Search & AI · International SEO services
Enter new markets without splitting your authority
Going international multiplies every SEO decision. The wrong domain structure or a careless translation programme can cost years. We help you decide which markets justify investment, how the site should be structured for them, and how content is localised so it reads as native and ranks as intended.

In short
What is international SEO?
International SEO is the practice of structuring and localising a website so that search engines show the right country and language version to the right searcher. It covers which markets to enter, whether each market gets its own domain, subdomain or subfolder, how hreflang annotations connect equivalent pages, and how content is adapted to local search behaviour. It is measured by qualified demand in each market, not by the number of languages published.
The problem
Signs it is time to rethink International SEO.
- 01
The wrong country or language version ranks in the wrong market.
- 02
Translated pages exist but attract no demand.
- 03
Regional teams publish independently with no shared standards.
- 04
Leadership cannot compare organic performance across markets.
Why International SEO matters
Search engines need to be told, precisely, which page is for which country and language. When that signal is wrong or missing, the wrong version ranks, authority is split between duplicates and local competitors win by default.
What is included
What do our International SEO services include?
Market selection, site structure, hreflang and localisation for companies selling across borders. The scope is set by the audit: you get the parts you need, in the order that pays back soonest.
- 01
Market selection
Not every market justifies a localised site. We size search demand in the local language, read who already holds the results, and weigh that against whether you can sell, deliver and support there.
- Local-language demand sizing
- Competitor strength by market
- Legal, payment and delivery readiness
- Entry order and investment level
- Markets to postpone, with reasons
- 02
Domain and URL structure
Country domains, subdomains and subfolders each trade location signal against shared authority and running cost. We model the options against your brand, platform and resources, and recommend one with the reasoning written down.
- ccTLD, subdomain and subfolder modelling
- Language versus country targeting
- URL conventions for each locale
- Migration and redirect planning
- Hosting, CDN and speed by region
- 03
Hreflang and canonical logic
Hreflang fails quietly: one missing return link, or a canonical pointing at another locale, and the wrong version ranks. We specify the annotations, choose where they live and test them across the whole site.
- Hreflang in HTML, HTTP headers or sitemaps
- Reciprocal return links verified
- Self-referencing canonicals per locale
- x-default for unmatched searchers
- Locale selectors instead of forced redirects
- 04
Localisation and local keyword research
People in two countries that share a language often search with different words, expect different proof and buy in different ways. Research is done in the local language by native specialists, and content is adapted to what it finds.
- Keyword research in the local language
- Terminology, spelling and units
- Currency, pricing and payment methods
- Local proof, regulation and examples
- Native review of machine drafts
- 05
Local authority
A site with strong references at home can be unknown in a new country. Coverage and links from publications that matter locally help search engines and buyers accept the site as relevant there.
- Local media and trade publications
- Country-specific stories and data
- Local business listings where relevant
- Regional partners and associations
- Referring domains tracked by country
- 06
Governance and measurement
Regional teams and agencies will change the site. Shared standards keep the structure intact, and a single reporting view lets leadership compare markets on the same terms.
- Standards for regional publishing
- Launch checklist for new locales
- Wrong-version ranking monitoring
- Reporting by country and language
- Search engines beyond Google where relevant
How it works
How does a search engine decide which country version to show?
Search engines combine several signals to match a page to a searcher's language and location. None of them is a switch you can simply set, which is why international sites so often show the wrong version. These are the five stages, in order.
- 1
Crawl
Each locale's URLs must be discovered and fetched. Crawlers often arrive from one country and may not state a language preference.
What we doGive every version its own crawlable URL and avoid redirects based on IP address or browser language.
- 2
Language
The language of a page is read from its visible content, not from code labels alone.
What we doKeep one language per page, including navigation and boilerplate, and remove half-translated templates.
- 3
Grouping
Hreflang annotations, when valid and reciprocal, tell the engine that pages are alternates of one another.
What we doGenerate hreflang from a single source of truth and test that every link is returned.
- 4
Targeting
Location is inferred from signals such as a country domain, hreflang, local links, currency and addresses.
What we doAlign those signals for each market so they all point the same way.
- 5
Serving
In results, the engine shows the version that best fits the searcher's language and location.
What we doMonitor which URL ranks in each country and correct the cases where the wrong one appears.
Process
What does a typical International SEO engagement look like?

Compare
Country domains or subfolders: which structure should you choose?
This is the decision that is hardest to reverse. Subdomains sit between the two and are usually chosen for platform or infrastructure reasons, so the practical choice for most companies is between separate country domains and folders on one domain.
| Country domains (ccTLDs) | Subfolders on one domain | |
|---|---|---|
| Location signal | Strongest, tied to one country | Relies on hreflang and content |
| Authority | Each domain builds its own | Shared across all markets |
| Running cost | Higher: many sites to maintain | Lower: one site, one platform |
| Local trust | Familiar to local buyers | Depends on brand recognition |
| Targeting | A country, not a language | Country or language |
| Best use | Deep commitment to few markets | Many markets, limited resources |
Our viewSubfolders suit most companies because authority and effort are shared, and they are the safer default when resources are limited. Country domains earn their cost where local trust, regulation or a dedicated local team make a separate presence worthwhile.

Questions
International SEO services: frequently asked questions.
Something we have not covered?
Talk to a Growth StrategistWhat is hreflang and do we need it?
Hreflang is an annotation that tells search engines which pages are equivalent versions for different languages or regions. You need it when the same content exists for more than one locale, particularly where versions share a language, such as English pages for the UK, USA and Australia. It prevents the wrong version appearing; it does not raise rankings.
How much does international SEO cost?
Cost depends on the number of markets and languages, the state of the current site structure and how much localisation is needed. Fixing hreflang on one domain is a small project; entering five markets with native content is not. We scope after a growth audit and show which markets the proposal covers and why.
How long does it take to rank in a new country?
Correcting targeting errors on an established site can show within weeks. Building visibility in a market where the brand is unknown usually takes many months, because local relevance and authority have to be earned there. A new country domain generally takes longer than a new subfolder on a domain that already has authority.
Is a subdomain or a subfolder better for international SEO?
A subfolder is usually the simpler choice, because it sits on the main domain and shares its platform and reputation more directly. A subdomain can make sense when a market needs separate hosting, a different platform or a team that runs its own site. Both can rank; the difference is mostly maintenance.
Can we just translate our existing pages?
You can, and it is rarely enough. Direct translation keeps the wording of your home market, while local buyers may use different terms, expect different proof and compare you with different competitors. We start from keyword research in the local language, then adapt pages so they match how that market searches and buys.
Should we redirect visitors automatically by location?
Generally, no. Forced redirects based on IP address or browser language can stop search engine crawlers reaching other versions, and they frustrate travellers and expatriates. A better pattern is to let every version load at its own URL and show a dismissible suggestion to switch, with hreflang doing the work in search results.
Do we need a separate strategy for search engines other than Google?
In some markets, yes. Google leads in most countries, but other engines hold meaningful share in places such as China, Russia and South Korea, and Bing matters for some audiences. Each handles language and location signals somewhat differently, so we check which engines your buyers use before finalising the plan.
What do you need from us to start?
Access to Search Console and analytics, a list of the markets you sell in or plan to enter, and an honest picture of what you can deliver and support in each. Contact with regional teams and whoever manages the CMS helps, because most international fixes depend on templates and publishing workflow.
How do you measure international SEO?
Market by market, on the same measures: whether the correct version ranks, non-brand visibility, qualified traffic, and leads or revenue attributed to that country. Reporting is segmented by country and language so a strong home market cannot hide a weak one. Where CRM data is available, organic demand is tied to pipeline per market.
