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.

How to create a smooth blog migration from subdomain to subfolder main?
Hi mozzers, We have decided to migrate the blog subdomain to the domain's subfolder (blog.example.com to example.com/blog). To do this the most effective way and avoid impact SEO negatively I believe I have to follow this checklist: Create a list of all 301 redirects from blog.example.com/post-1 to example.com/post-1 Make sure title tags remain the same on main domain Make sure internal links remain the same Is there something else I am missing? Any other best practices? I also would like to have all blog post as AMPs. Any recommendations if this something we should do since we are not a media site? Any other tips on successfully implementing those types of pages? Thanks

Combining Two Sites With Similar Domain Authority
Hello, We run two sites with the same product, product descriptions and url structure. Essentially, the two sites are the same except for domain name and minor differences on the home pages. We've run this way for quite a few years. Both sites have a domain authority of 48 and there are not a large number of duplicate incoming links. I understand the "book" to say we should combine the sites with 301's to the similar pages. I am concerned about doing this because "site 2" still does about 20% of our business. We have been losing organic traffic for a number of years. I think this mainly has to do with a more competitive environment. However, where google used to serve both our sites for a search term it now will only show one. How much organic benefit should we see if we combine. Will it be significant enough to merge the two sites. Understandably, I realize the future can't be predicted but I would like to know if anyone has had a similar experience or opinion Thanks

301 Redirecting from domain to subdomain
We're taking on a redesign of our corporate site on our main domain. We also have a number of well established, product based subdomains. There are a number of content pages that currently live on the corporate site that rank well, and bring in a great deal of traffic, though we are considering placing 301 redirects in place to point that traffic to the appropriate pages on the subdomains. If redirected correctly, can we expect the SEO value of the content pages currently living on the corporate site to transfer to the subdomains, or will we be negatively impacting our SEO by transferring this content from one domain to multiple subdomains?

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

Blog subdomain not redirecting
Over the last few weeks I have been focused on fixing high and medium priority issues, as reported by the Moz crawler, after a recent transition to WordPress. I've made great progress, getting the high priority issues down from several hundred (various reasons, but many duplicates for things like non-www and www versions) to just five last week. And then there's this weeks report. For reasons I can't fathom, I am suddenly getting hundreds of duplicate content pages of the form http://blog.<domain>.com</domain> (being duplicates with the http://www.<domain>.com</domain> versions). I'm really unclear on why these suddenly appeared. I host my own WordPress site ie WordPress.org stuff. In Options / General everything refers to http://www.<domain>.com</domain> and has done for a number of weeks. I have no idea why the blog versions of the pages have suddenly appeared. FWIW, the non-www version of my pages still redirect to the www version, as I would expect. I'm obviously pretty concerned by this so any pointers greatly appreciated. Thanks. Mark

Two Different Domains exact same content
Hello, I suspect I know the answer to this but would like to have it confirmed. I have been speaking to a company the last couple of weeks who have 2 domains with the exact same content. Possible a third but they haven't supplied a link. This from all I've read would be a huge problem for ranking and SEO. What would be the best way to deal with this ? I did do a search and found articles/questions on same content on the same site and in articles etc but nothing about exactly the same websites on 2 domains. Cheers David.

Do low quality subdomains affect the ranking performance/quality of a root domain?
Hi, Late last year the company I work for launched two new websites that, at the time, we believed were completely separate from our main website. The two new websites were set up externally and were not well-planned from an SEO perspective (LOTS of duplicate content) - hence, they have struggled to rank on Google. Since the launch of the new websites we have also noticed that our main website (that previously ranked very well) has suffered a decline in visitation and search engine rank. We initially attributed this to a number of factors, including the state of the market, and ramped up our SEO efforts (seeing minor improvement). We have since realised that these two new websites have been set up as subdomains of our main website, with MOZ displaying the same domain authority and root domain backlink profile. My question is, do poor quality subdomains affect the ranking performance of a root domain? I have not yet managed to find a definitive answer. Please let me know if more information is required - I am quite new to the whole SEO concept. Thanks! Amy

Is it safe to redirect our .nl (netherlands) domain that we have just purchased to our .com domain?
Hi all! We've recently developed a German version of our website with German translation and now we have just purchased a .nl domain, but with this one, we want all of the copy to remain in English. Is it ok to redirect our .nl domain to our current .com website or will this give us bad SEO points? Thank you!
