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

Why some domains and sub-domains have same DA, but some others don't?
Hi I noticed for some blog providers in my country, which provide a sub-domian address for their blogs. the sub-domain authority is exactly as the main domain. Whereas, for some other blog providers every subdomain has its different and lower authority. for example "ffff.blog.ir" and "blog.ir" both have domain authority of 60. It noteworthy to mention that the "ffff.blog.ir" does not even exist! This is while mihanblog.com and hfilm.mihanblog.com has diffrent page authority.

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 you allow an auto dealer's inventory to be indexed?
Due to the way most auto dealership website populate inventory pages, should you allow inventory to be indexed at all? The main benefit us more content. The problem is it creates duplicate, or near duplicate content. It also creates a ton of crawl errors since the turnover is so short and fast. I would love some help on this. Thanks!

Can using nofollow on magento layered navigation hurt?
Howdy Mozzers! We would like to use no follow, no index on our magento layered navigation pages after any two filters are selected. (We are using single filter pages as landing page, so we would liked them indexed) Is it ok to use nofollow, noindex on these filter pages? Are there disadvantages of using nofollow on internal pages? Matt mentioned refraining from using nofollow internally https://www.youtube.com/watch?v=4SAPUx4Beh8 But we would like to conserve crawling bandwidth and PR flow on potentially 100's of thousands of irrelevant/duplicate filter pages.

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?
