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.

Subdomain or subfolder?
Hello, We are working on a new site. The idea of the site is to have an ecommerce shop, but the homepage will be a content page, basically a blog page.
Technical SEO | | pinder325
My developer wants to have the blog (home) page on a subdomain, so blog.example.com, because it will be easier to make a nice content page this way, and the the rest of the site will just be on the root domain (example.com). I'm just worried that this will be bad for our SEO efforts. I've always thought it was better to use a sub folder rather than a subdomain. If we get links to the content on the subdomain, will the link juice flow to the shop, on the root domain? What are your thoughts?0 -
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. We use Google Mail internally. 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.

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

Robots.txt on subdomains
Hi guys! I keep reading conflicting information on this and it's left me a little unsure. Am I right in thinking that a website with a subdomain of shop.sitetitle.com will share the same robots.txt file as the root domain?

No index on subdomains
Hi, We have a subdomain that is appearing in the search results - I want to hide this as it looks really bad. If I were to add the no index tag to the sub domain would URL would this affect the whole domain or just that sub domain? The main domain is vitally important - it is just that sub domain I need to hide. Many thanks

Staging site and "live" site have both been indexed by Google
While creating a site we forgot to password protect the staging site while it was being built. Now that the site has been moved to the new domain, it has come to my attention that both the staging site (site.staging.com) and the "live" site (site.com) are both being indexed. What is the best way to solve this problem? I was thinking about adding a 301 redirect from the staging site to the live site via HTACCESS. Any recommendations?

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

Google.ca is showing our US site instead of our Canada Site
When our Canadian users who search on google.ca for our brand (e.g. Travelocity, Travelocity hotels, etc.), the first few results our from our US site (travelocity.com) rather than our Canadian site (travelocity.ca). In Google Webmaster Tools, we've adjusted the geotargeting settings to focus on the appropriate locale, but the wrong country TLD is still coming up at the top via google.ca. What's the best way to ensure our Canadian site comes up instead of the US site on google.ca? Thanks, Tory Smith
