Machine Learning

Machine Learning (ML) is a subset of artificial intelligence that focuses on building systems that learn from data, identify patterns, and make decisions with minimal human intervention. In search, ML is used to improve ranking algorithms, understand user queries (through NLP), and detect spam. Algorithms like RankBrain and RankLib use machine learning to adjust the weight of ranking signals dynamically based on the query and user behavior. For SEOs, understanding the basics of machine learning is becoming increasingly important to interpret how search engines function and to leverage predictive analytics in search tools.
