Google December 2025 Core Update: What Happened to Rankings
December 11, 2025 (9:25 AM PST) — Google started rolling out the December 2025 core update. This is a broad algorithm update, not a penalty system.

Early Traffic Patterns
Across multiple sites and audits, early patterns look like this:
| Content Type | Change | Observation |
|---|---|---|
| Generic AI content | −70% to −85% | No first-hand insight |
| Affiliate-heavy pages | −50% to −65% | Ad-first layouts |
| Expert-written content | +40% to +70% | Clear author trust |
| Tested reviews | +30% to +45% | Proof + experience |
If your WordPress site lacks visible experience or authorship, drops between 15–60% are common.
