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

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.

Will changing category URLs on site hurt SEO?
Hi Moz Community, We're looking to replace some URLs on our Wordpress site and I want to make sure we won't hurt our SEO with the changes. The site is lushpalm.com When we originally launched our site we created pages (which are linked to in our main menu) to essentially display our categories. We did this as a workaround because we didn’t like the URL to have the word “category” in it. Now we would like to make some changes and we want to make sure we’re not going to hurt our SEO in any way by accidentally duplicating content or otherwise. We want to fix our structure and now link to our category pages from our main menu, BUT we want to change the URL of the category page so that it doesn’t have “category” in it, essentially renaming it the name of the page currently linked to in our main menu. So basically, the category lushpalm.com/category/surf-trips, would be renamed with the URL lushpalm.com/surf-trips and the current page that is at lushpalm.com/surf-trips would be therefore replaced. My questions are: If we did this, would that mean that the previous “lushpalm.com/category/surf-trips” would cease to exist? Or is there some imprint of that out on the web? And if it is then would it re-direct to the new page? Would replacing the current page URL with a category hurt our current SEO in any way? Would this change cause any duplicate pages somehow? Thanks so much for your help!

Does it hurt your SEO to have an inaccessible directory in your site structure?
Due to CMS constraints, there may be some nodes in our site tree that are inaccessible and will automatically redirect to their parent folder. Here's an example: www.site.com/folder1/folder2/content, /folder2 redirects to /folder1. This would only be for the single URL itself, not the subpages (i.e. /folder1/folder2/content and anything below that would be accessible). Is there any real risk in this approach from a technical SEO perspective? I'm thinking this is likely a non-issue but I'm hoping someone with more experience can confirm. Another potential option is to have /folder2 accessible (it would be 100% identical to /folder1, long story) and use a canonical tag to point back to /folder1. I'm still waiting to hear if this is possible. Thanks in advance!

Do Q&A 's work for SEO
If I create a good community in my particular field on my SEO site and have a quality Q&A section like this etc (ripping of MOZ's idea here sorry, I hope it's ok) will the long term returns be worth the effort of creating and man ageing this. Is the user created content of as much use as I think it will be?

Include Cross Domain Canonical URL's in Sitemap - Yes or No?
I have several sites that have cross domain canonical tags setup on similar pages. I am unsure if these pages that are canonicalized to a different domain should be included in the sitemap. My first thought is no, because I should only include pages in the sitemap that I want indexed. On the other hand, if I include ALL pages on my site in the sitemap, once Google gets to a page that has a cross domain canonical tag, I'm assuming it will just note that and determine if the canonicalized page is the better version. I have yet to see any errors in GWT about this. I have seen errors where I included a 301 redirect in my sitemap file. I suspect its ok, but to me, it seems that Google would rather not find these URL's in a sitemap, have to crawl them time and time again to determine if they are the best page, even though I'm indicating that this page has a similar page that I'd rather have indexed.
