Can subdomains hurt your primary domain's SEO?
-
Our primary website https://domain.com has a subdomain https://subDomain.domain.com and on that subdomain we have a jive-hosted community, with a few links to and fro. In GA they are set up as different properties but there are many SEO issues in the jive-hosted site, in which many different people can create content, delete content, comment, etc. There are issues related to how jive structures content, broken links, etc. My question is this: Aside from the SEO issues with the subdomain, can the performance of that subdomain negatively impact the SEO performance and rank of the primary domain? I've heard and read conflicting reports about this and it would be nice to hear from the MOZ community about options to resolve such issues if they exist. Thanks.

All of the content that you have on a subdomain and all of the links that the subdomain attracts could have been working to strengthen your root domain.
In Google you are going out to fight the heavyweights. Do you want to do that with a couple light weight platforms or do you want to unite the clans and attack with all that you got. That is the choice that you make by running subdomains.
I moved and redirected my subdomains into folders on the main website a long time ago and the results were great.

Under certain circumstances it can harm the rankings and SEO performance of your main site. In terms of low-end technical SEO issues like broken links and stuff, that usually wouldn't be a problem (unless it were creating loads of broken links from the sub-site, to the main site). If you had a more substantial issue like an active penalty (manual GSC notification) or a malware threat (or hacked content) on your subdomain, that could assuredly harm the main site's rankings. Except in extreme circumstances such as these - I wouldn't worry about it too much

Should I redirect a domain we control but which has been labeled 'toxic' or just shut it down?
Hi Mozzers: We recently launched a site for a client which involved bringing in and redirecting content which formerly had been hosted on different domains. One of these domains still existed and we have yet to bring over the content from it. It has also been flagged as a suspicious/toxic backlink source to our new domain. Would I be wise to redirect this old domain or should I just shut it down? None of the pages seem to have particular equity as link sources. Part of me is asking myself 'Why would we redirect a domain deemed toxic, why not just shut it down.' Thanks in advance, dave

Should I run my Shopify store on a subdomain or buy a new domain for it?
I'm planning to set up a subdomain for my Shopify store but I'm not sure if this is the right approach. Should I purchase a separate domain for it? I'm running Wordpress on my website and want to keep it that way. I want to use Shopify for the ecommerce side. I want to link the store from the top nav and of course I'll use CTA's in a variety of ways to point to merchandise and other things on the store side. Thanks for any help you can offer.

Can't generate a sitemap with all my pages
I am trying to generate a site map for my site nationalcurrencyvalues.com but all the tools I have tried don't get all my 70000 html pages... I have found that the one at check-domains.com crawls all my pages but when it writes the xml file most of them are gone... seemingly randomly. I have used this same site before and it worked without a problem. Can anyone help me understand why this is or point me to a utility that will map all of the pages? Kindly, Greg

How can I get a list of every url of a site in Google's index?
I work on a site that has almost 20,000 urls in its site map. Google WMT claims 28,000 indexed and a search on Google shows 33,000. I'd like to find what the difference is. Is there a way to get an excel sheet with every url Google has indexed for a site? Thanks... Mike

Subdomains and SEO - Should we redirect to subfolder?
A new client has mainsite.com and a large numer of city specific sub domains i.e. albany.mainsite.com. I think that these subdomains would actually work better as subfolders i.e mainsite.com/albany rather than albany.mainsite.com. The majority of links on the subdomains link to the main site anyway i.e. mainsite.com/contactus rather than albany.mainsite.com/contactus. Having mostly main domain links on a subdomain doesnt seem like clever link architecture to me and maybe even spammy. Im not overly familiar with redirecting subdomains to subfolders. If we go the route of 301'ing subdomains to subfolders any advice/warnings?

Move blog from subdomain to main domain on ecom site?
I am wondering what my fellow mozers think. Pretty set about my direction but want to get any other input to aid in my decision. Have an ecom site with a www.blog.maindomain.com. The blog is fairly new and no major rankings. There are only about 30 posts. This isn't a super competitive market and the blogging won't be a huge part of our content strategy but I would like to use it for passing juice etc. Would you go through the trouble to move the blog to www.site.com/blog and redirecting all the old content to new?

Is 404'ing a page enough to remove it from Google's index?
We set some pages to 404 status about 7 months ago, but they are still showing in Google's index (as 404's). Is there anything else I need to do to remove these?
