Google updates its search algorithms almost every day to give users the best possible results.
These changes can worry marketers because organic search drives over 50% of all website traffic. A single update can affect the quantity and quality of traffic for any business.
Along with small daily changes, Google releases major updates called broad core updates. These are announced via Google Search Central, and they significantly impact how websites rank.
Next, this article explains Google’s 2025 algorithm updates, core changes, and AI features, and how marketers should respond to them.
