Does redirect has an influence on SEO performance?
Redirects are a part of linking content within your website. 301 redirects carry 90-99% of link value to the redirected page. In case you move some content through several different pages, and all redirections are still active, you will probably sacrifice a small part of link value and page load speed. It is always a good idea to remove all unnecessary intermediaries.
But not every redirect is the same. 301 redirects, where the page is moved permanently, are most favorable for SEO. As we mentioned before, they pass 90-99% of link value. 302 redirects, which point to a temporarily redirected page, could lead to greater losses. Meta refresh redirects are done on the page level and not on the server. These redirects are most commonly associated with the text "If you are not redirected in five seconds, click here.". Meta refresh redirects pass some of the link value but are not recommended as part of the SEO strategy. They should be avoided as much as possible.
