Multilingual keyword research: finding the right terms in each market

The single biggest mistake in international SEO is treating keyword research as a translation exercise. The French word for "plumber" is "plombier" — but French searchers may use "dépannage plomberie" far more frequently than a direct translation of your English target keyword. Each market has its own search behaviour, and ranking internationally requires keyword research done natively in each language.

Tools for Native Language Keyword Research

• Google Keyword Planner: switch the target language and country to get local search volumes
• Ahrefs and SEMrush: set the target country for keyword explorer to see local data
• Google Search in the target country: use a VPN or google.fr, google.de to see actual SERPs
• Google Autocomplete: type your topic in the target language to see what people actually search
• AnswerThePublic: supports multiple languages for question-based keyword research
• Reddit and local forums in the target language: discover how native speakers discuss your topic

Understanding Search Volume Differences Across Markets

A keyword that gets 10,000 searches per month in English may get only 200 searches per month in the equivalent French term. This does not necessarily mean the French market is not worth targeting — it means competition may be lower and a smaller volume of high-intent searches can still drive meaningful business results. Always assess search volume in the context of the target market size, not by comparison to English volumes.

Country-Specific Terminology and Colloquialisms

Within the same language, different countries use different terms. UK English and US English differ significantly in search terminology: "skip hire" vs "dumpster rental", "solicitor" vs "attorney", "estate agent" vs "realtor". If you are targeting both the UK and Australia with English content, these differences will affect which pages rank and for what terms.
