Beyond technical aspects such as geographical targeting, hreflang and market-specific URL structures, this approach includes keyword research adapted to each language and search behaviour, alongside cultural localisation of content for each target audience.

What exactly is international SEO?

International SEO is a specialism within SEO focused on optimising business websites for companies seeking international expansion, making them visible and relevant in search engines across the countries and languages where they have commercial interests.

Although the main objective is to generate business, the aim is to connect effectively with international audiences, ensuring content is useful and relevant to users in each region.

It goes far beyond translation: content needs linguistic and cultural adaptation, taking account of local preferences, relevant search engines and each market’s particular needs.

The website’s technical setup also needs to support the process, so search engines and users can:

• Navigate the website easily, with a good experience.
• Understand the content and which country or language it targets.

Why invest in an international B2B SEO strategy? The benefits

Multilingual SEO offers tangible advantages for businesses seeking to grow their share of international markets. And the benefits extend beyond direct sales.

Here is why it matters and how it can help your business:

SEO as a pillar of international expansion

Almost any B2B business seeking to enter new countries needs to understand the importance of online activity and digital marketing in particular. Fewer businesses now operate entirely offline.

So whether you sell offline or online, your website will usually be the main showcase for your brand.

Imagine a sales activity in a new market: a trade fair, a call or a mention by a local partner. Interested prospects will often search Google for your brand, products or services.

Appearing prominently in search results can help build trust and convey authority, supporting the sales process.

Beyond your website

An international SEO campaign goes beyond optimising your own website.

It also develops your brand’s presence on relevant industry websites and local sources discussing what you offer. These mentions can add trust and authority, which matter in international trade.

In overseas markets, where potential customers may need additional reassurance before committing, that extra confidence can help you compete with established local businesses.

SEO to understand a new market

Alongside traditional research, SEO provides a useful picture of what interests your target audience.

It can help you:

Understand demand

International SEO is a strategic tool for analysing demand, potential and buyer behaviour in overseas markets before investing in them.

Keyword and search trend analysis provides evidence of interest in particular products in each country or region.

This can help assess whether your offering may gain traction in an overseas market and avoid unnecessary investment. Search data is one input, rather than a precise measure of the whole market.

Example from a client project: A client initially decided against launching a product line in Poland because the search research suggested insufficient demand, which it interpreted as insufficient business potential. This reduced launch costs. Once established, the business introduced the line as an upsell alongside other products.

Market maturity

SEO can reveal trends in a product or industry’s lifecycle by tracking changes in search patterns over time.

An increase or decrease in searches for particular products may indicate market growth or decline, helping businesses adjust their strategies accordingly.

Example: Tools such as Google Trends show how interest in particular keywords changes over time.

Entering relevant terms lets you see whether interest is increasing or decreasing, providing an indication of market maturity for those products or services.

Understand fluctuations

Multilingual SEO and the tools SEO professionals use also provide information about seasonal search patterns and trends, showing when particular products or services attract more searches.

This helps align launches and campaigns with periods of greater demand in each region.

Tools such as Google Trends also show changes in interest over time, highlighting potential growth or decline in a particular area and helping adapt the strategy and understand the product lifecycle in each market.

Example: If you are choosing between two countries for expansion, a market with seasonality that offsets your existing markets may help stabilise overall demand.

Discover potential strategic partners

SEO research can also help identify partners and other relevant organisations.

Analysing industry searches and sector-specific keywords in each country reveals businesses and other important organisations with a prominent digital presence.

This can produce a list of potential local partners for distribution, joint marketing or local adaptations of products and services.

Example: You may want to identify businesses ranking for relevant or complementary terms to explore a joint strategy. This can be particularly useful where your brand is still unknown.

Brand interest

Analysing brand interest means monitoring the frequency and volume of searches relating to a particular brand, and is an important part of international expansion.

It helps assess brand recognition in different markets, although search volume alone does not establish how people perceive the brand.

Tools can evaluate brand interest by region, providing input for assessing awareness, the effect of previous marketing campaigns and plans for future expansion.

Example: If a fashion brand sees increasing searches for its name in France, this may indicate growing interest and a market opportunity, supporting a greater marketing and expansion focus there.

SEO to analyse local competitors

SEO also enables detailed analysis of competition in each target market.

SEO tools reveal which businesses rank prominently for relevant keywords and estimate their share of search visibility, providing insight into the competitive landscape.

This shows both which businesses are visible and the content or strategies they use.

Understanding local competitors and analysing their approaches helps a business adapt its strategy to differentiate itself and stand out in search results.

For example, a B2B machinery company researching the leading search results in Germany could adapt its strategy to target categories with less competition.

International SEO to generate B2B business

This is SEO’s greatest potential contribution: turning visibility into business.

Generating business in new markets is usually the ultimate aim of international expansion, and international SEO can be an important tool in pursuing it.

As in the home market, SEO can attract visitors at different buying stages and help those visits turn into enquiries, purchases or calls.

Let us look at specific ways SEO can support international business development:

Capturing international demand

In each market, people are actively searching for solutions, products or services like yours.

An international SEO strategy works to make your website visible in target markets and improve its position in relevant search results. Greater relevant visibility can increase the chance of buyers considering your company alongside competitors; rankings are not guaranteed.

Generating demand

For many businesses or projects, including perhaps yours, content marketing can provide useful, relevant information that attracts the target audience while they research solutions at different buying stages.

SEO has an important role here.

Optimising this content can improve the search visibility of articles, guides and resources, helping potential customers discover your brand organically. This can support trust and establish your expertise in the sector.

Greater visibility and credibility

Ranking prominently in another country increases your business’s visibility in that particular market.

It can also support perceptions of trust and authority, helping local buyers view your business as a credible, relevant option.

Visibility and credibility are important when turning searches into sales opportunities, although they do not guarantee a purchase.

More precise targeting

One advantage of SEO is the ability to focus a strategy on particular segments within each country.

Keyword optimisation and adapted content can help you reach users relevant to the business, increasing the potential for conversion.

For example, a technology business could focus its international SEO on product-related searches in key cities within a large overseas country, adapting its proposition to needs and behaviours that can vary considerably between regions.

Qualified enquiries and sales

Unlike broad-reach marketing activities, search-focused SEO can reach people already interested in your type of product or service.

Enquiries from international SEO may therefore have strong relevance and purchase intent when visitors arrive through specific, relevant searches. Their quality still depends on search intent, market fit and the offering.

Long-term cost efficiency

Once your website has established search visibility, SEO can maintain a presence without paying for every advertising click.

That can make international SEO cost-effective over time, although sustainable results require investment and are not automatically low-cost.

With sound initial optimisation and regular maintenance, you can continue capturing demand overseas while working to control acquisition costs.

Supporting other international marketing channels

International SEO can also strengthen other marketing activities, both online and offline.

You can read more about the role of SEO in a multichannel strategy (in Spanish).

For example, an industrial machinery company expanding into Germany and Italy could use international SEO as the central part of attracting qualified enquiries through content adapted to each country’s language and cultural context.

It could complement this with PPC campaigns targeting local keywords, adapted social content and newsletters in each language, creating a coordinated multichannel approach to strengthen visibility and support conversions.

How do you develop an international SEO strategy?

Here are techniques for international markets that can help you improve visibility in different countries and deliver your international campaign.

Step 1: Assess overseas markets with the greatest potential

Before entering a new market, you should already have researched its suitability through traditional channels.

Complement that knowledge with the information an SEO specialist’s experience and tools can provide about how, how often and when people search in each market.

Also investigate the competitors you will encounter in search results, who may differ from the brands you already know.

This analysis helps you prioritise markets with promising demand, make better use of investment and reduce the risk of choosing an unsuitable country or language.

Step 2: Identify important search engines in each country

Google’s broad international reach does not mean every market uses it in the same way. Alternative search engines can matter in particular regions, so consider them and their ranking systems when planning visibility.

For example:

• Russia: Yandex.
• China: Baidu.
• South Korea: Naver.

Make sure you understand how these engines work and their ranking criteria so you can adapt the SEO strategy. Ignoring them could limit visibility in important markets.

Step 3: Choose the right URL structure

Your website’s URL structure can be critical to international strategy. Content needs organising by market, and the structure can affect how you manage and develop local search visibility.

Common options include:

• Country-code domains (ccTLDs): example.fr, example.es or example.mx provide a strong country-targeting signal to Google.
• Subdirectories: example.com/fr/ or example.com/es/. These retain one global domain, simplifying SEO management and consolidating authority. Local targeting still requires appropriate content and signals.
• Subdomains: es.example.com or fr.example.com. These offer some independence between regional versions without registering completely separate domains.

The choice depends on your strategy, resources and objectives. Each option has advantages and drawbacks that need careful assessment.

Step 4: Adapt architecture and content to each country or language

Translating content alone is not enough. Localisation is key to connecting with each market. Adapt text, images and website design to relevant cultural and linguistic differences.

• Culture and behaviour: What works in one market may not resonate in another. Is your brand’s tone appropriate for each country?
• Content architecture: Organise the website so local users can quickly find what they need, reflecting their habits and expectations.

Good content localisation can improve both the user experience and SEO, increasing relevance to local searches.

Step 5: Consider local laws affecting your website

Alongside the legal requirements you should have studied before choosing a market, each country may have specific rules affecting how you structure and operate the website.

Compliance with applicable local requirements matters for avoiding penalties and protecting your brand.

• Privacy and data protection: Consider applicable rules, such as the GDPR in Europe and Brazil’s General Data Protection Law (LGPD).
• Cookies and tracking: Make sure cookie notices and consent mechanisms meet applicable local requirements.

Alongside meeting legal obligations, compliance can help build user trust and support conversions in local markets.

Step 6: Help your content reach the intended market

A sound structure and localised content do not guarantee that search engines will show the intended market version. Additional technical work matters here.

For example:

• Hreflang annotations (article in Spanish): These identify the language and regional alternatives to a page, helping Google serve an appropriate version. For example, they can help distinguish English content for India from an Australian version.
• Local backlinks: Relevant links from websites in the target market can support authority and provide contextual signals about regional relevance.

These measures help search engines select content for the intended audience, supporting conversion opportunities. They do not guarantee exactly who will see a page.

Step 7: Measure and improve continuously

International SEO is no more a “set and forget” activity than domestic or local SEO.

Remaining competitive requires ongoing monitoring, measurement and improvement.

• Analyse metrics: Track page performance in each country and relevant search engine.
• Adjust the strategy: If a market performs differently from expectations, test and refine your approach.
• Technical SEO: Audit regularly for potential crawling, indexing or loading performance issues across countries.

The ability to adapt promptly to market conditions can help maintain and increase visibility.

Bonus: Establish your position, then expand gradually

Would you sell something in France before it has demonstrated traction in Spain?

As a general approach, expanding without validating the offering can be risky through traditional channels and through Google alike.

Instead, develop your existing market, building authority, brand recognition and traffic, then test another market once that work is established.

The experience gained can give you a stronger starting point in the next country.

As the saying goes, do not spread yourself too thin.

The challenges of international B2B SEO

International expansion requires more than a translated website. Challenges include adapting SEO to each country’s cultural, linguistic and legal context, supported by the right technical setup.

Without international expertise, mistakes can follow (article in Spanish).

An effective strategy needs to address obstacles such as:

1. Adapting to cultural and linguistic differences

Translated content is not always enough to connect with an international audience.

Cultural details, including idioms, design preferences and local sensitivities, can change how the same message works in each market.

Example: A call to action that works in Spain may need a different level of formality in a Japanese context. Audience expectations should be checked rather than assumed.

2. Local search engines

Although Google has broad global reach, engines such as Baidu in China, Yandex in Russia and Naver in South Korea can be important. Each has its own systems and technical requirements to consider in your strategy.

3. Compliance with legal requirements

Privacy and data protection requirements vary between regions. From the GDPR in Europe to local requirements in countries such as Brazil, compliance protects the business and can strengthen user trust.

4. Choosing the right domain structure

The domain setup, whether country-code domains, subdirectories or subdomains, affects SEO management and user experience. Poor implementation can hinder indexing or confuse search engines.

5. Local competition and market analysis

Identifying competitors and understanding their strategies is essential to standing out. In international markets, search competitors may differ from offline competitors.

6. Coordinating complex technical work

Geographical content targeting (article in Spanish) requires care. From using hreflang to identify regional and language alternatives, alongside suitable canonicalisation for duplicate URLs, to handling geographical redirects without harming indexing, international SEO requires close attention to detail and experience.

7. Creating quality localised content

Content needs to be relevant and engaging for the local audience, because markets differ in many ways.

This involves more than translation: it requires comprehensive website localisation (resource in Spanish) that considers each market’s particular interests and needs.

8. Finding SEO specialists who understand international work

International SEO differs from domestic SEO. The fundamentals are similar, but addressing these challenges and pursuing a project’s objectives requires additional expertise.

And not everyone has it, even if they do not admit it.

Nobody can specialise in everything.

A proven professional or international SEO agency can help a business pursue greater visibility and commercial opportunities on Google in its target markets.
