The Permalink structure previously was year/month/day/post-name
I do not like this structure so changed it to domain.com/post-name

Now here is an interesting situation, thewordpresspro.net/09/10/17/post-name redirects to crunchpress.com/09/10/17/post-name and this page further to crunchpress.com/post-name

It become a double 301 redirect. When I analyzed it I become afraid of situation that this may cause problem in indexing.

After some research I cam across this page, at Google group a Google employ Berghausen has responded to a similar question. According to him Google indexes and support “double 301 redirects” however Google is slow on indexing these redirects.

So if you are in a similar situation i.e, changing your WordPress hosted sites domain and then Permalink structure, don’t worry, go ahead!
