301 redirects: What they are and how to use them correctly

A 301 redirect is an HTTP status code used to permanently redirect a web page from one URL to another, playing a critical role in maintaining SEO value and user experience when making changes to a website. These redirects ensure that traffic is smoothly transferred to the correct pages, preserving link equity and preventing "dead ends" that can frustrate users and negatively impact search engine rankings. They are particularly important when moving pages, consolidating content, migrating to a new domain, switching from HTTP to HTTPS, and resolving URL duplication issues such as those caused by trailing slashes or case discrepancies. By deploying 301 redirects, website owners can retain the SEO benefits of existing backlinks, ensure search engines index the correct content, and optimize search rankings by consolidating authority from multiple pages onto a single, stronger page.
