The key function of a search engine algorithm is to efficiently retrieve and rank search results based on their relevance to user queries. These algorithms analyze numerous factors, including keywords, site authority, and user engagement metrics, to determine how content should be indexed and displayed. This process is crucial for ensuring that users receive accurate and high-quality information quickly. Continuous updates to algorithms, like Google’s Panda and Penguin, aim to enhance user experience by improving search accuracy and filtering out low-quality content.
