The US Spanish Opportunity: 42 Million Native Speakers, One hreflang Tag

~42 million US residents speak Spanish natively — more than Spain. They share your shipping zones, your payment rails and your seasons. All that’s missing on most US sites is the language.

Why this is the easiest market entry in this series

No new logistics, taxes or support hours. A Spanish version at /es/ with hreflang es-us turns existing infrastructure bilingual. Neutral Latin American Spanish works; sprinkle US-specific terms (ZIP code, not código postal alone) for polish (variants).

Who wins first

Home services, healthcare adjacent, legal, automotive, education — categories where Spanish-dominant searchers face the thinnest localized competition. Cities tell the story: Miami, LA, Houston, Phoenix.

Doing it this week

Add Spanish in the wizard, machine-translate, human-review the money pages, ship — typically an afternoon (Spanish guide). Then watch GA4’s /es/ segment justify the next language.
