301 redirect
Check your list of 301 redirects and make sure they’re all relevant and set up correctly.
Even if all your 301 redirects are set up correctly, there may still be other questionable redirect elements on your website. Make sure you’re not losing visitors because of incorrect redirects. Also check for pages with 302 redirects, pages with meta refresh and pages with rel = “canonical”.
How 301 redirects affect SEO
301 redirects are permanent and are usually used to fix duplicate content or when URLs are no longer needed. Using 301 redirects is perfectly fine for SEO, as a 301 redirect sends all traffic from the old page to the new one. Make sure each 301 redirect points from the old URL to the most relevant new page.
