Recovery from a HTTP to HTTPs migration using 302s ?

[yaelslater]

If a website did an HTTP to HTTPS migration using 302 re-directs, that were corrected to 301s about 4 months later, what is the expected impact? Will the website see a full recovery or has the damage been done? Thanks to anyone who can shed some light on this...

Hey,

If you check today's whiteboard Friday with Dr. Pete (https://moz.com/blog/arent-301s-302s-canonicals-all-basically-the-same-whiteboard-friday), he mentions this case:

"Some types of 302s just don't make sense at all. So if you're migrating from non-secure to secure, from HTTP to HTTPS and you set up a 302, that's a signal that doesn't quite make sense. Why would you temporarily migrate?"

So answering your question, Google probably considered your initial http -> https redirects as 301.
