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

Is an iframe redirect on the same Domain bad for SEO
Good morning. We have a vendor that has created a landing page with content that we want to use. Because of the way we built the site, the only way to use the content is to create an i-frame. The i-frame is re-directingon the same Domain. Would we benefit from the SEO Content?

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.

Changing Brand and Domain Name - SEO Impacts
Hi everyone I'm hoping a few of you can help me out... We're an online-one retailer and we're currently looking at rebranding.
Intermediate & Advanced SEO | | piazza
This is for commercial reasons: Our current name is difficult for customers to spell It's not wholly representative of what we now offer We want to push offline and social marketing to help increase or DA In a nutshell, our current name implies 'cheap' and we're moving more upmarket.
Our DA is only 10, and a re-brand will make our brand more marketable.
A stronger brand and DA will help us climb up the rankings quickly - last year we ranked no 1 for a relatively competitive term before dropping a few places. In terms of current traffic: 30% is via SEO (we have a low DA but rank ok for certain phrases) 70% is via adwords We had our website redesigned last year and it performs well.
The idea is to have a new brand logo and colours and move to a new domain.
We will keep all our existing products and content. Please could anyone let me know the implications of this move?
What are potential pitfalls, and what will we need to do to alert Google?
I have read about 301 redirects, would these be required? As always, any help is very much appreciated. Many thanks Abs0 -
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

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.

Subdomain Blog Sitemap link - Add it to regular domain?
Example of setup:
Intermediate & Advanced SEO | | EEE3
www.fancydomain.com
blog.fancydomain.com Because of certain limitations, I'm told we can't put our blogs at the subdirectory level, so we are hosting our blogs at the subdomain level (blog.fancydomain.com). I've been asked to incorporate the blog's sitemap link on the regular domain, or even in the regular domain's sitemap. 1. Putting the a link to blog.fancydomain.com/sitemap_index.xml in the www.fancydomain.com/sitemap.xml -- isn't this against sitemap.org protocol? 2. Is there even a reason to do this? We do have a link to the blog's home page from the www.fancydomain.com navigation, and the blog is set up with its sitemap and link to the sitemap in the footer. 3. What about just including a text link "Blog Sitemap" (linking to blog.fancydomain.com/sitemap_index.html) in the footer of the www.fancydomain.com (adjacent to the text link "Sitemap" which already exists for the www.fancydomain.com's sitemap. Just trying to make sense of this, and figure out why or if it should be done. Thanks!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?
