Expanding an ecommerce site into new countries or languages creates a specific set of SEO decisions that don't come up on a single-market site: which URL structure to use, how to signal language and country targeting to search engines, and how to avoid the site competing against itself in search results across markets. Getting these decisions wrong early is expensive to fix later, since it usually means restructuring URLs across the entire international footprint.
Choosing a URL Structure
There are three common approaches, and none is universally "best." The right choice depends on resourcing, existing domain authority, and how distinct the markets need to be from each other.
| Structure | Example | Strengths | Trade-offs |
|---|---|---|---|
| ccTLD (country-code domain) | example.fr, example.de | Clearest country signal to both users and search engines; can build independent domain authority per market | Most expensive and slowest to set up; SEO authority doesn't automatically transfer between domains |
| Subdirectory | example.com/fr/, example.com/de/ | Consolidates all authority under one domain; fastest and cheapest to launch new markets | Country signal relies more heavily on hreflang and content signals rather than the URL itself |
| Subdomain | fr.example.com, de.example.com | Some separation for market-specific hosting or teams | Historically treated similarly to a separate site by some search engines, similar downside to ccTLDs without the clear country signal benefit |
For most growing ecommerce businesses without the resourcing to manage several fully independent domains, subdirectories are the most practical starting structure, since they consolidate SEO authority in one place while still allowing market-specific content and hreflang targeting.
Hreflang: Telling Search Engines Which Version to Show Whom
Hreflang tags tell search engines which language and, optionally, country version of a page is intended for which audience, so that a French speaker in Canada is shown the French-Canadian version rather than the French-France version, where both exist. Getting hreflang wrong (missing reciprocal tags, incorrect language or country codes, or tags that point to non-existent or redirecting URLs) is extremely common and often invisible without a dedicated audit, since the site still functions normally for a user browsing it directly.
Every page in a hreflang set needs to reference every other version, including itself (a self-referencing hreflang tag), and all references need to be reciprocal: if the English page points to the French page, the French page needs to point back to the English one. A single broken link in that chain can cause search engines to disregard the whole set for that page.
Avoiding Duplicate Content Across Markets
Markets that share a language, most commonly UK and US English, create a specific duplicate content risk if product content is simply copied across both without adaptation. Beyond the obvious (currency, spelling conventions, measurement units), genuinely differentiating the content for each market, local shipping information, region-specific compliance details, locally relevant use cases, helps search engines treat each version as a distinct, purposeful page rather than a near-copy.
Country Targeting Without Search Console's Old Tool
Google Search Console previously offered a manual international targeting setting that let site owners specify a target country for generic (non-ccTLD) domains. That feature was retired, which means for subdirectory or subdomain structures, geotargeting today relies more heavily on ccTLD choice where used, hreflang implementation, server or CDN location, and on-page signals like currency, local contact details, and locally relevant content, rather than a single explicit setting.
Other Search Engines Worth Considering
Google dominates most Western markets, but expansion into certain regions makes other search engines genuinely relevant: Baidu in mainland China and Yandex in Russia both have meaningfully different ranking factors and technical requirements from Google, and treating them as an afterthought within a Google-first strategy usually produces poor results in those specific markets. This is a specialist consideration outside the scope of most standard ecommerce SEO work and worth flagging honestly rather than assuming standard practice transfers directly.
