301 Vs. 302 Redirection Best SEO Practice

Introduction

3xx is a http status code which is used for redirection from old url to new url.

Redirection Rule

If we are moving url permanently then use 301 redirection and moving url temporary, then use 302 redirection. Make sure old url content is equivalent to new url content otherwise send it to 404 error page.

 

Redirect All 404 to Home Page

Redirecting all broken pages (404) to home page is a bad idea because they their content is not equal to home page.

Redirecting All deleted pages to a specific 404 page is also not a good practice for a big website. You are wasting resources, yours and Google’s both.

Too Many Redirection

Don’t use multiple redirects. It may increase page load time. Although Google follow maximum 5 redirections.

if you use more than 5 redirections, Google will consider a soft 404 page.

301/302 Redirection Ranking Effect

According to Google, they will always pass the PageRank values through any kind of 3xx-redirect (301, 302, 303, 307, 308).
