Going global is an exciting step for any business, but reaching customers across borders means more than just translating your website. To truly connect with a worldwide audience, you need to understand how they search. This is where international SEO keyword research comes in. It’s the art and science of uncovering the specific words and phrases people in different countries use to find products, services, and information online.

With over 5.5 billion internet users worldwide and organic search driving about 53% of all website traffic, mastering global search is not just an option; it’s a massive growth opportunity. Let’s dive into how you can build a powerful international SEO keyword research strategy that speaks your customer’s language, wherever they are.

What Is International SEO Keyword Research?

International SEO keyword research is the process of finding and analyzing the search terms that audiences use in different countries and languages. Unlike standard keyword research that might focus on a single region, this global approach accounts for critical linguistic and cultural differences.

Think of it this way: simply translating your English keywords might only get you 10% of the way there. Real success comes from adapting to local needs, cultural quirks, and unique search habits. When you get it right, search engines can deliver your most relevant, localized pages to users based on their location, creating a seamless connection with new customers across the globe.

Step 1: Selecting Your Target Market and Language

Before you can find the right keywords, you need to know where you’re looking. The first step in any international SEO strategy is selecting your target markets and languages. Instead of trying to take on the whole world at once, prioritize countries or regions that align with your business goals.

This decision is crucial because a huge majority of people prefer to browse and buy in their native language. Consider these facts:

• About 72% of consumers spend most or all of their time on websites in their own language.
• A staggering 87% of global customers won’t buy from a website that is English only.

This creates a significant opportunity. While English content makes up nearly half of all websites, only about 16% of the world’s population speaks English. By providing high quality content in languages like Spanish, German, or Japanese, you can fill a content gap and stand out in underserved markets.

Step 2: Understanding Local Search Behavior and Intent

How people search varies dramatically from one culture to another. Understanding local search behavior and intent means digging into the why and how behind searches in each target market. A keyword strategy that works in the U.S. might fall flat in Japan if it doesn’t align with local habits.

For example, searchers in the U.S. or UK often use direct, transactional queries like “buy best laptop”. In contrast, German users may start with more informational queries like “which laptop suits me?”. In Japan, consumers value deep research, often searching for detailed reviews and product rankings before making a purchase. For practical tips, see our guide to keyword research for the Japanese market.

Cultural norms also play a big role. In many Asian cultures, users value community input and may search for forums or reviews as part of their buying journey. By aligning your SEO approach with how locals actually search, you meet their needs more effectively and increase your chances of ranking.

Step 3: Running Competitor Analysis and Finding Keyword Gaps

Your competitors at home are not always your competitors abroad. In international SEO keyword research, competitor analysis involves researching local players in each target market to find valuable keywords they rank for that you don’t. This is known as finding the keyword gap. You can quickly surface these gaps with BubbleShare’s Detail Search.

This process is one of the fastest ways to build a relevant keyword list. If your competitors have already done the hard work of finding what resonates with a local audience, you can learn from them and create even better content to compete.

Research shows that search results are highly localized. A 2024 study found that 56% of the top three Google results were country specific domains (like .de for Germany or .co.uk for the UK). This means your biggest search competitor in France might be a local French company you’ve never heard of. By analyzing these local winners, you can uncover a roadmap of content topics and keywords to capture traffic you’re currently missing.

Step 4: Mastering Keyword Identification for Each Locale

Keyword identification is about pinpointing the exact terms people use in each target market. It’s about learning the local lingo. Even within the same language, vocabulary can change dramatically from one place to another.

The differences between American and British English are a classic example:

• Americans search for a “cell phone,” while Brits look for a “mobile phone.”
• A U.S. user searches for “rental car,” while a UK user searches for “car hire.”

The same is true for Spanish. An ecommerce team found that the most effective keywords on Amazon Spain were completely different from those on Amazon Mexico because of distinct local vocabulary.

Start with Seed Keywords for Each Market

Your first move is to identify seed keywords. These are broad, foundational terms that describe your main topics or products. For a shoe company, seed keywords in the UK might include “running shoes,” “mens trainers,” and “leather boots.” For the Japanese market, you would brainstorm the local equivalents, which might involve different concepts or categories altogether. These seed keywords are not what you will ultimately target, but they are the starting point you will use in keyword research tools to uncover hundreds of more specific, long tail variations.

Keyword Translation vs. Keyword Localization

When expanding globally, many businesses make the mistake of simply translating their keywords. While it seems logical, there’s a crucial difference between translation and true localization.

The Pitfalls of Simple Keyword Translation

Keyword translation is the literal, word for word conversion of a keyword from one language to another. For example, translating “running shoes” into Spanish gives you “zapatos para correr.” While technically correct, this direct translation might not be what people actually type into a search bar. It often fails to capture the true search intent or common phrasing that a native speaker would use. Relying on translation alone is a common mistake that leads to missed opportunities and low relevance.

Why Keyword Localization is the Goal

Keyword localization goes much deeper. It’s the practice of adapting your keywords to fit the local language, cultural context, and search habits of a specific market. It’s about finding the equivalent phrase that locals use, which might be completely different from a literal translation.

Effective localization pays off. Websites that publish culturally localized content can see up to a 70% increase in organic traffic. Furthermore, 72% of consumers are more likely to buy a product if the information is in their language. Localization builds trust and shows customers that your content was made just for them.

Step 5: Evaluating Keyword Viability by Country and Language

Not all keywords are created equal, a lesson central to international SEO keyword research. A high value keyword in one market might be useless in another. Evaluating keyword viability means assessing whether a term is worth targeting in a specific country and language. This involves analyzing local search volume, competition level, and relevance to your business goals.

Analyze Key Keyword Metrics

To evaluate keywords properly, you need to look at specific data points for each market.

• Search Volume: This metric shows how many times a keyword is searched for per month in a specific country. The term “winter jacket” will have far higher search volume in Canada than in Australia.
• Keyword Difficulty: This score, often out of 100, estimates how hard it will be to rank on the first page of search results. A keyword might have huge potential in a market where there are few high quality pages ranking for it.
• Cost Per Click (CPC): This shows how much advertisers are willing to pay for a click on an ad related to the keyword. A high CPC often signals strong commercial intent, meaning the searcher is looking to buy something.

Beyond these metrics, consider trends and seasonality. Google Search Console can reveal if a term is suddenly gaining traction in a certain country, signaling a ripe opportunity to create targeted content.

Choosing the Right International Keyword Research Tool

An international keyword research tool is software designed to help you find and analyze keywords across multiple countries and languages. These tools are essential for planning and executing a global SEO campaign efficiently.

When choosing a tool, look for a few key features:

• Broad Database Coverage: Does it include data for the countries and languages you’re targeting? Does it pull data from local search engines like Naver or Baidu?
• Cross Comparison: Can you easily compare search volume and other metrics for a keyword across several markets at once?
• Local SERP Features: Does the tool show you if a keyword triggers special results like a featured snippet or an AI generated answer?

These features help you centralize your research and make decisions driven by data on a global scale.

Popular International Keyword Research Tools

Several platforms offer robust international capabilities.

• Google Keyword Planner: A free tool from Google that provides search volume data and CPC estimates directly from the source. It is a great starting point for any campaign.
• Semrush: Offers a massive keyword database covering over 140 countries, along with deep competitor analysis and keyword gap features.

Step 6: Analyzing the Local SERP in Your Target Country

What a user sees on a search engine results page (SERP) can vary significantly from one country to another. Local SERP analysis involves examining the search results in a target locale to understand the competitive landscape and what types of content Google (or the local engine) prefers to rank.

This analysis often reveals that local websites with country specific domains get a rankings boost. It also shows you what content formats are popular. In one country, videos might dominate the first page for your keyword, while in another, forums and discussion boards might rank highly. By studying the SERP your audience sees, you can tailor your content strategy to match what already works.

Beyond Google: Considering Local Search Engines by Market

While Google dominates the global search market with about a 90% share, it isn’t the top player everywhere. If Southeast Asia is a priority, here’s how to boost SEO in Southeast Asia with market specific tactics.

Here are a few key players:

• China: Baidu is the leader, commanding over 70% of the search market.
• Russia: Yandex holds around 40% of the market, competing closely with Google.
• South Korea: Naver is a major force, with users often turning to it for local, day to day searches.

Each of these engines has its own algorithm, ranking factors, and search results page layout. Naver, for example, displays results in a portal style, mixing web pages with content from its own ecosystem like Naver Blogs and Q&A sections. To succeed in these markets, you need a tailored SEO approach for each specific engine.

The Human Touch: Using a Native Linguist for Keyword Research

Automated tools are powerful, but they can’t replace human insight. A native linguist or a native speaking SEO expert acts as a crucial cultural and linguistic advisor. They can validate your keyword list to ensure the terms sound natural, carry the right intent, and don’t have any unintended meanings. If you need hands on help, explore our APAC SEO and localization services.

A native speaker can easily spot awkward phrasing or suggest more popular local synonyms. They also prevent embarrassing mistakes. For example, the English word “gift” translates to “Gift” in German, which means poison. A native linguist would catch that instantly. Professional human input is invaluable for ensuring the accuracy and quality of your keyword strategy.

Advanced Tactics: A Long Tail Keyword Strategy Across Languages

Long tail keywords are longer, more specific search phrases (usually three or more words) that individually have low search volume but collectively make up the majority of all searches. A long tail keyword strategy across languages involves targeting these niche phrases to capture highly qualified traffic.

These specific queries are less competitive and often signal strong user intent. For example, someone searching for “best budget running shoes for flat feet” knows exactly what they want.

When applying this strategy globally, it’s vital to research long tail keywords natively in each language, not just translate them from English. Uploading large seed lists via BubbleShare’s Bulk Search can speed this up. German users might use long compound words, while Japanese users may add terms like “おすすめ” (recommended) to their searches. Targeting these culturally specific long tail phrases can drive visitors who are much closer to converting.

Handling Nuances: Dialect, Spelling, and Slang Variations

Even within the same language, you’ll find differences in spelling, dialect, and slang. Acknowledging these variations is a small detail that makes a big difference in international SEO keyword research.

For example, you have “color” in the US vs. “colour” in the UK, or “apartment” vs. “flat.” While Google is smart enough to understand these are related, it often prefers to show users content that perfectly matches the language and spelling of their query.

Dialect differences are also common. In most of Latin America, the word for computer is computadora, but in Spain, it’s ordenador. Using the wrong term could mean you miss out on the entire Spanish market. Paying attention to these nuances makes your content feel truly local and builds trust with your audience.

Staying Ahead: Ongoing Keyword Review and Update Cadence

International SEO keyword research is not a one time task. Search behavior is constantly changing. Around 15% of Google searches every day are queries that have never been seen before. Setting a regular cadence, perhaps quarterly or biannually, to review and update your keyword strategy is essential for long term success.

An ongoing review should include:

• Analyzing Performance: Use Google Search Console to see which keywords are driving traffic in each country and whether your rankings are improving or declining.
• Researching Market Trends: Use keyword tools to check for changes in search volume and identify new, emerging search terms.
• Adapting to SERP Changes: The rise of zero click searches and AI generated answers is a major challenge for SEOs. Your review process should assess how these features are impacting your target keywords and adjust your strategy accordingly.

Businesses that consistently monitor their SEO efforts see much better results. One study found that companies tracking their metrics were able to grow traffic by 57% in just six months. Regular updates keep your strategy agile and aligned with what your customers are searching for right now. To help with this, tools like the BubbleShare AI Visibility Report can audit your brand’s presence in these new AI search results.

Frequently Asked Questions About International SEO Keyword Research

What is the first step in international keyword research?

The first and most important step is selecting your target markets and languages. Before you can find the right keywords, you need to decide which countries or regions offer the best opportunity for your business based on market size, demand, and cultural fit. This is the foundation of effective international SEO keyword research.

Why is keyword localization better than keyword translation?

Keyword translation is a literal, word for word conversion that often misses cultural context and local phrasing. Keyword localization is a deeper process of adapting keywords to how people actually speak and search in a specific region, which leads to higher relevance, better rankings, and more trust with the local audience.

Do I need to optimize for search engines other than Google?

Yes, if you are targeting countries where Google is not the dominant search engine. In places like China (Baidu), Russia (Yandex), and South Korea (Naver), you must create a separate SEO strategy tailored to the local search engine’s algorithm and user base.

How often should I review my international SEO keywords?

It’s best to establish a regular review cadence, such as every quarter or every six months. Search trends, language, and search engine features change constantly. Ongoing reviews help you stay current, capture new opportunities, and adapt your strategy to the evolving landscape.

What are long tail keywords and why do they matter globally?

Long tail keywords are longer, more specific search phrases. They are important globally because they are less competitive and often indicate a user with high intent. Targeting long tail keywords in different languages allows you to capture niche traffic that is more likely to convert.

How can I find out what keywords my competitors are using in other countries?

You can use an international keyword research tool with a “keyword gap” or “content gap” feature. By entering your domain and the domain of a local competitor in your target country, the tool can show you a list of valuable keywords that they rank for but you don’t.
