      hi mozzers

      I have a client that has just released a .com version of their .co.uk website. They have basically re-skinned the .co.uk version with some US amends so all the content and title tags are the same. What you do recommend? Canonical tag to the .co.uk version? rewrite titles?

        Just a quick question, the client in question, in their wisdom, decided to put the US website live without telling me and our UK rankings have dropped significantly, do you think the tag will start to fix this?

          It is unlikely because Google normally gives preference to the original for a fairly long period of time. However with Google there are no certainties but they do get this right in almost all cases I have seen.

          The only users you should see decline on your site are non UK visitors as you are telling them with default-x that they should be sent to the .com

          There are many huge companies adopting this process and also thousands of other smaller sites, I think Google has ironed out most of the issues over the last 2 years. You are more likely to see a slower uptake on the new domain than the original than the other way around.

          Hope that helps

            Hi Gary,

            thanks for the help, as a UK website, we primarily want to rank in the UK but we obviously want to rank in the US. By making the .com website (which is brand new) is this likely to affect our UK rankings or should they be unaffected?

            Thanks again,

            Karl

              The actual page you want to look at is https://support.google.com/webmasters/answer/189077

              hreflang is the tag you should implement.

              I have had long chats with John Mueller at Google about this.

              Your setup should be something like this on all pages on both sites.

              Within about 7 days depending on the size of your website the .com should appear in favor of the .co.uk for your US based results. For me it happened within an hour!

              Setting your .com as a default will be better than setting your co.uk.  The co.uk is already a region specific TLD and will not rank well generally in other search engines even if set in the hreflang to do differently.

              This will let Google decide where to send traffic too based on their algo/data.

              If you use a canonical tag you will be suggesting/pushing US users to the original content instead of the US site.

                Ok, thanks for the help. I'll have a look into it and see what it says. The .com website is up now and they are hell bent on it staying! I did recommend having a /US but they preferred the .com!

                Anyway thanks for the advice!

                  Hiya,

                  The alternative tag is a good start but you may want to do some more reading I'll put some links below. It's easier to try to make unique content or have a structure like www.example.com/us which may be an easier short term until you've got enough content for a .com site.

                  http://webmasters.stackexchange.com/questions/19032/can-duplicate-content-on-a-com-and-a-co-uk-site-impact-google-ranking

                  http://moz.com/community/q/duplicate-content-on-multinational-sites

                  https://support.google.com/webmasters/answer/182192#3

                  I always find it nicer to formulate your own answers and learn a bit along the way so I help the above helps you do that.

                    Thanks Chris,

                    So would you implement the rel=alternative href=x tag then?

                        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!

                        Duplicate Content on a Page Due to Responsive Version

                        What are the implications if a web designer codes the content of the site twice into the page in order to make the site responsive? I can't add the url I'm afraid but the H1 and the content appear twice in the code in order to produce both a responsive version and a desktop version. This is a Wordpress site. Is Google clever enough to distinguish between the 2 versions and treat them individually? Or will Google really think that the content has been repeated on the same page?

                        Duplicate Content Issue WWW and Non WWW

                        One of my sites got hit with duplicate content a while ago because Google seemed to be considering hhtp, https, www, and non ww versions of the site all different sites. We thought we fixed it, but for some reason https://www and just https:// are giving us duplicate content again. I can't seem to figure out why it keeps doing this. The url is https://bandsonabudget.com if any of you want to see if you can figure out why I am still having this issue.

                        Headers & Footers Count As Duplicate Content

                        I've read a lot of information about duplicate content across web pages and was interested in finding out about how that affected the header and footer of a website. A lot of my pages have a good amount of content, but there are some shorter articles on my website.  Since my website has a header, footer, and sidebar that are static, could that hurt my ranking? My only concern is that sometimes there's more content in the header/footer/sidebar than the article itself since I have an extensive amount of navigation. Is there a way to define to Google what the header and footer is so that they don't consider it to be duplicate content?

                        Duplicate Content

                        We have a ton of duplicate content/title errors on our reports, many of them showing errors of: http://www.mysite.com/(page title) and http://mysite.com/(page title) Our site has been set up so that mysite.com 301 redirects to www.mysite.com (we did this a couple years ago). Is it possible that I set up my campaign the wrong way in SEOMoz? I'm thinking it must be a user error when I set up the campaign since we already have the 301 Redirect. Any advice is appreciated!

                        Duplicate Content and URL Capitalization

                        I have multiple URLs that SEOMoz is reporting as duplicate content.  The reason is that there are characters in the URL that may, or may not, be capitalized depending on user input. A couple examples are: www.househitz.com/Pennsylvania/Houses-for-sale www.househitz.com/Pennsylvania/houses-for-sale www.househitz.com/Pennsylvania/Houses-for-rent www.househitz.com/Pennsylvania/houses-for-rent There are currently thousands of instances of this on the site. Is this something I should spend effort to try and resolve (may not be minor effort), or should I just ignore it and move on?

                        Duplicate content problem from an index.php file

                        Hi One of my sites is flagging a duplicate content problem which is affecting the search rankings. The duplicate problem is caused by http://www.mydomain.com/index.php which has a page rank of 26 How can I sort the duplicate content problem, as the main page should just be http://www.mydomain.com which has a page rank of 42 and is the stronger page with stronger links etc Many Thanks

                        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
