DefinitionSEO for websites that target multiple countries or languages: choosing a URL structure, implementing hreflang, localising content and building authority per market.
International SEO is what changes when a site stops targeting one country and starts targeting several. The keyword research, the content and the technical work are all still there, but now they happen per market, and a new layer of decisions appears: which domain or folder each market gets, how Google is told which page belongs where, and how a site with authority in the Netherlands earns any in Germany. The mistake I see most is treating it as a translation project. A Dutch webshop translated into German is not a German webshop until the keywords, prices, delivery promise and links are German too.
Why it matters for cross-border growth
For most Dutch and Belgian webshops, the next growth step is Germany, and Germany is a different search market. Searchers use different words for the same product, expect prices in a particular format, trust different review platforms and buy from shops that look local. A shop that launches a .de with machine-translated category names and Dutch-style payment options gets traffic from nobody. A shop that researches German search terms, writes German category text and shows a German delivery promise can build a second business on the same stock.
I saw this play out with a Dutch webshop expanding to the UK. The English pages went live with translated Dutch product names, and the UK Search Console showed impressions for terms the site had never targeted while the real UK search terms were missing entirely. Rewriting the category pages around British search language, adding UK-specific delivery and returns information and getting a handful of UK links changed the picture within a quarter. The SEO fundamentals did not change; the market did.
How to check how each market is performing
Google Search Console with a Country filter is the starting point. For each target market, look at impressions, clicks and average position, and check which pages and queries appear. If the German market shows the Dutch site’s pages instead of the German ones, there is a hreflang or structure problem. If the German pages appear but for the wrong queries, it is a keyword and content problem. Set up a separate property per domain or folder so the comparison is clean.
In Ahrefs or Semrush, run keyword research per country database rather than translating the Dutch keyword list, and compare organic keywords and referring domains for each market’s site against the local competitors, not against the Dutch ones. A crawl in Screaming Frog with hreflang extraction on shows whether the markets are technically connected. And in GA4, compare conversion rate and revenue per market rather than sessions; a market with half the traffic and twice the conversion rate deserves more attention than the numbers suggest at first glance.
Mistakes I see on international sites
Choosing the URL structure by habit. Country domains, subfolders and subdomains each have trade-offs. Country domains signal locality strongly but start with zero authority. Subfolders share authority but need geotargeting per folder. Subdomains combine the disadvantages of both. Pick deliberately.
Translating instead of localising. The Dutch “tuinset” becomes “Gartenset” in German, but Germans search for “Gartenmöbel Set” or “Sitzgruppe Garten”. The translation is correct and the keyword is wrong.
Automatic redirects based on IP. Googlebot crawls from the US. If every visitor is forced to their country version, Google may never see the German pages. Suggest, do not force.
One link profile, many markets. The Dutch site has 400 referring domains, the German site has 3. Google evaluates the German site against German competitors, and they have more than 3.
Half-translated sites. German product pages with Dutch checkout, English category text with Dutch filters. Every switch in language is a signal to Google and a reason for the visitor to leave.
How I approach international SEO with clients
Before anything is built, I ask which markets are worth targeting and why. That means search demand per country for the core categories, competition in the local results, margins after local shipping and returns, and whether the client can handle customer service in that language. A market that fails on two of those four is not worth an SEO investment yet. For the markets that pass, I write down the URL structure, the hreflang matrix and the geotargeting settings before the first page exists, because changing those later is a migration.
Then the work becomes market-specific: keyword research in the local language with a native speaker checking the intent, category and product content rewritten rather than translated, local trust signals such as reviews, payment methods and delivery terms, and a link building plan per market with its own targets. On platforms like Shopify Markets or PrestaShop multistore, I check the technical edges closely, because products that exist in one market only and categories that are empty in another are where the setup usually breaks. This is what my international SEO service covers end to end, from market choice to the monthly report per country.
Frequently asked questions
Should I use a country domain or a subfolder?
If the brand is strong in one market and you are expanding to two or three more with limited budget, subfolders on the main domain let the new markets borrow authority and get indexed faster. If each market will have its own team, its own marketing and its own trust to build, country domains are cleaner and signal locality more clearly. Many established shops run a mix. The wrong answer is switching structure every few years.
Does the same content in Dutch for NL and BE count as duplicate content?
Not if hreflang connects the two versions and they differ in the details that matter to each country: prices, delivery, contact details, spelling where relevant. Google understands regional variants of the same language. It becomes a problem only when the pages are identical and there is no hreflang, because then Google picks one and the other market loses its visibility.
How long does it take for a new country site to rank?
A subfolder on an established domain can rank for long-tail queries within a couple of months. A fresh country domain typically needs six to twelve months of content and links before it competes for commercial category terms, longer in Germany and the UK where established competitors are strong. The timeline shortens considerably if the launch includes local links and reviews from day one instead of adding them later.
