Search localization covers how search engines adapt results to where a searcher is and what language they use, and how websites tell engines which country and language each page is for. A query like “payroll software” returns different results in the US, UK and Germany because laws, providers and language differ. Sites targeting several markets use localized pages, hreflang and clear URL structures to help engines serve the right version.
How engines localize
Google uses the searcher's location and language settings to adjust results. For a long time Google also used country domains like google.co.uk, but in 2025 it began redirecting those domains to google.com, saying it already localizes results regardless of domain. Local relevance now depends on the searcher's context rather than the domain they visit.
How sites signal their audiences
Google's documentation on multi-regional sites describes the main options.
- Country-code domains, such as example.de
- Subfolders, such as example.com/de/
- Subdomains, such as de.example.com
- hreflang annotations linking language and region versions
- Local content: currency, legal references, examples and contact details
Testing localized results
To see results for another market, use a rank tracker that queries from that location, or adjust location settings carefully. Results URL parameters such as gl for country and hl for interface language can approximate what users see, though they are not perfect simulations.

Separating US and UK pages
Hypothetical payroll platform Paybrindle serves the US and UK from one set of pages, and the UK pages rank poorly. The team creates /uk/ pages that use UK tax terms, pound pricing and local compliance details, adds hreflang between the versions, and measures the UK performance by country in Search Console.
Common mistakes
Translating without localizing
A translated page that keeps US examples and pricing does not serve another market well.
Redirecting users by IP only
Forced IP redirects can stop crawlers, which mostly crawl from the US, seeing other versions. Offer a choice instead.
Questions
No. Subfolders with hreflang and localized content can work well. Country domains send a stronger country signal but are more work to build authority for.
