Google December 2025 Core Update Rollout Completed

Google has officially completed its December 2025 core update, the third and likely final core update of the year. The rollout began on December 11, 2025, and took 18 days to complete, ending on December 29, 2025.

According to Google, this is a “regular update designed to better surface relevant, satisfying content for searchers from all types of sites.”

Timeline of 2025 Core Updates

• March 2025 Core Update: Mar 13 – Mar 27
• June 2025 Core Update: Jun 30 – Jul 17
• December 2025 Core Update: Dec 11 – Dec 29

This December update followed a five-month gap since the June 2025 update and months after the March update.

What We Observed

Initial signs of the update’s impact appeared within a few days of the announcement, around December 13, 2025, followed by a spike in ranking volatility on December 20. As is typical with core updates:

• Some sites saw significant ranking gains
• Some sites experienced declines in visibility
• Many sites had little to no change

Experts, including Glenn Gabe, have shared video insights on the December core update for those looking to analyze the impact further.

What to Do If Your Site Was Affected

Google has not issued any specific guidance for this update. However, past advice still applies:

• No quick fixes: Negative ranking changes do not necessarily indicate a problem with your site.
• Focus on helpful content: Continue creating content meant for people, not search engines.
• Recovery may take time: Some improvement can happen before the next core update, but major changes usually follow another update.
