      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?

                        404 Error Pages being picked up as duplicate content

                        Hi, I recently noticed an increase in duplicate content, but all of the pages are 404 error pages. For instance, Moz site crawl says this page: https://www.allconnect.com/sc-internet/internet.html has 43 duplicates and all the duplicates are also 404 pages (https://www.allconnect.com/Coxstatic.html for instance is a duplicate of this page). Looking for insight on how to fix this issue, do I add an rel=canonical tag to these 60 error pages that points to the original error page? Thanks!

                        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

                        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

                        Block Quotes and Citations for duplicate content

                        I've been reading about the proper use for block quotes and citations lately, and wanted to see if I was interpreting it the right way.  This is what I read: http://www.pitstopmedia.com/sem/blockquote-cite-q-tags-seo So basically my question is, if I wanted to reference Amazon or another stores product reviews, could I use the block quote and citation tags around their content so it doesn't look like duplicate content?  I think it would be great for my visitors, but also to the source as I am giving them credit.  It would also be a good source to link to on my products pages, as I am not competing with the manufacturer for sales.  I could also do this for product information right from the manufacturer. I want to do this for a contact lens site.  I'd like to use Acuvue's reviews from their website, as well as some of their product descriptions.  Of course I have my own user reviews and content for each product on my website, but I think some official copy could do well. Would this be the best method?  Is this how Rottentomatoes.com does it?  On every movie page they have 2-3 sentences from 50 or so reviews, and not much unique content of their own. Cheers, Vinnie

                        UK website ranking higher in Google.com than Google.co.uk

                        Hi, I have a UK website which was formerly ranked 1<sup>st</sup> in Google.co.uk and .com for my keyword phrase and has recently slipped to 6<sup>th</sup> in .co.uk but is higher in position 4 in Google.com. I have conducted a little research and can’t say for certain but I wonder if it is possible that too many of my backlinks are US based and therefore Google thinks my website is also US based. Checked Google WmT and we the geo-targeted to the UK. Our server is also UK based. Does anyone have an opinion on this? Thanks

                        CGI Parameters: should we worry about duplicate content?

                        Hi, My question is directed to CGI Parameters. I was able to dig up a bit of content on this but I want to make sure I understand the concept of CGI parameters and how they can affect indexing pages. Here are two pages: No CGI parameter appended to end of the URL: http://www.nytimes.com/2011/04/13/world/asia/13japan.html CGI parameter appended to the end of the URL: http://www.nytimes.com/2011/04/13/world/asia/13japan.html?pagewanted=2&ref=homepage&src=mv Questions: Can we safely say that CGI parameters = URL parameters that append to the end of a URL? Or are they different? And given that you have rel canonical implemented correctly on your pages, search engines will move ahead and index only the URL that is specified in that tag? Thanks in advance for giving your insights. Look forward to your response. Best regards, Jackson
