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.

Role of Robots.txt and Search Console parameters settings
Hi, wondering if anyone can point me to resources or explain the difference between these two. If a site has url parameters disallowed in Robots.txt is it redundant to edit settings in Search Console parameters to anything other than "Let Googlebot Decide"?

Is there a limit to how many URLs you can put in a robots.txt file?
We have a site that has way too many urls caused by our crawlable faceted navigation. We are trying to purge 90% of our urls from the indexes. We put no index tags on the url combinations that we do no want indexed anymore, but it is taking google way too long to find the no index tags. Meanwhile we are getting hit with excessive url warnings and have been it by Panda. Would it help speed the process of purging urls if we added the urls to the robots.txt file? Could this cause any issues for us? Could it have the opposite effect and block the crawler from finding the urls, but not purge them from the index? The list could be in excess of 100MM urls.

Should we remove category paths for better SEO?
We're looking to build some serious content and capitalise on long-tail keyword traffic for our sub-category pages, example for targeted keyword "designer dining tables". Example of current link: www.website.com/designer-furniture/designer-dining-tables.html Would removing the category paths help? Example result - www.website.com/designer-dining-tables More user friendly URLs and better for SEO would you suggest? The only problem is, if we removed the paths would this have a hit on our traffic? Any advice would be much appreciated. We are using Magento platform.

Google insists robots.txt is blocking... but it isn't.
I recently launched a new website. During development, I'd enabled the option in WordPress to prevent search engines from indexing the site. When the site went public (over 24 hours ago), I cleared that option. At that point, I added a specific robots.txt file that only disallowed a couple directories of files. You can view the robots.txt at http://photogeardeals.com/robots.txt Google (via Webmaster tools) is insisting that my robots.txt file contains a "Disallow: /" on line 2 and that it's preventing Google from indexing the site and preventing me from submitting a sitemap. These errors are showing both in the sitemap section of Webmaster tools as well as the Blocked URLs section. Bing's webmaster tools are able to read the site and sitemap just fine. Any idea why Google insists I'm disallowing everything even after telling it to re-fetch?

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/

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

Why has Google removed meta descriptions from SERPS?
One of my clients' sites has just been redesigned with lots of new URLs added. So the 301 redirections have been put in place and most of the new URLs have now been indexed. BUT Google is still showing all the old URLs in the SERPS and even worse it only displays the title tag. The meta description is not shown, no rich snippet, no text, nothing below the title. This is proving disastrous as visitors are not clicking on a result with no description. I have to assume its got something to do with the redirection, but why is it not showing the descriptions? I've checked the old URLs and he meta description is definitely still in the code, but Google is choosing not to show it. I've never seen this before so I'm struggling for an answer. I'd like to know why or how this is happening, and if it can be resolved. I realise that this may be resolved when Google stops showing all the old URLs but there's no telling how long that will take (can it be speeded up?)
