How much authority does a 301 pass to a different domain?
-
Hi,
A client of mine is selling his business to a brand new company. The brand new company will be using a brand new domain (no way to avoid that unfortunately) and the current domain (which has tons of authority, links, shares, tweets, etc.) will not be used. Added to that, the new company will be taking over all the current content with just a few minor changes. (I know, I wish we could use the old domain but we can't.)
Obviously, I am redirecting all pages on the current domain to the new domain via 301 redirects on a page by page basis. So, current.com/product-page-x.html redirects to new.com/product-page-x.html.
My client and the new company both are asking me how much link juice (and other factors) are passed along to the new domain from the old domain. All I can find is "not the full value" or variants thereof.My experience with 301 redirects in the past has been within a single domain and I've seen some of those pages have decent authority and decent rankings as a result of the 301 (no other optimization work was done or links were added).
Are there any studies out there that I'm missing that show how much authority/juice gets passed and/or lost via a 301 redirect? Anybody with a similar issue see any trends in page/domain authority and/or rankings?
Thanks for any insights and opinions you have.

We did a non E commerce site in late July/early August. Client had home page PA of 42 and DA of 38. This was to an entirely new domain. It took about 3 - 4 weeks and he is at same as before. (Not always the case, but this was 99.9%)
I would make sure that in the changeover, if someone new is handling new domain they have correctly handled the canonical redirect. Especially if there is any issue around web site and compensation, etc.

301 redirects pass over 90% of their value to the target page.

Can I use a 301 redirect to pass 'back link' juice to a different domain?
Hi, I have a backlink from a high DA/PA Government Website pointing to www.domainA.com which I own and can setup 301 redirects on if necessary. However my www.domainA.com is not used and has no active website (but has hosting available which can 301 redirect). www.domainA.com is also contextually irrelevant to the backlink. I want the Government Website link to go to www.domainB.com - which is both the relevant site and which also should be benefiting from from the seo juice from the backlink. So far I have had no luck to get the Government Website's administrators to change the URL on the link to point to www.domainB.com. Q1: If i use a 301 redirect on www.domainA.com to redirect to www.domainB.com will most of the backlink's SEO juice still be passed on to www.domainB.com? Q2: If the answer to the above is yes - would there be benefit to taking this a step further and redirect www.domainA.com to a deeper directory on www.domianB.com which is even more relevant?

ie. redirect www.domainA.com to www.domainB.com/categoryB - passing the link juice deeper.0 -
Redirect multiple domains to 1 domain or not?
Hi there, I have client who has multiple domains that already have some PA and DA. Problem is that most websites have the same content and rank better on different keywords.
Technical SEO | | Leaf-a-mark
I want to redirect all the websites to 1 domain because it’s easier to manage and it removes any duplicate content. Question is if I redirect domain x to domain y do the rankings of domain x increase on domain y? Or is it better to keep domain x separately to generate more referral traffic to domain y? Thanks in advance! Cheers0 -
301 Re-directing 'empty' domains
Hello, My client had purchased a few domains and 301 re-directed them, pointing to our main website. As far as I am aware the 'empty domains' are brand related but no content has ever been displayed on them, and I doubt they have much authority. The issue here is that we took a dive in ranking for our main keyword, I had a look on ahrefs and found the below: | www.empty-domain/our-keyword | 30 | 19 | 1 | fb 0

G+ 0
in 4 | REDIRECT 301 TO www.main-domain/our-keyword | 8 Feb '175 d | The ranking dip happened at the same time as the re-direct was re-discovered / re-crawled. Could the 'empty' URL in question been causing us any issues? I understand that this is terrible practice for 301 redirects, I was hoping someone in the community could shed light on any possible solution for this.0 -
Spammers created bad links to old hacked domain, now redirected to our new domain. Advice?
My client had an old site hacked (let's call it "myolddomain.com") and the hackers created many links in other hacked sites with links such as http://myolddomain.com/styless.asp?jordan-12-taxi-kids-cheap-T8927.html The old myolddomain.com site was redirected to a different new site since then, but we still see over a thousand spam links showing up in the new site's Search Console 404 crawl errors report. Also, using the links: operator in google search, we see many results of spam links. Should we be worried about these bad links pointing to our old site and redirecting to 404s on the new site? What is the best recommendation to clean them up? Ignore? 410s? Other? I'm seeing conflicting advice out there. The old site is hosted by the client's previous web developer who doesn't want to clean anything up on their end without an ongoing hosting contract. So beyond turning redirects on or off, the client doesn't want to pay for any additional hosting. So we don't have much control over anything related to "myolddomain.com". 😞 Thanks in advance for any assistance!

Redirect typo domains
Hi, What's the "correct" way of redirecting typo domains? DNS A record goes to the same ip address as the correct domain name Then 301 redirects for each typo domain in the .htaccess Subdomains on typo urls still redirect to www or should they redirect to the subdomain on the correct url in case the subdomain exists?

Domain authority and keyword difficulty
I know there are too many variables for a certain answer, however do people take their domain authority into account when using keyword difficulty tool? I have a new domain which only has a score of seven at the moment. When using the keyword searching tool what is the maximum difficulty level keywords people would target initially? Obviously I would seek to increase the difficulty of the words over time but to start off its a hard choice between keywords which can be ranked for in a reasonable period of time and the keywords which are getting enough traffic to make the effort worthwhile.

Multiple Domains, Same IP address, redirecting to preferred domain (301) -site is still indexed under wrong domains
Due to acquisitions over time and the merging of many microsites into one major site, we currently have 20+ TLD's pointing to the same IP address as our "preferred domain:" for our consolidated website http://goo.gl/gH33w. They are all set up as 301 redirects on apache - including both the www and non www versions. When we launched this consolidated website, (April 2010) we accidentally left the settings of our site open to accept any of our domains on the same IP. This was later fixed but unfortunately Google indexed our site under multiple of these URL's (ignoring the redirects) using the same content from our main website but swapping out the domain. We added some additional redirects on apache to redirect these individual pages pages indexed under the wrong domain to the same page under our main domain http://goo.gl/gH33w. This seemed to help resolve the issue and moved hundreds of pages off the index. However, in December of 2010 we made significant changes in our external dns for our ip addresses and now since December, we see pages indexed under these redirecting domains on the rise again. If you do a search query of : site:laboratoryid.com you will see a few hundred examples of pages indexed under the wrong domain. When you click on the link, it does redirect to the same page but under the preferred domain. So the redirect is working and has been confirmed as 301. But for some reason Google continues to crawl our site and index under this incorrect domains. Why is this? Is there a setting we are missing? These domain level and page level redirects should be decreasing the pages being indexed under the wrong domain but it appears it is doing the reverse. All of these old domains currently point to our production IP address where are preferred domain is also pointing. Could this be the issue? None of the pages indexed today are from the old version of these sites. They only seem to be the new content from the new site but not under the preferred domain. Any insight would be much appreciated because we have tried many things without success to get this resolved.
