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.

Robots.txt allows wp-admin/admin-ajax.php
Hello, Mozzers!
Technical SEO | | AndyKubrin
I noticed something peculiar in the robots.txt used by one of my clients: Allow: /wp-admin/admin-ajax.php What would be the purpose of allowing a search engine to crawl this file?
Is it OK? Should I do something about it?
Everything else on /wp-admin/ is disallowed.
Thanks in advance for your help.

Subdomain or subfolder?
Hello, We are working on a new site. The idea of the site is to have an ecommerce shop, but the homepage will be a content page, basically a blog page.
Technical SEO | | pinder325
My developer wants to have the blog (home) page on a subdomain, so blog.example.com, because it will be easier to make a nice content page this way, and the the rest of the site will just be on the root domain (example.com). I'm just worried that this will be bad for our SEO efforts. I've always thought it was better to use a sub folder rather than a subdomain. If we get links to the content on the subdomain, will the link juice flow to the shop, on the root domain? What are your thoughts?0 -
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
Technical SEO | | lauralou82
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 -
Multiple robots.txt files on server
Hi! I have previously hired a developer to put up my site and noticed afterwards that he did not know much about SEO. This lead me to starting to learn myself and applying some changes step by step. One of the things I am currently doing is inserting sitemap reference in robots.txt file (which was not there before). But just now when I wanted to upload the file via FTP to my server I found multiple ones - in different sizes - and I dont know what to do with them? Can I remove them? I have downloaded and opened them and they seem to be 2 textfiles and 2 dupplicates. Names: robots.txt (original dupplicate)

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.

Robots.txt on http vs. https
We recently changed our domain from http to https. When a user enters any URL on http, there is an global 301 redirect to the same page on https. I cannot find instructions about what to do with robots.txt. Now that https is the canonical version, should I block the http-Version with robots.txt? Strangely, I cannot find a single ressource about this...

Googlebot does not obey robots.txt disallow
Hi Mozzers! We are trying to get Googlebot to steer away from our internal search results pages by adding a parameter "nocrawl=1" to facet/filter links and then robots.txt disallow all URLs containing that parameter. We implemented this late august and since that, the GWMT message "Googlebot found an extremely high number of URLs on your site", stopped coming. But today we received yet another. The weird thing is that Google gives many of our nowadays robots.txt disallowed URLs as examples of URLs that may cause us problems. What could be the reason? Best regards, Martin
