of the content management system market as of June 2026. To put that in plain terms, when a site uses a known CMS, the odds are better than even that it is WordPress. No competitor comes close, which is exactly why the platform has such a deep pool of developers, themes and support behind it.

That scale is a practical advantage, not just a fun statistic. A platform this widely used means more talent who know it, more tested plugins, more documentation and a lower chance of being left stranded on niche software that nobody supports.

Here are the headline WordPress numbers at a glance, drawn from the sources referenced throughout this guide.

Where did WordPress come from?

WordPress launched in 2003 as a simple blogging tool, which makes it older than most of the social platforms people think of as internet veterans. It grew out of an earlier project and was shaped by a small open-source community that wanted publishing on the web to be easy and free. Over two decades it evolved from a blog engine into a full content management system capable of running everything from a one-page brochure site to a major online publication or store.

Crucially, it has stayed open source the whole way. The software from WordPress.org is free to download, use and modify, maintained by a global community of volunteers and companies. That open foundation is a big part of why it spread so far: nobody is locked into a single vendor, and the platform improves through contributions from thousands of people worldwide.

What is WordPress actually built on?

Under the bonnet, WordPress is written in PHP and stores your content in a MySQL database, a combination that runs reliably on almost any web host. Its real flexibility comes from two ideas: themes control how your site looks, and plugins add features such as contact forms, search engine optimisation tools, online stores and bookings. This separation is what lets a non-technical owner change a site dramatically without touching the core software.

That same plugin ecosystem is the platform greatest strength and its most common pitfall. Reputable, well-maintained plugins extend your site safely. Abandoned or poorly built ones are where most trouble starts, which leads neatly to the security question.

Is WordPress secure, or is that a myth?

WordPress has a reputation in some circles for being insecure, and it is worth setting the record straight. The core software is actively maintained, security focused and quick to patch issues. The overwhelming majority of real-world break-ins trace back to factors around the core, not the core itself: outdated plugins and themes, weak or reused passwords, and sites that simply never get updated.

The fix is unglamorous but effective. Keep WordPress, your theme and every plugin up to date, choose extensions that are popular and recently updated, use strong logins with two-factor authentication, and back the site up regularly. Do that, and WordPress is a perfectly safe foundation for a serious business website. Neglect it, and any platform would be vulnerable.

What are the quirky facts WordPress fans love?

Beyond the serious stuff, WordPress has genuine personality. Most major releases are named after a jazz musician, a tradition that reflects the founders love of jazz and gives each version a memorable identity during development. The project even has an official mascot, an endearing character named Wapuu who appears, often redrawn in local styles, at community events around the world, including here in Australia.

There is a thriving culture around it too: community-run meetups and conferences known as WordCamps, an enormous library of free and premium themes, and WooCommerce, the WordPress extension that turned the platform into one of the most common ways to run an online shop. These details matter because they point to something practical: a living, active community that keeps the platform supported and moving forward.

Is WordPress the right choice for your business?

For most Australian small and medium businesses, WordPress remains a strong default. It is flexible enough to grow with you, friendly to search engine optimisation, supported by a vast talent pool, and free of the licensing fees and lock-in that come with some closed platforms. It is especially well suited to content-driven sites, service businesses and online stores that want room to expand.

It is not the only option, and the best platform always depends on your goals, budget and how much you plan to grow. But the facts make the case clear: a free, open, endlessly extensible system that runs a large share of the entire web is a foundation worth taking seriously. The trick is building it well and maintaining it properly, which is exactly where good guidance pays off.
