# Hreflang Search engines use `` tags to serve the correct language or regional URL in search results. Hreflang is a simple module that automatically adds these tags to your pages. It has no dependencies, but works well with Entity Translation module. More info about hreflang can be found at the article "[Use hreflang for language and regional URLs](https://support.google.com/webmasters/answer/189077)." To file a bug report, feature request or support request for this module, please visit the [module project page](https://www.drupal.org/project/hreflang). # Requirements No special requirements. # Installation A few days after installing this module, you should see a message reading "Currently, your site has no hreflang tag errors" at [Google Webmaster Tools](https://www.google.com/webmasters/tools/i18n). # Configuration If for some reason you'd like to modify the hreflang tags on a page, you can do so by implementing the core `hook_language_switch_links_alter()` or `hook_html_head_alter()` hooks in a custom module. If you would like to add an additional `hreflang="x-default"` tag pointing at your site's default language, go to the settings page at admin/config/search/hreflang and enable the "Add x-default hreflang tag for default language" setting.
