Google December 2025 Core Update Launched: Search Changes

Last Updated on: December 16, 2025 by

Google shakes up the search world again. The tech giant launches the Google December core update, its third core algorithm refresh of 2025. This broad change aims to deliver better, more relevant results to users everywhere. Google started the rollout on December 11, 2025, and experts expect big ranking shifts for websites over the coming weeks.

The Google December core update improves how the search engine evaluates content quality across the web. It rewards helpful, reliable pages and pushes down less useful ones. Website owners and SEO pros already report volatility in rankings as the update spreads globally.

Key Details About The Google December Core Update 2025

Google December 2025 Core Update

Google shares clear facts about this major refresh:

  • Start date: The rollout begins on December 11, 2025, at 9:25 a.m. Pacific Time.
  • Duration: It takes up to three weeks to fully complete.
  • Type of update: This broad core change affects overall ranking systems, not specific spam or factors.
  • 2025 timeline: It follows the March update (March 13-27) and June update (June 30-July 17), plus an August spam update.
  • Ongoing improvements: Google runs smaller, unannounced core tweaks between big ones, so sites see changes anytime after fixes.

If your site drops in rankings, Google stresses it often means no violation, just a reassessment against better content. Focus on creating high-quality, user-first pages with strong E-E-A-T (experience, expertise, authoritativeness, trustworthiness).
