CMS
A CMS (content management system) is software that lets you create, edit, and publish website content without programming. You work in a visual interface where you can change text, images, and page structure, while the system takes care of the technical side in the background. The best-known CMS platforms include WordPress, Webflow, Shopify, and Drupal.
A CMS is a basic building block of almost every modern website. Your choice affects publishing speed, security, scalability, and running costs:
- More than 70% of websites now use a CMS. According to W3Techs, which continuously tracks technologies on the top 10 million websites in the Tranco ranking, only 28.6% of websites ran without an identifiable CMS in February 2026—down from 68.2% in 2013 (W3Techs – Market share trends for CMS, 2026)
- WordPress dominates the market, but competition is growing. W3Techs reports that WordPress powers 42.8% of all websites and holds a 60% share among sites with an identified CMS (February 2026). Shopify is second with 5.2% and Wix third with 4.2%. However, SaaS platforms like Wix are growing at more than 32% year over year (W3Techs – WordPress Usage Statistics, 2026; Search Engine Journal – CMS Market Share Trends, 2025)
- The CMS market is growing fast. Grand View Research estimates the global CMS software market at USD 34.94 billion in 2025, with a projected CAGR of 10.6% through 2033 (Grand View Research – Content Management Software Market, 2025)
- Headless CMS is on the rise. The headless CMS market is growing at a CAGR of more than 22% and, according to Market Research Future, will reach USD 3.04 billion by 2030. Gartner predicts that by 2026, 70% of organizations will require composable DXP technology instead of monolithic solutions (Market Research Future – Headless CMS Software Market, 2024; Gartner – Predicts 2024: Composable DXP)
FAQ
What's the difference between a traditional and a headless CMS?
A traditional (monolithic) CMS like WordPress combines content management with the presentation layer—content is tightly tied to a specific theme. A headless CMS, on the other hand, separates content from the front end and delivers it via API to any platform (web, mobile, kiosk). According to a 2025 Storyblok survey, 73% of companies are already implementing headless architecture in their tech stack, and 69% of respondents report faster time to market (Storyblok – CMS Usage Statistics & Trends, 2025).
Why not just stick with WordPress if most websites use it?
WordPress is versatile and has a huge plugin ecosystem, but it comes with trade-offs. It needs regular updates to its core, plugins, and themes, it's a frequent target of security attacks, and without optimization its performance degrades quickly. Modern platforms like Webflow offer a visual editor, hosting, SSL, and a CDN in one package, with no need to manage dozens of plugins. BuiltWith data from an analysis of the top 1 million websites shows that hosted solutions like Webflow and Wix are growing steadily, while WordPress's share among CMS sites has declined for the first time, from 65.2% (2022) to about 60% (BuiltWith – CMS Web Usage Distribution, 2025).
Can a CMS help with SEO?
Yes, a good CMS has a major impact on SEO. It makes it easy to edit meta tags, generate a clean URL structure, create XML sitemaps, and manage redirects. Page speed—which the CMS directly affects—is a confirmed Google ranking factor. An analysis of 900,000+ mobile pages by Google and Deloitte found that a 0.1-second improvement in load time increases e-commerce conversions by 8.4% (Think with Google / Deloitte – Mobile Speed, 2020).
