      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

          Hreflang tags and canonical tags - might be causing indexing and duplicate content issues

          Hi, Let's say I have a site located at https://www.example.com, and also have subdirectories setup for different languages. For example: https://www.example.com/es_ES/ https://www.example.com/fr_FR/ https://www.example.com/it_IT/ My Spanish version currently has the following hreflang tags and canonical tag implemented: My robots.txt file is blocking all of my language subdirectories. For example: User-agent:* Disallow: /es_ES/ Disallow: /fr_FR/ Disallow: /it_IT/ This setup doesn't seem right. I don't think I should be blocking the language-specific subdirectories via robots.txt What are your thoughts? Does my hreflang tag and canonical tag implementation look correct to you? Should I be doing this differently? I would greatly appreciate your feedback and/or suggestions.

          Can you target the same site with multiple country HREFlang entries?

          Hi, I have a question regarding the country targeting aspect of HREFLANG. Can the same site be targeted with multiple country HREFlang entries? Example: A global company has an English South African site (geotargeted in webmaster tools to South Africa), with a hreflang entry targeted to "en-za", to signify English language and South Africa as the country. Could you add entries to the same site to target other English speaking South African countries? Entries would look something like this: (cd = Congo, a completely random example) etc... Since you can only geo-target a site to one country in WMT would this be a viable option? Thanks in advance for any help! Vince

          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

          Multiple hreflang tags

          I'm trying to advise on the multi country seo for a site in terms of markup. We've already decided on using sub folders rather than separate sites or subdomains due to an established link profile and good rankings in all countries. The question is in relation to the homepage. Obviously this is the page most likely to rank well in any country (the site is a .com). But can multiple hreflang tags be put on the page to say that the page targets many countries? Or would leaving the hreflang tag off allow it to just rank for all countries? Also do Yahoo and Bing follow hreflang tags? I can't find any info on this anywhere! Thanks very much in advance for any help!

          SEO for Subdomains for different languages .com/fr, .com/es

          Hi All, I was wondering how best to to approach optimisation of a site that exists on a single .com domain, but has different subfolders for different languages. The site is a .com and it has subfolders for French, Spanish, Russian and English.  The business is situated in France and the vast majority of clients are French and English speakers. I've read that it's possible to geo target these subfolders using webmaster tools however I believe this is an inferior method of optimisation than having tld's.  Just wondered if anyone had experience of htis and could provide any advice ?   As they won't be rebuilding the site for another year or so I wondered if there were any quick wins? My second question is to do with how best to set these campaigns up within SEO Moz. would it be better to track at a subdomain or subfolder leverl (for different languages)? If someone could advise I would greatly appreciate it! Thanks, vantresca

          Optimizing terms with accents/tildes in Spanish

          Hello all, quick question.  We are optimizing for a keyword that includes an accent in Spanish.  Is it better to use the accented or regular form (i.e. inglés vs. ingles)?  Also, is there any distinction between accents (áéí...) and the ene (ñ) in terms of strategy/best practices?  Does this accent issue have a huge impact on ranking?
