What we do
Everything a website needs to rank in several countries
Structure per market
We decide with data whether each country gets its own domain, a subdomain or a folder, based on the authority you already have and the budget per market. If it has to change, we migrate without losing traffic.
Hreflang and language versions
We implement and monitor hreflang, canonicals and language redirects, which break silently with every release. No IP-based redirects that hide versions from Google.
Keyword research in every country
Keywords, intent and competitors of each market, not a translation of the Spanish research. Mexican Spanish is not searched like Spain's, and British English is not American.
Localised content, not translated
Categories, product pages and content in each market's own terms, at scale and reviewed by a person before publishing.
Links and mentions in every country
An authority plan with media from the market you want to rank in. More on link building and digital PR.
AI visibility per language
We track which brands ChatGPT and Google AI recommend in each language and which sources they cite. Our GEO service, market by market.
How we work
- 1
International SEO audit
Structure, hreflang, indexing per country, duplicate content across languages and the authority of each version, ranked by the traffic each issue costs.
- 2
Choosing markets
Demand, competition and margin per country, to decide where to start. Two markets done well beat six done halfway.
- 3
Strategy per country
Keywords, architecture and goals for each market, from its own starting point.
- 4
Execution
Technical work, content and links for every market, with one team and one calendar.
- 5
Report per market
Every month, sales, leads, visibility and AI answers per country. A global average hides the market that is not working.

FAQ
International SEO FAQ
-
It ranks a website in several countries and languages: it decides the domain or folder structure, implements hreflang, researches each market's searches, localises the content and earns links from media in each country. And it measures every market separately.
-
The team works in Spanish and English. For other markets we research demand in each country's language and have the content reviewed by native speakers before publishing.
-
Folders add up the authority of a single domain and are usually the most efficient way to start. A domain per country sends a stronger local signal, but each one starts from zero. We decide in the audit with the authority, demand and budget of each market.
-
No. A translated website keeps the keywords of the original research, and each country searches with other words. You need keyword research in every language and localised content.
