Global brands that invest in international search engine optimization (SEO) keyword research gain a major competitive advantage in reaching new markets.

If international SEO keyword research isn’t part of your global marketing strategy yet, then keep reading to learn what it is, why it’s so important, and what tools to use—plus our top tips for getting it right. 

International SEO keyword research: More than translating briefs

International keyword research can help your content reach new audiences like never before. But you can’t simply translate your keywords from one language into another. Each market requires its own local keyword research and strategy.

To do this right, brands have to understand both what audiences are searching for and how they’re searching for it. This considers any local vocabulary or slang while also tapping into how an audience thinks when searching for something, and what platforms they use.

Localization is vital to any international keyword research strategy. You have to fully adapt your brand’s message according to each specific audience’s language, culture and context.  This requires working with a native-level speaker or agency based in your target market (more on that below).

How does international keyword research compare with domestic keyword research?

VeraContent team members

Here are three major ways international and local keyword research differ:

1. Different audiences, different needs

Every local audience has their own pop culture moments, slang and values. There might be keywords in one market that don’t exist in any other, even between markets that share the same language.  

Quick example: Is your Spanish-speaking audience searching for “ordenador” or “computadora” when they’re searching for a computer?

When researching keywords for domestic searches, there might be regional differences, but there’s much less variation and complexity than with international keyword research. 

“I’ve been working in SEO in Spanish only in Spain, so I’ve been targeting only Spain. For example, when we are working in e-commerce, we do get a lot of traffic from Latin America. But that traffic doesn’t convert. So the question that I often get is, ‘Why do we have so much traffic and yet we don’t have many conversions?’ If I was to optimize something in Spanish, I would probably target Latin America because I feel like there is a whole new world to explore.

Filipa Serra Gaspar, Spanish SEO Specialist

2. Google might reign supreme in most countries, but not all of them 

Most of the world uses Google but it doesn’t always make sense to focus on Google’s algorithm. It’s worth considering what search engines your audience actually uses. Depending on your target market, that could drastically change how (and where) you conduct keyword research. 

To give you an idea:

3. English is competitive

Considering English is the internet’s most commonly used language, it’s a fair assumption that English has a higher search volume for most keywords.

Yet that doesn’t mean other languages don’t have high search volumes. In fact, it’s possible to see nearly the same search volumes for similar keywords in English and another language—but the keyword difficulty will be much lower. 

Also, non-English keywords tend to have a much lower cost-per-click (CPC). 

This is good news for multilingual marketers! It means the audience is out there searching, but the competition is much less fierce than it is in English.

Do you need to be a native speaker to do international keyword research?

Native linguists and translators are invaluable to the international keyword research process. They understand better than anyone what users in their target market are thinking and searching for. 

“I have never offered international keyword research because I wouldn’t rate my Spanish level as high enough to do a thorough job. Good keyword research requires working out how the person you’re writing for would phrase their searches and requires a native-level speaker in my opinion.”

Joshua Saxon, Content Marketer & SEO Specialist

Without that on-the-ground approach, you’re likely to miss the mark. 

We recommend collaborating with a native SEO expert, either by working with a freelancer or an international SEO agency.

Which tools are best for international keyword research?

Here are 5 top tools that SEO experts recommend for international keyword research. 

1. SEMrush

Most content marketers are familiar with SEMRush. It’s one of the most popular keyword research tools, and the one possessing the largest keyword database

SEMRush works the same way regardless of which language you use. Just make sure to first select the location that you’re targeting, for example Spain. Then, the same way you would upload a list of terms in English, you can do the same with any other language.

“It gives you a decent amount of related keywords and questions, and it’s easy to move the keywords over to position tracking for reporting. SEMrush has a lot of other useful tools for digital marketing, including specific tools for local SEO, so it’s worth the monthly fee for me.”

– Joshua Saxon, Content Marketer & SEO Specialist 

A few of SEMRush’s features include:

  • Cloud-based
  • The largest keyword database, with more than 9.4 billion keywords
  • Competition analysis
  • Easy-to-read UX, making it simple to switch countries

SEMRush is a great tool, but it isn’t comprehensive. SEO experts still need to look at other research methods, such as Google autocomplete—which is another $200 a month on top of a paid plan to access traffic analytics.

Pricing: It’s free up to 10 queries a day, but $119.95 monthly for their basic premium plan. 

2. Ahrefs Keyword Explorer

Ahrefs is another top contender for an international keyword research tool. It provides tons of information based on a single seed keyword.

Like with SEMRush, make sure to select the region that you’re targeting and simply search for the keywords in any language. It’ll then bring up the popularity of the keyword in the region you selected as well as other popular regions. For example, when searching for a keyword in French, it’ll often show the keyword’s popularity in all French-speaking regions, including France, Canada and Belgium.

Its features include:

  • Competition analysis, including first-page breakdowns sorted by country
  • Complex difficulty score, with information on how many backlinks are needed to rank on the first page of search engine results
  • Data for 10 search engines, including top search engines for other countries like Yandex and Baidu
  • The interface supports 13 languages, including English, German, Spanish, French, Italian, Japanese, Chinese, Dutch, Polish, Portuguese, Russian, Swedish, and Turkish.

While it’s a great tool, some of its drawbacks include keyword suggestion uniformity and limited keyword ideas—especially in the context of international SEO keyword research. The cheapest plan is still quite expensive and doesn’t offer ranking data from the past.

Pricing: Around $95 per month for the ‘Lite’ plan.

3. Moz

Keyword research tool, Moz

The people behind Moz started as bloggers, and Moz has been a pioneering SEO tool ever since. 

With Moz, you can also specify the location and language. As in the example in the image above, you can specify “United States – en-US.”

It offers:

  • A large and accurate keyword database 
  • Customized reports with SEO suggestions 
  • Competition analysis
  • A link explorer, which can help with SEO link building and researching competitor backlinks
  • A website crawling tool that checks your website for errors and missed opportunities

Moz is meant to be an end-to-end SEO solution, aimed at large enterprises with devoted SEO teams. Because of this, it has a steeper learning curve than other SEO tools and can be overkill for smaller companies. While it offers a ton of features that would be useful for international keyword search, it’s targeted to US audiences and has a lack of data for foreign search queries. 

Pricing: Starts at $99 per month for their Pro Standard plan. 

4. Google Keyword Planner

Example of Google Keyword Planner

If you want to rank highly on Google, then what better keyword planner to use than Google’s own? The Google Keyword Planner allows you to search for keywords in a specific location and language.

Google Keyword Planner includes a couple of great features, including:

  • Totally free, no matter how many queries per month
  • Offers integration with Google Ad Campaigns
  • Allows you to access historical data from up to 12 months ago
  • Trusted to be accurate and reliable

As a free tool, it won’t offer the same robustness of features as other international keyword research tools do, such as competition analysis. Plus, if a business is working in regions where Google isn’t the top search engine, it might not make much sense to use. 

Still, it’s a great add-on tool to use in conjunction with the paid tools.

How to conduct thorough international keyword research

Here’s our step-by-step guide on how to conduct thorough international SEO keyword research. 

1. Keep relevancy in mind as you research

If your content isn’t relevant to users, it won’t rank. Google ranks pages based on their relevance to searcher’s queries.

First, look at your target markets and your industry. If you’re thinking, “I want to translate our keywords into Spanish,” ask what kind of Spanish.

What countries are you targeting? And within those countries, will your international marketing strategy appeal to different dialects and regional differences? Understanding user intent and needs will go a long way as you brainstorm keywords.  

“Search volumes given by any tool is usually just indicative as to its popularity against other keywords to help you work out where to focus. Aside from looking at search volumes and CPC, it’s important to speak to your customers and find out what questions they have. Check email threads for questions that could be turned into useful posts, even if tools like SEMrush say there’s zero volume.”

– Joshua Saxon, Content Marketer & SEO Specialist

2. Look at your competitors

Your competitors are doing their own keyword research, and you can learn from what content they’re putting out. 

Research who your biggest competitors in a market are, then look at what keywords they’re using. Performing keyword gap analysis can help you identify holes in your keyword planning strategy. Some SEO tools, like SEMrush, offer built-in competitor analysis metrics that will help you do this.  

3. Localize your keywords

VeraContent’s CEO, Shaheen Samavati, and head of business development, Kyler Canastra, discuss when to create content from scratch vs. translate it during this podcast episode.

Localizing keywords means adapting existing keywords from one language to another with all the behavioral and cultural context in mind. 

To localize keywords, an international SEO specialist has to pay close attention to how people are searching. 

Finding successful keywords for a market can be a fine line. One study focusing on German keywords found that searching for “make your lips look bigger” produced a monthly search volume of 20. Meanwhile, “how to make your lips bigger” has a monthly search volume of nearly 1,200. It’s a small change, but the latter keyword volume demonstrates how a native speaker is more likely to ask questions according to the syntax and vocabulary that feels natural to them.

It often takes a native eye to spot these opportunities because a marketer needs to be intimately familiar with a language’s common phrases, slang and tone in order to pull this off.

4. Review the viability of your keywords

Keyword search volume changes, and so does Google’s algorithms. Which is why keyword research is not a one-time process. To keep content ranking highly, you need to review your keywords regularly. 

More and more keywords are encrypted by Google every day. With this in mind, another way to generate new keyword ideas is to look at your own website and review what is successful. What pages or keywords are your target readers finding most often on your site? Understanding SEO keyword popularity for your specific niche is key to increasing your ranking.

Traffic analytics tools, like those offered by Ahrefs or Google Analytics, collect the terms people are using to find your website and present them in your organic search traffic results. 

5. Consult an international SEO agency

An expert eye is the most valuable part of the international keyword research process. But how do you incorporate an international SEO specialist into your workflows?

Most companies either work with freelance native SEO specialists or partner with an international SEO agency. With an agency, you get access to a wide pool of vetted translators and linguists of many languages. 

“As multilingual marketers, we can’t be experts in every language and market. But we can be experts at finding the right professionals who are.”

Shaheen Samavati, Co-founder and CEO of VeraContent

Bonus tip: Keep a clean international SEO URL structure 

Establishing an efficient and logical SEO URL structure can also help new audiences find your content. After all, the URL is what your audience is going to see first. 

We always recommend international businesses have a language or country indicator in their URLs. For example, if your website is, the Italian version can look like:

Using targeted keywords in the slug also helps Google and readers find pages easily. If the keyword for an article is “best ice cream in New Orleans,” then your URL could look like “”

Good international SEO also involves hreflang tags, which are attributes that help search engines identify what language your content is in.
