I've an issue with hreflang tag. I'm working in a multilanguage site that have two languages, italian and english. I'd like to set automatically main page language in english for all the countries different from Italy.
I put this code on main page of my website but it seems doesn't work
<link rel="alternate" href="http://example.com/en/index.php" hreflang="en" />
Anyone can help me, please?
