Robots.txt on subdomains
-
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!

Robots.txt in subfolders and hreflang issues
A client recently rolled out their UK business to the US. They decided to deploy with 2 WordPress installations: UK site - https://www.clientname.com/uk/ - robots.txt location: UK site - https://www.clientname.com/uk/robots.txt

US site - https://www.clientname.com/us/ - robots.txt location: UK site - https://www.clientname.com/us/robots.txt We've had various issues with /us/ pages being indexed in Google UK, and /uk/ pages being indexed in Google US. They have the following hreflang tags across all pages: We changed the x-default page to .com 2 weeks ago (we've tried both /uk/ and /us/ previously). Search Console says there are no hreflang tags at all. Additionally, we have a robots.txt file on each site which has a link to the corresponding sitemap files, but when viewing the robots.txt tester on Search Console, each property shows the robots.txt file for https://www.clientname.com only, even though when you actually navigate to this URL (https://www.clientname.com/robots.txt) you’ll get redirected to either https://www.clientname.com/uk/robots.txt or https://www.clientname.com/us/robots.txt depending on your location. Any suggestions how we can remove UK listings from Google US and vice versa?0 -
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

Should we move our documentation off subdomain?
Background: We have a popular open source e-commerce platform at http://spreecommerce.com. Right now the documentation is on http://guides.spreecommerce.com. We have "edge" documentation (for stuff that's not yet released) on http://edgeguides.spreecommerce.com but since it's largely duplicative we've told google not to index any of the edge stuff (via robots.txt). Question: Should we consider moving the guides under the main website under /docs or something like this? There's a ton of great content that people often read to learn more about the platform. Seems like we might be diluting our juice a bit to have it on a separate domain. WDYT?

Removing robots.txt on WordPress site problem
Hi..am a little confused since I ticked the box in WordPress to allow search engines to now crawl my site (previously asked for them not to) but Google webmaster tools is telling me I still have robots.txt blocking them so am unable to submit the sitemap. Checked source code and the robots instruction has gone so a little lost. Any ideas please?

OK to block /js/ folder using robots.txt?
I know Matt Cutts suggestions we allow bots to crawl css and javascript folders (http://www.youtube.com/watch?v=PNEipHjsEPU) But what if you have lots and lots of JS and you dont want to waste precious crawl resources? Also, as we update and improve the javascript on our site, we iterate the version number ?v=1.1... 1.2... 1.3... etc. And the legacy versions show up in Google Webmaster Tools as 404s. For example: http://www.discoverafrica.com/js/global_functions.js?v=1.1

http://www.discoverafrica.com/js/jquery.cookie.js?v=1.1
http://www.discoverafrica.com/js/global.js?v=1.2
http://www.discoverafrica.com/js/jquery.validate.min.js?v=1.1
http://www.discoverafrica.com/js/json2.js?v=1.1 Wouldn't it just be easier to prevent Googlebot from crawling the js folder altogether? Isn't that what robots.txt was made for? Just to be clear - we are NOT doing any sneaky redirects or other dodgy javascript hacks. We're just trying to power our content and UX elegantly with javascript. What do you guys say: Obey Matt? Or run the javascript gauntlet?0 -
Microsite on subdomain vs. subdirectory
Based on this post from 2009, it's recommended in most situations to set up a microsite as a subdirectory as opposed to a subdomain. http://www.seomoz.org/blog/understanding-root-domains-subdomains-vs-subfolders-microsites. The primary argument seems to be that the search engines view the subdomain as a separate entity from the domain and therefore, the subdomain doesn't benefit from any of the trust rank, quality scores, etc. Rand made a comment that seemed like the subdomain could SOMETIMES inherit some of these factors, but didn't expound on those instances. What determines whether the search engine will view your subdomain hosted microsite as part of the main domain vs. a completely separate site? I read it has to do with the interlinking between the two.

Should I set up a disallow in the robots.txt for catalog search results?
When the crawl diagnostics came back for my site its showing around 3,000 pages of duplicate content. Almost all of them are of the catalog search results page. I also did a site search on Google and they have most of the results pages in their index too. I think I should just disallow the bots in the /catalogsearch/ sub folder, but I'm not sure if this will have any negative effect?
