301 redirects matter just as much to users as they do to search engines. For example, when a website is redesigned and its URL structure changes, a 301 lets both users and search engines reach the new pages instead of hitting a 404, and it also passes the weight of the old pages on to the new ones. Below, 知了网络 SEO optimization shares the functions of 301 redirects and how to implement them.
1. Consolidating site weight
A 301 redirect is in effect a transfer of domain weight. For example, redirecting krseo.com to www.krseo.com means the weight of the former is transferred to the latter, consolidating the site's weight. 宁德SEO recommends doing this when the weight is above 1 for better results; it is a matter of sacrificing one site to complete another.
2. URL canonicalization
When both the bare domain and the www domain of our site can be opened, search engines may index the site in a confused way and weight may be split — for example, some pages are indexed under the bare domain and others under the www domain, and the same goes for rankings. This is bad for the consistency of the weight passed through our external links and is very unfriendly to search engines, so we should use 301 redirects to canonicalize URLs.
3. Changed inner page addresses
Sometimes a site changes the URLs of its existing inner pages for one reason or another. If nothing is done, visiting them returns a 404, so once a page address has changed you can solve this with a 301 redirect and avoid a large number of dead links.
That is the full content of "The Functions and Implementation of 301 Redirects," shared purely for webmasters to interact, exchange ideas and learn together. SEO optimization is an ongoing process, and I hope we can all make progress together.
