The HTTP 3xx status codes indicate that the requested resource has been temporarily or permanently moved to a different location, and the client should take action to retrieve it from the new location.
Some common examples of HTTP 3xx status codes include:
301 Moved Permanently: This is a permanent redirect that tells search engines that the original URL has been permanently moved to a new location. This type of redirect passes almost all of the original page’s link equity to the new URL.
302 Found: This is a temporary redirect that tells search engines that the original URL has been temporarily moved to a new location. This type of redirect is not recommended for SEO purposes as it does not pass the original page’s link equity to the new URL.
303 See Other: The requested resource can be found at a different URL, which should be retrieved using a GET request.
307 Temporary Redirect: 307 redirects are less commonly used than 302 redirects, but they can be useful in situations where a resource has been temporarily moved and the client should continue to use the same HTTP method for subsequent requests.
In general, HTTP 3xx status codes are used to enable websites to change the location of their content without breaking links and bookmarks.
