Hey, in recent days I've started noticing Google serving the wrong page for specific functions in the search results. It served me the german and portuguese versions of page when I was clearly searching in english with a browser that's set to english. I think this could be helped by implementing hreflang across php.net:
https://support.google.com/webmasters/answer/189077?hl=en because of how the php.net structure works, I think this could actually be quite simple for large groups of pages, for instance, this page: http://us2.php.net/manual/en/function.version-compare.php would have hreflang tags like this, the first one being self referencing: <link rel="alternate" hreflang="en" href=" http://php.net/manual/en/function.version-compare.php"; /> <link rel="alternate" hreflang="pt-BR" href=" http://php.net/manual/pt_BR/function.version-compare.php"; /> <link rel="alternate" hreflang="es" href=" http://php.net/manual/es/function.version-compare.php"; /> <link rel="alternate" hreflang="de" href=" http://php.net/manual/de/function.version-compare.php"; /> (Leaving out the us2. subdomain so people would redirect to their appropriate servers) etc. You could also add a redirector URL like this: <link rel="alternate" hreflang="x-default" href=" http://php.net/manual/function.version-compare.php"; /> Which Google would then send people to if it didn't know what the correct language for that person is. Would be happy to provide help / more info if needed! Best Joost -- Joost de Valk Founder & CEO, Yoast
