Does redirection affect SEO?
Redirects are an integral part of linking content within your website. Thus, 301 redirects transfer 90-99% of the link value to the redirected page. If you move some content through several different pages and all redirects are still active, you will probably sacrifice a small part of the link value and load speed. It is always a good idea to remove all unnecessary intermediaries.
However, not all redirections are the same. 301 redirects, in which the page moves permanently, are the most favorable for SEO. As we mentioned earlier, they convey as much as 90-99% of the link value. 302 redirects, which indicate a temporarily redirected page, reportedly lead to higher losses. "Meta refresh" are redirects that take place at the page level, not the server itself. These redirections are most often associated with the text "If you are not redirected in five seconds, click here." Meta refresh conveys part of the link value but is not recommended as part of an SEO strategy. Avoid them whenever possible.
