Legacy domains
-
Hi all,
A couple of years ago we amalgamated five separate domains into one, and set up 301 redirects from all the pages on the old domains to their equivalent pages on the new site. We were a bit tardy in using the "change of address" tool in Search Console, but that was done nearly 8 months ago now as well.
Two years after implementing all the redirects, the old domains still have significant authority (DAs of between 20-35) and some strong inbound links. I expected to see the DA of the legacy domains taper off during this period and (hopefully!) the DA of the new domain increase. The latter has happened, although not as much as I'd hoped, but the DA of the legacy domains is more or less as good as it ever was?
Google is still indexing a handful of links from the legacy sites, strangely even when it is picking up the redirects correctly. So, for example, if you do a site:legacydomain1.com query, it will give a list of results which includes pages where it shows the title and snippet of the page on newdomain.com, but the link is to the page on legacydomain1.com.
What has prompted me to finally try and resolve this is that the server which hosted the original 5 domains is now due to be decommissioned which obviously means the 301 redirects for the original pages will no longer be served. I can set up web forwarding for each of the legacy domains at the hosting level, but to maintain the page-by-page redirects I'd have to actually host the websites somewhere. I'd like to know the best way forward both in terms of the redirect issue, and also in terms of the indexing of the legacy domains?
Many thanks,
Dan

Thanks both for responding - EGOL's response was a really straight answer, although I appreciate the detail from Ruth.

All of my 301 redirects will still be in place when I attend my own funeral and my business succession plan orders the new owners to maintain them.
If you don't redirect and there are still links out there on other websites, Google spiders will not follow them to your site. Human visitors who find these links and click them will discover air instead of your website.

Hi Dan,
It's important to remember that Domain Authority is a Moz-specific metric, measuring the power that inbound links to a domain are passing to it. It's based on a lot of research and information about how Google measures links, but isn't necessarily a reflection of how Google is actually perceiving and rating the inbound links to your site (since no outside party knows for sure exactly how Google is measuring link signals at any given time). Since those links still point to the legacy domains, they are still coming up in the Moz tools as having high DA. It's probable that Google is interpreting those signals passing through your redirects correctly and passing that link value on to your main domain, but if those redirects go away, that may change.
URLs will often remain in the index when they have links pointing to them, because Google is indexing the presence of that link - but a URL showing up in a site: search doesn't necessarily mean that it's ever showing up for any query. Is your main domain still getting a lot/much/any traffic from your legacy domains through those redirects? How much traffic is still getting to those legacy domains (whether via organic search traffic to still-indexed pages or, more likely, from people clicking on inbound links to the old pages) will dictate whether or not you need to keep the redirects live.
One thing I would recommend doing, that I always recommend when a domain is moved, is reaching out to the sites that link to your old domain and seeing if you can get them to update the links to the new domain. You won't have anywhere close to a 100% success rate with this, but it can decrease the number of links that are passing value through redirects and increase the number that pass value directly.
If you do decide to decommission the server and not re-host the redirects elsewhere, I would recommend planning that move in conjunction with a link building and promotion campaign for the new site, to attract new links to make up for any link juice that is lost from the old domains' redirects. I hope that helps!

How Can I Redirect an Old Domain to Our New Domain in .htaccess?
There is an old version of http://chesapeakeregional.com still floating around the web here: http://www.dev3.com.php53-24.dfw1-2.websitetestlink.com/component/content/category/20-our-services. Various iterations of this domain pop up when I do certain site:searches and for some queries as well (such as "Diagnostic Center of Chesapeake"). About 3 months ago the websitetestlink site had files and a fully functional navigation but now it mostly returns 404 or 500 errors. I'd like to redirect the site to our newer site, but don't believe I can do that in chesapeakeregional.com's .htaccess file. Is that so and would I need access to the websitetestlink .htaccess to forward the domain? Note* I (nor anyone else in our organization) has the login for the old site. The new site went live about 9 months before I arrived at the organization and I've been slowly putting the pieces together since arriving.

Subdomain replaced domain in Google SERP
Good morning, This is my first post. I found many Q&As here that mostly answer my question, but just to be sure we do this right I'm hoping the community can take a peak at my thinking below: Problem: We are relevant rank #1 for "custom poker chips" for example. We have this development website on a subdomain (http://dev.chiplab.com). On Saturday our live 'chiplab.com' main domain was replaced by 'dev.chiplab.com' in the SERP. Expected Cause: We did not add NOFOLLOW to the header tag. We also did not DISALLOW the subdomain in the robots.txt. We could have also put the 'dev.chiplab.com' subdomain behind a password wall. Solution: Add NOFOLLOW header, update robots.txt on subdomain and disallow crawl/index. Question: If we remove the subdomain from Google using WMT, will this drop us completely from the SERP? In other words, we would ideally like our root chiplab.com domain to replace the subdomain to get us back to where we were before Saturday. If the removal tool in WMT just removes the link completely, then is the only solution to wait until the site is recrawled and reindexed and hope the root chiplab.com domain ranks in place of the subdomain again? Thank you for your time, Chase

Domain dominance
I've just started to work for a company who've purchased masses of domains with every conceivable permutation based on all their products with every extension possible e.g .biz . eu. .net (including .co.uk and .com of course). I have two questions: 1. Is it worth keeping all these (they want to add more) domains or let them expire? 2. All the purchased domains are online - is there any point (they redirect with a 301)?

What are the effects of having Multiple Redirects for pages under the same domain
Dear Mozers, First of all let me wish you all a Very Happy, Prosperous, Healthy, Joyous & Successful New Year ! I'm trying to analyze one of the website's Web Hosting UK Com Ltd. and during this process I've had this question running through my mind. This project has been live since the year 2003 and since then there have be changes made to the website (obviously). There have also been new pages been added, the same way some new pages have even been over-written with changes in the url structures too. Now, coming back to the question, if I've have a particular url structure in the past when the site was debuted and until date the structure has been changes thrice (for example) with a 301 redirect to every back dated structure, WOULD it impact the sites performance SEOwise ? And let's say that there's hundreds of such redirections under the same domain, don't you think that after a period of time we should remove the past pages/urls from the server ? That'd certainly increase the 404 (page not found) errors, but that can be taken care of. How sensible would it be to keep redirecting the bots from one url to the other when they only visit a site for a short stipulated time? To make it simple let me explain it with a real life scenario. Say if I was staying a place A then switched to a different location in another county say B and then to C and so on, and finally got settled at a place G. When I move from one place to another, I place a note of the next destination I'm moving to so that any courier/mail etc. can be delivered to my current whereabouts. In such a case there's a less chance that the courier would travel all the destinations to deliver the package. Similarly, when a bot visits a domain and it finds multiple redirects, don't you think that it'd loose the efficiency in crawling the site? Ofcourse, imo. the redirects are important, BUT it should be there (in htaccess) for only a period of say 3-6 months. Once the search engine bots know about the latest pages, the past pages/redirects should be removed. What are your opinions about this ?

XML Sitemap on another domain
Hi, We've rebuilt our website and created a better sitemap index structure. There's a good chance that we not be able to append the XML files to existing site for technical reasons (don't get me started). I'm reaching out because I'm wondering if can we place the XML files on another website or subdomain? I know this is not best practice and probably very grey but I'm looking for alternatives. If there answer is DON'T DO IT let me know too. Thx

Redirect old .net domain to new .com domain
I have a quick question that I think I know the answer to but I wanted to get some feedback to make sure or see if there's additional feedback. The long and short of it is that I'm working with a site that currently has a .net domain that they've been running for 6 years. They've recently bought a .com of the same name as well. So the question is: I think it's obviously preferable to keep the .net and just direct the .com to it. However, if they would prefer to have the .com domain, is 301'ing the .net to the .com going to lose a lot of the equity they've built up in the site over the past years? And are there any steps that would make such a move easier? Also, if you have any tips or insight just into a general transition of this nature it would be much appreciated. Thanks!

SEO value in multiple backlinks from same domain and from various sub-domains.
A site has a link to my site as one of their main tabs, which means whenever a user clicks through to another page within the site, my link - being a main tab - is there. This creates thousands of links from this site. How does Google treat this? Do we have a rough formula estimate. In other words, assume it creates 1,000 backlinks would the SEO value be around the same as if I had just 2 link total as a main tab, but on 2 different non-related sites? Or, does it actually count fully as 1,000 links? Links from various sub-domains. Several .EDU's are linking to my site. Different schools within the overall same university. Example: nursing.abc.edu links to my site, but so does business.abc.edu. For SEO does that count as much as if I had links from complete non-related universities, or would Google evaluate that these links are related (since same main domain) and that will discount any links more than 1 to some extent? If discounted, then what do we estimate the discount to be? thank yoyu
