Merging two different domains - subdomain or subfolder?
-
My company has two sites on different domains. We are considering merging the sites into one and keeping only the dominant domain. The dominate site is already a sub-domain of a larger organization so the new sub-domain would be two levels deep. I realize this is a little abstract so below is an example
Dominant company site: company.root-domain.com
Secondary company site: other-root-domain.com
When they merge, everything will be on company.root-domain.com. Should it be
Note: The other site has several hundred pages. Both sites have strong authority and link profiles. I want to maintain as much of the value on the other site as possible with the merge.

Thanks. I didn't think it would make too much of a difference but I wanted to get another opinion. I'm not worried about spammy URLs. Everything will be off of a short .edu - they look pretty clean with multiple subdomains.

I personally don't think it would make a difference one way or the other, as long as the proper 301 redirects are put into place and all traffic to the old URLs is sent to the correct new URL.
I do, however, think the sub-directory approach looks cleaner. Anything beyond the first sub-domain looks spammy to me (or just sloppy). That's just me though.

Why some domains and sub-domains have same DA, but some others don't?
Hi I noticed for some blog providers in my country, which provide a sub-domian address for their blogs. the sub-domain authority is exactly as the main domain. Whereas, for some other blog providers every subdomain has its different and lower authority. for example "ffff.blog.ir" and "blog.ir" both have domain authority of 60. It noteworthy to mention that the "ffff.blog.ir" does not even exist! This is while mihanblog.com and hfilm.mihanblog.com has diffrent page authority.

Subdomain cannibalization
Hi, I am doing the SEO for a webshop, which has a lot of linking and related websites on the same root domain. So the structure is for example: Root domain: example.com
Intermediate & Advanced SEO | | Mat_C
Shop: shop.example.com
Linking websites to shop: courses.example.com, software.example.com,... Do I have to check which keywords these linking websites are already ranking for and choose other keywords for my category and product pages on the webshop? The problem with this could be that the main keywords for the category pages on the webshop are mainly the same as for the other subdomains. The intention is that some people immediately come to the webshop instead of going first to the linking websites and then to the webshop. Thanks.0 -
Backlinks from old domain
Hi, We have gone through a change of company brand name including a new domain name.
Intermediate & Advanced SEO | | Agguk
We followed google recommendations at: https://support.google.com/webmasters/answer/83106?hl=en and it seems to have worked really well, the new domain has replaced the old in the google search results. My question: Still most of our backlinks, both anchor text and links use the old brand name and domain and it´s a slow process trying to update all references. Although they get redirected fine to the new domain (also following google recommendations), I wonder if the current scenario is doing any harm, SEO wise (other than the missed visual exposure of the new brand name) ? ...since the old brand name is not present at the new site I´m thinking of including "New brand name - previously old brand name" somewhere just to provide some sort of connection to all old backlinks, would that be unnecessary? I should mention that the old brand name actually includes our most important keyword but the new brand name does not. Thanks!0 -
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

Microsites: Subdomain vs own domains
I am working on a travel site about a specific region, which includes information about lots of different topics, such as weddings, surfing etc. I was wondering whether its a good idea to register domains for each topic since it would enable me to build backlinks. I would basically keep the design more or less the same and implement a nofollow navigation bar to each microsite. e.g.
Intermediate & Advanced SEO | | kinimod
weddingsbarcelona.com
surfingbarcelona.com or should I rather go with one domain and subfolders: barcelona.com/weddings
barcelona.com/surfing I guess the second option is how I would usually do it but I just wanted to see what are the pros/cons of both options. Many thanks!0 -
Turning off a subdomain
Hi! I'm currently working with http://www.muchbetteradventures.com/. They have a previous version of the site, http://v1.muchbetteradventures.com, as sub domain on their site. I've noticed a whole bunch of indexing issues which I think are caused by this. The v1 site has several thousand pages and ranks organically for a number of terms, but the pages are not relevant for the business at this time. The main site has just over 100 pages. More than 28,400 urls are currently indexed. We are considering turning off the v1 site and noindexing it. There are no real backlinks to it. The only worry is that by removing it, it will be seen as a massive drop in content. Rankings for the main site are currently quite poor, despite good content, a decent link profile and high domain authority. Any thoughts would be much appreciated!

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

Domain expiration and seo
My domain name is free with my service with yahoo but it expires every year and gets extended automatically as I continue service, how does this impact my seo efforts? I've heard that the search engines prefer sites to expire in 3 years or more? Is this a fact?
