Polylang and SEO

Hi,

first of all many thanks for your great plugin.

I use Polylang and Yoast SEO in my website (www.webfoodculture.com), it’s in two languages: English and Italian.

I’m trying to boost the SEO: it seems that Polylang “takes care of multilingual SEO such as html hreflang tags and opengraph tags”, but I don’t know how exactly it works and if I should change change settings.

Is there a manual or something to help me out with this?

Many thanks in advance.

Antonio
