Localization Strategy Template for PMs

Start with markets that already show organic demand: inbound trials, website traffic, sales inquiries, or support tickets in a non-English language. Cross-reference demand signals with revenue potential and localization complexity. A market with high demand and low complexity (e.g., a shared-language market like Canada for French) is a better first bet than a high-complexity market with unproven demand.

Start with the subset that matters most for conversion. For most SaaS products, that means the signup flow, core product UI, billing pages, and top 10-20 help articles. Marketing pages and secondary features can follow after you validate that local users convert and retain. Use [analytics](/analytics-guide) to track drop-off points by locale and prioritize accordingly.

Costs vary widely depending on language, scope, and quality requirements. Professional translation of UI strings for a mid-size SaaS app (5,000-10,000 strings) runs $5,000-$15,000 per language. Add help docs, marketing pages, legal review, and ongoing maintenance, and budget $20,000-$50,000 per market for a first launch. Machine translation with human review can reduce costs by 40-60% for non-critical content.

[Internationalization](/glossary/customer-segmentation) (i18n) is the engineering work that makes your product capable of supporting multiple languages and locales: extracting strings, handling date/number formats, supporting RTL layouts. Localization (l10n) is the content and design work of adapting the product for a specific market: translating text, adapting imagery, adjusting pricing. I18n is a prerequisite for l10n. You do i18n once; you do l10n per market.

Track three categories of metrics. First, adoption: trial signups and activation rates by locale compared to your English baseline. Second, revenue: conversion rate, ARPU, and total revenue from localized markets. Third, satisfaction: NPS or CSAT by region and support ticket volume in the local language. Compare each metric against the English baseline and against your pre-localization performance in that market to isolate the impact of localization from organic market growth. ---
