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 403 error
Hi Everyone, A crawler from our SEO tool detects a 403 error from a link from our main domain to a a couple of subdomains. However, these subdomains are perfect accessibly. What could be the problem? Is this error caused by the server, the crawlbot or something else? I would love to hear your thoughts.

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?

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. Â 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. Â What is the best way to solve this problem? Â 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

Move established site from .co.uk to .org - good or bad idea?
I am currently considering moving our site from the current .co.uk domain to the .org version which we also own. The site is established and indexed for 7 years, ranks well and has circa 10k traffic per month which is mainly UK & US traffic. The reason for the change to the .org domain is to make the site more global facing and give us the opportunity to develop the site into multi language within directories (.org/es/ etc.) and then target those to the local search engines. For the kind of site it is (community based) it wouldn’t really work to split this into lots of separate country targeted domains. So the choice is to either stick with the .co.uk and add the other foreign language specific content in directories within the .co.uk or move to the .org and do the same (there is also a potential third option of purchasing the .com which is currently unused but that could be pricey!) We are also planning a big overhaul of the site with redesign, lots of added content and reorganisation of the site – but are thinking that it would be better to move the domain on a 1:1 basis first with the current design, content and URL structure in place and then do the other changes 2 or 3 months down the line. I have read up on SEOmoz, google guidelines etc on moving a site to a new domain and understand the theoretical approach of moving the site and the steps to take (1to1 301 redirects, sitemaps on old and new etc) and I will retain ownership of the .co.uk so the redirects can remain in place indefinitely. However having worked so hard to get the site to where it is in the search engines and traffic levels I am very worried about whether the domain change is a good move. I am more than happy to accept a temporary fluctuation in rankings & traffic for 1 – 4 weeks as reported may happen as long as I can be sure it will return after a temporary period and be as strong (or almost as strong) as the previous rankings / traffic. Looking for peoples experiences to give me the confidence / reassurance to go ahead with this or any info on why I shouldn’t Thanks in advance for your advice. Adrian.

How to move my blog from subdomain to subfolder?
Not an unusual situation, I have a blog on blog.domain.com it has quite a few blog postings. The platform is old and will be scrapped, but the blog content itself is going to be moved to domain.com/blog. The current process is we are manually listing all linked to/content pages and we are going to 301 redirect them to their counterparts on the new blog. This is going to be a tedious process. A) Is there any way to automate the moving of the blog? B) What is the best way to do the massive 301 redirect, php headers, .htaccess? Should we move the individual pages with redirects, or redirect the domain in the .htaccess (this will be very difficult to match all the titles and file structure)?
