Will errors on a subdomain effect the overall health of the root domain?
-
As stated in the question, we have 2 sub domains that contain over 2000 reported errors from SEOMOZ.
The root domain has a clean bill of health, and i was just wondering if these errors on the sub-domains could have a negative effect on the root domain in the eyes of Google.
Your comments will be appreciated.
Regards
Greg

Hi Greg - short answer is, it depends... Which means, of course, there's a long answer
In Google's eyes, subdomains are often, though not always, treated as separate entities from the main domain, meaning if content or issues on them is giving Google trouble, that won't necessarily extend to the other parts of the domain. However, this isn't always the case. We've certainly seen times when having spam or manipulative behavior on a subdomain meant the root domain and content on it suffered as well.
In the case you're describing, if the crawl issues are things like missing meta descriptions or long titles or other less-than-critical errors, I wouldn't be too worried. But if it's lots of 404s or duplicate content or infinite redirect loops, those could cause issues.
If you're really not worried at all about what Google thinks of the subdomains or the content on them, you could always use robots.txt to block them from accessing it, which should cause Google to not weight that content when judging the site as a whole.

Redirect multiple domains to 1 domain or not?
Hi there, I have client who has multiple domains that already have some PA and DA. Problem is that most websites have the same content and rank better on different keywords.
Technical SEO | | Leaf-a-mark
I want to redirect all the websites to 1 domain because it’s easier to manage and it removes any duplicate content. Question is if I redirect domain x to domain y do the rankings of domain x increase on domain y? Or is it better to keep domain x separately to generate more referral traffic to domain y? Thanks in advance! Cheers0 -

Expired domain 404 crawl error
I recently purchased a Expired domain from auction and after I started my new site on it, I am noticing 500+ "not found" errors in Google Webmaster Tools, which are generating from the previous owner's contents.Should I use a redirection plugin to redirect those non-exist posts to any new post(s) of my site? or I should use a 301 redirect? or I should leave them just as it is without taking further action? Please advise.

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

Umlaut in domain
Hi, My client wants to expand it's business to Germany and logically we need a domain name to match. We've found a great one and regsiterd several variants to it. However I just found out that in Germany it is possible (while here it's not) to register a domain with an umlaut. My question is: will google assign more value to: schädlinge.de than schadlinge.de when users search for schädlinge? If yes, how large will the difference be? (I will use an umlaut in the title etc) Kind regards,

Effective use of hReview
Hi fellow Mozzers! I am just in the process of adding various reviews to our site (a design agency), but I wanted to use the ratings in different ways depending on the page. So for the home page and the services (branding, POS, direct mail etc) I wanted to aggregate relevant reviews (giving us an average of all reviews for the home page, an average of ratings from all brand projects and so on). Then, I wanted to put specific reviews on our portfolio pages, so the review relates specifically to that project. This is the easiest to do as the hReview generator is geared up for reviews that come from one source, but I can't find a way of aggregating the star ratings to make an average rating rich snippet. Anyone know where I can get the coding for this? Thanks in advance! Nick.

How to 301 multiple domain names to a single domain
Hey, I tried to find and answer to this seemingly simple question, but no luck. So, I have one domain name with a website attached to it. I also registered all the other domain names that are similar to it or have different extensions - I want to redirect all the other domain names to my one main domain name without getting penalised by the big G. It looks like this: www.mainsite.com - this is my main domain I also have www.mainsite.com.au, www.mainsite.org, and www.mainsite.org.au which I all want to just redirect to www.mainsite.com I have been told that the best way to do this is a 301 redirect, but to do that you need to make a CNAME for all the other domains that points to www.mainsite.com. My problem is that I cannot seem to create a CNAME record for http://mainsite.com - I have it working for http://www.mainsite.com but not the non www record. What should I be doing differently? Is it just my DNS provider is useless? Thanks, Anthony
