      When we pull up Google Search Console, in the Index Coverage section, under the category of Excluded, there is a sub-category called ‘Duplicate page without canonical tag’.  The majority of the 665 pages in that section are from a test environment.

      If we were to include in the robots.txt file, a wildcard to cover every URL that started with the particular root URL ("www.domain.com/host/"), could we eliminate the majority of these errors?

      That solution is not one of the 5 or 6 recommended solutions that the Google Search Console Help section text suggests.  It seems like a simple effective solution.  Are we missing something?

        No index & test Indexing Before You Launch

        The domains are intended for development use and cannot be used for production. A custom or CMS-standard will only work robots.txt on Live environments with a custom domain. Adding sub-domains (i.e., dev.example.com , ``test.example.com) for DEV or TEST will remove the header only, X-Robots-Tag: noindex but still, serve the domain. robots.txt 

        To support pre-launch SEO testing, we allow the following bots access to platform domains:

        • Site Auditor by Raven
        • SEMrush
        • RogerBot by Moz
        • Dotbot by Moz

        If you’re testing links or SEO with other tools, you may request the addition of the tool to our robots.txt

        Pantheon's documentation on robots.txt: http://pantheon.io/docs/articles/sites/code/bots-and-indexing/User-agent: * Disallow: / User-agent: RavenCrawler User-agent: rogerbot User-agent: dotbot User-agent: SemrushBot User-agent: SemrushBot-SA Allow: /

          The simplest solution would be to mark every page in your test environment "noindex". This is normally standard operating procedure anyway because most people don't want customers stumbling across the wrong URL in search by mistake and seeing a buggy page that isn't supposed to be "live" for customers.

          Updating your robots.txt file would tell Google not to crawl the page, but if they've already crawled it and added it to their index it just means that they will retain the last crawled version of the page and will not crawl it in the future. You have to direct Google to "noindex" the pages. It will take some time as Google refreshes the crawl of each page, but eventually you'll see those errors drop off as Google removes those pages from their index. If I were consulting a client I would tell them to make the change and check back in two or three months.

          Hope this helps!

            The new version of search console will show all the pages available on your site. even the no-index pages, why? I don't know, the truth is even when you set up those pages as no-follow and no-index it will keeping show you the same error. That does not mean that there is something wrong with your site. I would not worry in your case.

              Page Indexing without content

              indexing seo

              Hello. I have a problem of page indexing without content. I have website in 3 different languages and 2 of the pages are indexing just fine, but one language page (the most important one) is indexing without content. When searching using site: page comes up, but when searching unique keywords for which I should rank 100% nothing comes up. This page was indexing just fine and the problem arose couple of days ago after google update finished. Looking further, the problem is language related and every page in the given language that is newly indexed has this problem, while pages that were last crawled around one week ago are just fine. Has anyone ran into this type of problem?

              Dynamic Canonical Tag for Search Results Filtering Page

              canonical indexation search page categorization search results crawl

              Hi everyone, I run a website in the travel industry where most users land on a location page (e.g. domain.com/product/location, before performing a search by selecting dates and times. This then takes them to a pre filtered dynamic search results page with options for their selected location on a separate URL (e.g. /book/results). The /book/results page can only be accessed on our website by performing a search, and URL's with search parameters from this page have never been indexed in the past. We work with some large partners who use our booking engine who have recently started linking to these pre filtered search results pages. This is not being done on a large scale and at present we only have a couple of hundred of these search results pages indexed. I could easily add a noindex or self-referencing canonical tag to the /book/results page to remove them, however it’s been suggested that adding a dynamic canonical tag to our pre filtered results pages pointing to the location page (based on the location information in the query string) could be beneficial for the SEO of our location pages. This makes sense as the partner websites that link to our /book/results page are very high authority and any way that this could be passed to our location pages (which are our most important in terms of rankings) sounds good, however I have a couple of concerns. • Is using a dynamic canonical tag in this way considered spammy / manipulative? • Whilst all the content that appears on the pre filtered /book/results page is present on the static location page where the search initiates and which the canonical tag would point to, it is presented differently and there is a lot more content on the static location page that isn’t present on the /book/results page. Is this likely to see the canonical tag being ignored / link equity not being passed as hoped, and are there greater risks to this that I should be worried about? I can’t find many examples of other sites where this has been implemented but the closest would probably be booking.com. https://www.booking.com/searchresults.it.html?label=gen173nr-1FCAEoggI46AdIM1gEaFCIAQGYARS4ARfIAQzYAQHoAQH4AQuIAgGoAgO4ArajrpcGwAIB0gIkYmUxYjNlZWMtYWQzMi00NWJmLTk5NTItNzY1MzljZTVhOTk02AIG4AIB&sid=d4030ebf4f04bb7ddcb2b04d1bade521&dest_id=-2601889&dest_type=city& Canonical points to https://www.booking.com/city/gb/london.it.html In our scenario however there is a greater difference between the content on both pages (and booking.com have a load of search results pages indexed which is not what we’re looking for) Would be great to get any feedback on this before I rule it out. Thanks!

              Duplicate content, although page has "noindex"

              duplicate content

              Hello, I had an issue with some pages being listed as duplicate content in my weekly Moz report. I've since discussed it with my web dev team and we decided to stop the pages from being crawled. The web dev team added this coding to the pages <meta name='robots' content='max-image-preview:large, noindex dofollow' />, but the Moz report is still reporting the pages as duplicate content. Note from the developer "So as far as I can see we've added robots to prevent the issue but maybe there is some subtle change that's needed here. You could check in Google Search Console to see how its seeing this content or you could ask Moz why they are still reporting this and see if we've missed something?" Any help much appreciated!

              "Noindex, follow" for thin pages?

              Hey there Mozzers, I have a question regarding Thin pages. Unfortunately, we have Thin pages, almost empty to be honest. I have the idea to ask the dev team to do "noindex, follow"  on these pages. What do you think? Has someone faced this situation before? Will appreciate your input!

              Rel=Canonical For Landing Pages

              We have PPC landing pages that are also ranking in organic search. We've decided to create new landing pages that have been improved to rank better in natural search. The PPC team however wants to use their original landing pages so we are unable to 301 these pages to the new pages being created. We need to block the old PPC pages from search. Any idea if we can use rel=canonical? The difference between old PPC page and new landing page is much more content to support keyword targeting and provide value to users. Google says it's OK to use rel=canonical if pages are similar but not sure if this applies to us. The old PPC pages have 1 paragraph of content followed by featured products for sale. The new pages have 4-5 paragraphs of content and many more products for sale. The other option would be to add meta noindex to the old PPC landing pages. Curious as to what you guys think. Thanks.

              How Does Google's "index" find the location of pages in the "page directory" to return?

              This is my understanding of how Google's search works, and I am unsure about one thing in specific: Google continuously crawls websites and stores each page it finds (let's call it "page directory") Google's "page directory" is a cache so it isn't the "live" version of the page Google has separate storage called "the index" which contains all the keywords searched.  These keywords in "the index" point to the pages in the "page directory" that contain the same keywords. When someone searches a keyword, that keyword is accessed in the "index" and returns all relevant pages in the "page directory" These returned pages are given ranks based on the algorithm The one part I'm unsure of is how Google's "index" knows the location of relevant pages in the "page directory".  The keyword entries in the "index" point to the "page directory" somehow. I'm thinking each page has a url in the "page directory", and the entries in the "index" contain these urls.   Since Google's "page directory" is a cache, would the urls be the same as the live website (and would the keywords in the "index" point to these urls)? For example if webpage is found at wwww.website.com/page1, would the "page directory" store this page under that url in Google's cache? The reason I want to discuss this is to know the effects of changing a pages url by understanding how the search process works better.

              Hreflang on non-canonical pages

              Hi! I've been trying to figure out what is the best way to solve this dilemma with duplicate content and multiple languages across domains. 1 product info page 2 same product but GREEN
              3 same product but RED
              4 same product but YELLOW **Question: ** Since pages 2,3,4 just varies slightly I use the canonical tag to indicate they are duplicates of page 1. Now I also want to indicate there are other language versions with the_ rel="alternate" hreflang="x" _element. Should I place the _rel="alternate" hreflang="x" _on the canonical page only pointing to the canonical page with "x" language. Should I place the _rel="alternate" hreflang="x" _on all pages pointing to the canonical page with the "x" language? Should I place the _rel="alternate" hreflang="x"  _on all pages and then point it to the translated page (even if it is not a canonical page) ? /Lars
