Google initiated the rollout of its December 2025 Core Update on December 4th. These updates are designed to adjust and refine the company's primary search ranking systems. The process is expected to take around 12 days to be fully implemented across all servers and regions. Early reports indicate this update is particularly focused on e-commerce and transactional queries. While Google has not detailed the specific changes, the SEO community is monitoring significant shifts in search rankings, particularly for online retailers. One analysis noted an average of a 23% traffic drop across some e-commerce sites, suggesting a significant potential impact for businesses reliant on Google search for revenue.
