It seems that Google selectively displays location of where content of its search results is based. A search for “get sitelinks google” via Google Spain yields a page from SEO Hong Kong. But if you look at the URL details, you’ll see extra information that’s definitely not found within the URL of the search result.
That information is a location “Región Administrativa Especial de Hong Kong de la República Popular China” which my guesswork suggests is taken from where the website is hosted or located. Does this help search engine users? It’s hard to tell for now because in my opinion, what matters most is the quality of content rather than where is the website located. Maybe unless my website has the .hk domain which used to be the riskiest domain in the world. Thank goodness it’s no longer the case as of the latest research.
