Merging Domains... Sub-domains, Directories or Seperate Sites?
-
Hello!
I am hoping you can help me decide the best path to take here...
A little background:
I'm moving to a new company that has three old domains (the oldest is 10 years old), which get a lot of traffic from their e-letters. Until recently they have not cared about SEO. So the websites have some structural, coding, URL and other issues. The sites are indexed, but have a problem getting crawled and/or indexed for new content - haven't delved into this yet but am certain I will be able to fix any of these issues.
These three domains are PR4, PR4, PR5 and contain hundreds of unique articles.
Here's the question...
They want to move these three sites **to their main company site (PR4) and create sub domains for each one. **
I am wondering if this is a good idea or not. I have merged sites before (creating categories and/or directories) and the end result is that the ONE big site, is much for effective than TWO smaller, less authoritative sites. But the sub domain idea is something I am unsure about from an SEO perspective.
Should we do this with sub domains? Or do you think we should keep the sites separate? How do Panda and Penguin play into this?
Thanks in advance for the help!

P.S. I'm not a huge advocate in using PR as a measurement tool, but since I can't reveal the actual domains, I figured I would list it as a reference point.

Thanks for the reply.
I think at the end of the day, yes it does help the user to have it all in one place.
And thanks for reiterating what I already thought... directories are better than sub-domains.
To be honest, this article is what had me questioning sub-directories in the first place: http://www.seobook.com/subdomains-google-panda

I agree with what you are thinking. The biggest effect would be if you can move them all onto one domain name (sub-folders) and setup 301 redirects. Keep hosting those domains forever since the 301s would stay only as long as you own the domains and continue to host them to serve the 301.
Moving them to sub-domains might be minimal / zero effect. I only see risk in doing that.
Ask yourself: Does it help the users in integrating all the content into one big website ?
-
Thanks for the reply.
I guess my biggest concerns are getting the biggest SEO bump I can by consolidating this content, but avoid any content farm penalties.
I was thinking subdomains would be safer, but provide the little to no SEO value.
Thanks again, that's a nice little checklist for moving domains.
-
Thanks for the reply. Yes, that was my thinking as well.
I have been concerned that I would be in essence creating a content farm because like I mentioned, these sites have hundreds or thousands of articles on them. And they publish 1-3 articles a day on average.
So you did this in early 2011 and found no ill effects from Panda?
-
Subdomains are often viewed by google as different domains. That means, links that hit one of them benefit that subdomain but transfer fractional benefit to other subdomains and to the root.
If this was my project I would use folders instead of subdomains. Your designer can make them look unique if that is needed, however, with them all being in the root directory all of the incoming links will benefit the entire site.
In early 2011 I redirected two subdomains of a busy site (one more powerful than the root domain) into folders and the results have been kickass. Kickass.
-
As long as your content is well structured amongst the sub-domains and root domain I can't see why there would be any issues. When making the change ensure that you:
- Tell Google that the URL is moving (do this via Google Webmaster Tools)
- Add permanent 301 redirects from the old URLs and point to their respective URLs on the new domain (this is to ensure that any backlinks the old websites had will pass some link juice through)
- Don't stop hosting the old domains for say 6 months.
- Run a backlink check on the old URLs and try get those websites (provided they are of good quality) to update the link to the new sub-domain. For those that don't update the 301 redirect will help.
Have fun!

Redirection of 100 domain to Main domain affects SEO?
Hi guys, An email software vendor managed by a different area of my company redirected 100 domains used for unsolicited email campaigns to my main domain. These domains are very likely to get blacklisted at some point. My SEO tool now is showing me all those domains as "linking" to my main site as do-follow links. The vendor states that this will not affect my main domain/website in any way. I'm highly concerned. I would appreciate your professional opinion about this. Thanks!!

Using a Reverse Proxy and 301 redirect to appear Sub Domain as Sub Directory - what are the SEO Risks?
We’re in process to move WordPress blog URLs from subdomains to sub-directory. We aren’t moving blog physically, but using reverse proxy and 301 redirection to do this. Blog subdomain URL is https://blog.example.com/ and destination sub-directory URL is https://www.example.com/blog/ Our main website is e-commerce marketplace which is YMYL site. This is on Windows server. Due to technical reasons, we can’t physically move our WordPress blog to the main website. Following is our Technical Setup Setup a reverse proxy at https://www.example.com/blog/ pointing to https://blog.example.com/ Use a 301 redirection from https://blog.example.com/ to https://www.example.com/blog/ with an exception if a traffic is coming from main WWW domain then it won’t redirect. Thus, we can eliminate infinite loop. Change all absolute URLs to relative URLs on blog Change the sitemap URL from https://blog.example.com/sitemap.xml to https://www.example.com/blog/sitemap.xml and update all URLs mentioned within the sitemap. SEO Risk Evaluation We have individual GA Tracking ID and individual Google Search Console Properties for main website and blog. We will not merge them. Keep them separate as they are. Keeping this in mind, I am evaluating SEO Risks factors Right now when we receive traffic from main website to blog (or vice versa) then it is considered as referral traffic and new cookies are set for Google Analytics. What’s going to happen when its on the same domain? Which type of settings change should I do in Blog’s Google Search Console? (A). Do I need to request “Change of Address” in the Blog’s search console property? (B). Should I re-submit the sitemap? Do I need to re-submit the blog sitemap from the https://www.example.com/ Google Search Console Property? Main website is e-commerce marketplace which is YMYL website, and blog is all about content. So does that impact SEO? Will this dilute SEO link juice or impact on the main website ranking because following are the key SEO Metrices. (A). Main website’s Avg Session Duration is about 10 minutes and bounce rate is around 30% (B). Blog’s Avg Session Duration is 33 seconds and bounce rate is over 92%

Does having a different sub domain for your Landing Page and Blog affect your overall SEO benefits and Ranking?
We have a domain www.spintadigital.com that is hosted with dreamhost and we also have a seperate subdomain blog.spintadigital.com which is hosted in the Ghost platform and we are also using Unbounce landing pages with the sub domain get.spintadigital.com. I wanted to know whether having subdomain like this would affect the traffic metric and ineffect affect the SEO and Rankings of our site. I think it does not affect the increase in domain authority, but in places like similar web i get different traffic metrics for the different domains. As far as i can see in many of the metrics these are considered as seperate websites. We are currently concentrating more on our blogs and wanted to make sure that it does help in the overall domain. We do not have the bandwidth to promote three different websites, and hence need the community's help to understand what is the best option to take this forward.

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

Should I buy a .co domain if my preferred .com and .co.uk domain are taken by other companies?
I'm looking to boost my website ranking and drive more traffic to it using a keyword rich domain name. I want to have my nearest city followed by the keyword "seo" in the domain name but the .co.uk and .com have already been taken. Should I take the plunge and buy .co at a higher price? What options do I have? Also whilst we're on domains and URL's is it best to separate keywords in url's with a (_) or a (-)? Many thanks for any help with this matter. Alex
