          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!

                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.

                  GoogleBot still crawling HTTP/1.1 years after website moved to HTTP/2

                  google http https indexation crawl

                  Whole website moved to https://www. HTTP/2 version 3 years ago. When we review log files, it is clear that - for the home page - GoogleBot continues to only access via HTTP/1.1 protocol Robots file is correct (simply allowing all and referring to https://www. sitemap Sitemap is referencing https://www. pages including homepage Hosting provider has confirmed server is correctly configured to support HTTP/2 and provided evidence of accessing via HTTP/2 working 301 redirects set up for non-secure and non-www versions of website all to https://www. version Not using a CDN or proxy GSC reports home page as correctly indexed (with https://www. version canonicalised) but does still have the non-secure version of website as the referring page in the Discovery section. GSC also reports homepage as being crawled every day or so. Totally understand it can take time to update index, but we are at a complete loss to understand why GoogleBot continues to only go through HTTP/1.1 version not 2 Possibly related issue - and of course what is causing concern - is that new pages of site seem to index and perform well in SERP ... except home page. This never makes it to page 1 (other than for brand name) despite rating multiples higher in terms of content, speed etc than other pages which still get indexed in preference to home page. Any thoughts, further tests, ideas, direction or anything will be much appreciated!

                  DNS vs IIS redirection

                  I'm working on a project where a site has gone through a rebrand and is therefore also moving to a new domain name. Some pages have been merged on the new site so it's not a lift and shift job and so I'm writing up a redirect plan. Their IT dept have asked if we want redirects done by DNS redirect or IIS redirect. Which one will allow us to have redirects on a page level and not a domain level? I think IIS may be the right route but would love your thoughts on this please.

                  Is there any value in having a blank robots.txt file?

                  I've read an audit where the writer recommended creating and uploading a blank robots.txt file, there was no current file in place.  Is there any merit in having a blank robots.txt file? What is the minimum you would include in a basic robots.txt file?

                  We have a client who's main root.com domain is currently penalized by Google, but the subdomain.root.com is appearing very well. We're stumped - any ideas why?

                  Empty Meta Robots Directive - Harmful?

                  Hi, We had a coding update and a side-effect of that was that our directive was emptied, in other words it now reads as: on all of the site. I've since noticed that Google's cache date on all of the pages - at least, the ones I tested - have a Cached date of no later than 17 December '12 - that's the Monday after the directive was removed on mass. So, A, does anyone have solid evidence of an empty directive causing problems? Past experience, Matt Cutts, Fishkin quote, etc. And then B - It seems fairly well correlated but, does my entire site's homogenous Cached date point to this tag removal? Or is it fairly normal to have a particular cache date across a large site (we're a large ecommerce site). Our site: http://www.zando.co.za/ I'm having the directive reinstated as soon as Dev permitting. And then, for extra credit, is there a way with Google's API, or perhaps some other tool, to run an arbitrary list and retrieve Cached dates? I'd want to do this for diagnosis purposes and preferably in a way that OK with Google. I'd avoid CURLing for the cached URL and scraping out that dates with BASH, or any such kind of thing. Cheers,

                  Duplicate content and http and https

                  Within my Moz crawl report, I have a ton of duplicate content caused by identical pages due to identical pages of http and https URL's. For example: http://www.bigcompany.com/accomodations https://www.bigcompany.com/accomodations The strange thing is that 99% of these URL's are not sensitive in nature and do not require any security features.  No credit card information, booking, or carts.  The web developer cannot explain where these extra URL's came from or provide any further information. Advice or suggestions are welcome!  How do I solve this issue? THANKS MOZZERS

                  301 Redirect vs Domain Alias

                  We have hundreds of domains which are either alternate spelling of our primary domain or close keyword names we didn't want our competitor to get before us. The primary domain is running on a dedicated Windows server running IIS6 and set to a static IP. Since it is a static IP and not using host headers any domain pointed to the static IP will immediately show the contents of the site, however the domain will be whatever was typed. Which could be the primary domain or an alias. Two concerns. First, is it possible that Google would penalize us for the alias domains or dilute our primary domain "juice"? Second, we need to properly track traffic from the alias domains. We could make unique content for those performing well and sell or let expire those that are sending no traffic. It's not my goal to use the alias domains to artificially pump up our primary domain. We have them for spelling errors and direct traffic. What is the best practice for handling one or both of these issues?
