- Metatag: hreflang
- -----------------
- This module automatically adds hreflang meta tags for each locale currently
- enabled on the site. It also provides support for the hreflang=x-default meta
- tag.
- This is similar to the Alternative hreflang [1] module. That module
- automatically adds the hreflang tag to every page for every enabled locale,
- which may not be what a site needs. This module allows the site builder control
- over what tags are shown.
- The module also provides new tokens to output the URLs of each of the current
- node's translations, and assigns these as the defaults for the meta tags. As
- such, this module may not need additional configuration once it is enabled, but
- it's always worth confirming the output is as expected.
- This module works best when the Translation or Entity Translation modules are
- enabled and configured.
- Configuration
- --------------------------------------------------------------------------------
- 1. By default if the hreflang="x-default" meta tag matches one of the
- hreflang="LANGCODE" meta tags that hreflang="LANGCODE" meta tag will be
- removed. It is possible to change this so that the meta tag is not removed
- by enabling the "Allow hreflang tag that matches the x-default tag" option
- on the main Metatag settings page:
- admin/config/search/metatags/settings
