      Hello all,

      I look after (in house) 3 domains for one niche travel business across three TLDs: .com .com.au and co.uk and a fourth domain on a co.nz TLD which was recently removed from Googles index.

      Symptoms:

      For the past 12 months we have been experiencing canibalisation in the SERPs (namely .com.au being rendered in .com) and Panda related ranking devaluations between our .com site and com.au site.

      Around 12 months ago the .com TLD was hit hard (80% drop in target KWs) by Panda (probably) and we began to action the below changes. Around 6 weeks ago our .com TLD saw big overnight increases in rankings (to date a 70% averaged increase). However, almost to the same percentage we saw in the .com TLD we suffered significant  drops in our .com.au rankings. Basically Google seemed to switch its attention from .com TLD to the .com.au TLD.

      Note: Each TLD is over 6 years old, we've never proactively gone after links (Penguin) and have always aimed for quality in an often spammy industry.

      **Have done: **

      • Adding HREF LANG markup to all pages on all domain
      • Each TLD uses local vernacular e.g for the .com site is American
      • Each TLD has pricing in the regional currency
      • Each TLD has details of the respective local offices, the copy references the lacation, we have significant press coverage in each country like The Guardian for our .co.uk site and Sydney Morning Herlad for our Australia site
      • Targeting each site to its respective market in WMT
      • Each TLDs core-pages (within 3 clicks of the primary nav) are 100% unique
      • We're continuing to re-write and publish unique content to each TLD on a weekly basis
      • As the .co.nz site drove such little traffic re-wrting we added no-idex and the TLD has almost compelte dissapread (16% of pages remain) from the SERPs.
      • XML sitemaps
      • Google + profile for each TLD

      **Have not done: **

      • Hosted each TLD on a local server
      • Around 600 pages per TLD are duplicated across all TLDs (roughly 50% of all content). These are way down the IA but still duplicated.
      • Images/video sources from local servers
      • Added address and contact details using SCHEMA markup

      Any help, advice or just validation on this subject would be appreciated!

      Kian

        Hey Simon,

        The Australia is lang="en-au"

        The UK is lang="en-gb"

        The US is lang="en-us"

        We've tried to keep these as tight per country as possible so opted not to use the straight 'en'.

        In analytics, there has been some reduction is language referrals, mainly "en-gb" falling from the number one language type for the US site, which is a positive. Interstingly enough, once we removed the .co.nz fro mthe Index the .com site remove in to dominate the SERPs for brand and some core-KW searches in Google.co.nz.

        Its a little unfortunate as Panda, from my understanding, is keen to spare ccTLDs from any harsh devaluations, but we'll hopefully be able to hit whatever threshold for % of unique content in the near future.

        We have review functionality planned for each TLD which should help add value to existing duplicate content. Once this is up and I have some more robust data I'll pull a post together for YouMoz.

        Thanks for the feedback!

        Kian

          Wow, that's a pretty comprehensive list of actions you've compiled there and you seem to have covered pretty much all the bases. I almost think your post should be promoted on Youmoz as a great step of actions for targeting regional websites.

          My experience of hreflang is that it is not perfect in that you occasionally get the wrong versions of pages served in SERPs. I wonder do you specify the .com as 'en' in the hreflang mark up in order that it is the generic English language version as opposed to being country specific?

            Country Code Top Level Domains & Duplicate Content

            Hi looking to launch in a new market, currently we have a .com.au domain which is geo-targeted to Australia. We want to launch in New Zealand which is ends with .co.nz If i duplicate the Australian based site completely on the new .co.nz domain name, would i face duplicate content issues from a SEO standpoint?
            Even though it's on a completely separate country code. Or is it still advised tosetup hreflang tag across both of the domains? Cheers.

            Directory with Duplicate content? what to do?

            Moz keeps finding loads of pages with duplicate content on my website. The problem is its a directory page to different locations. E.g if we were a clothes shop we would be listing our locations: www.sitename.com/locations/london www.sitename.com/locations/rome www.sitename.com/locations/germany The content on these pages is all the same, except for an embedded google map that shows the location of the place. The problem is that google thinks all these pages are duplicated content. Should i set a canonical link on every single page saying that www.sitename.com/locations/london is the main page? I don't know if i can use canonical links because the page content isn't identical because of the embedded map. Help would be appreciated. Thanks.

            Does collapsing content impact Google SEO signals?

            Recently I have been promoting custom long form content development for major brand clients.  For UX reasons we collapse the content so only 2-3 sentences of the first paragraph are visible.  However there is a "read more" link that expands the entire content piece.
            I have believed that the searchbots would have no problem crawling, indexing and applying a positive SEO signal for this content.  However I'm starting to wonder.  Is there any evidence that the Google search algorithm could possible discount or even ignore collapsed content?

            Duplicate content due to parked domains

            I have a main ecommerce website with unique content and decent back links. I had few domains parked on the main website as well specific product pages. These domains had some type in traffic. Some where exact product names.  So main main website www.maindomain.com had domain1.com , domain2.com parked on it. Also had domian3.com parked on www.maindomain.com/product1. This caused lot of duplicate content issues. 12 months back, all the parked domains were changed to 301 redirects. I also added all the domains to google webmaster tools. Then removed main directory from google index. Now realize few of the additional domains are indexed and causing duplicate content. My question is what other steps can I take to avoid the duplicate content for my my website 1. Provide change of address in Google search console. Is there any downside in providing change of address pointing to a website? Also domains pointing to a specific url , cannot provide change of address 2. Provide a remove page from google index request in Google search console. It is temporary and last 6 months. Even if the pages are removed from Google index, would google still see them duplicates? 3. Ask google to fetch each url under other domains and submit to google index. This would hopefully remove the urls under domain1.com and doamin2.com eventually due to 301 redirects. 4. Add canonical urls for all pages in the main site. so google will eventually remove content from doman1 and domain2.com due to canonical links. This wil take time for google to update their index 5. Point these domains elsewhere to remove duplicate contents eventually. But it will take time for google to update their index with new non duplicate content. Which of these options are best best to my issue and which ones are potentially dangerous? I would rather not to point these domains elsewhere. Any feedback would be greatly appreciated.

            Woocommerce SEO & Duplicate content?

            Hi Moz fellows, I'm new to Woocommerce and couldn't find help on Google about certain SEO-related things. All my past projects were simple 5 pages websites + a blog, so I would just no-index categories, tags and archives to eliminate duplicate content errors. But with Woocommerce Product categories and tags, I've noticed that many e-Commerce websites with a high domain authority actually rank for certain keywords just by having their category/tags indexed. For example keyword 'hippie clothes' = etsy.com/category/hippie-clothes (fictional example) The problem is that if I have 100 products and 10 categories & tags on my site it creates THOUSANDS of duplicate content errors, but If I 'non index' categories and tags they will never rank well once my domain authority rises... Anyone has experience/comments about this? I use SEO by Yoast plugin. Your help is greatly appreciated! Thank you in advance. -Marc

            SEO Impact of High Volume Vertical and Horizontal Internal Linking

            Hello Everyone - I maintain a site with over a million distinct pages of content. Each piece of content can be thought of like a node in graph database or an entity. While there is a bit of natural hierarchy, every single entity can be related to one or more other entities. The conceptual structure of the entities like so: Agency - A top level business unit ( ~100 pages/urls) Office - A lower level business unit, part of an Agency ( ~5,000 pages/urls) Person - Someone who works in one or more Offices ( ~80,000 pages/urls) Project - A thing one or more People is managing ( ~750,000 pages/urls) Vendor - A company that is working on one or more Projects ( ~250,000 pages/urls) Category - A descriptive entity, defining one or more Projects ( ~1,000 pages/urls) Each of these six entities has a unique (url) and content. For each page/url, there are internal links to each of the related entity pages. For example, if a user is looking at a Project page/url, there will be an internal link to one or more Agencies, Offices, People, Vendors, and Categories. Also, a Project will have links to similar Projects. This same theory holds true for all other entities as well. People pages link to their related Agencies, Offices, Projects, Vendors, etc, etc. If you start to do the math, there are tons of internal links leading to pages with tons of internal links leading to pages with tons of internal links. While our users enjoy the ability to navigate this world according to these relationships, I am curious if we should force a more strict hierarchy for SEO purposes. Essentially, does it make sense to "nofollow" all of the horizontal internal links for a given entity page/url? For search engine indexing purposes, we have legit sitemaps that give a simple vertical hierarchy...but I am curious if all of this internal linking should be hidden via nofollow...? Thanks in advance!

            Artist Bios on Multiple Pages: Duplicate Content or not?

            I am currently working on an eComm site for a company that sells art prints. On each print's page, there is a bio about the artist followed by a couple of paragraphs about the print. My concern is that some artists have hundreds of prints on this site, and the bio is reprinted on every page,which makes sense from a usability standpoint, but I am concerned that it will trigger a duplicate content penalty from Google. Some people are trying to convince me that Google won't penalize for this content, since the intent is not to game the SERPs. However, I'm not confident that this isn't being penalized already, or that it won't be in the near future. Because it is just a section of text that is duplicated, but the rest of the text on each page is original, I can't use the rel=canonical tag. I've thought about putting each artist bio into a graphic, but that is a huge undertaking, and not the most elegant solution. Could I put the bio on a separate page with only the artist's info and then place that data on each print page using an <iframe>and then put a noindex,nofollow in the robots.txt file?</p> <p>Is there a better solution?  Is this effort even necessary?</p> <p>Thoughts?</p></iframe>

            How do 302 redirects from Akamai content targeting impact SEO?

            How do 302 redirects from Akamai content targeting impact SEO? I'm using Akamai content targeting to get people from countries and languages to the right place (eg www.abc.123 to redirect to www.abc.123/NL-nl/default.aspx where folks from the Netherlands get their localized site in dutch) and from the edge server closest to them.  As far as I know Akamai doesn't allow me to use anything but a 302.  Anyone run across this?  is this 302 a problem?  I did a fetch as googlebot on my main domain and all I see is the Akamai 302.  I can't imagine this is the first time Akamai has run across this but I would like to know for sure.
