How to Choose SEO Multilingual URLs: 5 Things to Consider

When you first start planning for website translation, you probably think about your target markets, selected languages for translation, and the range of content types that need translating. But what about your URL structure? As a foundational element of website translation and global SEO, you’ll want to determine your multilingual URL structure strategy early on in the process.

After all, both users and search engines make assumptions about your website and your brand based on the structure and format of your URLs. And the approach you take will most likely be replicated across all markets, so you need to consider the languages you’re planning to translate into in the short term plus the languages you plan to support in 2 to 3 years’ time.

In the interest of brevity, this article focuses on Google—the preferred search engine for 80% of the globe. For countries where Google is not the preferred search engine—such as China (Baidu), Japan (Yahoo), Korea (Naver), or Russia (Yandex)—ensure your globalisation partner has the expertise to tailor your approach for these search engines so you receive optimal results across all target markets.

Multilingual URL structure formats

There are three commonly used approaches to creating multilingual URL/domain structures:

A fourth approach—using query strings to determine the language and country—is sometimes used (most notably by Booking.com), but not recommended by Google.

I’ll discuss the advantages and disadvantages of ccTLDs, subdomains, and subdirectories approaches based on:

  1. Local brand impact
  2. SEO benefits
  3. Set-up & maintenance
  4. Cost
  5. Hosting and content delivery networks

Let’s start with a quick overview of each approach.

Country-code top-level domains (ccTLD)amazon

These are considered by most to be the best option for localised websites. No other method sends a more powerful message in terms of a local market “presence.” According to Google, a ccTLD provides the strongest signal that a website is targeting a specific country and provides some level of SEO benefit for that market. And research shows that in many countries, users are more likely to make a purchase from a website using the ccTLD.

One drawback: Even if they are available, ccTLDs must be purchased and maintained in each market. The ccTLD approach is the best option when a big company has the resources to invest. Amazon, for example, goes so far as to integrate the country code into their logo for each market.

Subdomainshotels

With a slightly less obvious signal than ccTLDs, subdomains provide a quick and easy solution for targeting a particular country or language, producing a simple and visually appealing URL structure.

The subdomain URL structure isn’t as easily recognisable or trusted by website visitors, but you don´t have to worry about the availability of your domain names.

Subdirectoriessamsung

The most commonly used technique for creating multilingual websites, this approach is the easiest and cheapest to implement. Simply add a language directory to your server and leverage your existing setup and infrastructure.

The downside? Subdirectories don’t convey a strong in-country presence. Unless you already have a strong local brand, the URL does little to increase brand awareness and equity. Companies working with smaller and tighter budgets typically use this technique.

Pros and cons of multilingual URL approaches

Now let’s take a high-level look at the implications of each URL approach for our criteria: local brand relevance, SEO, set-up & maintenance, and cost.

Impact on local brand relevance

ccTLD:

  • Delivers high impact and builds trust

Subdomain:

  • Delivers medium impact and instills some trust

Subdirectory:

  • Delivers little impact or trust unless brand is well known in the market

SEO influence

ccTLD:

  • Indicates to users and search engines that the website is targeted to a specific country
  • Easily tracked in most web analytics tools
  • Each website can be hosted in country to further improve multilingual SEO
  • No benefits from other language sites since each stands alone

Subdomain:

  • Indicates to users that the website is targeted to a specific country; search engines require Search Console geotargeting
  • Easily tracked in most web analytics tools
  • Each website can be hosted in country to further improve SEO
  • Limited benefits passed to each website from the popularity of the root domain

Subdirectory:

  • Indicates little to users about targeting; search engines require Search Console geotargeting
  • Challenging to track in most web analytics tools
  • All sites hosted on the same server, hindering SEO improvements
  • Domain popularity benefits all language sites

Set-up & maintenance effects

ccTLD:

  • Complicated to deploy
  • Requires that all domains are available
  • May require a different registration process in each country and individual set-up and maintenance of each site

Subdomain:

  • Relatively easy to deploy Search Console geotargeting

Subdirectory:

  • Easiest to deploy
  • Limited additional setup or maintenance fees
  • Requires maintaining a separate directory for each language

Cost implications

ccTLD:

  • Expensive
  • Each domain may require separate registration, set-up, and maintenance costs
  • May involve physical presence or other requirements

Subdomain:

  • Moderate
  • Requires purchase of one top-level domain unless using existing TLD
  • Costs increase if each subdomain is hosted in a separate market

Subdirectory:

  • Inexpensive
  • Requires purchase of one top-level domain

Hosting and content delivery networks (CDN)

One other key consideration is hosting your website and the use of CDNs. The popularity of CDNs has grown significantly over the past number of years as users demand faster access to online content, and in regions with less developed infrastructure and slower internet access.

Although nobody knows the exact details of how search engines rank websites, we know Google can penalize websites for slower delivery speeds. And there’s no shortage of evidence to show that better user experience results in lower bounce rates, more page views, and greater conversions. As Google’s focus on user experience increases, the importance of in-country hosting and CDNs will also increase.

What do the best websites do?

John Yunker of ByteLevel Research, an industry analyst, produces an annual report listing the world’s best global websites. We looked at the top 10 websites from his 2015 Web Globalization Report Card to see which multilingual URL structures are used:

*Booking.com—a top 10 global site—uses a structure based on query string parameters. Please also note that Yunker ranked Facebook ranked 2nd, but as Facebook.com is used globally, we omitted it here.

 

What does this table tell us? You can see that these organizations use a variety of structures, but the ccTLD approach is the most common. This makes sense, though, because these are large organizations with the ability to invest in a resource-heavy option. However, the subdirectory approach is probably the most common on the web. This is likely because many companies are working with smaller, tighter budgets.

Choosing a URL structure for global websites doesn’t have to be vexing. Use this background and side-by-side comparison to determine the most appropriate multilingual URL structure approach for your brand and your budget.
