Link Whisper now works with sites in languages other than English. We have specifically developed support for:
Spanish, French, German, Russian, and Portuguese.
Perhaps this doesn't sound like much, but it took significant development time to add support for each language. What this means is that if you have a Spanish or other language site, you can expect internal link suggestions that make much more sense for your site.
Better internal links = better rankings.
Since this is a brand new feature, we do expect that there may be some needed tweaks. If you have a foreign language site that you end up testing this on, please let us know if something doesn't quite seem right and we'll get it fixed right away. (Simply go to "updates" on your WordPress dashboard to get our latest version).
To designate your site as a language other than English, simply go to the settings page and select your language from the "Selected Language" dropdown menu.
Overall, feel free to start using this new feature on your foreign language sites!
