      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.

              Why does my old brand name still show up on organic search but as my new brand name and domain?

              Hello mozers! I have quite the conundrum. My client used to have the unfortunate brand name "Meetoo" - which by the way they had before the movement happened! So naturally, they rebranded to the name Vevox in March 2019 to avoid confusion to users. However, when you search for their old brand name "Meetoo" the first organic link that pops up is their domain www.vevox.com. Now, this wouldn't normally be a problem, however it is when any #MeToo news appears in the media and we get a sudden influx or wrong traffic. I've searched the HTML and content for the term "Meetoo" but can only find one trace of this name through a widget. Not enough to hold an organic spot. My only other thinking is that www.vevox.com is redirected from www.meetoo.com. So I'm assuming this is why Vevox appear under the search term "Meetoo". How can I remove the homepage www.vevox.com from appearing for the search term "meetoo"? Can anyone help? AvGGYBc

              Can I use duplicate content in different US cities without hurting SEO?

              So, I have major concerns with this plan. My company has hundreds of facilities located all over the country. Each facility has it's own website. We have a third party company working to build a content strategy for us. What they came up with is to create a bank of content specific to each service line. If/when any facility offers that service, they then upload the content for that service line to that facility website. So in theory, you might have 10-12 websites all in different cities, with the same content for a service. They claim "Google is smart, it knows its content all from the same company, and because it's in different local markets, it will still rank." My contention is that duplicate content is duplicate content, and unless it is "localize" it, Google is going to prioritize one page of it and the rest will get very little exposure in the rankings no matter where you are. I could be wrong, but I want to be sure we aren't shooting ourselves in the foot with this strategy, because it is a major major undertaking and too important to go off in the wrong direction. SEO Experts, your help is genuinely appreciated!

              Same content, different languages. Duplicate content issue? | international SEO

              Hi, If the "content" is the same, but is written in different languages, will Google see the articles as duplicate content?
              If google won't see it as duplicate content. What is the profit of implementing the alternate lang tag?Kind regards,Jeroen

              Same product in different categories and duplicate content issues

              Hi,I have some questions related to duplicate content on e-commerce websites. 1)If a single product goes to multiple categories (eg. A black elegant dress could be listed in two categories like "black dresses" and "elegant dresses") is it considered duplicate content even if the product url is unique? e.g www.website.com/black-dresses/black-elegant-dress duplicated> same content from two different paths www.website.com/elegant-dresses/black-elegant-dress duplicated> same content from two different paths www.website.com/black-elegant-dress unique url > this is the way my products urls look like Does google perceive this as duplicated content? The path to the content is only one, so it shouldn't be seen as duplicated content, though the product is repeated in different categories.This is the most important concern I actually have. It is a small thing but if I set this wrong all website would be affected and thus penalised, so I need to know how I can handle it. 2- I am using wordpress + woocommerce. The website is built with categories and subcategories. When I create a product in the product page backend is it advisable to select  just the lowest subcategory or is it better to select both main category and subcategory in which the product belongs? I usually select the subcategory alone.  Looking forward to your reply and suggestions. thanks

              Different domains for multilingual website

              Hey guys, A site that I'm currently working on as different domains for each website language. So for example: word1word2.com for the english version word3word4.com for the french version word5word6.com for spanish version .... Is it better to move all of the different languages to the same domain and use subfolders for each language /fr/... Please note that the domains being used bring in organic traffic as well as they are EMDs. Thank You.

              Copying my Facebook content to website considered duplicate content?

              I write career advice on Facebook on a daily basis. On my homepage users can see the most recent 4-5 feeds (using FB social media plugin). I am thinking to create a page on my website where visitors can see all my previous FB feeds. Would this be considered duplicate content if I copy paste the info, but if I use a Facebook social media plugin then it is not considered duplicate content? I am working on increasing content on my website and feel incorporating FB feeds would make sense. thank you
