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?

Linking from & to in domains and sub-domains
What's the best optimised linking between sub-domains and domains? And every time we'll give website link at top with logo...do we need to link sub-domain also with all it's pages? If example.com is domain and example.com/blog is sub-domain or sub-folder... Do we need to link to example.com from /blog? Do we need to give /blog link in all pages of /blog? Is there any difference in connecting domains with sub-domains and sub-folders?

Too many backlinks from one domain?
I've been in the process of creating a tourism-based website for the state of Kansas. I'm a photographer for the state, and have inked a nice little side income to my day job as a web designer by selling prints from Kansas (along with my travels elsewhere). I'm still in the process of developing it, but it's at least at a point that I need to really start thinking about SEO factor of the amount of backlinks I have from it going back to my main photography website. The Kansas site is at http://www.kansasisbeautiful.com and my photography website is http://www.mickeyshannon.com. This tourism website will serve a number of purposes: To promote the state and show people it's not just a flat, boring place. To help promote my photography. The entire site is powered by my photography. To sell a book I'm planning to publish later this year/early next year of Kansas images. To help increase sales of photography prints of my work. What I'm worried about is the amount of backlinks I have going from the Kansas site to my photography site. Not to mention every image is hosted on my photography domain (no need to upload to two domains when one can serve the same purpose). I'm currently linking back to my site on most pages via a little "Like the Photos? Buy a print" link in the top right corner. In addition, when users get to the website map, all photo listings click back to a page on my photography site that they can purchase prints. And the main navigation also has a link for "Photos" that takes them to my Kansas photo galleries on my photography website as well. The question I have: Is it really bad SEO-wise to have anywhere from 1 to 10+ backlinks on every page from one domain (kansasisbeautiful.com) linking back to mickeyshannon.com? Would I be better served moving all of the content from kansasisbeautiful into a subdirectory on my photography site (mickeyshannon.com/kansas/) and redirecting the entire domain there? I haven't actually launched this website yet, so I'm trying to make the right call before pushing it to the public. Any advice would be appreciated!

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)?

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?

Subdomain for every us state?

I am not sure about is this a good idea? What is your opinion about it?

SEO value in multiple backlinks from same domain and from various sub-domains.
A site has a link to my site as one of their main tabs, which means whenever a user clicks through to another page within the site, my link - being a main tab - is there. This creates thousands of links from this site. How does Google treat this? Do we have a rough formula estimate. In other words, assume it creates 1,000 backlinks would the SEO value be around the same as if I had just 2 link total as a main tab, but on 2 different non-related sites? Or, does it actually count fully as 1,000 links? Links from various sub-domains. Several .EDU's are linking to my site. Different schools within the overall same university. Example: nursing.abc.edu links to my site, but so does business.abc.edu. For SEO does that count as much as if I had links from complete non-related universities, or would Google evaluate that these links are related (since same main domain) and that will discount any links more than 1 to some extent? If discounted, then what do we estimate the discount to be? thank yoyu

Merging Domains... Sub-domains, Directories or Seperate Sites?
Hello! I am hoping you can help me decide the best path to take here... A little background: I'm moving to a new company that has three old domains (the oldest is 10 years old), which get a lot of traffic from their e-letters. Until recently they have not cared about SEO. So the websites have some structural, coding, URL and other issues. The sites are indexed, but have a problem getting crawled and/or indexed for new content - haven't delved into this yet but am certain I will be able to fix any of these issues. These three domains are PR4, PR4, PR5 and contain hundreds of unique articles. Here's the question... They want to move these three sites **to their main company site (PR4) and create sub domains for each one. ** I am wondering if this is a good idea or not. I have merged sites before (creating categories and/or directories) and the end result is that the ONE big site, is much for effective than TWO smaller, less authoritative sites. But the sub domain idea is something I am unsure about from an SEO perspective. Should we do this with sub domains? Or do you think we should keep the sites separate? How do Panda and Penguin play into this? Thanks in advance for the help! SD P.S. I'm not a huge advocate in using PR as a measurement tool, but since I can't reveal the actual domains, I figured I would list it as a reference point.

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.
