Two hreflang
tag examples below:
<link rel="alternate" hreflang="en" href="www.123.com/en" />
<link rel="alternate" hreflang="es" href="www.123.com/es" />
I know this will translate an English page to a Spanish page. I then need to make it bidirectional, so a Spanish page to English. How do I make it bidirectional?
I add those two tags to my English version, but where is the 'Spanish' page? Is it automatically created once I add the Spanish tag and I then go to that page to add the hreflang
tag for the English version or do I add four hreflang
tags (en, es and es, en) on the same page etc?
(I'm learning SEO and this is a question/topic I am confused about.)
