      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.

              Does Google read dynamic canonical tags?

              Does Google recognize rel=canonical tag if loaded dynamically via javascript? Here's what we're using to load: <script> //Inject canonical link into page head if (window.location.href.indexOf("/subdirname1") != -1) { canonicalLink = window.location.href.replace("/kapiolani", ""); } if (window.location.href.indexOf("/subdirname2") != -1) { canonicalLink = window.location.href.replace("/straub", ""); } if (window.location.href.indexOf("/subdirname3") != -1) { canonicalLink = window.location.href.replace("/pali-momi", ""); } if (window.location.href.indexOf("/subdirname4") != -1) { canonicalLink = window.location.href.replace("/wilcox", ""); } if (canonicalLink != window.location.href) { var link = document.createElement('link'); link.rel = 'canonical'; link.href = canonicalLink; document.head.appendChild(link); } script>

We have a link that containing by https://finance.rabbit.co.th/car-insurance?showForm=1&brand_id=9&model_id=18&car_submodel_id=30&ci_source_id=rabbit.co.th&car_year=2014 and setting canonical to this url - https://finance.rabbit.co.th/car-insurance within 5,000 items. But in this case I have an warning by site audit tools as Duplicate Page Title (Canonical), So is that possible to drop our ranking. What should we do, setting No-Index, No-Follow for all URL that begin with ? or keep them like that.

              What is the difference between "Referring Pages" and "Total Backlinks" [on Ahrefs]?

              I always thought they were essentially the same thing myself but appears there may be a difference? Any one care to help me out? Cheers!

              "nofollow pages" or "duplicate content"?

              We have a huge site with lots of geographical-pages in this structure: domain.com/country/resort/hotel domain.com/country/resort/hotel/facts domain.com/country/resort/hotel/images domain.com/country/resort/hotel/excursions domain.com/country/resort/hotel/maps domain.com/country/resort/hotel/car-rental Problem is that the text on ie. /excursions is often exactly the same on .../alcudia/hotel-sea-club/excursion and .../alcudia/hotel-beach-club/excursion The two hotels offer the same excursions, and the intro text on the pages are the exact same throughout the entire site. This is also a problem on the /images and /car-rental pages. I think in most cases the only difference on these pages is the Title, description and H1. These pages do not attract a lot of visits through search-engines. But to avoid them being flagged as duplicate content (we have more than 4000 of these pages - /excursions, /maps, /car-rental, /images), do i add a nofollow-tag to these, do i block them in robots.txt or should i just leave them and live with them being flagged as duplicate content? Im waiting for our web-team to add a function to insert a geographical-name in the text, so i could add ie #HOTELNAME# in the text and thereby avoiding the duplicate text. Right now we have intros like: When you visit the hotel ... instead of: When you visit Alcudia Sea Club But untill the web-team has fixed these GEO-tags, what should i do? What would you do and why?

              Does the rel="bookmark" tag have any SEO impication?

              I'm assuming the rel="bookmark" tag doesn't have any SEO implications but I just wanted to make sure it wasn't viewed like a nofollow by search engines.

              Hi SEOMoz! Can I have the rel=canonical tag on a URL page that has a 302 redirection? Does this harm the search engine friendliness of a content page / website? Thanks! Steve
