What is multilingual SEO?
Multilingual SEO is the discipline of optimizing a website for organic visibility across multiple languages — treating each language as its own SEO program rather than a translated version. It includes native-speaker keyword research per language, locally-authored content, per-locale technical optimization, hreflang implementation, and locale-aware structured data.

Search behavior differs by language. A keyword that's transactional in English may be informational in Japanese. The competitive set differs. The SERP features differ. Even the buyer journey differs.
Most "multilingual SEO" services are translation projects with SEO bolted on. We work the other way. Each language starts with native keyword research. Content is authored locally, not translated. The technical layer — proper hreflang implementation — sits underneath to keep Google routing the right locale to the right user.

Multilingual SEO questions.
Why not just translate our existing English content?
Translation produces text that's grammatically correct but contextually off. We've seen translated sites underperform locally-authored sites by 60-80% in equivalent ranking positions.
Can you work with our existing translation vendor?
Yes. We work alongside your existing translators. We add the SEO layer: keyword research, on-page optimization, schema localization, and quality review.
How many languages can you support at once?
We've run programs in 12+ simultaneous languages. We typically recommend a phased rollout (3-4 languages per quarter) for cleaner execution.
What about dialects (Brazilian vs European Portuguese)?
These are distinct SEO programs. The keyword sets differ, the search behavior differs. We treat each dialect as its own language for SEO purposes.
