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.

Forwarding a .org domain to a .com domain: any negative impact to consider?
Hello! I have a question I've been unable to find a clear answer to. My client's primary domain is a .com with a satisfactorily high DA. My client owns the .org version of its domain (which has a very low DA, I suppose due to inactivity) but has never forwarded it on. For branding/visibility/traffic reasons, I'd like to recommend they set up the .org domain to forward to the .com domain, but I wanted to ask a few questions first: 1. Does forwarding low-value DA domains to high-value DA domains have any negative authority/SEO impact? 2. If the .org domain was to be forwarded, am I correct that an SSL cert is not necessary for it if the .com domain has an SSL cert? Thanks in advance!

Errors In Search Console
Hi All, I am hoping someone might be able to help with this. Last week one of my sites dropped from mid first day to bottom of page 1. We had not been link building as such and it only seems to of affected a single search term and the ranking page (which happens to be the home page). When I was going through everything I went to search console and in crawl errors there are 2 errors that showed up as detected 3 days before the drop. These are: wp-admin/admin-ajax.php showing as response code 400 and also xmlrpc.php showing as response code 405 robots.txt is as follows: user-agent: * disallow: /wp-admin/ allow: /wp-admin/admin-ajax.php Any help with what is wrong here and how to fix it would be greatly appreciated. Many Thanks

We switched the domain from www.blog.domain.com to domain.com/blog.
We switched the domain from www.blog.domain.com to domain.com/blog. This was done with the purpose of gaining backlinks to our main website as well along with to our blog. This set us very low in organic traffic and not to mention, lost the backlinks. For anything, they are being redirected to 301 code. Kindly suggest changes to bring back all the traffic.

Redirect typo domains
Hi, What's the "correct" way of redirecting typo domains? DNS A record goes to the same ip address as the correct domain name Then 301 redirects for each typo domain in the .htaccess Subdomains on typo urls still redirect to www or should they redirect to the subdomain on the correct url in case the subdomain exists?

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.

Any way around buying hosting for an old domain to 301 redirect to a new domain?
Howdy. I have just read this QA thread, so I think I have my answer. But I'm going to ask anyway! Basically DomainA.com is being retired, and DomainB.com is going to be launched. We're going to have to redirect numerous URLs from DomainA.com to DomainB.com. I think the way to go about this is to continue paying for hosting for DomainA.com, serving a .htaccess from that hosting account, and then hosting DomainB.com separately. Anybody know of a way to avoid paying for hosting a .htaccess file on DomainA.com? Thanks!

Exact match subdomains
Hi, I have seen significant SEO benefits from owning exact match domains and was wondering whether exact match subdomains hold the same (or some) of these benefits? eg. halloweencostumes.co.uk vs. halloween [dot] costumes.co.uk Many thanks.

Subdomain and Domain Rankings
I have read here that domain names with keywords might add a boost to your search rank For instance using a completely inane example monkey-fights.com might get a boost compared to mfl.com (monkey fighting league) when searching for "monkey fights" There seems to be a hot debate as to how much bonus the first domain might get over the second, but leaving that aside for the moment. Question 1. Would monkey-fights.mfl.com get the same kind of bonus as a root domain bonus? Question 2. If the answer to 1 above was yes would a 301 redirect from the suddomain URL to root domain URL retain that bonus I was just thinking on how hard it is to get root domains these days that are not either being squatted on etc. and if this might be a way to get the same bonus, or maybe subdomains are less bonus prone and so it would be a waste of time Thanks
