Methodology
- Sample: the full Dataprovider.com index of 400M+ domains (390.1M primary hostnames). 55,422,534 primary hostnames have a detectable CMS; 54,540,299 of those have a known country.
- Detection: fingerprints in HTML source, generator tags, asset paths and rendered scripts. Counts filter primaryhostname = true.
- Known limitations: headless or heavily customized CMS installations may evade fingerprinting. W3Techs (top 10M sites) and Builtwith (top 1M) report higher shares for enterprise systems because their samples skew to high-traffic sites; our full-web sample makes the long tail of site builders visible.
- Coverage: Of the 390.1M primary hostnames in the index, 55,422,534 (14.2%) have a detectable CMS; the remaining 85.8% either run no CMS, are inactive or parked, or use a system our fingerprints do not yet detect.
Why CMS market-share numbers differ between sources
W3Techs reports WordPress at roughly 42% of all websites; this report measures 7.4% of all primary hostnames and 52.2% of CMS-detected sites. Neither is wrong - the samples differ. W3Techs measures the top ~10 million sites by traffic, where WordPress is strongest and parked or inactive domains are absent. Builtwith leans on the top 1 million, skewing further to enterprise platforms. Dataprovider.com measures the full index of 400M+ domains (390.1M primary hostnames), which includes the long tail of small sites where hosted builders like GoDaddy, Wix and Squarespace are far more common. When citing any CMS market-share figure, always state the sample alongside the percentage.
| Source | Sample | WordPress headline figure | Why it differs |
|---|---|---|---|
| Dataprovider.com (this report) | 390.1M primary hostnames - full index, including small and parked sites | 52.2% of CMS-detected sites; 7.4% of all primary hostnames | Full-web sample makes the long tail of site builders visible |
| W3Techs | Top ~10M websites by traffic (self-reported) | ≈42% of all websites (as published, May 2026) | Traffic-ranked sample excludes parked/small sites where builders dominate |
| Builtwith | Focus on top 1M websites by traffic | Reports absolute site counts rather than a single share figure | Enterprise-heavy sample; different detection and dedup approach |
