Search Engine Journal: How Redirecting URLs Can Impact Your Website’s SEO

A new article on Search Engine Journal reports that an updated document from Google explains how redirecting URLs can impact a site’s appearance in search rankings.

Google just published an updated document that goes over six different types of URL redirects and their effects on search results. Google’s Gary Illyes and Lizzi Harvey worked together to add eight pages of content to an existing help page on 301 redirects. At only five paragraphs in length, the previous version of Google’s help guide was scant on details. Now the guide has information on each type of redirect, examples of what they look like, and details on how they impact Google Search. Here’s a summary of the newly added information:

Types of Redirects & Impact on Google Search
The difference between redirects is undetectable to visitors, but Google treats them differently in terms of the strength of signals sent to the target URL. Redirects fall into one of two categories — temporary or permanent. Google uses a permanent redirect as a strong signal that the target URL should be the one shown in search results. Conversely, Google uses a temporary redirect as a weak signal that the redirect target should be the URL shown in search results.

Additional Notes
There’s a lot to go through in Google’s new guide. Here are some final points about redirects based on the company’s recommendations. Choosing a redirect depends on how long you expect the redirect will be in place and what page you want Google Search to show in search results. If there’s any chance you’ll want a particular URL shown in search results again, then don’t permanently redirect it to another one. Always go for server side redirects whenever possible. Use JavaScript redirects only if you can’t do server side or meta refresh redirects. Don’t rely on crypto redirects for letting search engines know that your content has moved unless you have no other choice.
