A URL, or Uniform Resource Locator, is a reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it. URLs are essential for navigating the internet, allowing users to access websites, images, videos, and other online content. Each URL consists of several components, including the protocol (like HTTP or HTTPS), the domain name (like example.com), and the path to the specific resource. Understanding URLs is crucial for web development and digital marketing. They not only direct users to content but also play a significant role in search engine optimization (SEO). A well-structured URL can enhance user experience and improve a website's visibility in search results.
