Web algorithms are sets of rules or procedures used to process data on the internet. They help in organizing, searching, and retrieving information efficiently. Common examples include algorithms used by search engines like Google to rank web pages based on relevance and quality. These algorithms analyze various factors, such as keywords, user behavior, and site structure, to deliver the most useful results. Additionally, recommendation algorithms on platforms like Netflix or Amazon suggest content or products based on user preferences and past interactions, enhancing the overall online experience.
