Overview
What the December 2025 Core Update did
The December 2025 Core Update closed out the year with a broad, index-wide reassessment of content quality. Industry reporting highlighted a noticeable lift for established brands in 'best of', 'best X for Y' and comparison-style queries — a continuation of Google's multi-year tilt toward recognisable, trusted sources for commercial research. As always with core updates, it was a holistic re-weighting rather than a targeted action.
Key points
What changed

Strengthen E-E-A-T: author expertise, real experience, and trust signals.
