Redirección

Redirección is a term commonly used in web development and internet navigation to describe the process of sending a user or a search engine from one web address (URL) to another. This is typically achieved through specific HTTP status codes. The most common type of redirection is a 301 redirect, which signifies a permanent move of a web page or resource. This tells browsers and search engines that the original URL is no longer valid and that they should update their records to point to the new location. Another type is a 302 redirect, which indicates a temporary move. In this case, the original URL is still considered the primary one, but the user is temporarily sent to a different address.

Redirections are essential for various reasons. They are used when a website undergoes a redesign, when domain names are changed, or when content is reorganized. They help maintain search engine rankings by transferring "link equity" or "link juice" from the old URL to the new one, preventing a drop in search engine results pages. Additionally, redirections ensure that users who have bookmarked old pages or clicked on outdated links are still able to access the intended content, providing a seamless browsing experience. Websites can implement redirections through server configurations or by using meta refresh tags, although the latter is generally less preferred for SEO purposes.
