Wikipedia ILL Link: The Interlanguage Link Template Explained

Normally, linking to an article that doesn't exist creates a red link. With {{ill}}, readers see the red link to the missing English article plus a small bracketed link to the existing article in another language. Once someone creates the English article, the template simply links to it.

{{ill|English title|language code|Title in that language}}

Example: a German company without an English article:

{{ill|Example GmbH|de|Example GmbH}}

This renders as Example GmbH [de]. The first part points to the future English article, and the [de] link opens the German Wikipedia article.

• Use multiple language pairs to link several editions: {{ill|Title|de|Titel|fr|Titre}}
• Use the lt= parameter to change the displayed text.
• Language codes follow Wikipedia's subdomains: de, fr, es, ja, and so on.

Interlanguage links connect Wikipedia articles to each other. They don't link to external websites, so they aren't backlinks. They matter if your brand has an article in another language: an {{ill}} reference in English articles makes that entity visible to English readers and editors, and it often comes before an English article is created.
