      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!

                        How much difference does .co.uk vs .com for SEO make?

                        My Website has a .com domain. However I have noticed that for local businesses all of them have a .co.uk (UK business) TLD (check plumbers southampton for example). I have also noticed that on checking my serp rankings, I'm on page 1 if searched on Google.com but page 2 if searched on google.co.uk. Now being UK based I would assume most of my customers will be redirected to google.co.uk so I'm wondering how much of an impact this actually makes? Would it be worth purchasing .co.uk domain and transferring my website to that? Or run them both at the same time and set up 301 direct on my .com to .co.uk? Thanks

                        Moving from a .com to .co.uk

                        I need to migrate a wordpress site from domainname.com to domainname.co.uk. If I just put a 301 on every page on the .com will that cover it? Would it make sense to go and change all the backlinks/profile links to the new .co.uk site or doesn't it matter if you have a 301 redirect on it? Thanks

                        I have been whittling away at the duplicate content on my clients' sites, thanks to SEOmoz's pro report, and have been getting push back from the account manager at register.com (the site was built here and the owner doesn't want to move it).  He says these are the exact same page and he can't access one to redirect to the other.  Any suggestions? The SEOmoz report says there is duplicate content on both these urls: Durango Mountain Biking | Durango Mountain Resort - Cascade Village http://www.cascadevillagehotel.com/index.htm Durango Mountain Biking | Durango Mountain Resort - Cascade Village http://www.cascadevillagehotel.com/ Your help is greatly appreciated!

                        How much to change to avoid duplicate content?

                        Working on a site for a dentist.  They have a long list of services that they want us to flesh out with text.  They provided a bullet list of services, we're trying to get 1 to 2 paragraphs of text for each. Obviously, we're not going to write this off the top of our heads.  We're pulling text from other sources and trying to rework. The question is, how much rephrasing do we have to do to avoid a duplicate content penalty?  Do we make sure there are changes per paragraph, sentence, or phrase? Thanks! Eric

                        Looking to rank a .co.uk domain in the USA

                        Hello Mozzers, One of my clients sites is "domain.co.uk" and they are looking to rank in the USA with the same domain. They are looking to change host (for unrelated reasons) and I think it may be beneficial for them to get hosting in the USA. Essentially the business is moving to the USA but they want to retain their domain name as they cannot get their hands on a domain with their company name in that is .com / .net / .org etc. . . I know that the .co.uk domain will adversely affect click through rates in the states, but there seems to be no way around this if they want their retain the company name as their domain name. Would American based hosting help them rank better for searches from the USA or is the benefit of this negligible? Net66

                        .com or .co.uk in UK index? but the .com has higher domain authority...

                        Hi there i have a .com and a .co.uk for a site that has been around a while. However not much seo has been done on it, i was wonderign do i continue to optimise for the .com or switch to the .co.uk to rank in Google UK index for various search terms. .COM = 40 domain authority .CO.UK - 10 domain authority. Let the debate start 🙂
