Gary Illyes is a Webmaster Trends Analyst at Google, and he
has spoken on several occasions about the use of "noindex" tags with
redirects.
A "noindex" tag is a signal that tells search
engines not to index a particular page. When combined with a redirect, this can
be used to prevent duplicate content issues.
In a tweet from 2018, Gary Illyes stated that using a
"noindex" tag with a redirect is not necessary, as the redirect alone
will prevent the original page from being indexed. He also mentioned that using
both a "noindex" tag and a redirect could potentially cause issues
with canonicalization.
However, in a more recent tweet from 2021, Gary Illyes
clarified that there are situations where using a "noindex" tag with
a redirect can be helpful. For example, if you have a page that has been
indexed by Google but is no longer needed, and you want to redirect it to
another page, using a "noindex" tag with the redirect can help speed
up the deindexing process.
In summary, while using a "noindex" tag with a
redirect is not always necessary, there may be situations where it can be
helpful. It's always a good idea to stay up-to-date with the latest advice from
Google and to use best practices when managing your website's content.
