What is a CMS, and why WordPress is still the most used

studioweb10 TeamSeptember 5, 20263 min read

You’ve surely heard of WordPress. But do you really know what it is and why more than 500 million websites use it? The answer has to do with freedom, control and ease of use — and understanding it is the first step before choosing the platform for your own project.

What a CMS is

A CMS, or Content Management System, is software that lets you create, manage and modify digital content on a website without needing to know how to code. It’s like having a text editor for the internet: you publish posts, change images, update products, all from a control panel.

Without a CMS, every change to your site would require a programmer to write code. With one, you manage it yourself, saving time and money day to day.

WordPress: the undisputed giant

WordPress isn’t just a CMS: it’s the one that dominates the market. More than 43% of all websites in the world run on WordPress, and if you look only at the segment of sites that use a known CMS, its share shoots up to 60-61%. The second most used platform, Shopify, stays at 6.7%.

Why is it still the king? A combination of factors makes it a very hard option to beat:

Ease of use and a massive ecosystem. Its dashboard is intuitive even for people who aren’t tech experts, and its real strength is the ecosystem: more than 60,000 plugins and more than 8,000 themes. Online store, forum or booking system — there’s probably already a plugin for that.
Freedom and total control of content. Unlike closed platforms such as Wix or Shopify, you own your data and your code. You can host your site wherever you want and take all the content to any server whenever you need to.
The king of SEO. It offers detailed control over key ranking elements, such as tags and URL structure, and specialized plugins (Yoast SEO, Rank Math) that guide optimization step by step — ideal for projects where content and organic traffic are the priority.
Constant adaptation. It incorporated the Gutenberg block editor in response to competitors’ drag-and-drop builders, and is already integrating AI assistants for content creation.

The challenges that aren’t talked about as much

Not everything is perfect. Being the most popular platform comes at a price: it’s the most attractive target for cyberattacks, so keeping it secure and up to date is a constant responsibility. A lack of maintenance can slow the site down and open vulnerabilities, and dependence on third-party plugins is a double-edged sword — a poorly optimized plugin can drag down the performance of the whole site.

On top of that, competition is tightening: platforms like Wix and Shopify have improved and are gaining ground with more closed but easy-to-use offerings, and in recent months WordPress showed a slight drop in its market share. Even so, it’s still, by far, the most popular and versatile option on the market.

A CMS doesn’t choose your business for you — the right question isn’t which one is “the best”, but which one you can sustain with the team and budget you have today.

WordPress dominates for a reason: it solves a huge range of use cases well, from a personal blog to a complex corporate site. But “the most used” doesn’t always mean “the right one for your project” — it’s worth evaluating maintenance, security and the available team before building on any platform.

Frequently asked questions

Everything you need to know about a CMS and WordPress

01What's the difference between WordPress.org and WordPress.com?

WordPress.org is the self-hosted version: you download the software, choose your own hosting and have total control over your site, being able to install any plugin or theme. It's the option most professionals recommend. WordPress.com is a hosting service that uses the same software, but with plans that limit customization and the available features.

02Is WordPress only for blogs?

No. Although it started as a system for blogs, today it's a general-purpose content management tool. You can build practically any type of site: online stores with WooCommerce, portfolios, digital magazines, corporate sites, forums, directories and more — its possibilities are almost unlimited.

03Is WordPress secure?

The WordPress core is secure and is constantly updated. The main risk is usually third-party plugins or themes that aren't kept up to date. Following good practices — updating everything, using strong passwords and reliable security plugins — it's a very dependable platform.

04What alternatives to WordPress exist?

Several, each with its strengths. Drupal is powerful and secure, ideal for complex, large-scale projects, although it demands advanced technical knowledge. Joomla is an intermediate option, with good permission management and native multilingual support, but a smaller ecosystem. For online stores, Shopify is a serious competitor: an all-in-one solution that's very easy to use, but with less freedom and more commissions.

05Why is WordPress still the most used CMS?

Because it offers the best balance between ease of use, flexibility and control. Its huge ecosystem of plugins and themes lets you build almost anything without starting from scratch, and its massive community guarantees support for almost any problem. It's a platform that adapts from a personal blog to a large corporate site.
