Welcome to the Q&A Forum

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.

If I download a CSV output of the external links and the characteristics of them, the output is mixed up. When I put the data in Columns, some columns are disordered. Do more people experience these problems? Is there some preference I have to adapt? Thanks! SFCTf
