          Hi there

          I have a new client who has two websites:

          http://www.bayofislandsteambuilding.co.nz
          http://www.bayofislandsteambuilding.org.nz

          They are the same in every regard apart from the domain extension (.co.nz & .org.nz) which is likely to be causing them issues with Google ranking given the huge amount of duplicate content.

          What is the best practice approach to fixing this? Normally, if I was starting from scratch, I would set one of the extensions as an alias which redirects to the main domain.

          Thanks in advance.

          Laurie

            Two URLs containing the same content will be considered as duplicated content, do the domain level redirection so that every URL should redirect to the home page of the preferred domain.

              Hi - thanks for the response.

              Do I still need to set up 301 redirects for every page or can I do it server-side for the entire domain? And is this approach better than using the rel=”canonical” link element in the http header tags?

              Thanks 🙂

                301 Redirect one to the other. That's it that's all.

                  Hreflang and canonical tag for new country specific website - different base domain

                  I have a little different situation compared to most other questions which asks for hreflang and canonical tags for country specific version of websites. This is an SEO related question and I was hoping to get some insight on your recommendations. We have an existing Australian website - say - ausnight.com.au now we want to launch a UK version of this website - the domain is - uknight.co.uk please note, we are not only changing from .com.au to .co.uk.... but the base domain name as well changed - from ausnight to uknight as you can understand, the audience for both websites is different. Both websites has most pages same with same contents.... the questions I have is - Should we put canonical tag on the new website pages? If we don't put canon tag on new website pages, what is the impact on the SEO ranking of current website? I believe we need to put hreflang tag on both websites to tell google that we have another language version (en-au vs en-gb) of the same page. Is this correct?

                  Sitemaps: Best Practice

                  What should and what shouldn't go in the sitemap? In particular, pages like subscribe to our newsletter/ unsubscribe to our newsletter? Is there really any benefit in highlighting those pages to the SEs? Thanks for any advice/ anecdotes 🙂

                  :Pointing hreflang to a different domain

                  Hi all, Let's say I have two websites: www.mywebsite.com and www.mywebsite.de - they share a lot of content but the main categories and URLs are almost always different. Am I right in saying I can't just set the hreflang tag on every page of www.mywebsite.com to read: rel='alternate' hreflang='de' href='http://mywebsite.de' /> That just won't do anything, right? Am I also right in saying that the only way to use hreflang properly across two domains is to have a customer hreflang tag on every page that has identical content translated into German? So for this page: www.mywebsite.com/page.html my hreflang tag for the german users would be: <link < span="">rel='alternate' hreflang='de' href='http://mywebsite.de/page.html' /></link <> Thanks for your time.

                  Removing duplicate content

                  Due to URL changes and parameters on our ecommerce sites, we have a massive amount of duplicate pages indexed by google, sometimes up to 5 duplicate pages with different URLs. 1. We've instituted canonical tags site wide. 2. We are using the parameters function in Webmaster Tools. 3. We are using 301 redirects on all of the obsolete URLs 4. I have had many of the pages fetched so that Google can see and index the 301s and canonicals. 5. I created HTML sitemaps with the duplicate URLs, and had Google fetch and index the sitemap so that the dupes would get crawled and deindexed. None of these seems to be terribly effective. Google is indexing pages with parameters in spite of the parameter (clicksource) being called out in GWT. Pages with obsolete URLs are indexed in spite of them having 301 redirects. Google also appears to be ignoring many of our canonical tags as well, despite the pages being identical. Any ideas on how to clean up the mess?

                  Membership/subscriber (/customer) only content and SEO best practice

                  Hello Mozzers, I was wondering whether there's any best practice guidance out there re: how to deal with membership/subscriber (existing customer) only content on a website, from an SEO perspective - what is best practice? A few SEOs have told me to make some of the content visible to Google, for SEO purposes, yet I'm really not sure whether this is acceptable / manipulative, and I don't want to upset Google (or users for that matter!) Thanks in advance, Luke

                  How to deal with competition with a similar domain name as my client website?

                  How can I deal with other websites that have a keyword domain name similar to my client website? I get a few domains similar to my client domain name just to avoid the same issue, but there are a few others ranking for the same keywords and I don't want posible customers get confused with a similar domain name. I have social media (Facebook, Twitter, Linked in and etc), but they are not ranking on the first page. This is the situation: www.domain.com that would be my client's domain. And the competition: www.bestdomain.com www.thedomain.com www.domaincomapany.com And a few more. At this time my client is ranking #1 position, but all the others ar 1 or 2 positions bellow.

                  Concerns about duplicate content issues with australian and us version of website

                  My company has an ecommerce website that's been online for about 5 years.  The url is www.betterbraces.com.  We're getting ready to launch an australian version of the website and the url will be www.betterbraces.com.au. The australian website will have the same look as the US website and will contain about 200 of the same products that are featured on the US website.  The only major difference between the two websites is the price that is charged for the products.  The australian website will be hosted on the same server as the US website. To ensure Australians don't purchase from the US site we are going to have a geo redirect in place that sends anyone with a AU ip address to the australian website. I am concerned that the australian website is going to have duplicate content issues.  However, I'm not sure if the fact that the domains are so similar coupled with the redirect will help the search engines understand that these sites are related. I would appreciate any recommendations on how to handle this situation to ensure oue rankings in the search engines aren't penalized. Thanks in advance for your help. Alison French

                  Multiple Domain names pointing at one website

                  Hello, A collegue has asked if we can buy multiple domain names which contain keywords and point them at our website. Is this good practise or will it be seen as spam? Will these domains actually get ranked? I'm sure I'm not the first person to raise this but can't seem to find any questions and answers about this. Thanks Mark
