URL normalization is the process of modifying and standardizing web URLs into a canonical form to ensure consistency and avoid duplication. This technique involves procedures such as converting the scheme and hostname to lowercase, removing default ports, resolving relative paths, eliminating redundant or unnecessary components like dot segments, and applying percent-encoding normalizations. The goal is to facilitate reliable URL comparisons, improve search engine indexing, and enhance web crawling efficiency.
