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?

Should I use the on classified listing pages that have expired?
We have went back and forth on this and wanted to get some outside input. I work for an online listing website that has classified ads on it. These ads are generated by companies on our site advertising weekend events around the country. We have about 10,000 companies that use our service to generate their online ads. This means that we have thousands of pages being created each week. The ads have lots of content: pictures, sale descriptions, and company information. After the ads have expired, and the sale is no longer happening, we are currently placing the in the heads of each page. The content is not relative anymore since the ad has ended. The only value the content offers a searcher is the images (there are millions on expired ads) and the descriptions of the items for sale. We currently are the leader in our industry and control most of the top spots on Google for our keywords. We have been worried about cluttering up the search results with pages of ads that are expired. In our Moz account right now we currently have over 28k crawler warnings alerting us to the being in the page heads of the expired ads. Seeing those warnings have made us nervous and second guessing what we are doing. Does anybody have any thoughts on this? Should we continue with placing the in the heads of the expired ads, or should we be allowing search engines to index the old pages. I have seen websites with discontinued products keeping the products around so that individuals can look up past information. This is the closest thing have seen to our situation. Any help or insight would be greatly appreciated! -Matt

Domain dominance
I've just started to work for a company who've purchased masses of domains with every conceivable permutation based on all their products with every extension possible e.g .biz . eu. .net (including .co.uk and .com of course). I have two questions: 1. Is it worth keeping all these (they want to add more) domains or let them expire? 2. All the purchased domains are online - is there any point (they redirect with a 301)?

Merging two different domains - subdomain or subfolder?
My company has two sites on different domains. We are considering merging the sites into one and keeping only the dominant domain. The dominate site is already a sub-domain of a larger organization so the new sub-domain would be two levels deep. I realize this is a little abstract so below is an example Dominant company site: company.root-domain.com Secondary company site: other-root-domain.com When they merge, everything will be on company.root-domain.com. Should it be other.company.root-domain.com or company.root-domain.com/other Note: The other site has several hundred pages. Both sites have strong authority and link profiles. I want to maintain as much of the value on the other site as possible with the merge.

XML Sitemap on another domain
Hi, We've rebuilt our website and created a better sitemap index structure. There's a good chance that we not be able to append the XML files to existing site for technical reasons (don't get me started). I'm reaching out because I'm wondering if can we place the XML files on another website or subdomain? I know this is not best practice and probably very grey but I'm looking for alternatives. If there answer is DON'T DO IT let me know too. Thx

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 -
Use of subdomains, subdirectories or both?
Hello, i would like your advice on a dilemma i am facing. I am working a new project that is going to release soon, thats a network of users with personal profiles seperated in categories for example lets say the categories are colors. So let say i am a member and i belong in red color categorie and i got a page where i update my personal information/cv/resume as well as a personal blog thats on that page. So the main site is giving the option to user to search for members by the criteria of color. My first idea is that all users should own a subdomain (and this is how its developed so far) thats easy to use and since the domain name is really small (just 3 letters) i believe subdomain worth since personal site will be easy to remember. My dilemma is should all users own a subdomain, a subdirectory or both and if both witch one should be the canonical? Since it said that search engines treat subdomains as different stand-alone sites, whats best for the main site? to show multiple search results with profiles in subdomains or subdirectories? What if i use both? meaning in search results i use search directory url for each profile while same time each profile owns a subdomains as well? and if so which one should be the canonical? Thanks in advance, C

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.

Should we stream videos from a subdomain or subfolder?
This is causing some hand-wrangling and I need some help. Let's say we were developing rich video content for our products and our agency is hosting the content on a new external server. There are already plans to link to these videos from product detail pages, category pages, and landing pages on our main website: www.example.com. Would it be better to create a new subdomain or to use a subfolder with a reverse proxy technique for this video content? It's not truly a microsite and will not have a gallery page to navigate the various videos. For example, would it be better to use this: video.example.com/ ...or this (executed with a reverse proxy😞 www.example.com/video/ Of course, regardless of whether this new content will live on a subdomain or within a subfolder, we plan on creating a video Sitemap using guidance from Justin Hammack in this terrific post.
