Google’s Gary Illyes has recently replied to a question on Twitter asking if it was advisable to change incoming links to the SSL version when switching to HTTPS. This is quite a relevant topic as many webmasters have recently changed over to HTTPS following the HTTPS algorithm that boosted encrypted websites in the search results.
While Gary Illyes admitted there was some benefit, he said that it was minimal and therefore “not worth it” provided your 301 redirects were implemented properly.

@pip_net if your redirects are properly implemented, the benefit from doing that is so minimal that IMO it's not worth it.

Whilst the response was in reference to sites moving to HTTPS, it also applies to any change of domain name or even change of a particular URL.
So What Percentage of PageRank or Link Juice is Lost When Using a 301 Redirect?
For those that take SEO very seriously any amount of loss of link power is potentially a concern, so what is the damage?
Matt Cutts was asked the exact question in relation to Page Rank back in February 2013; “Roughly what percentage of PageRank is lost through a 301 redirect”. You can see his reply in the video below:
