Google December 2025 Core Update - Rolling Out!

The latest update in the Google Search Status Dashboard showcases that December 2025 core update is rolling out. This will affect the ranking of global sites centralizing EEAT principles.

Google said this December 2025 core update is a regular update, and it will release more updates from time to time. This update simply targets all types of content and ensures people-first, meaningful, and reliable content appears to users on Google’s search result pages based on their intent.

Insight: Content improvement will have a big impact on website ranking.

The post was released officially from the Google Search Central account on the X platform at 10:57 PM, Dec 11, 2025.

This post states:

“Today we released the December 2025 core update. We’ll update our ranking release history when the rollout is complete.”

This is a regular core update and may take up to 3 weeks to complete full rollout. It was launched on 11 Dec 2025 at 09:25 PST. But 2 days before this announcement, Google made slight modification to its core updates documentation.

Google added more information about the core update. The updated documentation now states:

“However, you don’t necessarily have to wait for a major core update to see the effect of your improvements. We’re continually making updates to our search algorithms, including smaller core updates. These updates are not announced because they aren’t widely noticeable, but they are another way that your content can see a rise in position (if you’ve made improvements).”

The additional document states that Google is continually making updates to its search algorithm. These updates also include smaller core updates that are not officially announced. It means all content creators don’t have to wait for a major core update to see the effect of the improvement. If improvement is made in content, the impact will appear in the web position.

Since the announcement of December 2025 core update, fluctuations in web ranking have been observed. If your website’s position has also been affected, this may be the reason.

During the rollout, you may see more changes in your website's ranking on SERPs. However, if you are continuously working to optimize the site & content, then you may also observe a drop in web ranking positions. Wait to complete the rollout and make adjustments based on Google’s guidance.

There is one more crucial thing that Google said. It also launches a small update without announcement, so website owners need to keep updating their content and site constantly to remain compliant with Google’s algorithm and improve search visibility.

This is a big core update for December 2025. With its launch, a significant discussion has been taking place across the SEO community. Here are some comments from SEO professionals about the core update announcement on WebmasterWorld and Black Hat World platform.

• So I can write off November. News site: 30 percent fewer visitors, 60 percent less advertising revenue, and we'd rather not talk about the ranking: chaos... The shop: sales have declined slightly (-4 percent), which is a normal fluctuation, but here too, the ranking is in complete chaos... I'm curious to see how December develops, but I'm afraid it won't be good…
• Where is the traffic? What is happening ?
• They will see when they don't have any sales. ROI must be the lowest in the entire internet history.
• The Christmas and New Year celebration with Google Core. Many of the bloggers and website owners are terribly watching these Core changes
• My keyword rankings are fluctuating a lot right now. A site that was on the first page dropped to the fifth page, but when I search again it shows up on the first page. The rankings are also different between mobile and PC. Why is this happening? When will it stabilize? Has a penalty been applied?
• I’m noticing some changes already. A few well-optimized pages went up, and some older ones dropped a little. It looks like Google is focusing more on content quality and intent match. Still early in the rollout, so things may shift more in the next few weeks.

Following the rollout of Google’s core update December 2025, website owners globally have been monitoring its impact on SERPs. The given graph report illustrates significant ranking fluctuation after the core update was released.

Once this core update finishes rolling out, Google will notify us.
