301 redirects

301 redirects are a type of HTTP status code used to permanently redirect one URL to another. When users or web crawlers visit the old URL, they are automatically sent to the new one. This ensures that both users and search engines access the correct page.

301 redirects are crucial for maintaining user experience and SEO. They prevent broken links or "404 Not Found" errors, which can frustrate users and disrupt navigation. They also help web crawlers understand that the old URL has been replaced, ensuring proper indexing.

For example, if you update your URL structure from example.com/old-product to example.com/new-product, a 301 redirect ensures users and crawlers are directed to the new URL seamlessly. This is especially important when reorganizing your website architecture, such as during a site redesign or migration.

From an SEO perspective, 301 redirects pass most of the link equity (or "SEO value") from the old URL to the new one. This helps preserve rankings and traffic when URLs change.

301 redirects also improve usability by allowing users to access the correct page, even when using outdated links or bookmarks. This smooth transition reduces bounce rates and keeps your website functioning efficiently.
