I am building a multilingual website, and I am sure that some time ago I saw that there was a meta tag to tell search engines the URLs of the same page in another language.
I am currently using the language tag below, but is there another tag to list the same URL for pages in different languages?
<meta http-equiv="content-language" content="en">
Sort of??
<meta http-equiv="alternative-language" content="es" ref="/es/page.php">
