Cross-Language Density

Definition

Cross-language density measures how search demand for a concept distributes across its equivalents in different languages. Rather than literal translations, it compares semantically equivalent search terms that native speakers actually use in each language.

Why It Matters for SEO

A keyword with moderate volume in English might have massive untapped demand in Portuguese or German with lower competition. Cross-language density analysis reveals international opportunities that monolingual keyword research misses entirely.
