A site can be multilingual without being multi-regional (serving the same country in two languages both widely spoken there) or multi-regional without being multilingual (the same language across different countries with different pricing or regulations) — the two problems require overlapping but not identical solutions, both typically involving hreflang tags to connect language/region variants correctly. Machine-translated content without human review carries real risk: beyond simple accuracy issues, poor or literal translations often miss the actual keywords and phrasing native speakers use to search, meaning a technically correct translation can still target the wrong keywords entirely for that market. High-quality multilingual SEO generally requires either native-speaking writers or at minimum a native-speaker review pass over machine-translated drafts, plus market-specific keyword research rather than a direct translation of the source-language keyword list.
Example
A company machine-translates its English blog into Spanish, then discovers native Spanish speakers actually search using different phrasing entirely — requiring a market-specific keyword research pass rather than a literal translation of the English keyword list.
