      Hi Mozzers,

      I have a question about the rel="alternate" hreflang tag, with an example.

      When I use two subfolders for two different countries/languages, for instance www.domain.com/nl-nl/ and www.domain.com/nl-en/ (for the English version) and I want to use the rel="alternate" hreflang tag, do I need to follow the ISO standards concerning Uppercase country code and Lowercase language code (en-NL)? Or is it okay to use the Lowercase country and language code (en-nl), since we also use this in the URL of the Subfolder.

      What does Google prefer?

      Thanks in advance.

        Hey there, Lowercase is fine.

        Not sure why you would have /nl-nl/ and /nl-en/ though, it's either English or Dutch, right?

        I've set this up many times before and it works just fine, although it's sometimes a little overkill unless you have the English version of a page ranking higher than the Dutch version in Google.nl for example.

        I usually find adding these as separate websites in WMT's and setting the target country correctly for each site you shouldn't have any problems.

        So add http://www.domain.com/nl/ as its own site in WMT and set target country to Netherlands, then add http://www.domain.com/en/ as another site and set its target country to UK.

        Hope this helps,

        Goodluck,

        Woody 🙂

          Should Hreflang x-default be on every page of every country for an International company?

          UPDATED 4/29/2019 4:33 PM I had made to many copy and pastes. Product pages are corrected Upon researching the hreflang x-default tag, I am getting some muddy results for implementation on an international company site  older results say just homepage or the country selector but…. My Question/Direction going forward for the International Site I am working on:  I believe I can to put x-default all the pages of every country and point it to the default language page for areas that are not covered with our current sites. Is this correct? From my internet reading, the x-default on every page is not truly necessary for Google but it will be valid implemented. My current site setup example:
          https://www.bluewidgets.com Redirects to https://www.bluewidgets.com/us/en (functions as US/Global) Example Countries w/ code Site:- 4 countries/directories US/Global, France, Spain Would the code sample below be correct? https://www.bluewidgets.com/us/en/ (functions as US/Global) US/Global Country Homepage - https://www.bluewidgets.com/us/en/ US/Global Country Product Page(s) This would be for all products - https://www.bluewidgets.com/us/en/whizzer-5001/ http://www.bluewidgets.com/us/en (functions for France) France Country Homepage - https://www.bluewidgets.com/fr/fr/ France Country Product Page(s) This would be for all products- https://www.bluewidgets.com/es/es/whizzer-5001 http://www.bluewidgets.com/us/en (functions as Spain) Spain Country Homepage - https://www.bluewidgets.com/es/es/ Spain Country Product Page(s) This would be for all products - https://www.bluewidgets.com/es/es/whizzer-5001 Thanks for the spot check Gravy

          Redirect to 'default' or English (/en) version of site?

          Hi Moz Community! I'm trying to work through a thorny internationalization issue with the 'default' and English versions of our site. We have an international set-up of: www.domain.com (in english) www.domain.com/en www.domain.com/en-gb www.domain.com/fr-fr www.domain.com/de-de and so on... All the canonicals and HREFLANGs are set up, except the English language version is giving me pause. If you visit www.domain.com, all of the internal links on that page (due to the current way our cms works) point to www.domain.com/en/ versions of the pages. Content is identical between the two versions. The canonical on, say,  www.domain.com/en/products points to www.domain.com/products.  Feels like we're pulling in two different directions with our internationalization signals. Links go one way, canonical goes another. Three options I can see: Remove the /en/ version of the site. 301 all the /en versions of pages to /. Update the hreflangs to point the EN language users to the / version. **Redirect the / version of the site to /en. **The reverse of the above. **Keep both the /en and the / versions, update the links on / version. **Make it so that visitors to the / version of the site follow links that don't take them to the /en site. It feels like the /en version of the site is redundant and potentially sending confusing signals to search engines (it's currently a bit of a toss-up as to which version of a page ranks). I'm leaning toward removing the /en version and redirecting to the / version. It would be a big step as currently - due to the internal linking - about 40% of our traffic goes through the /en path. Anything to be aware of? Any recommendations or advice would be much appreciated.

          Redirect the main site to keyword-rich subfolder / specific page for SEO

          Hi, I have two questions. Question 1: is it worthwhile to redirect the main site to keyword-rich subfolder / specific page for SEO? For example, my company's webpage is www.example.com. Would it make sense to redirect (301) the main site to address www.example.com/service-one-in-certain-city ? I am asking this as I have learned that it is important for SEO to have keywords in the URL, and I was thinking that we could do this and include the most important keywords to the subfolder / specific URL. What are the pros and cons of this? Should I create folders or pages just the sake of keywords? Question 2: Most companies have their main URL shown as www.example.com when you access their domain. However, some multi-language sites show e.g. www.example.com/en or www.example.com/en/main when you type the domain to your web browser to access the site. I understand that this is a common practice to use subdomains or folders to separate different language versions. My question is regarding subfolders. Is it better to have only the subfolder shown (www.example.com/en) or should I also include the specific page's URL after the subfolder with keywords (www.example.com/en/main or www.example.com/en/service-one-in-certain-city)? I don't really understand why some companies show only the subfolder of a specific language page and some the page's URL after the subfolder. Thanks in advance, Sam

          Cross domain rel alternate, will it help or hurt?

          I have a website that has similar pages on a US version and a UK version. Currently we want Uk traffic to go to the US, but the US domain is so strong it is outranking the UK in the UK. We want to try using rel alternate but have some concerns. Currently for some of our keywords US is #1, UK is #4. If we implement rel alternate, will it just remove our US page? We don't want to shoot ourselves in the foot and lose traffic. Is this worth doing, will it just remove our US ranking and our double listing? Any anecdotes, experiences or opinions are appreciated. Thanks.

          Which hreflang tag to use for .eu domain

          Hi there, We're trying to solve a problem with one of our domains, we have a .eu CCTLD and we're trying to implement hreflang tags. On our US and UK sites, we use "en-us" and "en-gb", but it's not clear how to approach this european problem, as there is not a "en-eu" tag. The site is in English, but serves several European countries speaking different languages. What's the best hreflang code to use in this situation? Any help much appreciated, Thanks!
