What does an international SEO agency do?

An international SEO agency helps a business win organic search traffic and revenue in more than one country or language. That covers market sizing, site structure and hreflang, local keyword research, localised content, international technical SEO and building authority in each market.

Should we use country domains, subdomains or subfolders?

It depends on your markets, your brand and your resources. Subfolders on one domain are usually the simplest to manage and build authority fastest; separate country domains can make sense where local trust or legal requirements matter. We recommend a structure based on your plans for each market, not a single rule.

What is hreflang and why does it matter?

Hreflang is a signal that tells search engines which version of a page is meant for which language or country. Without it, or with errors in it, the wrong country’s page often ranks, and visitors land on the wrong prices, currency or delivery information.

Is translating our site enough for international SEO?

Rarely. People in different countries search for the same product with different words, and sometimes for different reasons. Keyword research in each market shows what customers actually type, so localised pages can target it.

Which markets do you work in?

We run search campaigns across the UK and US, and support brands selling into other English-speaking and European markets. Talk to us about your target countries and we will tell you honestly where we can help.

International SEO Agency For Growth In New Markets

Expanding into a new country is expensive, and paid media is the most expensive way to build demand there. We help brands win organic revenue market by market, from sizing the opportunity before you invest to making sure the right page ranks in the right country.

We’ve Helped Dozens Of Great Brands Grow Their Digital Presence Via Search Marketing

The right page, in the right country, in the right language.

International sites lose revenue in quiet ways: the UK page ranking in the US, two country sites competing for the same searches, translated pages that miss how local customers actually search, or hreflang errors that leave whole markets invisible.

We fix the structure first, then build visibility and authority in each market, with reporting that shows organic revenue by country so you can see which markets are paying back.

What International SEO Delivers For The Business

The aim is a lower cost of entering each new market, and organic revenue that keeps growing once you are there.

Lower Cost Of Market Entry

Organic visibility builds demand in a new country without paying for every visit.

Investment Where It Pays Back

Markets prioritised by organic opportunity, so expansion budget goes to the countries most likely to return it.

No More Markets Competing

Each country’s page ranks in its own market, instead of country sites taking each other’s traffic.

Pages Customers Recognise

Content built around local search terms and expectations, which ranks and converts better than translation alone.
