Google Rolls Out December 2025 Core Update, Causing Early Ranking Volatility
Google has officially begun rolling out its December 2025 Core Update, marking the third broad core algorithm update of the year. According to Google, the rollout may take several weeks to complete and is designed to improve how search systems assess relevance, content quality, and overall usefulness. Early signals from SEO tracking tools and webmaster discussions suggest noticeable ranking volatility across multiple industries, particularly for content-heavy and informational websites. As with previous core updates, Google reiterated that there are no specific penalties involved and no single fix for ranking drops. Instead, the update refines how multiple ranking systems work together. Site owners are encouraged to focus on long-term improvements such as content depth, originality, and clarity rather than reacting to short-term fluctuations. Reporting delays in Google Search Console may occur during the rollout, making it harder to immediately measure impact until the update fully settles.
