    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!

          Moving E-Commerce Store to Subdomain?

          Hi all, We have a customer who currently uses Square for their in-store point-of-sale system as well as for their e-commerce website. From my understanding, a Square site is a watered-down version of Weebly, and is proving to be highly restrictive from an SEO and content structuring standpoint. It's been an uphill battle to try and get traction for their site in SERPs. Would it be a bad idea to move the entire Square online store to a subdomain, and install WordPress on the root domain? This way their online store would remain as-is, but the primary pages on the site would be on WordPress which would give us a lot more control over the content. I just want to make sure this doesn't negatively impact their SEO. Thanks!

          Google Search console says 'sitemap is blocked by robots?

          Google Search console is telling me "Sitemap contains URLs which are blocked by robots.txt." I don't understand why my sitemap is being blocked? My robots.txt look like this: User-Agent: *
          Disallow: Sitemap: http://www.website.com/sitemap_index.xml It's a WordPress site, with Yoast SEO installed. Is anyone else having this issue with Google Search console? Does anyone know how I can fix this issue?

          Removing site subdomains from Google search

          Hi everyone, I hope you are having a good week? My website has several subdomains that I had shut down some time back and pages on these subdomains are still appearing in the Google search result pages. I want all the URLs from these subdomains to stop appearing in the Google search result pages and I was hoping to see if anyone can help me with this. The subdomains are no longer under my control as I don't have web hosting for these sites (so these subdomain sites just show a default hosting server page). Because of this, I cannot verify these in search console and submit a url/site removal request to Google. In total, there are about 70 pages from these subdomains showing up in Google at the moment and I'm concerned in case these pages have any negative impacts on my SEO. Thanks for taking the time to read my post.

          Robots txt. in page with 301 redirect

          We currently have a a series of help pages that we would like to disallow from our robots txt. The thing is that these help pages are located in our old website, which now has a 301 redirect to current site. Which is the proper way to go around? 1- Add the pages we want to disallow to the robots.txt of the new website? 2- Break the redirect momentarily and add the pages to the robots.txt of the old one? Thanks

          Subdomain as News Section instead of Source in Google News?

          Hi, trying to dig into Google News for a large site, mostly containing news.
          The structure of the site network is subdomain.domain.se, and each subdomain has it's own brand with it's own news: x.domain.se
          y.domain.se
          z.domain.se
          etc... Each brand/subdomain is more or less to equate with its own subjectfield/section. In Google News every subdomain is configured with it's own Site Source url, but also having the set up with one section with the same url. It seems like they're getting conflicts in Google News, Google can't always figure out which news article to which brand. Example: an article owned by brand A, but it is sometimes happens that articles getting labeled as brand B in the news SERP, though the link takes you correctly to brand A. I am thinking that this config in News Publisher Center may be a problem? Anyone having any thoughts if that would be better if we delete all source urls except for domain.se-brand and then put all the other subdomains as sections? www.domain.se x.domain.se y.doamin.se z.domain.se Any smart thoughts on this one? Or anything else that could make this wrong labeling (all content included images are hosted in same domain for example). Regards,
          Magnus

          Robots.txt to disallow /index.php/ path

          Hi SEOmoz, I have a problem with my Joomla site (yeah - me too!). I get a large amount of /index.php/ urls despite using a program to handle these issues. The URLs cause indexation errors with google (404). Now, I fixed this issue once before, but the problem persist. So I thought, instead of wasting more time, couldnt I just disallow all paths containing /index.php/ ?. I don't use that extension, but would it cause me any problems from an SEO perspective? How do I disallow all index.php's? Is it a simple: Disallow: /index.php/

          Starting a new product, should we use new domain or subdomain

          I'm working with a company that has a high page rank on it's main domain and is looking to launch a new business / product offering.  They are evaluating either creating a subdomain or launching a brand new domain.  In either case, their current site will link contextually to the new site.  Is there one method that would be better for SEO than the other? The new business / product is related to the main offering, but may appeal to different / new customers.  The new business / product does need it's own homepage and will have a different conversion funnel than the existing business.
