Will Links to one Sub-Domain on a Site hurt a different Sub-Domain on the same site by affecting the Quality of the Root Domain?
-
Hi,
I work for a SaaS company which uses two different subdomains on our site. A public for our main site (which we want to rank in SERPs for), and a secure subdomain, which is the portal for our customers to access our services (which we don't want to rank for) .
Recently I realized that by using our product, our customers are creating large amounts of low quality links to our secure subdomain and I'm concerned that this might affect our public subdomain by bringing down the overall Authority of our root domain.
Is this a legitimate concern? Has anyone ever worked through a similar situation?
any help is appreciated!

Thanks for the advise Carson!

Firstly, I wouldn't worry about your customers creating "low-quality links" unless your customers are exclusively spammers. Low authority links and spam links are two very different things in Google's eyes.
If the links point to pages that a user could not see without logging in, simply use a meta robots noindex to ensure the pages won't appear in search results. This isn't especially critical, since the page would be unlikely to appear in results anyway, but you can follow the best practice of blocking content behind a wall if you're worried about it.
If you do have a lot of customers running sites Google might consider spammy, let me know and we'll talk about it from there. Otherwise you don't need to worry.

Hi Nakul,
Thanks for the reply.
Sorry I wasn't a little more specific in my initial question. Anyhow our secure site is not at all the same as our public site. The secure site is used by our customers to access their accounts and use our applications. An example would be a click-to-call. If one of our customers uses our click to call service on every page of their website, then we will have several links from that customer's site back to our secure site. My concern is that this could be negatively impacting our public site since both use the same root domain.
Any thoughts on whether or not this could be a problem?
Thanks again for your help!

Are the URLs, pages/filenames 100% in sync between the secure subdomain and the main/public site ? If that's the case (and if it makes sense, you add a canonical on your secure.subdomain.com to public.subdomain.com pages). This way your secure.subdomain.com will not get indexed in the SERPS and will act as a 301 redirect.
P.S. Only do this if the pages are 100% in SYNC and the only difference is price etc. This way only 1 version of the pages get indexed. Users linking to your secure site will NOT get redirected, they will still see the secure site. But when the bots follow the link, they will see the canonical link as a strong directive not to index this page but your public equivalent of the same page.

Site links show spam
Hi folks, I'm working on a website that runs on WordPress and was not updated by the owner, this has resulted in a malware injection and now when you search the companies name in Google, the site links appear with words like Viagra, et al. I've seen this a number of times, so I went through the code and have removed all the malware. I presume I now have to wait for Google to recrawl the website and update the site links? Is there anything else I should be doing to speed up the process? Thank you 🙂

Will a 303 redirect hurt us?
Our membership based website is using a 303 redirect to handle the redirection of users back to the login page when those users try to access a page behind the logged in firewall. Said another way, if a user is not yet logged in, we redirect them to the login page using a 303 redirection. Unfortunately, Googlebot get this redirection too and after a recent audit, we're thinking this isn't the best way to handle this. For pages which require a user to login first, should we: A) index and 303 redirect to the login page (what we are currently doing) B) index and 302 redirect to the login page C) noindex those pages D) Remove any special treatment and let Google figure it out. Thanks in advance for your help! David

Is 301 redirecting all old URLS after a new site redesign to the root domain bad for SEO?
After a new site redesign ...would it hinder our rankings if we 301 redirected all old URLS that are returning 404 error codes to the root domain (home page) ? Would this be a good temporary solution until we are able to redirect the pages to the appropriate corresponding page? Thanks so much!

Are site wide links bad for web developers?
Like many web dev companies, we put an anchor text credit (varying the anchor text) in the footer of clients' sites. As it's a footer link, it's site wide. This strategy's been troubling me for a while and I've been anticipating a drop in our rankings ... especially in light of Penguin. But it hasn't happened. Any other developers our there taken a hit by having site wide links? anyone have any views on this? Anyone want to comment on the spurious and unlikely scenario that Google may recognise that web dev companies have always used site wide credits and may therefore be overlooking / not penalising them?

301 Redirect & Linking Root Domain Count
Howdy Mozzers! If I do a 301 redirect from a domain that say has 200 linking root domains, to a fresh domain will the fresh domain now (when updated) have a linking root domain count of 200? Also, is it beneficial or detrimental to do a 301 redirect for an unrelated website i.e. garden hose website, to a children's playgorund equipment website in order to capture the link juice? Best

How will a domain change affect my rankings?
My company will undergo a domain change in the next few months. Other than implementing 301 redirects, what else can I do to help the search engines realize the site has moved? What kind of impact on rankings can I expect to see? Thanks in advance!
