I have two robots.txt pages for www and non-www version. Will that be a problem?
-
There are two robots.txt pages. One for www version and another for non-www version though I have moved to the non-www version.

It wont affect your SEO, you just don;t need the the non-https version

Hi ramb,
Short answer: No, it won't affect your ability to rank in Google. Unless both sites (non-www and www version) compete for the same search term and one of them isn't blocked in the correspondent robots.txt file.
If you can, make sure to have a redirection rule so as everything in the non-www goes to the www.
It bugs me why aren't you redirecting the complete non-www to the www version.
Two possibilities come to my mind:- You can't redirect the whole non-www due to some app or technical need.
In this case, both versions, if accessible to Google, will be treated as different sites. Thus, you must be sure that both robots file are correct for the given subdomain. - You have a separate website, which contains different content from the www version (this usually happens with subdomains with different page types, such as products.abc.com and categories.abc.com)
In this case, please be sure that you know what you want to be blocked and have each robots.txt file in their subdomain.
Keep in mind that Robots file only controls where you don't want googlebot to access in the public version of your website. When a certain page or group of pages are blocked in robots.txt, google won't access them anymore thus not knowing if that page has what it needs to rank for any given search term. Google might rank lower and users will see a note in search results, leading to a lower CTR.
Hope it helps.
Best Luck.

Are you redirecting everything on www to non-www? If so, you don't really need a robots.txt to be served for the www subdomain. Google will ignore the original robots.txt file if it is given a 301 anyway.

Hi Gatson
Thank you for your response. Currently, www version of the site is redirected to non-www version, which is the primary(or root) domain.
But the problem is, I have 2 robots.txt files running for the same site. i.e. same robots.txt file loads on both www and non-www version. (Example https://www.abc.com/robots.txt and https://abc.com/robots.txt).
Does it affect my site's SEO ??
Should I redirect www-version of the file to non-www version?
Your feedback will be highly appreciated.Thank you,
R.

Hi ramb,
It's totally fine to have different robots.txt files for different subdomains.
Thus said, http://domain.com and http://www.domain.com are different subdomains. Consider the one with non-www as the full root domain.In case it is needed, here you have Google's official resource about robots.txt:

Best luck.

Crawl solutions for landing pages that don't contain a robots.txt file?
My site (www.nomader.com) is currently built on Instapage, which does not offer the ability to add a robots.txt file. I plan to migrate to a Shopify site in the coming months, but for now the Instapage site is my primary website. In the interim, would you suggest that I manually request a Google crawl through the search console tool? If so, how often? Any other suggestions for countering this Meta Noindex issue?

Best Practice for www and non www
How is the best way to handle all the different variations of a website in terms of www | non www | http | https? In Google Search Console, I have all 4 versions and I have selected a preference. In Open Site Explorer I can see that the www and non www versions are treated differently with one group of links pointing to each version of the same page. This gives a different PA score. eg. http://mydomain.com DA 25 PA 35 http://www.mydomain.com DA 19 PA 21 Each version of the home page having it's only set of links and scores. Should I try and "consolidate" all the scores into one page? Should I set up redirects to my preferred version of the website? Thanks in advance

Home Page Ranking Instead of Service Pages
Hi everyone! I've noticed that many of our clients have pages addressing specific queries related to specific services on their websites, but that the Home Page is increasingly showing as the "ranking" page. For example, a plastic surgeon we work with has a page specifically talking about his breast augmentation procedure for Miami, FL but instead of THAT page showing in the search results, Google is using his home page. Noticing this across the board. Any insights? Should we still be optimizing these specific service pages? Should I be spending time trying to make sure Google ranks the page specifically addressing that query because it SHOULD perform better? Thanks for the help. Confused SEO :/, Ricky Shockley

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.

Adding multi-language sitemaps to robots.txt
I am working on a revamped multi-language site that has moved to Magento. Each language runs off the core coding so there are no sub-directories per language. The developer has created sitemaps which have been uploaded to their respective GWT accounts. They have placed the sitemaps in new directories such as: /sitemap/uk/sitemap.xml /sitemap/de/sitemap.xml I want to add the sitemaps to the robots.txt but can't figure out how to do it. Also should they have placed the sitemaps in a single location with the file identifying each language: /sitemap/uk-sitemap.xml /sitemap/de-sitemap.xml What is the cleanest way of handling these sitemaps and can/should I get them on robots.txt?

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 -
Robots.txt file getting a 500 error - is this a problem?
Hello all! While doing some routine health checks on a few of our client sites, I spotted that a new client of ours - who's website was not designed built by us - is returning a 500 internal server error when I try to look at the robots.txt file. As we don't host / maintain their site, I would have to go through their head office to get this changed, which isn't a problem but I just wanted to check whether this error will actually be having a negative effect on their site / whether there's a benefit to getting this changed? Thanks in advance!
