      Hi guys!

      I keep reading conflicting information on this and it's left me a little unsure. Am I right in thinking that a website with a subdomain of shop.sitetitle.com will share the same robots.txt file as the root domain?

        That's about as comprehensive an answer as I could have hoped for. Thanks Ryan, really appreciated.

          Mostly no.  I say 'mostly' because a lot of times when you look at a site using www and no-www if both of those work they're almost always pulling files from the same location (hence the warnings around duplicate content), so both www.domain.com/robots.txt and domain.com/robots.txt are going to work.  This is the dominant example of a subdomain sharing a robots.txt file. However, on domains that are set up as their own subdomains they have different robots.txt.  Take a look at the many differences between subdomain1-1000.wordpress.com/robots.txt vs wordpress.com/robots.txt.  If you set up a subdomain that isn't just a reflection of your root domain, then you'll need to create a robots.txt file as well. Cheers!

            Are subdomains a good seo strategy for a multistore e-commerce?

            Hi there I'm wondering what is the best strategy to work with multi-stores on magento: to use or not to use subdomains? Suppose we have the www.website.com and we configure it to use multistore. The url base will not have the store id on it so it will not be like www.website.com/store1 and www.website.com/store2. It will simply rely on the user session so if we have two categories for each store it will acces using: www.website.com/category1 (for store 1) www.website.com/category2 (for store 2) The homepage will allways be set on www.website.com so we should have a single page for several "home pages" (depending on the user session / store he is accessing). I guess this is not a good option if we want to rank for different keywords (for each store). So I was wondering if it is a good solution to set: store1.website.com store2.website.com This way we have 2 "home pages" each one able to rank. Does it make sense? Is it good or bad for seo? Another option I was considering was: www.website.com (for store 1) store2.website.com (for store 2) store3.website.com (for store 3) www.website.com/blog (for blog) Can this work? Good or bad for seo? best regards

            Is there any benefit in using a subdomain redirected to a single page?

            For example if we have a domain www.bobshardware.com.au and we setup a subdomain sydneysupplies.bobshardware.com.au and then brisbanescrewdrivers.bobshardware.com.au and used those in ad campaigns. Each subdomain being redirected back to a single page such as bobshardware.com.au/brisbane-screw-drivers  etc. Is there a benefit ? Cheers

            Removed Subdomain Sites Still in Google Index

            Hey guys, I've got kind of a strange situation going on and I can't seem to find it addressed anywhere.  I have a site that at one point had several development sites set up at subdomains.  Those sites have since launched on their own domains, but the subdomain sites are still showing up in the Google index.  However, if you look at the cached version of pages on these non-existent subdomains, it lists the NEW url, not the dev one in the little blurb that says "This is Google's cached version of www.correcturl.com."  Clearly Google recognizes that the content resides at the new location, so how come the old pages are still in the index?  Attempting to visit one of them gives a "Server Not Found" error, so they are definitely gone. This is happening to a couple of sites, one that was launched over a year ago so it doesn't appear to be a "wait and see" solution. Any suggestions would be a huge help.  Thanks!!

            Blocked jquery in Robots.txt, Any SEO impact?

            I've heard that Google is now indexing links and stuff available in javascript and jquery. My webmastertools is showing that some links are blocked in robots.txt of jquery. Sorry I'm not a developer or designer. I want to know is there any impact of this on my SEO? and also how can I unblock it for the robots? Check this screenshot: http://i.imgur.com/3VDWikC.png

            Robots.txt and Multiple Sitemaps

            Hello, I have a hopefully simple question but I wanted to ask to get a "second opinion" on what to do in this situation. I am working on a clients robots.txt and we have multiple sitemaps. Using yoast I have my sitemap_index.xml and I also have a sitemap-image.xml I do put them in google and bing by hand but wanted to have it added into the robots.txt for insurance. So my question is, when having multiple sitemaps called out on a robots.txt file does it matter if one is before the other? From my reading it looks like you can have multiple sitemaps called out, but I wasn't sure the best practice when writing it up in the file. Example: User-agent: * Disallow: Disallow: /cgi-bin/ Disallow: /wp-admin/ Disallow: /wp-content/plugins/ Sitemap: http://sitename.com/sitemap_index.xml Sitemap: http://sitename.com/sitemap-image.xml Thanks a ton for the feedback, I really appreciate it! :) J

            Staging & Development areas should be not indexable (i.e. no followed/no index in meta robots etc)

            Hi I take it if theres a staging or development area on a subdomain for a site, who's content is hence usually duplicate then this should not be indexable i.e. (no-indexed & nofollowed in metarobots) ? In order to prevent dupe content probs as well as non project related people seeing work in progress or finding accidentally in search engine listings ? Also if theres no such info in meta robots is there any other way it may have been made non-indexable, or at least dupe content prob removed by canonicalising the page to the equivalent page on the live site ? In the case in question i am finding it listed in serps when i search for the staging/dev area url, so i presume this needs urgent attention ? Cheers Dan

            Do knowledge base plugins on a subdomain have seo benefit?

            Hi SEO Moz, We want to use a knowledge base plugin (cheaper & faster than building it ourselves) where we can have Q&As for our website. We want this to help with our SEO by adding in our keyterms that we want to rank for. We've looked into TenderApp & Get Satisfaction which look like good solutions - however, as they're both on a sub-domain do we get any seo benefit from this? When people link to our knowledge base, will this help our website at all - or is the benefit going to go to TenderApp/Get Satisfaction? For instance - Our website URL is http://widget.products.com The KB URL is http://widgetsupport.products.com If the above plugin is not a good solution, is there anything else that is better? Any help will be greatly appreciated!! Thanks.
