After reading this material, you can find out what 301 redirect is when and why it is used. Well, for those who are already in the know, it will be useful to refresh their knowledge on this topic.

When used 301 redirect

  1. A classic example of using 301 redirect - two site names that differ only in the presence / absence of www and for a person seem to be exactly the same addresses. But for search engines, they are considered different. If you do not use 301 redirect in a similar situation, the impact on search output can be extremely negative due to duplication of content and weight redistribution.
