Will Switching to HTTPS Lower My Domain Authority?
-
Hi All,
I had a quick look online but couldn't find any information regarding this so thought I would ask. Please point me in the right direction if it has been asked before of if there are any useful articles online.
We are currently in the process of switching one of our clients old sites from http to https, we have done all of the steps except from making the https version the main domain, or 301ing the http version to the https version.
If we were to do this would we expect to see a drop in domain authority? a drop in keyword rankings? or is there anything else we should be worried about?
Thanks Mozzers

There's a couple of questions to answer here. The first is the difference between asking "Will our Domain Authority Decrease?" versus "Will our Traffic & Rankings Decrease?". The second question is more important so I'll cover that first.
The official answer from Google is that, no, your traffic and rankings will not decrease. In practice, however, a number of people have seen 5-15% traffic drops for weeks or months after the transfer - even when completed correctly. The general assumption is that this is due to creating redirects for http -> https, which traditionally reduces the value of your inbound link profile.
With that said, it's small enough that you can recover quickly with some link reclamation - basically you should update the links you have control over and also email friendly webmasters and say "we changed our site to be HTTPS secure and were wondering if you could update your link on domain.com/xyzpage/".
Deacyde's notes on updating internal links are also correct. You should also reference popular "ssl migration" guides like this one from Yoast: https://yoast.com/dev-blog/move-website-https-ssl/
In regards to your exact question - "Will our Domain Authority Decrease?" - this could reference the literal Domain Authority that is measured by Moz, or you could be referencing the broader concept of domain authority in terms of how Google views your website. I don't have an exact answer for how Moz handles normal 301 redirects and if they treat https redirects different. I would assume that Domain Authority might drop slightly, but that's a guess and not an official answer. As noted above Google says that your website will be treated the same, and I think that is the case within a few months, but there can be initial traffic drops, and worse if you handle the migration incorrectly.

I'm going through this right now, am a month and two weeks into it so far.
I went through the whole site to confirm no http urls were hardcoded that all urls used either relative or //site.com, images and resources too if you host your own.
After that I made a new google webmaster site for the https version I was about to redirect to. So I could monitor the amount of pages indexed compared to the http site,
As long as you have the redirect in order, there shouldn't be a reason to lose Domain Authority, since moving to a https sitewide is promoted in google seo, via the indexing more of https sites as long as you followed their guidelines: https://googlewebmastercentral.blogspot.com/2015/12/indexing-https-pages-by-default.html
As far as I've read and understood, you're more likely to lose DA from losing a high DA backlink, being penalized, loosing a good chunk of indexed pages from google, and so on. Converting to an https sitewide is improving your site and the user experience via adding that extra layer of security, which I haven't heard of penalizing a site for that yet.
Keyword rankings I feel have better chance of improving over time, long term that is, since users will tend to want to click on https sites when choice is with an unsecured site, especially when using credit cards, so that would improve your ranking signals overall.
Just make sure your https site is gaining indexed pages and the http site will drop in total and you're doing great! Keep up any 404 fixes prompt to keep index rate constant.
Hope this helps!

Cross domain canonical issue
Hello fella SEOs! I have a very intriguing question concerning different TLDs across the same domain. For eg: www.mainwebsite.com, www.mainwebsite.eu, www.mainwebsite.au, www.mainwebsite.co.uk etc... Now, assuming that all these websites are similar in terms of content, will our lovely friend Google consider all these TLDs as only one and unique domain or will this cause a duplicate content problem? If yes, then how should I fix it? Thnx for your precious help guys!

Domain Switch - With lost control of original domain.
Hey all, A client finally sold a domain name after being harassed to sell for many years, without talking to us about it first. They moved the site to a new domain, and the purchasing company took over the original domain. Then they called me, wondering why the site is no longer showing up in Google. I've done some initial research, and everything I find for advice assumes that you have control over the original domain. We don't. I'm hoping someone here has some creative advice, so we don't have to start from the beginning, and/or painfully update links we've acquired. My only thought was that the new company may be kind enough to post 301's for us if we provided them.... Any thoughts / advice / life rings will be greatly appreciated! 🙂

Should a 301 from a penalised domain to a new domain be removed?
A business traded on a domain let's say example.COM which was heavily penalised due to non-removable spammy back links. Their previous SEO advised them to set up on example.CO.UK but redirected example.COM to example.CO.UK. Example.CO.UK ranks very poorly, presumably due to being 'tarred with the same brush' i.e. attributed with the ills of example.COM. Will it do any good to remove the redirect or is example.CO.UK now doomed as well?

Best strategy for redirecting domain authority from an acquired site...?
Hi all, I'm an in-house for a company that made several acquisitions last year prior to my starting. I'm just now hearing about several loose-ends websites that belong to companies that have been absorbed by us. The question is how to best approach the task of utilizing that site's domain authority to our site's benefit. There is already a link to the homepage in the header of the site in question (our logo's right under theirs) so we're already getting some linkjuice. Looks like the whois information never changed. Here are the options I'm considering: 1. Blanket redirect (all of their pages there into our home page) - not ideal. 2. Targeted redirect (try to "connect the dots" between content pages with similar subjects/keyword relevance - better than #1, but is it worth the extra effort? 3. More linking (add more strategically placed and keyword optimized links back to our site) - also more work, but certainly do-able if the consensus is to leave the site up. 4. Any other suggestions? Thanks for your help everyone!

Domain redirection and seo implications
We have an existing site that is a subdomain but we recently acquired an exact match domain. Will building links to the exact match domain and having the domain point at our existing subdomain work or should we convert the entire site and redirect our existing subdomain to the new domain? What I'm trying to figure out is how to maximize the benefit here and how the existing mass of links pointing to our existing subdomain (shop.domain.com) can be used. New domain: keywordshop.com Existing URL: shop.domain.com
