International SEO

When you need international SEO

• You sell products or services in more than one country.
• You publish content in more than one language.
• You want different prices, currencies, delivery options or content for different regions, even in the same language, such as the UK and the US.

Choosing a site structure

There are three main options, each with pros and cons:

• Country-code top-level domains (ccTLDs), such as yourbrand.de and yourbrand.fr. They send the strongest country signal and build local trust, but each domain must build its own authority and they cost more to manage.
• Subfolders, such as yourbrand.com/de/ and yourbrand.com/fr/. Authority is shared across the whole domain, and management is simpler. This is often the best choice for most businesses.
• Subdomains, such as de.yourbrand.com. Easier to host separately, but they may not benefit as fully from the main domain’s authority.

Avoid relying on URL parameters (such as ?lang=de) or automatic IP-based redirects alone.

Hreflang tags

Hreflang tells Google which language and region each page targets and links equivalent pages together. It prevents the wrong version from appearing in a market and helps Google understand that similar pages in the same language are regional variants rather than Duplicate Content.

Localise, do not just translate

Successful international SEO goes beyond translation:

• Do keyword research for each market (Keyword Research); people in different countries use different terms, even in the same language.
• Adapt content to local culture, examples, units, currencies, regulations and spelling.
• Use native speakers to write or review content.
• Localise metadata, URLs where appropriate, images and structured data.
• Show local contact details, prices and delivery information.

Avoid forced redirects

Automatically redirecting users based on IP address can stop Googlebot, which mostly crawls from the US, seeing other versions. Instead, suggest the local version with a banner and let users choose, and ensure every version is crawlable.

Building authority in each market

Earn links and mentions from sites in each target country, list your business in local directories and consider local Digital PR. A site with no links from a country will find it harder to rank there.

Measuring international performance

In Google Search Console, filter by country to see impressions, clicks and positions in each market, and check which URLs rank in each country. Use rank tracking set to each target location and language.

Common international SEO mistakes

• Missing or broken hreflang return tags.
• Machine-translated content with no review.
• One English site trying to rank in every English-speaking country without regional differences.
• Mixing languages on the same page.
• Canonical tags pointing all language versions to one URL.

For businesses expanding abroad, planning the structure before launching new markets avoids costly migrations later.

Key Takeaways

• International SEO shows the right version of your site in each country and language.
• Subfolders are often the most practical structure.
• Hreflang links equivalent pages and prevents the wrong version ranking.
• Localise content and keywords; do not just translate.
• Avoid forced IP-based redirects.
