What are the pros and cons of moving one site onto a subdomain of another site?
-
Two sites. One has weaker sales. What would the benefits and problems for SEO of moving the weak site from its own domain to a subdomain of the stronger site?
-
Cons:
May lose some of the link juice from the 301 redirect from the old URL's (between 1 and 10% is the usual quoted figure)
Initial (usually short term) drop in rankings and potentially traffic of weaker site pages
www.weakersite.com is a "nicer" looking URL for offline marketing than www.strongersite.com/weakersite
Pro's:-
If on Subfolder rather than sub directory pages will benefit from domain authority and links to domain of stronger site.
Can focus future link building and on-page SEO efforts on one site rather than 2, potentially doubling the amount you can get done

If building from scratch and choice of 2 sites or 1 I would say go for one. As two already exist there is more of a call to be made.
-
Hey! That sure was a great seminar.
That advice makes sense. Thanks.
-
Aye.

Oh, and hey! I just noticed I know you from NOLA.

-
So it could get the full benefit of the stronger site's domain authority?
-
I would be more inclined to move it to a subdirectory on the stronger site.

Google Indexed a version of my site w/ MX record subdomain
We're doing a site audit and found "internal" links to a page in search console that appear to be from a subdomain of our site based on our MX record. Â We use Google Mail internally. Â The links ultimately redirect to our correct preferred subdomain "www", but I am concerned as to why this is happening and if it can have any negative SEO implications. Example of one of the links: Links aspmx3.googlemail.com.sullivansolarpower.com/about/solar-power-blog/daniel-sullivan/renewable-energy-and-electric-cars-are-not-political-footballs I did a site operator search, site:aspmx3.googlemail.com.sullivansolarpower.com on google and it returns several results.

Moving from a subdomain to subfolder
Hello, I am currently working on a site that is leveraging multiple subdomains. I wanted to see if it suggested to migrate them into subfolders. One of the subdomains is a .shop and the other is location specific. Thanks, T

One robots.txt file for multiple sites?
I have 2 sites hosted with Blue Host and was told to put the robots.txt in the root folder and just use the one robots.txt for both sites. Is this right? It seems wrong. I want to block certain things on one site. Thanks for the help, Rena

Removed Subdomain Sites Still in Google Index
Hey guys, I've got kind of a strange situation going on and I can't seem to find it addressed anywhere. I have a site that at one point had several development sites set up at subdomains. Those sites have since launched on their own domains, but the subdomain sites are still showing up in the Google index. However, if you look at the cached version of pages on these non-existent subdomains, it lists the NEW url, not the dev one in the little blurb that says "This is Google's cached version of www.correcturl.com." Clearly Google recognizes that the content resides at the new location, so how come the old pages are still in the index? Attempting to visit one of them gives a "Server Not Found" error, so they are definitely gone. This is happening to a couple of sites, one that was launched over a year ago so it doesn't appear to be a "wait and see" solution. Any suggestions would be a huge help. Thanks!!

"Fourth-level" subdomains. Any negative impact compared with regular "third-level" subdomains?
Hey moz New client has a site that uses: subdomains ("third-level" stuff like location.business.com) and; "fourth-level" subdomains (location.parent.business.com) Are these fourth-level addresses at risk of being treated differently than the other subdomains? Screaming Frog, for example, doesn't return these fourth-level addresses when doing a crawl for business.com except in the External tab. But maybe I'm just configuring the crawls incorrectly. These addresses rank, but I'm worried that we're losing some link juice along the way. Any thoughts would be appreciated!

301 redirects & merging two sites into one
We have a client that has two sites that rank well for different searches in their market. The main pages ranking are things like advice articles and news pieces. For various reasons, they just want one site. I believe they need to duplicate the content from the outgoing site and place it on the main site, with a 301 redirect from each old page to each new one. What happens when they eventually want to redirect the entire domain? Would these smaller, internal redirects become obsolete, therefore removing any link value they once had? I am not sure how this works or if there is a best practice way to do this. Thanks Gareth
