The website misses the reason that I have not moved my domains to HTTPS: Google.

Google treat the HTTP and HTTPS pages as separate for link ranking purposes, so there is a chance that a move will destroy 10 years of link ranking. Even with redirects, there is a non-zero chance of the business being destroyed.

If Google would treat HTTP and HTTP pages as the "same page" then I would move tomorrow.

Google doesn't penalize redirects from HTTP to HTTPS: https://moz.com/blog/301-redirection-rules-for-seo

I would suggest an experiment, to move one single (well ranked) page to HTTPS, and see the traffic impact over some reporting period that makes sense. In terms of Google search, nowadays I'm not sure link longevity really matters; otherwise I don't think I would get spammy pages consistently as results.

I'm not that knowledgeable on SEO, but thought that this can be controlled with the `link rel=canonical` and redirecting.
