      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.

              Robots.txt allows wp-admin/admin-ajax.php

              Hello, Mozzers!
              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.
              -AK:

              Is sitemap required on my robots.txt?

              Hi, I know that linking your sitemap from your robots.txt file is a good practice. Ok, but... may I just send my sitemap to search console and forget about adding ti to my robots.txt? That's my situation: 1 multilang platform which means... ... 2 set of pages. One for each lang, of course But my CMS (magento) only allows me to have 1 robots.txt file So, again: may I have a robots.txt file woth no sitemap AND not suffering any potential SEO loss? Thanks in advance, Juan Vicente Mañanas Abad

              Title Tag vs. H1 / H2

              OK, Title tag, no problem, it's the SEO juice, appears on SERP, etc.  Got it. But I'm reading up on H1 and getting conflicting bits of information ... Only use H1 once? H1 is crucial for SERP Use H1s for subheads Google almost never looks past H2 for relevance So say I've got a blog post with three sections ... do I use H1 three times (or does Google think you're playing them ...) Or do I create a "big" H1 subhead and then use H2s? Or just use all H2s because H1s are scary?  🙂 I frequently use subheads, it would seem weird to me to have one a font size bigger than another, but of course I can adjust that in settings ... Thoughts? Lisa

              Flat vs Hierarchical URL Structure

              Hi, We are redoing our site structure and I was wondering what are the benefits of having a flat url structure. For example store.com/product instead of doing store.com/category/product. I noticed sites doing it both ways, even moz.com has both structures ex: moz.com/learn/seo and when you clck on something it brings you to moz.com/seo-expert-quiz (even though following the previous logic it should be moz.com/learn/seo/seo-expert-quiz) Please advise, Thanks!

              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.

              Will an XML sitemap override a robots.txt

              I have a client that has a robots.txt file that is blocking an entire subdomain, entirely by accident. Their original solution, not realizing the robots.txt error, was to submit an xml sitemap to get their pages indexed. I did not think this tactic would work, as the robots.txt would take precedent over the xmls sitemap. But it worked... I have no explanation as to how or why. Does anyone have an answer to this? or any experience with a website that has had a clear Disallow: / for months , that somehow has pages in the index?

              Oh no googlebot can not access my robots.txt file

              I just receive a n error message from google webmaster Wonder it was something to do with Yoast plugin. Could somebody help me with troubleshooting this? Here's original message Over the last 24 hours, Googlebot encountered 189 errors while attempting to access your robots.txt. To ensure that we didn't crawl any pages listed in that file, we postponed our crawl. Your site's overall robots.txt error rate is 100.0%. Recommended action If the site error rate is 100%: Using a web browser, attempt to access http://www.soobumimphotography.com//robots.txt. If you are able to access it from your browser, then your site may be configured to deny access to googlebot. Check the configuration of your firewall and site to ensure that you are not denying access to googlebot. If your robots.txt is a static page, verify that your web service has proper permissions to access the file. If your robots.txt is dynamically generated, verify that the scripts that generate the robots.txt are properly configured and have permission to run. Check the logs for your website to see if your scripts are failing, and if so attempt to diagnose the cause of the failure. If the site error rate is less than 100%: Using Webmaster Tools, find a day with a high error rate and examine the logs for your web server for that day. Look for errors accessing robots.txt in the logs for that day and fix the causes of those errors. The most likely explanation is that your site is overloaded. Contact your hosting provider and discuss reconfiguring your web server or adding more resources to your website. After you think you've fixed the problem, use Fetch as Google to fetch http://www.soobumimphotography.com//robots.txt to verify that Googlebot can properly access your site.

              Ror.xml vs sitemap.xml

              Hey Mozzers, So I've been reading somethings lately and some are saying that the top search engines do not use ror.xml sitemap but focus just on the sitemap.xml.  Is that true? Do you use ror? if so, for what purpose, products, "special articles", other uses? Can sitemap be sufficient for all of those? Thank you, Vadim
