Choose the x-default Language for WPML hreflang Tags
Points WPML's x-default hreflang tag at the language you choose, for example English, instead of the site's default language.
Snippet Library
Multilingual snippets for WordPress
Snippets for multilingual sites: language switchers, translated strings and per-language behavior with WPML, Polylang and similar plugins. For sites that serve readers in more than one language.
Manual hreflang Links for Translated Pages
Adds a box to the editor where you list the URLs of a page's translations; the matching hreflang tags (plus x-default) are printed in the page head, for multilingual sites that do not use a translation plugin.
Polylang hreflang: Set Which Language Is x-default
Adds or replaces the x-default hreflang link Polylang prints, pointing it at the language you choose so search engines know which version to show everyone else.
Remove WPML hreflang Tags From Paginated and Filtered Pages
Stops WPML from printing hreflang tags on page 2+ of archives, search results and URLs with query strings, where the alternates often point at mismatched pages.
Suggest the Visitor's Language Version
Shows a small, dismissible banner when the visitor's browser language differs from the page language and a translated version exists (read from the page's hreflang links), with a link to switch.
