Do you still loose 15% of value of inbound links when you redirect your site from http to https (so all inbound links to http are being redirected to https version)?

I know when you redesign your on website, you loose about 15% internally due to the 301 redirects (see moz article: https://moz.com/blog/accidental-seo-tests-how-301-redirects-are-likely-impacting-your-brand), but I'm wondering if that also applies to value of inbound links when you redirect your http://www.sitename.com to https://www.sitename.com.

I appreciate your help!

There is no value or authority lost with the redirects from non-secure to secure. Google gives slightly more weight to sites that go secure, so the trade off is they don't ding those types of redirects anymore.

Gary Illyes also recently stated that any type of 3xx redirect no longer loses PageRank - take that with a grain of salt though, I only provided this bit of info to put you at ease about redirects for HTTP > HTTPS.

Thanks, Logan. So do you think there is any value in having the top inbound links (highest domain authority) change their links to the https version of the site?

If it's easy for you to get them to change them, then yes I would, however I wouldn't spend more than a quick email on getting it done.

Exactly what Thomas said.
