How to Handle SSL Certificates When Merging Domains?

Someone tweeted an interesting question about merging domains and SSL certificates. The question was whether it was necessary to keep paying for an SSL Security Certificate for the old domain.

Here is the question:

It’s not an easy to answer question. It’s technical because it deals with how browsers and search robots deal with secure links and redirects and the order in which those are processed.

MOz’s Dr. Pete suggested to keep paying for the old SSL in order to help Google understand the migration:

It was then suggested that when a browser opens an HTTPS link it first checks the validity of the SSL certificate and then sees the redirect, in that order.

John Mueller then stepped in and confirmed how browsers and Google handled this situation:

John Mueller tweeted:

“Browsers definitely need the certificate for HTTPS, even if you’re just redirecting.

Search engines can probably deal with it, but if there’s a chance the old URL is shown to users, just keep the certificate live too. You can get certificates for free nowadays.”

Mueller hedged his answer about how Google handled this site merge scenario by saying “probably.”

John Mueller subsequently added:

But he was unambiguous about how browsers handled it and suggested switching to a free SSL certificate for the old domain.
