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!

Moving from a subdomain to subfolder
Hello, I am currently working on a site that is leveraging multiple subdomains. I wanted to see if it suggested to migrate them into subfolders. One of the subdomains is a .shop and the other is location specific. Thanks, T

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

I accidentally blocked Google with Robots.txt. What next?
Last week I uploaded my site and forgot to remove the robots.txt file with this text: User-agent: * Disallow: / I dropped from page 11 on my main keywords to past page 50. I caught it 2-3 days later and have now fixed it. I re-imported my site map with Webmaster Tools and I also did a Fetch as Google through Webmaster Tools. I tweeted out my URL to hopefully get Google to crawl it faster too. Webmaster Tools no longer says that the site is experiencing outages, but when I look at my blocked URLs it still says 249 are blocked. That's actually gone up since I made the fix. In the Google search results, it still no longer has my page title and the description still says "A description for this result is not available because of this site's robots.txt – learn more." How will this affect me long-term? When will I recover my rankings? Is there anything else I can do? Thanks for your input! www.decalsforthewall.com

Should I block robots from URLs containing query strings?
I'm about to block off all URLs that have a query string using robots.txt. They're mostly URLs with coremetrics tags and other referrer info. I figured that search engines don't need to see these as they're always better off with the original URL. Might there be any downside to this that I need to consider? Appreciate your help / experiences on this one. Thanks Jenni

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?

Best geotargeting strategy: Subdomains or subfolders or country specific domain
How have the relatively recent changes in how G perceives subdomains changed the best route to onsite geotargeting i.e. not building out new country specific sites on country specific and hosted domains and instead developing sub-domains or sub-folders and geo-targeting those via webmaster tools ? In other words, given the recent change in G perception, are sub-domains now a better option than a sub-folder or is there not much in it ? Also if client has a .co.uk and they want to geo-target say France, is the sub-domain/sub-folder route still an option or is the .co.uk still too UK specific, and these options would only work using a .com ? In other words can sites on country specific domains (.co.uk , .fr, .de etc etc) use sub-folders or domains to geo-target other countries or do they have no option other than to develop new country specific (domains/hosting/language) websites ? Any thoughts regarding current best practice in this regard much appreciated. I have seen last Febs WBF which covers geotargeting in depth but the way google perceives subdomains has changed since then Many Thanks Dan

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.
