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

Do bulk 301 redirects hurt seo value?
We are working with a content based startup that needs to 301 redirect a lot of its pages to other websites. Will give you an example to help you understand. If we assume this is the startups domain and URL structure www.ourcompany.com/brand1/article What they want to do is do a 301 redirect of www.ourcompany.com/brand1/ to www.brand1.com I have never seen 301 as a problem to SEO or link juice. But in this case where all the major URLs are getting redirected to other sites i was wondering if it would have a negative effect. Right now they have just 20-30 brands but they are planning to hit a couple of hundreds this year.

SEO'ing a sports advice website
Hi Team Moz, Despite being in tech/product development for 10+ years, I'm relatively new to SEO (and completely new to this forum) so was hoping for community advice before I dive in to see how Google likes (or perhaps doesn't) my soon to be built content. I'm building a site (BetSharper, an early-stage work in progress) that will deliver practical, data orientated predictive advice prior to sporting events commencing. The initial user personas I am targeting would need advice on specific games so, as an example, I would build a specific page for the upcoming Stanley Cup Game 1 between the Capitals and the Tampa Bay Lighting. I'm in the midst of keyword research and believe I have found some easier to achieve initial keywords (I'm realistic, building my DA will take time!) that include the team names but don't reference dates or state of the tournament. The question is, hypothetically if I ranked for this page for this sporting event this year, would it make sense to refresh the same page with 2019 matchup content when they meet again next year, or create a new page? I am assuming I would be targeting the same intended keywords but wondering if I get google credit for 2018 engagement post 2019 refresh. Or should I start fresh with a new page and specifically target keywords afresh each time? I read some background info on canonical tabs but wasn't sure if it was relevant in my case. I hope I've managed to articulate myself on what feels like an edge case within the wonderful world of SEO. Any advice the community delivers would be much appreciated...... Kind Regards James.

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

What happens to a domain in SERPs when it's set to redirect to another?
We have just acquired a competing website and are wondering whether to leave it running as is for now, or set the domain to redirect to our own site. If we set up this redirect, what would happen to the old site in Google SERPs? Would the site drop off from results? If so, would we capture this new search traffic or is it a free for all and all sites compete for the search traffic as normal? Thanks in advance. Paul

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

Can I dissavow links on a 301'd website?
So we are performing link removal for a client on his old website (A), which is being 301 redirected to his new website (B). We have identified toxic links on site A and are removing, once complete we will undo the current 301, confirm a new GWT account for website A, and then submit the disavow report. We would then like to reapply the 301 redirect to site B while we are waiting for Google to process the disavow report, the logic being we can retain some current rankings on site B while waiting for the disavow to process on site A. Has anyone had experience with this method? I foresee some potential issues here but am interested to here from others on this. Thanks!

Can you redirect specific sub domain URLs?
ello! We host our PDFs, Images, CSS all in a sub domain. For the question, let's call this sub.cyto.com. I've noticed a particular PDF doing really well, infact it has gathered valuable external links from high authoritative sites. To top it off, it gets good visits. I've been going back and forth with our developers to move this PDF to a subfolder structure.
Intermediate & Advanced SEO | | Bio-RadAbs
For example: www.cyto.com/document/xxxx.pdf In my perspective, if I move this and set up a permanent redirect, then all the external links the PDF gathered, link juice and future visits will be attributed to the main website. Since the PDF is existing in the subdomain, I can't even track direct visits nor get the link juice. It appears in top position of Google as well. My developer says it is better to keep images, pdf, css in the subdomain. I see his point and an idea I have is to: convert the pdf to a webpage. Set up a 301 redirect from the existing subdomain to this webpage Upload the pdf with a new name and link to it from the webpage, so users can download if they choose to. This should give me the existing rank juice. However, my question is whether you can set up a 301 redirect for just a single subdomain URL to a folder structure URL? sub.cyto.com/xxx.pdf to www.cyto.com/document/xxxx.pdf?0 -
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?
