      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...

          Good point with the backlinks! Currently, both robots.txt files are open and google does not seem to have canonicalization problems so far. So it makes sense to leave it this way anyways... Thanks Thomas!

            "Now that https is the canonical version, should I block the http-Version with robots.txt?"

            Absolutely not GWT will handel all of it think about backlinks both https:// & http:// urls you will not want to lose the flow of link juice that you would cut off

            Remake robost.txt with

            http://www.internetmarketingninjas.com/seo-tools/robots-txt-generator/

            But use https:// for the xml sitemap.

              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?

              Robot.txt : How to block a specific file type in several subdirectories ?

              Hello everyone ! I need help setting up a robot.txt. I'm trying to block all pdf files in particular directories so I'm using this command. In the example below the line is blocking all .gif in the entire site. Block files of a specific file type (for example, .gif) | Disallow: /*.gif$ 2 questions : Can I use this command to specify one particular directory in which I want to block pdf files ? Will this line be recognized by googlebots ? Disallow: /fileadmin/xxxxxxx/xxx/xxxxxxx/*.pdf$ Then I realized that I would have to write as many lines as many directories there are in which I want to block pdf files. Let's say I want to block pdf files in all these 3 directories /fileadmin/directory1 /fileadmin/directory1/sub1 /fileadmin/directory1/sub1/pdf Is there a pattern-matching rule I could use to blocks access to pdf files in all subdirectories instead of writing 3x the above line for each subdirectory ? For exemple : Disallow: /fileadmin/directory1*/ Many thanks in advance for any insight you may have.

              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?

              Redirecting HTTP to HTTPS - How long does it take Google to re-index the site?

              hello Moz We know that this year, Moz changed its domain to moz.com from www.seomoz.org
              however, when you type "site:seomoz.org" you still can find old urls indexed on Google (on page 7 and above) We also changed our site from http://www.example.com to https://www.example.com
              And Google is indexing both sites even though we did proper 301 redirection via htaccess. How long would it take Google to refresh the index? We just don't worry about it? Say we redirected our entire site. What is going to happen to those websites that copied and pasted our content? We have already DMCAed their webpages, but making our site https would mean that their website is now more original than our site? Thus, Google assumes that we have copied their site? (Google is very slow on responding to our DMCA complaint) Thank you in advance for your reply.

              Block Domain in robots.txt

              Hi. We had some URLs that were indexed in Google from a www1-subdomain. We have now disabled the URLs (returning a 404 - for other reasons we cannot do a redirect from www1 to www) and blocked via robots.txt. But the amount of indexed pages keeps increasing (for 2 weeks now). Unfortunately, I cannot install Webmaster Tools for this subdomain to tell Google to back off... Any ideas why this could be and whether it's normal? I can send you more domain infos by personal message if you want to have a look at it.

              WordPress - How to stop both http:// and https:// pages being indexed?

              Just published a static page 2 days ago on WordPress site but noticed that Google has indexed both http:// and https:// url's. Usually I only get http:// indexed though. Could anyone please explain why this may have happened and how I can fix? Thanks!

              Singular vs plural in urls

              In keyword research for an ecommerce site, I've found that widget, singular gets a lot more searches than widgets, plural AND is much less competitive. Is it better for SEO purposes to have the URLs (and matching title tags) in the catalog as /brass-widget.html, /steel-widget.html, etc., or /brass-widgets.html, etc.? I'm worried that a) searches for widgets will pass by the singular urls but not vice versa, and b) the singular form will strike visitors as bad grammar. Any advice?
