Subdomain Removal in Robots.txt with Conditional Logic??
-
I would like to see if there is a way to add conditional logic to the robots.txt file so that when we push from DEV to PRODUCTION and the robots.txt file is pushed, we don't have to remember to NOT push the robots.txt file OR edit it when it goes live.
My specific situation is this:
I have www.website.com, dev.website.com and new.website.com and somehow google has indexed the DEV.website.com and NEW.website.com and I'd like these to be removed from google's index as they are causing duplicate content.
Should I:
a) add 2 new GWT entries for DEV.website.com and NEW.website.com and VERIFY ownership - if I do this, then when the files are pushed to LIVE won't the files contain the VERIFY META CODE for the DEV version even though it's now LIVE? (hope that makes sense)
b) write a robots.txt file that specifies "DISALLOW: DEV.website.com/" is that possible? I have only seen examples of DISALLOW with a "/" in the beginning...
Hope this makes sense, can really use the help! I'm on a Windows Server 2008 box running ColdFusion websites.

Here's how I dealt with a similar situation in the past.
Robots.txt on each of the dev subdomains and on the live domain. Dev subdomains robots.txt excluded the entire subdomain, and subdomains were verified in GWT and removed as needed.
Made live subdomain robots.txt read-only so it didn't get overwritten. Should have made dev subdomains robots.txt read-only as well, since they sometimes got refreshed with the live content (there was a UGC database that would occasionally get copied to a dev subdomain, and we'd have robots.txt get copied over too and dev subdomain indexed).
Set up a code monitor that checks the contents of all of the robots.txt daily and sends me an email if anything is changed.
Not perfect, but I was at least able to catch changes soon after they happened, and prevented a few changes.

you can't put logic in robots.txt and subdomains are seen as different sites, so you need to create separate robots.txt files for each subdomain and block them in their respective robots.txt files.
You'll need to also add the Google verification code and verify them, then in GWMT you can request to have the subdomain removed from Googles index, that's the fastest way.

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!

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

Google indexing despite robots.txt block
Hi This subdomain has about 4'000 URLs indexed in Google, although it's blocked via robots.txt: https://www.google.com/search?safe=off&q=site%3Awww1.swisscom.ch&oq=site%3Awww1.swisscom.ch This has been the case for almost a year now, and it does not look like Google tends to respect the blocking in http://www1.swisscom.ch/robots.txt Any clues why this is or what I could do to resolve it? Thanks!

Speed benefits from loading images from a subdomain
I have read that loading images from a subdomain of your site instead of the main domain will give you speed benefits on load time. Has anyone actually seen that to be the case? Thanks!

Are robots.txt wildcards still valid? If so, what is the proper syntax for setting this up?
I've got several URL's that I need to disallow in my robots.txt file. For example, I've got several documents that I don't want indexed and filters that are getting flagged as duplicate content. Rather than typing in thousands of URL's I was hoping that wildcards were still valid.

Best Way To Clean Up Unruly SubDomain?
Hi, I have several subdomains that present no real SEO value, but are being indexed. They don't earn any backlinks either. What's the best way of cleaning them up? I was thinking the following: 1. Verify them all in Webmaster Tools. 2. Remove all URLs from the index via the Removal Tool in WMT 3. Add site-wide no-index, follow directive. Also, to remove the URLs in WMT, you usually have to block the URLs via /robots.txt. If I'd like to keep Google crawling through the subdomains and remove their URLs, is there a way to do so?

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.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 -
Robots.txt and canonical tag
In the SEOmoz post - http://www.seomoz.org/blog/robot-access-indexation-restriction-techniques-avoiding-conflicts, it's being said - If you have a robots.txt disallow in place for a page, the canonical tag will never be seen. Does it so happen that if a page is disallowed by robots.txt, spiders DO NOT read the html code ?
