International SEO: How to Reach Customers in Other Countries

International SEO is the process of improving a website so that people in different countries and language markets can find the most relevant version of its content. It combines technical configuration with locally appropriate content, helping search engines understand which pages to show to which audiences.

Whether you are a small business exploring overseas markets or an established company serving customers worldwide, a clear international SEO strategy can make your website easier to discover and use.

What does international SEO involve?

International SEO is more than translating your existing website. It involves deciding which countries and languages you want to target, creating useful content for those audiences, and signalling your targeting clearly to search engines.

A strong approach considers factors such as local search behaviour, spelling and terminology, currencies, shipping or service availability, and cultural expectations. A page written for English-speaking customers in the UK, for example, may not fully meet the needs of customers in the United States, Australia or Ireland.

Choose the right website structure

Your URL structure helps visitors and search engines understand how your international content is organised. Common options include:

• Country-code top-level domains (ccTLDs): Separate domains for different countries, such as example.fr or example.de. These can provide a clear country signal but may require more time and resources to manage.
• Subdirectories: Country or language folders on one domain, such as example.com/fr/. These are often straightforward to manage and allow pages to share the domain’s authority.
• Subdomains: Separate sections such as fr.example.com. These can be useful in some circumstances, but may need additional configuration and management.

There is no single structure that suits every organisation. Consider your budget, technical setup, branding and long-term plans before choosing. Whichever structure you use, keep it consistent and make it easy for visitors to move between relevant versions.

Use hreflang correctly

The hreflang attribute helps search engines understand the language and, where relevant, the regional audience for a page. It can help them serve the appropriate version when similar pages exist for different markets.

For example, a website might have separate pages for English-speaking users in the UK and the US. Each page should reference the relevant alternatives, including itself, using valid language and region codes. Make sure the references are reciprocal: if one page points to another as an alternative, the other should point back.

Hreflang is not a substitute for good content or a guarantee that a particular page will appear in search results. Incorrect or incomplete implementation can also make the page relationships difficult for search engines to interpret. Check the tags regularly, particularly after website migrations or URL changes.

Research local keywords and search habits

People in different markets may use different words to describe the same product or service. Directly translating a keyword list can miss local expressions, spelling differences and differences in search intent.

Carry out keyword research for each target market. Look at the terms people actually use, the questions they ask and the types of results search engines show. Pay attention to local spelling and vocabulary, such as “trainers” in the UK and “sneakers” in the US, where relevant to your offering.

Use these findings to shape page titles, headings, product descriptions and other on-page content. Avoid inserting keywords unnaturally; the content should still be clear and helpful to the reader.

Localise content, not just language

Translation can be a useful starting point, but effective international content often needs localisation. This means adapting material to the audience’s context while preserving the intended meaning and brand voice.

Depending on the market, localisation may include:

• Using local spelling, terminology, measurements and date formats
• Displaying prices in the appropriate currency, with clear information about taxes
• Explaining delivery, returns, warranties or service coverage for that country
• Adapting examples, images and references to suit local expectations
• Providing accurate contact details and customer support information

Where possible, have content reviewed by someone familiar with the target market. This can help catch awkward phrasing and ensure that the page feels relevant rather than mechanically translated.

Make the site easy to navigate

Visitors should be able to find the version of the site that best suits them. Provide clear language or region options and make sure the selection is easy to change. Avoid automatically redirecting people based only on their IP address: location detection can be unreliable, and visitors may want to view a different version.

Keep navigation, internal links and calls to action appropriate for each market. A translated page that links back to the wrong country’s product range, delivery information or contact page can create a confusing experience.

Consider technical and legal requirements

International pages should be crawlable, indexable and included in the right XML sitemaps. Check that page URLs, canonical tags and hreflang references work together correctly, and avoid accidentally directing search engines away from localised pages.

Also consider local requirements that affect your website, such as privacy notices, consent practices, consumer information and accessibility. Requirements vary between jurisdictions, so seek appropriate legal advice when necessary.

Build visibility in each market

Relevant links and brand mentions can support visibility in international markets. Focus on earning links from reputable, locally relevant websites through useful content, partnerships, industry participation and genuine public relations. Avoid buying links or using automated schemes, which can put a site’s search performance at risk.

Local business listings may also be useful where the organisation has a genuine presence and the listings are relevant to its services. Keep business details accurate and consistent.

Measure results by country and language

International SEO should be monitored separately for each target market. Review organic traffic, search visibility, engagement and conversions by country, language and page. This can reveal whether a page is attracting the right audience and whether visitors are completing meaningful actions.

Use analytics and search performance tools to identify issues such as pages receiving impressions but few clicks, or visitors leaving before reaching key information. Compare performance over time, taking account of seasonality and differences between markets.

Common international SEO mistakes

• Translating pages word for word without local keyword or audience research
• Using hreflang codes incorrectly or failing to link alternate pages back to one another
• Creating country pages with little unique, useful content
• Redirecting visitors automatically without giving them a choice
• Using inconsistent URLs or mixing language and country targeting without a clear plan
• Forgetting to update internal links, canonical tags and sitemaps when pages change

Build a practical international SEO plan

Start by choosing the markets that best match your business goals and capabilities. Research their audiences, search demand and operational requirements before expanding. Then select a manageable URL structure, create genuinely useful localised pages, configure technical signals carefully and track results market by market.

International SEO is an ongoing process. Search behaviour, products and local requirements change, so review your pages regularly and update them when the audience’s needs or your offering changes. A considered approach can help your website reach more relevant customers and provide a better experience wherever they are.

What is international SEO?

International SEO is the process of optimising a website so people in different countries or language markets can find the most relevant version of its content in search results. It involves researching local search habits, creating and adapting content for each audience, and using clear technical signals—such as suitable URL structures and hreflang tags—to help search engines understand which pages are intended for which markets.

How does international SEO differ from local SEO?

International SEO helps a website reach audiences in different countries or language markets, using techniques such as localised content, appropriate domain or URL structures and hreflang tags. Local SEO focuses on visibility in a specific geographic area, often for nearby customers searching for a local business, and may involve optimising a Google Business Profile, local listings and location-based keywords. The two can overlap—for example, a company may target several countries and also optimise for customers in particular cities—but they address different geographic scales and search needs.

How do I choose the right URL structure for an international website?

Choose a URL structure that suits your target markets, budget and ability to manage separate versions of your site. Country-code domains (such as .fr) send a clear country signal but can be more costly to maintain; subdirectories (such as example.com/fr/) are often simpler to manage under one domain; and subdomains (such as fr.example.com) can offer flexibility but may need extra configuration. Whichever option you choose, use it consistently, make each market’s pages easy to find, and configure international signals such as hreflang correctly.

What is hreflang, and how should I use it?

Hreflang is an HTML attribute that tells search engines which language and, where relevant, regional version of a page is intended for a particular audience. Use it when you have similar pages for different languages or regions, adding a hreflang reference to each version—including a reference to itself—and ensuring the pages link back to one another. Use valid language and region codes, such as `en-GB` for British English, and keep the URLs accurate and accessible. Hreflang can help search engines show the most suitable page, but it does not guarantee rankings or replace well-localised content.

Should I translate or localise my website content for each market?

Translation is a good starting point, but localisation usually delivers a more relevant experience for each market. Adapt wording, spelling, keywords, currency, measurements, examples and calls to action to reflect local search habits and customer expectations, rather than translating everything word for word. For important pages, have the content reviewed by someone familiar with the market to ensure it feels natural, accurate and useful.

How do I research keywords for different countries and languages?

Start by researching each target country and language separately, rather than translating your existing keyword list. Use local keyword tools and search engine results to discover the terms people actually use, including regional spelling, synonyms and local expressions. Check search intent, too: the same phrase can mean different things in different markets. Where possible, ask native speakers or local specialists to review your findings, then use the most relevant terms naturally in localised page titles, headings and content.

How can I measure the success of my international SEO strategy?

Measure the success of your international SEO strategy separately for each target country and language. Track organic traffic, search impressions and clicks, keyword rankings, and meaningful conversions such as enquiries or sales. Use analytics and search performance tools to see which localised pages attract the right visitors and where people drop off. Compare results over time, allowing for seasonal differences between markets, and use what you learn to improve content, technical setup and user experience.
