What is redirect?
Redirect means forwarding. This refers to the redirection of a URL to another Internet address, which takes place automatically on the server side. If a website moves to another domain, redirection is a good option. Above all, it makes it possible to avoid duplicate content.
What does redirect mean for SEO?
Redirects are very important for search engine optimization. Websites can be redirected to other pages in a targeted manner. For example, it is possible to redirect "dead links" to a new target page using a 301 redirect. Duplicate content can also be counteracted.
If a page is relaunched, the existing link juice is not lost with a 301 redirect. In addition, no PageRank is lost when a redirect is set up.
A redirect setup is practical and useful in many respects. After all, no webmaster wants to lose PageRank and linkjuice due to a newly created page or other situations. It is also important to avoid duplicate content. If you have several pages, you can prevent duplicate content from being indexed and thus counteract a loss of ranking or complete removal from the index.
However, webmasters should avoid superfluous redirects. Under certain circumstances, they could negatively affect the performance of a website. At some point, Google can no longer follow several redirects, resulting in a crawling error.
