How do I list the subdomains of a domain?
-
Hi Mozers,
I am trying to find what subdomains are currently active on a particular domain. Is there a way to get a list of this information?
The only way I could think of doing it is to run a google search on;
site:example.com -site:www.example.com
The only issues with this approach is that a majority of the indexed pages exist on the non-www domain and I still have thousands of pages in the results (mainly from the non-www).
Is there another way to do it in Google? OR is there a server admin online tool that will tell me this information?
Cheers,
Dan

Really?? That's strange - if you PM me the domain, I can do a bit more digging.

Sadly, although this site is big (over 1000 pages), wolfram alpha doesn't offer the tab that suggests subdomain...
I checked it on a number of sites (seomoz, harvard etc ) and it worked well.
Any other ideas?

Thanks again,
Running this on my Mac, it allowed me to run NSLookup but when it came to listing the subdomains it advised me that 'ls' was not a valid command.

Go to Wolfram Alpha
-
Enter the domain without any subdomain (ie. wordpress.com)
-
In the 3rd result box, top right, push "subdomains."
-
When it opens, push "more" (top right of the box)
You'll get something like this:

Yeah, sorry, bit of a basic response! Well, if the server admin took any sort of standard security class then you won't be able to see the file.
You could try this method if it hasn't been secured though:

Hi Steven,
Thanks for the quick response, what I should have pointed out was that I am currently proposing a Strategy for this site and do not have access to it.
Any further thoughts?

Hi Dan,
The way to know for sure is to get a copy of the Start of Authority (SOA) file for the domain.
Can you ask your host or server admin for this?

Redirection of 100 domain to Main domain affects SEO?
Hi guys, An email software vendor managed by a different area of my company redirected 100 domains used for unsolicited email campaigns to my main domain. These domains are very likely to get blacklisted at some point. My SEO tool now is showing me all those domains as "linking" to my main site as do-follow links. The vendor states that this will not affect my main domain/website in any way. I'm highly concerned. I would appreciate your professional opinion about this. Thanks!!

301 Redirecting from domain to subdomain
We're taking on a redesign of our corporate site on our main domain. We also have a number of well established, product based subdomains. There are a number of content pages that currently live on the corporate site that rank well, and bring in a great deal of traffic, though we are considering placing 301 redirects in place to point that traffic to the appropriate pages on the subdomains. If redirected correctly, can we expect the SEO value of the content pages currently living on the corporate site to transfer to the subdomains, or will we be negatively impacting our SEO by transferring this content from one domain to multiple subdomains?

Blog subdomain not redirecting
Over the last few weeks I have been focused on fixing high and medium priority issues, as reported by the Moz crawler, after a recent transition to WordPress. I've made great progress, getting the high priority issues down from several hundred (various reasons, but many duplicates for things like non-www and www versions) to just five last week. And then there's this weeks report. For reasons I can't fathom, I am suddenly getting hundreds of duplicate content pages of the form http://blog.<domain>.com</domain> (being duplicates with the http://www.<domain>.com</domain> versions). I'm really unclear on why these suddenly appeared. I host my own WordPress site ie WordPress.org stuff. In Options / General everything refers to http://www.<domain>.com</domain> and has done for a number of weeks. I have no idea why the blog versions of the pages have suddenly appeared. FWIW, the non-www version of my pages still redirect to the www version, as I would expect. I'm obviously pretty concerned by this so any pointers greatly appreciated. Thanks. Mark

Do low quality subdomains affect the ranking performance/quality of a root domain?
Hi, Late last year the company I work for launched two new websites that, at the time, we believed were completely separate from our main website. The two new websites were set up externally and were not well-planned from an SEO perspective (LOTS of duplicate content) - hence, they have struggled to rank on Google. Since the launch of the new websites we have also noticed that our main website (that previously ranked very well) has suffered a decline in visitation and search engine rank. We initially attributed this to a number of factors, including the state of the market, and ramped up our SEO efforts (seeing minor improvement). We have since realised that these two new websites have been set up as subdomains of our main website, with MOZ displaying the same domain authority and root domain backlink profile. My question is, do poor quality subdomains affect the ranking performance of a root domain? I have not yet managed to find a definitive answer. Please let me know if more information is required - I am quite new to the whole SEO concept. Thanks! Amy

Using pictures from another domain
We are building several sites for several clients which will be using images from the manufacturer. Our dev team wants to insert the manufacturer's url for the images, instead of actually downloading the image and hosting on our server. There are thousands of images, so downloading images to our server will be time consuming, so we are looking for a shortcut.... however I'm concerned this will cause other issues. Is using manufactueresdomain.com/12345.jpg going to cause SEO issues? will this generate Google penalties? Since we are not able to control the image file name, we cannot optimize it. We will add Alt text and Title tag for each image, but the file name is random characters. How important is the file name for SEO?

Noindex, Nofollow to previous domain
Hi, My programmer recently did a horrible mistkae by adding noindex, nofollow to our website without me noticing for two days. At the same time he did it we bought a new domain and redirected the old domain to the new domain: The Old domain is: http://www.websitebuildersworld.com and the new one is: http://www.websiteplanet.com Now unfortunatly I didn't notice the noindex,nofollow when it was on the old domain and I redirected it to websiteplanet.com before I fixed the noindex, nofollow. I fixed the problem around 10 hours ago on the new domain (www.websiteplanet.com) but the old domain didn't get indexed back (yet), so for example if you search for WebsiteBuildersWorld in google you will not reach the homepage as google deleted it because of the noindex,nofollow. My question is:
Intermediate & Advanced SEO | | Ouzan
Do you think that it will be fixed and google will retrieve websitebuildersworld homepage to his search results and then redirect it to websiteplanet? Or because I redirected websitebuildersworld.com to websiteplanet.com before letting google crawling websitebuildersworld.com without the noindex,no follow it wouldn't get indexed again? I hope I explained the problem good enough. Looking forward for your valuable replies. Thanks.0 -
Hosting images on multiple domains
I'm taking the following from http://developer.yahoo.com/performance/rules.html "Splitting components allows you to maximize parallel downloads. Make sure you're using not more than 2-4 domains because of the DNS lookup penalty. For example, you can host your HTML and dynamic content on www.example.org and split static components between static1.example.org and static2.example.org" What I want to do is load page images (it's an eCommerce site) from multiple sub domains to reduce load times. I'm assuming that this is perfectly OK to do - I cannot think of any reason that this wouldn't be a good tactic to go with. Does anyone know of (or can think of) a reason why taking this approach could be in any way detrimental. Cheers mozzers.

Franchise sites on subdomains
I've been asked by a client to optimise a a webpage for a location i.e. London. Turns out that the location is actually a franchise of the main company. When the company launch a new franchise, so far they have simply added a new page to the main site, for example: mysite.co.uk/sub-folder/london They have so far done this for 10 or so franchises and task someone with optimising that page for their main keyword + location. I think I know the answer to this, but would like to get a back up / additional info on it in terms of ranking / seo benefits. I am going to suggest the idea of using a subdomain for each location, example: london.mysite.co.uk Would this be the correct approach. If you think yes, why? Many thanks,
