International SEO and hreflang without the headaches
Domain structure, hreflang implementation, currency and content localisation for brands expanding from India into the US, UK, UAE and Europe.
Quick answer
For international SEO, choose subdirectories over ccTLDs unless you have local entities, implement bidirectional hreflang with self-referencing tags and an x-default, localise currency, spelling and examples rather than translating literally, and build local links in each target market.
Choosing a structure
| Structure | Pros | Cons |
|---|---|---|
| example.com/uk/ | Consolidated authority, cheapest to run | Weaker local signal than a ccTLD |
| uk.example.com | Clear separation, flexible hosting | Authority splits across subdomains |
| example.co.uk | Strongest local trust signal | Expensive, slow to build authority per domain |
Hreflang rules that prevent errors
Get these right
- Every page references itself plus every alternate — links must be bidirectional
- Use language-region codes correctly: en-GB, en-AE, en-US, not uk or uae
- Include an x-default for the global or language-selector page
- Keep canonical tags self-referencing; never canonicalise across locales
- Deliver hreflang consistently in HTML head or XML sitemap, not both partially
Localisation beyond translation
What to adapt
- Currency, tax display and payment methods buyers expect locally
- Spelling and idiom — optimise, optimise vs optimize matters for query match
- Local proof: case studies, testimonials and phone numbers from that market
- Search behaviour: UAE audiences often search in English with Arabic brand terms
