How to Do International SEO in 2026: A Step-by-Step Guide

Are you planning to expand your business into new countries and want customers to find you through Google and other search engines? Then you need to consider how your website is structured, how your content is translated, and how well that content matches the needs of each local market. This is where international SEO comes in.

Google needs to understand which language or country each page is intended for. This helps the search engine determine which version of your website is most relevant to a particular user.

But international SEO involves more than technical configuration. A keyword that attracts plenty of searches in the United States might be far less popular in the United Kingdom. And even if you've translated every page correctly, that doesn't mean your website will automatically perform well in another country.

In this guide, I'll explain how to do international SEO in 2026, covering international keyword research, URL structures, hreflang, content localization, and the technical challenges you need to consider when expanding into new markets.

What is international SEO?

International SEO is the process of optimizing your website to reach people in different countries or language markets. When implemented correctly, it helps search engines identify and display the most relevant version of your content for users in each market.

There are two main types of international SEO:

• Multilingual SEO: Optimizing your website for people who speak different languages. For example, you might offer English, Spanish, and French versions of the same website.
• Multiregional SEO: Targeting users in different countries or regions. For example, you might have separate English-language pages for customers in the United States and the United Kingdom.

Google also makes this distinction in its official documentation for international websites. The two approaches can overlap, but they don't have to.

For example, an American online store that also ships to Australia doesn't automatically need an entirely separate Australian website. Its existing English-language product pages might already meet the needs of Australian customers.

However, if Australians use different search terms, expect prices in Australian dollars, or need different product information, creating localized Australian pages may be worthwhile.

When do you need international SEO?

Not every website that receives international visitors needs a dedicated international SEO strategy.

Imagine you run a consulting business in the United States and regularly receive visitors from the United Kingdom. If those visitors are looking for the same services and your existing pages answer their questions, you don't necessarily need to build a separate UK website.

That changes when you actively want to enter new markets. International SEO becomes particularly relevant when you:

• Sell products or services in multiple countries.
• Want to reach customers who search in different languages.
• Notice that your existing content doesn't match local search behavior.
• Offer different prices, products, or services depending on the country.
• Manage a website with separate language or country versions.

My advice: Don't start by translating your entire website. First, investigate whether there's enough demand in the market you want to enter. Otherwise, you could spend considerable time and money developing pages that attract very little relevant traffic.

Step 1: Research which international markets offer the best opportunities

Before creating translated or localized pages, you need to understand which countries offer realistic opportunities for your business.

Start with the data you already have. In Google Search Console, you can see which countries generate impressions and clicks for your website. In Google Analytics 4 (GA4), you can investigate where visitors come from and which countries generate inquiries, purchases, or other conversions.

This is a useful starting point, but it's not enough to determine where you should expand. Research the following for each potential market:

1. Search volume: How many people search for your products or services?
2. Competition: Which websites dominate the local search results?
3. Search intent: Are people looking for information, comparisons, or businesses they can buy from?
4. Commercial opportunities: Can you actually serve customers in this market?
5. Required investment: How much work will it take to develop relevant content and a suitable website?

You can use tools such as Semrush to research keywords, competitors, and estimated search demand in different countries.

A country with a large search volume isn't automatically the best opportunity. If competition is particularly strong or your services don't match local expectations, a smaller market might be more attractive.

Look beyond search volume

Imagine you run a software company and want to expand into the United States and Australia.

The total search volume for your main topics might be considerably higher in the US. However, if the search results are dominated by established software companies with extensive content libraries, building visibility could be difficult.

Australia might have lower search volume, but the competition and investment required to compete could be more manageable.

You therefore need to consider more than how much traffic a market could generate. You also need to understand how difficult it will be to attract that traffic and what those visitors could be worth to your business.

Step 2: Conduct international keyword research

One of the most common mistakes in international SEO is simply translating existing keywords. A translated term might be grammatically correct but rarely used by people searching in the target market.

This can happen even when two countries speak the same language. For example, Americans commonly search for apartments for rent, while people in the UK are more likely to use flats to rent.

Another example is vacation accommodation. Americans often search for vacation rentals, while British users may search for holiday cottages or holiday lets, depending on the type of property.

The underlying need may be similar, but the language people use to express it can be quite different.

How to do international keyword research

Here's how I would approach it:

1. Start with the topic, not the keyword. Identify the purpose of the original page. Is it intended to answer a question, help users compare options, or encourage a purchase?
2. Research local search terms. Use a keyword research tool such as Semrush and select the specific country you want to target. Don't assume that the highest-volume keyword in your home market is also the best keyword elsewhere.
3. Examine the local search results. Which types of pages rank for your target keywords? Are they product pages, comparison articles, informational guides, or local service providers? This tells you what Google currently considers relevant to users in that market.
4. Check search intent. A similar keyword can have a different meaning or search intent in another country. For example, a term might predominantly return informational articles in one market but commercial service pages in another.
5. Create a separate keyword map for each market. Assign your chosen keywords to the pages you plan to create or adapt.

Your research might show that you need a different content structure for certain countries. That's perfectly fine. The goal isn't to make every language or regional version identical. It's to satisfy the search intent of users in each market.

Step 3: Choose the right international URL structure

Once you know which countries and languages you want to target, you need to decide how to organize your website. There are three commonly used approaches.

Google supports these approaches and discusses their advantages and disadvantages in its documentation on managing multiregional websites.

Which URL structure do I recommend?

In my experience, the right choice depends heavily on your existing domain. If you already have a generic domain such as .com, subdirectories are often a practical way to target multiple countries. For example:

• example.com/us/ for the United States.
• example.com/uk/ for the United Kingdom.
• example.com/au/ for Australia.

You can manage these pages under one domain and build on your existing internal linking structure and SEO signals.

But what if you already have a country-specific domain? Then the decision is different. For example, Google recognizes .co.uk as a strong geographic signal that a website targets the United Kingdom.

You could still publish Australian content under example.co.uk/au/, but a separate .com.au domain might be more appropriate if you're specifically targeting Australia.

If you're planning to expand into several countries, a generic domain such as .com with regional subdirectories could be a better long-term solution. However, migrating an established website to a new domain introduces SEO risks. If your existing .co.uk website already performs well, I wouldn't recommend moving it without carefully evaluating the potential impact.

Your company's structure also matters. Do you have independent regional offices with different product ranges, technical systems, and marketing teams? In that case, separate country domains or subdomains might make more sense.

There isn't one URL structure that's always best for international SEO. The right choice depends on your existing domain, target markets, and plans for international growth.

Step 4: Use hreflang to identify language and regional versions

When your website has multiple language or regional versions, you want Google to understand which page is intended for which audience. This is where hreflang comes in.

Hreflang tells Google which pages are alternative language or regional versions of one another. For example, it can help Google select the US version of a page for someone searching in the United States and the UK version for someone searching in the United Kingdom.

Imagine your website has two versions of the same services page:

• United States: https://example.com/us/services/
• United Kingdom: https://example.com/uk/services/

You can use hreflang to tell Google that these pages belong together. One way to do this is by adding the following code to your website:

<link rel="alternate"
      hreflang="en-US"
      href="https://example.com/us/services/" />

<link rel="alternate"
      hreflang="en-GB"
      href="https://example.com/uk/services/" />

In this example, en-US means English for the United States and en-GB means English for the United Kingdom. You can also use en-AU for English in Australia or a language-only code such as es for Spanish without specifying a country.

These references need to appear on both pages. The US page must reference the UK version and itself. The UK page must contain the same two references. This helps Google understand that the pages are related and intended for different audiences.

Important: Hreflang helps Google select the appropriate language or regional version, but it doesn't guarantee that Google will display that version. It also isn't a direct ranking factor that automatically improves your positions.

How can you implement hreflang?

You don't necessarily have to add the code manually. There are several ways to implement hreflang.

1. Using a WordPress plugin. If your website runs on WordPress, a multilingual plugin is often the easiest solution. Plugins such as WPML and Polylang can connect different language versions of your pages and automatically generate the appropriate hreflang tags. For example, you can specify which English page corresponds to a Spanish or French version. The plugin then handles the technical references. However, you should still check whether everything is configured correctly, particularly when pages are missing, deleted, or unavailable in certain languages.

2. Adding hreflang to your HTML. You can also add hreflang directly to your website's HTML code. These references appear in the <head> section of each page. This gives you complete control, but maintaining the tags can become time-consuming on larger websites. Whenever you add, remove, or change a page's URL, you may also need to update its hreflang references.

3. Using an XML sitemap. Another option is to include hreflang information in your XML sitemap. A sitemap is a file that helps search engines discover important URLs on your website. You can also use it to specify which pages are alternative language or regional versions of one another. This can be particularly useful for larger international websites because you don't need to add hreflang tags individually to the HTML of every page.

4. Using HTTP headers. Hreflang can also be implemented through information sent by your web server. This approach is particularly useful for files that aren't standard HTML pages, such as PDF documents available in multiple languages. Most WordPress websites won't need this method.

You don't need to use all of these implementation methods simultaneously. One correctly maintained method is sufficient. Want to create the tags without writing them by hand? Use my free hreflang generator for HTML tags, an XML sitemap or HTTP headers.

Common hreflang mistakes

When conducting an international SEO audit, I would check for the following issues:

• Missing reciprocal references between pages.
• Invalid language or country codes.
• References pointing to pages that no longer exist.
• Hreflang references pointing to non-indexable URLs.
• Conflicts between hreflang and canonical tags.
• Missing or incorrect connections between equivalent pages.

Tools such as Screaming Frog can help identify these problems across a whole site. To check a single page and its language versions right away, you can use my free hreflang checker. Google also provides detailed instructions in its official hreflang documentation.

Step 5: Make sure Google can crawl and index your international pages

A good URL structure and correctly configured hreflang tags are important, but Google also needs to be able to discover and index your international pages. This means Google must be able to access your pages, read their content, and consider them for inclusion in search results.

One problem I regularly encounter is websites automatically redirecting visitors to a different regional version based on their location.

Imagine someone in Australia wants to visit the UK version of your website at example.com/uk/. Your website detects that the visitor is in Australia and automatically redirects them to example.com/au/.

That might seem helpful, but it can create problems. Not everyone in Australia wants to view the Australian version of your website. Someone might be researching a product available in the UK or comparing prices between markets.

Automatic redirects can also cause problems for search engines. Google uses a crawler called Googlebot to discover and access websites. Googlebot generally crawls from the United States, and its regular crawls don't send an Accept-Language header. If your website automatically redirects visitors based on their location or language settings, Googlebot may have difficulty accessing certain regional versions.

A better solution is to let visitors choose their preferred version. For example, you can add a country or language selector and optionally display a message informing visitors that another regional version is available. This keeps your different versions accessible to both users and search engines.

Be careful with canonical tags

A canonical tag is a piece of code that tells Google which URL you consider the preferred version when multiple pages contain identical or very similar content. On international websites, it's important to configure these tags carefully. Otherwise, Google may decide not to index certain language or regional pages separately.

Imagine you have two versions of the same services page:

• example.com/us/services/
• example.com/uk/services/

Both pages target different audiences, and you may want Google to index and display them separately. If you set the canonical tag on the UK page to point to the US page, you're telling Google that the US URL is your preferred version. This could result in Google choosing not to index the UK page separately.

For distinct, indexable language or regional pages, using a canonical tag pointing to the page's own URL is often appropriate.

The situation becomes more complicated when you have several pages in the same language with almost identical content. For example, your US and UK pages might differ only in pricing, spelling, or a few regional details. In those cases, you need to consider carefully which URL Google should treat as the preferred version and how hreflang fits into that decision.

The most important thing is to make sure your canonical configuration doesn't unintentionally prevent Google from indexing the international pages you want to appear in search results.

Step 6: Localize your content instead of just translating it

You've identified the right keywords, selected an appropriate website structure, and configured the technical signals. Now you need to make sure your content actually meets the expectations of your target market.

There's an important difference between translation and localization. Translation converts existing content from one language into another. Localization adapts the content to the needs, expectations, and circumstances of a specific audience. That might involve:

• Using keywords and terminology commonly used in the target country.
• Including different examples and case studies.
• Discussing relevant local laws or regulations.
• Displaying prices in the appropriate currency.
• Adjusting products or services for the local market.
• Featuring reviews and testimonials relevant to that audience.

Even when two countries share the same language, localization can be important. For example, a US ecommerce website expanding into Australia may need to adjust product terminology, shipping information, measurements, currency, and references to local regulations. Simply changing American spelling to Australian spelling won't necessarily be enough.

Can AI handle the translation?

AI can significantly speed up translation work in 2026. For relatively straightforward content, the quality can be quite good. But that doesn't mean every AI-generated translation is ready to publish.

An AI model might produce grammatically correct text without fully understanding local search intent, terminology, or commercial context.

My advice is to use AI as a tool, but have important commercial pages reviewed by someone who understands both the language and the local market. For example, if you're expanding into the UK, your content should do more than use correct British English. It should reflect how British customers search for products, compare providers, and make purchasing decisions.

Step 7: Build search visibility in each target market

Publishing new language or regional versions doesn't mean you'll automatically achieve the same visibility as your original website. Your content still needs to compete with websites that may have been established in the target market for years.

Alongside technical implementation, I would focus on the following areas:

• Local competitors: Research which websites rank for your most important keywords and why their pages match local search intent.
• Internal linking: Make sure visitors and search engines can easily navigate between relevant pages within each language or regional version.
• External links and mentions: Links and references from relevant websites in your target market can help strengthen your website's visibility and credibility.
• Local expertise: Publish content demonstrating that you understand the market. This might include local examples, original research, industry data, or practical experience.

You don't necessarily need a completely different link-building strategy for every country. However, you do need to understand which websites are relevant and influential within each market and how competitive the local search results are.

Step 8: Measure international SEO performance by country

Evaluating an international SEO strategy based only on total organic traffic can give you an incomplete picture.

Imagine your website's organic traffic increases by 20%. That sounds positive, but what if the entire increase comes from the United States while your newly launched Australian pages receive almost no impressions? You need to measure performance separately for each target market.

It's also important to distinguish between a visitor's location and the regional version of the page they visit. For example, someone in Australia might land on a US version of your website. That isn't necessarily a problem. But if you've specifically developed Australian content, you'll want to understand why Google isn't showing that version instead.
