GUIDE · PART OF ENTERPRISE SEO MANAGEMENT
International SEO:
one brand, many markets.
Selling in several countries means running several versions of your site, and telling search engines which one is for whom. Get that wrong and your German page ranks in Austria, your UK prices show in Australia, and each market competes with the others. This guide covers the structure, the tags and the research that keep markets apart.
What is international SEO?
International SEO is the work of making a site findable in more than one country or language. It has three parts. The first is structure: how the versions of the site are arranged in URLs. The second is signalling: telling search engines which version is meant for which audience, mainly through hreflang tags. The third is research: finding out how people in each market search, because a translated keyword is often the wrong one.
Key facts
- It has three parts: URL structure, signals such as hreflang, and research for each market
- There are three common URL structures: a domain per country, subfolders, and subdomains
- Hreflang tells search engines which language and region each version of a page is for
- Every hreflang tag needs a return tag on the page it points to, or it may be ignored
- People in different markets search differently, even in the same language
- In SEORCE each country or market is added as its own project, with its own tracking

Your own sites end up competing.
The usual sign of a problem is one market's page ranking in another. Search engines have several near-identical versions and nothing clear telling them which is which.
The same page, five times
A UK page and a US page with a few spellings changed look almost identical to a crawler.
Hreflang is easy to break
One missing return tag, or a wrong country code, and the whole set can be ignored.
The words are right and nobody searches them
A literal translation of your best keyword may have no volume in the new market at all.
Structure, signals, and research for each market.
Decide the structure once, because it's painful to change. The other two need attention every time you add a market.
Pick how your markets are arranged.
There's no single right answer. Each option trades effort against how strongly it signals a country.
- A domain for each countryThe strongest country signal, and the most to maintain.
- Subfolders on one domainEverything shares the main domain's authority. The usual choice.
- SubdomainsA middle route, often chosen for technical reasons.
Tell search engines which page is for whom.
Hreflang is the main tool, and the one most often wrong. Each version of a page lists all the others, itself included.
- A tag for each language and regionSuch as en-gb for English in the UK.
- Return tagsIf the UK page points to the German one, the German one must point back.
- A defaultx-default names the page for anyone who matches none of the others.
- No forced redirectsSending visitors to a version by their location can stop crawlers seeing the rest.
<link rel="alternate" hreflang="en-gb"
href="https://ledgerly.com/uk/" />
<link rel="alternate" hreflang="de-de"
href="https://ledgerly.com/de/" />
<link rel="alternate" hreflang="x-default"
href="https://ledgerly.com/" />Find out how each market searches.
This is the part that gets skipped. The site is translated, the keywords are translated with it, and the new market never finds the pages.
- Search volume by countryThe same term can be busy in one market and dead in another.
- Local wordingPeople use different words for the same thing, even within one language.
- Who ranks thereYour competitors in a new market may be companies you've never heard of.
- What AI says thereEngines answer differently by language and country, so track prompts for each market.
Adding a market, in the right order.
Most of the trouble comes from doing step four before step one.
Choose the structure
Subfolders, country domains or subdomains. Decide once, and use it for every market.
Research the market
Search volume, local wording and who ranks, before any page is written.
Search volume and trends →Localise the pages
Prices, examples, spelling and the keywords you found. A straight translation is the minimum.
Add hreflang, with return tags
On every version of every page, then test it.
Free hreflang generator →Track the market by itself
Its own rankings, its own AI prompts, its own baseline.
Enterprise SEO management guide →Build and check a set of hreflang tags.
Hreflang is where most international setups go wrong, and it's quick to get right. Enter the URL for each market and the tool builds the tags, checks the language and country codes, and confirms every version links back to the others.
Three structures, compared.
| Structure | Example | Good for | Watch out for |
|---|---|---|---|
| Country domain | ledgerly.de | A strong local presence, and markets run as separate businesses. | Each domain builds its authority from scratch. |
| Subfolder | ledgerly.com/de/ | Most companies. One domain to maintain, and shared authority. | Needs hreflang done properly to keep markets apart. |
| Subdomain | de.ledgerly.com | Markets hosted or run on different platforms. | Search engines may treat it as a separate site. |
A project for each market, on the same tools.
In SEORCE you add each country or market as its own project. Each one has its own rankings, its own AI prompts and its own crawl, so a market's numbers aren't blended with the others. Keyword Explorer shows search volume by country, and pricing is per project, never per seat.
Frequently asked questions.
International SEO is the work of making a site findable in more than one country or language. It covers how the versions are arranged in URLs, how search engines are told which is for whom, and how each market is researched.
Subfolders suit most companies, because everything shares one domain's authority and there's less to maintain. Country domains send the strongest local signal and take the most work.
Hreflang is a tag that tells search engines which language and region a version of a page is meant for. Each version lists all the others, and each needs a matching tag pointing back.
Yes, if you have separate pages for them. A UK page and a US page in English are near-duplicates, and hreflang is how you tell a search engine which to show where.
It's better not to force it. Automatic redirects by location can stop crawlers from reaching your other versions. Offer the visitor a choice instead.
Add each country or market as its own project. Each project has its own tracking, baseline and reports, and pricing is per project.
Yes. The SEORCE hreflang generator and validator builds a page's language and region tags and checks the codes and return links. It's free and needs no account.
Start with one market, then add the next.
Add your first market as a project and record its baseline. Each further country is one more project, on the same tools.
