Platform mobile CWV pass rates, November 2025 CrUX Tech Report (SEJ analysis, Dec 2025)
Mobile CWV pass rate (Nov 2025), all-three-thresholds, per the HTTP Archive CrUX Technology Report, summarized by Search Engine Journal December 2025:
| CMS | Nov 2025 | Jun 2025 | YoY direction |
|---|---|---|---|
| Duda | 84.87% | 83.63% | ⬆ |
| Wix | 74.86% | 70.76% | ⬆ |
| Shopify | not in Nov SEJ breakout | 75.22% | (relatively flat) |
| Squarespace | 70.39% | 67.66% | ⬆ |
| Drupal | 63.27% | 59.07% | ⬆ |
| Joomla | 56.92% | – | ⬆ |
| WordPress | 46.28% | 43.44% | ⬆ but slowest gainer |
| Global (all origins) | ~48% | ~49% | (flat) |
Trend (Jun 2024 → Jul 2025 → Nov 2025):
- WordPress: 40% → 45% → 46.28%. Gain of ~+4 pp/year — half of Wix's +14 pp YoY and Duda's +11 pp YoY.
- 2025 Web Almanac quote (verbatim): "More extensible platforms improved less. WordPress and Drupal each gained around 4% year over year."
Confidence: Verified (CrUX is the authoritative public dataset; SEJ's SQL methodology is disclosed).
Reading the numbers correctly: a WordPress site is roughly 1.8× less likely to pass CWV than a Duda/Wix/Squarespace/Shopify site (mobile, Nov 2025). The closed-CMS lead is widening, not narrowing. See WordPress CWV gap causal decomposition (May 2026): ~40-50% hosting/TTFB, ~20-30% page builders, ~15-20% plugins, ~5-10% core, ~5-10% theme for why.
Supersedes the earlier June 2025 numbers in [[platform-cwv-pass-rates-june-2025]] (existing) — both kept for historical comparison.
