Good morning,
I am trying to use hreflang in the header, I have inserted the hreflang in the content setting page. To work correctly must I set, in advanced setting, “Merge with site header” on?
They can be inserted in the <head> section of every html page that has a translation.
If they are correct and are inserted in the right position of each page, then Google should see them and show their status in: Search Console, International Targeting.
Thanks a lot Tom! I realized now that I was confusing header and head. So I will remove the hreflang from the header and try to use the plugin you suggested.
