Google nearly missed its year-end deadline with its latest core update. The technology giant activated its principal update on December 11, along with the prediction that it would take approximately three weeks to complete. Had this timeframe been followed strictly, we would be delivering this news on the first day of 2026. However, the update was ultimately rolled out in 18 days, concluding on December 29.
Through its LinkedIn account, Google explained that this core update is “a regular update designed to better surface relevant, satisfying content for searchers from all types of sites.”
According to benchmark indicators such as the Sensor from Semrush, the volatility in search results produced by this update has been limited, with the most unstable period coinciding with the initiation of the core update:

Google’s core updates, or principal updates, are significant modifications to the algorithms and search systems that aim to improve the relevance and quality of results presented to users. In 2025, Google has executed a total of three core updates (one fewer than in 2024):
With the official conclusion of the December 2025 core update, we are entering a period of analysis and cautious calm. It is essential to understand that, although these updates often disrupt the rankings landscape, Google does not provide a specific “to-do list” for recovering lost positions. There is no magical “fix” button; the official recommendation remains: prioritize the creation of useful, relevant, and high-quality content from both a technical and human perspective.
The first practical step is to analyze your rankings using actual data. Make use of tools such as Google Search Console to break down how your strategic keywords have shifted and, most importantly, identify if your main traffic sources have been harmed or strengthened. Compare this data with your internal analytics to understand the real business impact and… cross your fingers.
Additionally, despite the increasing presence of AI Overviews and AI Mode in search results, the overarching philosophy does not change: providing value to the user remains your best lifeline. If your site offers clear answers and a unique value proposition, you will be in the best position to coexist with artificial intelligence and benefit from new search habits.
Finally, remember that 2026 is a new year. While it is possible to see minor recoveries between updates, Google cautions that the most substantial ranking adjustments generally consolidate after the next major update. Therefore, if your website has been affected now, your goal for a full recovery should be set for the first core update of 2026.
