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

After hack and remediation, thousands of URL's still appearing as 'Valid' in google search console. How to remedy?
I'm working on a site that was hacked in March 2019 and in the process, nearly 900,000 spam links were generated and indexed. After remediation of the hack in April 2019, the spammy URLs began dropping out of the index until last week, when Search Console showed around 8,000 as "Indexed, not submitted in sitemap" but listed as "Valid" in the coverage report and many of them are still hack-related URLs that are listed as being indexed in March 2019, despite the fact that clicking on them leads to a 404. As of this Saturday, the number jumped up to 18,000, but I have no way of finding out using the search console reports why the jump happened or what are the new URLs that were added, the only sort mechanism is last crawled and they don't show up there. How long can I expect it to take for these remaining urls to also be removed from the index? Is there any way to expedite the process? I've submitted a 'new' sitemap several times, which (so far) has not helped. Is there any way to see inside the new GSC view why/how the number of valid URLs in the indexed doubled over one weekend?

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

Can I use duplicate content in different US cities without hurting SEO?
So, I have major concerns with this plan. My company has hundreds of facilities located all over the country. Each facility has it's own website. We have a third party company working to build a content strategy for us. What they came up with is to create a bank of content specific to each service line. If/when any facility offers that service, they then upload the content for that service line to that facility website. So in theory, you might have 10-12 websites all in different cities, with the same content for a service. They claim "Google is smart, it knows its content all from the same company, and because it's in different local markets, it will still rank." My contention is that duplicate content is duplicate content, and unless it is "localize" it, Google is going to prioritize one page of it and the rest will get very little exposure in the rankings no matter where you are. I could be wrong, but I want to be sure we aren't shooting ourselves in the foot with this strategy, because it is a major major undertaking and too important to go off in the wrong direction. SEO Experts, your help is genuinely appreciated!

Can a .ly domain rank in the United States?
Hello members. I have a question that I am seeking to confirm whether or not I am on the right track. I am interested in purchasing a .ly domain which is the ccTLD for Libya. The purpose of the .ly domain would be for branding purposes however at the same time I do not want to kill the websites ability to rank in Google.com (United States searches) because of this domain. Google does not consider .ly to be one of those generic ccTLDs like. io, .cc, .co, etc. that can rank and Bitly has also moved away from the .ly extension to a .com extension. Back in 2011 when there was unrest in Lybia, a few well known sites that utilized the .ly extension had their domains confiscated such as Letter.ly, Advers.ly and I think Bitly may have been on that list too however with the unrest behind us it is possible to purchase a .ly so being able to obtain one is not an issue. From what I can tell, I should be able to specify in Google Search Console that the website utilizing the .ly extension is a US based website. I can also do this with Google My Business and I will keep the Whois info public so the whois data can been seen as a US based website. Based on everything I just said do any of you think I will be OK if I were to register and use the .ly domain extension and still be able to rank in Google.com (US Searches). Confirmation would help me sleep better. Thanks in advance everyone and have a great day!!

What are Soft 404's and are they a problem
Hi, I have some old pages that were coming up in google WMT as a 404. These had links into them so i thought i'd do a 301 back to either the home page or to a relevant category or page. However these are now listed in WMT as soft 404's. I'm not sure what this means and whether google is saying it doesn't like this? Any advice welcomed.

Primary Domain or Redirect?
We are starting a new travel guide for a resort town. I have bought an expired domain with decent related links and PR (which seems to have survived the transfer (4 months ago). Beofre we launch the new site I am trying to decide if we should use this expired domain as the primary URL for the new site or just do a permanent redirect and buy a new domain that better matches the theme of the site. I am obviously concerned with starting from scatch with a new domain. I am confident we can build some good rellevant links in a short time but this space is very competetive. Any input would be greatly appreciated.

Migrating online store to subdomain using shopify and effects on seo and energy down the road for seo
I'm looking for some clarity... Looking at using Shopify for an existing online store that we have to migrate. Setting up the store with shopify means we will be using a subdomain such as shop.mywebsite.com instead of mywebsite.com/shop. The following are points to consider when responding The client currently has an online store, however it's a proprietary shopping store and CMS that has since gone defunct and they need to migrate to an alternative in order to survive online against new CMS systems that allow the site and its content to be better optimized. There is a lot of existing SEO done on the current site that we don't want to loose PR on. There is roughly 2000 products Client has a fixed budget, dealing with checkout issues, custom work and various other "bugs" seems to be easier controlled with Shopify...thus budget can be used more on content/strategy and migration We want to run the main site in Wordpress and are wanting to use Shopify since it supports a gateway, has great features and seems like it would allow us to get more bang for the buck and can focus more on the main site and content strategy and drive traffic to the subdomain store if needed Or main concern is the effort of migrating 2000+ products to shopify and the traffic and PR it gives the current site will have a negative effect on the main domain itself. Should we really be considering this path? The domain is diveidc.com One main benefit to the subdomain is the ability to clearly segment products from the service portion of the site in the analytics and focus 2 clear strategies and track it in a very defined manner. We're really on the fence with this...any thoughts are welcome.
