On the Guardian.co.uk homepage they have:
<link rel="alternate" href="https://www.theguardian.com/uk" hreflang="en-GB"/> <link rel="alternate" href="https://www.theguardian.com/us" hreflang="en-US"/> <link rel="alternate" href="https://www.theguardian.com/au" hreflang="en-AU"/>
Each page displays different content. UK, US and AU show stories related to each country. Shouldn't the
hreflang attribute show the same page with the same stories however those stories should be translated accordingly into the correct language? (Not the best example as UK, US and AU are similar) but strictly speaking, shouldn't it show the same content with the language changed?
