      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

        Hard to tell without knowing the site, but it's possible there are external links to "https" versions of the pages. At this point, Google is going to increase the pressure to secure sites, and later this year Chrome will start warning users about all non-secure pages, so it may be worth making the move.

          I'm reading this response and this is happening on my site as well.  How did this happen in the first place?  I have duplicate content because of https and http copies of all my web pages.  If I type https://www.mywebsite.com I can't get to my site.  Could this be coming from my hosting company?  I've set up my site to simply be http://www.mywebsite.com.  I'm a little worried to change my robots.txt and I would love to know how this happened in the first place.

            If Google detects both http: and https: versions, they've started to automatically pick the https: version, but that's not consistent yet. In general, I think it's still important to set strong canonicalization signals. Google still separates your http: and https: sites in Google Search Console, too, so even they haven't quite made up their minds.

            In general, Google is pushing sites toward https:, but that's a somewhat complex decision that depends on more than just SEO. If you're using https: and the https: URLs are indexed, then you should treat those as canonical and suppress the http: URLs, in most cases.

              Hate to respond to a 3 year old thread. But does this solution needs to be updated?

              Is there any change in response now, as Google is favoring https for most pages. Does google still consider http and https as two different sites? If so which one should be suppressed - http or https?

                Hi,

                I'm still having problems with redirecting. I only have 1 duplicate page with https and http, that I want to redirect but it's the homepage.

                i want to redirect: https://www.domain.com to http://www.domain.com

                But keep the rest of the pages the same (half http and the other half https).

                How do i do this?

                  Anytime Rand!  I only have two simple rules:

                  1.  Talking business on ski days is not allowed

                  2.  Entry into Vermont requires a pound of Seattle's best french roast coffee.  In return, you  receive some fantastic Vermont maple syrup.

                  Simple rules to live by LOL

                  Thanks again for all of your help...

                  Peter

                      Sorry, I was using Big Company as an example and just being generic.

                      The real URL if interested is www.hawkresort.com

                        I would personally like to thank everyone that responded with an answer.  Man O Man, the best part of belonging to SEOMOZ is the community forum.  It's incredibly valuable, being able to ask a question and reach out to such talent as all of you.

                        If anyone ever gets up to Killington or Okemo skiing, the beer is on me!  I live right between both ski areas, about 8 miles to either mountain..

                        Thanks again.

                          I think Harald and James covered the bases here, but a couple of comments on Harald's reply:

                          (1) Definitely check this. A common cause of indexed https: pages is that a secure section of your site is being crawled (like a shopping cart), and you're using relative navigation links (like ) - when a crawler or visitor hits the nav link from a secure page, the relative link grabs the https: In most cases, you may want to NOINDEX secure pages. Shopping carts and checkout pages have no business in the search index, IMO.

                          [(2)-(5) I believe this does work, but it's very tricky, so please be careful. If anyone has linked to the https: pages, you'll lose the link-juice this way (you'll just cut those pages off). I honestly don't think it's a good choice for most sites.

                          (8) I actually believe the 301-redirect is simpler in most cases.

                          As James said, sitewide canonical tags (or on the affect pages, if they're isolated) will also work.](/contact.php)

                            Hi Serge, I came to know about the "robots_ssl.txt" from the website  http://www.seoworkers.com/seo-articles-tutorials/robots-and-https.html

                              I would check your server for a https folder.

                              add a robots.txt file in the root of the https folder:

                              User-agent: *
                              Disallow:/

                              My guess is that the spider is following a link somewhere within your site that links to a https:// url.  The spider is than re-indexing the entire site using https://

                              My 2 cents for what its worth.

                                  Hello Hawkvt1, Fisrt of all I want to tell you that  the protocols (http/https) are different, they are considered two separate sites, so there’s a good chance to get penalized for duplicate content. If the search engine discovers two identical pages, generally it would take the page it saw first and ignore the other pages.The solutions are described below:

                                  S__olutions:

                                  1. Be smart about the site structure:  to keep the engines from crawling and indexing HTTPS pages, structure the website so that HTTPs are only accessible through a form submission (log-in, sign-up, or payment pages). The common mistake is making these pages available via a standard link (happens when you are either ignorant or  not aware that the secure version of the site is being crawled and indexed).
                                  2. Use Robots.txt file to control which pages will be crawled and indexed
                                  3. Use.htaccess file. Here’s how to do this:
                                  4. Create a file names robots_ssl.txt in your root.
                                  5. Add the following code to your .htaccessRewriteCond %{SERVER_PORT} 443 [NC]RewriteRule ^robots.txt$ robots_ssl.txt [L]
                                  6. Remove yourdomain.com:443 from the webmaster tools if the pages have already been crawled
                                  7. For dynamic pages like php, try< ?phpif ($_SERVER["SERVER_PORT"] == 443){echo “< meta name=” robots ” content=” noindex,nofollow ” > “;}?>
                                  8. Dramatic solution (may not always be possible): 301 redirect the HTTPS pages to the HTTP pages – with hopes that the link juice will transfer over.

                                  For more information please refer to this link :

                                    You could implement the canonical tag onto the HTTP version of the website.

                                    Another problem when having a quick look at this website is that all your title tags are the same with the brand term at the front, this is not advisable at all you want to put the brand term at the end of the title and your generic terms first.

                                    I would look at getting an SEO audit done to fix the issues with the website.

                                      Hi there and thank you in advance for your help! I'm seeking guidance on how to structure a resources directory (white papers, webinars, etc.) while avoiding duplicate content penalties. If you go to /resources on our site, there is filter function. If you filter for webinars, the URL becomes /resources/?type=webinar We didn't want that dynamic URL to be the primary URL for webinars, so we created a new page with the URL /resources/webinar that lists all of our webinars and includes a featured webinar up top. However, the same webinar titles now appear on the /resources page and the /resources/webinar page. Will that cause duplicate content issues? P.S. Not sure if it matters, but we also changed the URLs for the individual resource pages to include the resource type. For example, one of our webinar URLs is /resources/webinar/forecasting-your-revenue Thank you!

                                      Duplicate Content Issues with Pagination

                                      Hi Moz Community, We're an eCommerce site so we have a lot of pagination issues but we were able to fix them using the rel=next and rel=prev tags. However, our pages have an option to view 60 items or 180 items at a time. This is now causing duplicate content problems when for example page 2 of the 180 item view is the same as page 4 of the 60 item view. (URL examples below) Wondering if we should just add a canonical tag going to the the main view all page to every page in the paginated series to get ride of this issue. https://www.example.com/gifts/for-the-couple?view=all&n=180&p=2 https://www.example.com/gifts/for-the-couple?view=all&n=60&p=4 Thoughts, ideas or suggestions are welcome. Thanks

                                      Duplicate content and 404 errors

                                      I apologize in advance, but I am an SEO novice and my understanding of code is very limited. Moz has issued a lot (several hundred) of duplicate content and 404 error flags on the ecommerce site my company takes care of. For the duplicate content, some of the pages it says are duplicates don't even seem similar to me. additionally, a lot of them are static pages we embed images of size charts that we use as popups on item pages. it says these issues are high priority but how bad is this? Is this just an issue because if a page has similar content the engine spider won't know which one to index? also, what is the best way to handle these urls bringing back 404 errors? I should probably have a developer look at these issues but I wanted to ask the extremely knowledgeable Moz community before I do 🙂

                                      Which Sitemap to keep - Http or https (or both)

                                      Hi, Just finished upgrading my site to the ssl version (like so many other webmasters now that it may be a ranking factor). FIxed all links, CDN links are now secure, etc and 301 Redirected all pages from http to https. Changed property in Google Analytics from http to https and added https version in Webmaster Tools. So far, so good. Now the question is should I add the https version of the sitemap in the new HTTPS site in webmasters or retain the existing http one? Ideally switching over completely to https version by adding a new sitemap would make more sense as the http version of the sitemap would anyways now be re-directed to HTTPS. But the last thing i can is to get penalized for duplicate content. Could you please suggest as I am still a rookie in this department. If I should add the https sitemap version in the new site, should i delete the old http one or no harm retaining it.

                                      Is duplicate content ok if its on LinkedIn?

                                      Hey everyone, I am doing a duplicate content check using copyscape, and realized we have used a ton of the same content on LinkedIn as our website. Should we change the LinkedIn company page to be original? Or does it matter? Thank you!

                                      Localized domains and duplicate content

                                      Hey guys, In my company we are launching a new website and there's an issue it's been bothering me for a while. I'm sure you guys can help me out. I already have a website, let's say ABC.com I'm preparing a localized version of that website for the uk so we'll launch ABC.co.uk Basically the websites are going to be exactly the same with the difference of the homepage. They have a slightly different proposition. Using GeoIP I will redirect the UK traffic to ABC.co.uk and the rest of the traffic will still visit .com website. May google penalize this? The site itself it will be almost the same but the homepage. This may count as duplicate content even if I'm geo-targeting different regions so they will never overlap. Thanks in advance for you advice

                                      Are recipes excluded from duplicate content?

                                      Does anyone know how recipes are treated by search engines? For example, I know press releases are expected to have lots of duplicates out there so they aren't penalized. Does anyone know if recipes are treated the same way. For example, if you Google "three cheese beef pasta shells" you get the first two results with identical content.
