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

When creating a sub-domain, does that sub-domain automatically start with the DA of the main domain?
We have a website with a high DA and we are considering sub-folder or sub-domain. One of the great benefits of a sub-folder is that we know we get to keep the high DA, is this also the case for sub-domains? Also if you could provide any sources of information that specify this, I can't see to find anything!

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.

How will changing my website's page content affect SEO?
Our company is looking to update the content on our existing web pages and I am curious what the best way to roll out these changes are in order to maintain good SEO rankings for certain pages. The infrastructure of the site will not be modified except for maybe adding a couple new pages, but existing domains will stay the same. If the domains are staying the same does it really matter if I just updated 1 page every week or so, versus updating them all at once? Just looking for some insight into how freshening up the content on the back end pages could potentially hurt SEO rankings initially. Thanks!

How Can I Redirect an Old Domain to Our New Domain in .htaccess?
There is an old version of http://chesapeakeregional.com still floating around the web here: http://www.dev3.com.php53-24.dfw1-2.websitetestlink.com/component/content/category/20-our-services. Various iterations of this domain pop up when I do certain site:searches and for some queries as well (such as "Diagnostic Center of Chesapeake"). About 3 months ago the websitetestlink site had files and a fully functional navigation but now it mostly returns 404 or 500 errors. I'd like to redirect the site to our newer site, but don't believe I can do that in chesapeakeregional.com's .htaccess file. Is that so and would I need access to the websitetestlink .htaccess to forward the domain? Note* I (nor anyone else in our organization) has the login for the old site. The new site went live about 9 months before I arrived at the organization and I've been slowly putting the pieces together since arriving.

How can I get Bing to index my subdomain correctly?
Hi guys, My website exists on a subdomain (i.e. https://website.subdomain.com) and is being indexed correctly on all search engines except Bing and Duck Duck Go, which list 'https://www.website.subdomain.com'. Unfortunately my subdomain isn't configured for www (the domain is out of my control), so searchers are seeing a server error when clicking on my homepage in the SERPs. I have verified the site successfully in Bing Webmaster Tools, but it still shows up incorrectly. Does anyone have any advice on how I could fix this issue? Thank you!

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?

Does domain WhoIs Privacy affect SEO efforts?
Hi guys, I got a hopefully quick question. I am designing a site currently that is made up of many different domain names as part of a network. I've heard that Google will penalize however is linking is passed back and forth between these domains if the registrant information was the same. I have WhoIS privacy information on all the domains to stop telemarketers and spam as well as (hopefully stop Google from getting suspicious). I'm not doing anything bad or against Google rules but I can see how they might think that if I have a huge network and links are being passed between these. It's a friend of mine who owns like 2000 domains and he wants to put legitimate information on each one and rank them higher, it's an interesting concept but I won't go into to much detail. So my question is basically, does having WhoIS privacy on all these domains, will it affect me in anyway in the SEO process? Will google count the links passing back and forth as legitimate? Or might it get suspicious and think I am spam? Are there ways to see what server it's coming from? Should all these sites be on different servers? Any help is much appreciated!
