WordPress and CMS Usage Statistics

The number people quote incorrectly

WordPress had a 64.3% share of CMS-driven mobile sites in the 2025 Web Almanac CMS analysis. The qualifying words matter. This is not a claim that WordPress powers 64.3% of all websites. The same report says a CMS was detected on more than 54% of observed sites. Mixing those denominators would exaggerate WordPress's share of the entire web.

The comparison is useful because it shows scale within the detected CMS market: Shopify accounted for 7.3%, Wix 5.2%, and Squarespace 2.9% of CMS-driven mobile sites in the same analysis. These percentages do not add to 100%; other platforms account for the remainder. The chapter also notes that Shopify was classified under CMS in this edition, which matters when comparing with earlier years.

What the data can tell a site owner

Adoption tells you about an ecosystem, not which platform is best for your project. A large installed base can mean more themes, developers, documentation, and integrations. It can also mean a wider range of hosting setups and site quality. The platform alone does not determine whether a site loads quickly, is accessible, or converts visitors.

WordPress also represented roughly 58% of detected CMS usage among the top 10,000 sites in the Almanac's rank analysis. That is a different population from the overall mobile CMS chart above. Comparing the two can be interesting, but it is not evidence that WordPress causes higher traffic. Popular sites choose platforms for many reasons, and ranking tiers can change how technologies are detected.

How the figures were produced

These are observations from the HTTP Archive's 2025 crawl and technology detection, not a census of every live website. The Web Almanac methodology describes the July 2025 dataset and its limits. Platform fingerprints can be obscured by a custom frontend or change when detection rules change. The figures are a snapshot of detectable usage in that dataset.

When citing a number from this page, state the platform, device, year, and denominator together. “WordPress had 64.3% of detected CMS usage on mobile sites in the 2025 Web Almanac” is defensible. “WordPress runs 64.3% of the internet” is not.
