How to Do Keyword Research Across Multiple Countries and Languages

Why Does International Keyword Research Matter?

A keyword that performs well in one country may have little demand or a different meaning in another.

Even when people search for the same service, they may use different terminology, sentence structures or levels of detail. For this reason, international keyword research cannot be completed by translating a list of English keywords word for word.

Each country and language must be researched as an individual search market.

Separate Countries From Languages

Language and location are not the same targeting factor.

English-speaking users in the United States, the United Kingdom and Australia may use different words for the same product or service. A country may also include audiences searching in several languages.

Begin by defining specific country-language combinations, such as:

• English for an international audience

• Italian for Italy

• Albanian for Albania

• Greek for Greece

This structure makes multilingual keyword research more precise and prevents data from unrelated markets from being combined.

Begin With Services and Search Intent

Create an initial list based on the company’s services, products and customer needs.

For each topic, consider what the user wants to accomplish:

• Learn about a subject

• Compare different solutions

• Find a local provider

• Request a quotation

• Purchase or book a service

• Solve a specific problem

Understanding search intent by country is essential because similar phrases may represent different expectations in different markets.

A high-volume keyword is not automatically valuable if it does not match the service or the customer’s stage in the decision process.

Research Each Language Independently

Do not translate the final keyword list from one language into another.

Instead, use the translated service or topic only as a starting point. Then research how native speakers genuinely search for it.

Professional keyword localization should consider:

• Natural local terminology

• Singular and plural variations

• Formal and conversational language

• Regional expressions

• English words commonly used locally

• Service and location combinations

• Questions asked by potential customers

The most grammatically accurate translation is not always the phrase people enter into Google.

Analyse Local Search Demand

Google Keyword Planner can generate related keyword ideas and provide estimates for monthly searches and advertising costs. These figures can help compare potential demand, but Google notes that performance is also influenced by factors such as location, competition and customer behaviour.

When conducting local keyword research, configure the relevant country and examine each market separately.

Compare:

• Estimated search demand

• Competition

• Commercial relevance

• Local intent

• Seasonality

• Long-tail variations

Low-volume terms should not be rejected automatically. A specific phrase with clear commercial intent may be more valuable than a broad keyword attracting an unfocused audience.

Use Google Trends to Compare Local Terminology

Google Trends can help compare alternative terms and identify regional differences.

Its regional results show where a term has a higher relative level of interest. However, the values represent relative popularity within a location rather than absolute search volume.

Google Trends also treats different spellings and variations as separate searches unless they are deliberately combined.

Use it to compare:

• Alternative translations

• Local and international terminology

• Singular and plural forms

• Industry-specific vocabulary

• Seasonal changes in interest

Review the Actual Search Results

Search each potential keyword using the correct country and language settings.

Analyse the pages that already appear:

• Are they articles, service pages or product pages?

• Are the results local or international?

• Do maps and business listings appear?

• Are competitors targeting the same phrase?

• Does Google interpret the keyword as informational or commercial?

The results page reveals how the search engine understands the query. If the existing results do not match the page you plan to create, the keyword may have the wrong intent.

Build a Separate Keyword Map for Every Language

Once the research is complete, assign a primary keyword and supporting keywords to each page.

The same page may target different phrases in different languages. Its structure, title and message should remain consistent, but the keywords should reflect the behaviour of the local audience.

An effective international SEO strategy should localize:

• SEO titles

• Meta descriptions

• Headings

• Page copy

• Image alt text

• URLs where appropriate

• Internal link text

• Calls to action

Google recommends using separate URLs for each language version and identifying localized alternatives with hreflang. It also determines page language primarily from visible content, making complete and natural localization important.

Avoid Keyword Competition Between Pages

Multiple pages in the same language should not target the same primary keyword without a clear reason.

Create a keyword map showing:

• Country

• Language

• Page

• Main keyword

• Secondary keywords

• Search intent

• Content format

This helps prevent several pages from competing for the same query and makes future content planning easier.

Common International Keyword Research Mistakes

Frequent mistakes include:

• Translating keywords literally

• Combining data from different countries

• Selecting terms only by search volume

• Ignoring regional vocabulary

• Using the same metadata in every language

• Failing to analyse search intent

• Publishing translated pages without local quality control

A specialist partner such as Fiori Agency can coordinate keyword research, professional localization and multilingual content across several markets.

Final Thoughts

Effective international keyword research treats every country and language as a distinct market.

Businesses should research natural local terminology, confirm search intent and assign the most relevant keywords to each localized page. This creates content that does more than read correctly—it reflects how people actually search.
