It feels like a whirlwind every time Google releases a core update, and the December 2025 core update was no different. I’m thrilled to share that this is the third core update of 2025, taking a little over 18 days to roll out completely. It kicked off on December 11 and concluded on December 29. According to Google, this update aims to enhance the visibility of relevant and satisfying content across all types of sites.
Reflecting on the timeline, this update came five months after the June 2025 core update, which itself followed the March 2025 update. It’s interesting how Google spaces these updates throughout the year, creating waves of anticipation and speculation in the SEO community.
In the coming days, I’m eager to delve into data to understand how this update has influenced rankings and share that insight with you via Search Engine Land.
