A sequence of characters identifies an abstract or physical resource, such as a webpage, service, email address, phone number, book, real-world object (such as person or place), or concept. The resource need not be retrievable via the Internet or any computer network. Uniform Resource Locators (URLs) and Uniform Resource Names (URNs) are subordinate classifications and non-mutually exclusive.
Main Types of URIs
- Uniform Resource Locator (URL): This is the most common type of URI. URLs not only identify a resource but also provide a means of locating it by describing its primary access mechanism or network location. For example, the URL http://www.example.com identifies a resource (a website) and how to access it (using HTTP on the web).
- Uniform Resource Name (URN): A URN serves as a unique identifier for a resource, but unlike a URL, it doesn’t provide information on where the resource exists or how to access it. It’s used for resources whose location might change, as it remains consistent even if the resource moves. An example might be an ISBN for a book, which is a URN.
Applications in Digital Marketing
URIs are fundamental to the operation of the web, including its use in web browsers, web pages, and in many other internet protocols and applications. They enable the straightforward and reliable identification of resources across the web, which is crucial in digital marketing and sales strategies. URIs are used extensively in online advertising, search engine optimization, social media marketing, and in various other forms of digital communication to ensure consistency and accuracy in directing users to specific online locations.
