Subdomains vs Subdirectories: Which is Better for SEO?

Although most businesses primarily target their local market or English-speaking audiences, there are instances where expanding into multiple markets and translating websites into different languages becomes crucial. The question then arises: should you use subdomains or subdirectories for creating these language-specific versions?

In this article, we will delve into the debate of subdomains vs subdirectories and explore the pros and cons of each approach. We will also examine the importance of having multiple language versions and targeting non-English speaking markets. By the end, you will have a better understanding of which method is more suitable for your website and how to approach language translations effectively.

1. Introduction

Expanding your website's reach beyond your primary market can be a lucrative strategy for businesses aiming to tap into new customer bases. When your target audience includes individuals who do not primarily speak English, offering translated versions of your website can significantly enhance user experience and drive more organic traffic.

In this article, we will analyze the debate of using subdomains versus subdirectories for creating these language-specific versions. We will explore the benefits and challenges of each approach, consider the test results and rankings, and provide recommendations on the best practices for implementing multiple language versions.

2. Subdomains vs Subdirectories

Before diving into the details, let's establish what we mean by subdomains and subdirectories. A subdomain is a partially separate section of a website that has its own unique URL and is treated as a separate entity by search engines. For example, would be the French version of a website. On the other hand, a subdirectory is a subdivision of the main website, indicated by a folder in the URL structure. For instance, represents the French version of a website.

Both subdomains and subdirectories have their advantages and disadvantages, which we will explore in the following sections.

3. The Importance of Multiple Language Versions

When expanding into international markets or targeting non-English speakers, having translated versions of your website is crucial. It not only allows you to cater to a wider audience but also improves user experience, increases credibility, and enhances your chances of attracting organic traffic.

By providing content in the local language, you demonstrate your commitment to understanding and addressing the needs of your target audience. This level of personalization can go a long way in building trust and establishing your brand as a reliable source of information or products among international users.

4. Targeting Non-English Speaking Markets

While many businesses may operate within their own country or language, there are regions where non-English speakers form a significant portion of the population or target audience. In such scenarios, translating your website into the local language can give you a competitive edge.

For instance, if you are located in a region with a strong Hispanic market or a sizable non-English speaking community, offering versions of your website in Spanish or the relevant language can help you connect with potential customers more effectively. This localized approach shows your commitment to understanding the nuances of the market and can significantly impact conversions.

Pros of Subdomains

  • Clear separation: Subdomains allow for a clear separation of language versions, making it easier to manage and modify each version independently.
  • Targeted optimization: With separate subdomains, you can optimize each version for specific keywords and search intent, increasing your visibility in local search results.
  • Geotargeting advantages: Search engines often consider subdomains as separate entities, boosting their geotargeting capabilities and increasing the chances of ranking higher in localized search results.

Cons of Subdomains

  • Duplicate efforts: Managing and maintaining multiple subdomains can be time-consuming and requires duplicating efforts in terms of plugins, coding, and content updates.
  • SEO efforts spread thin: With each subdomain being treated as a separate website by search engines, SEO efforts need to be divided among multiple domains, often resulting in diluted rankings and authority.

Pros of Subdirectories

  • Centralized management: With subdirectories, all language versions are housed within a single domain, making it easier to manage, update, and optimize the website as a whole.
  • Shared authority: By consolidating all language versions under one domain, the overall authority of the website is boosted, benefiting all versions collectively.
  • Simplified SEO: SEO efforts can be focused on a single domain, allowing for better optimization and more effective targeting of keywords.

Cons of Subdirectories

  • Limited keyword differentiation: Subdirectories restrict the ability to optimize each language version for specific keywords, potentially limiting visibility in search results.
  • Language-based interlinking challenges: Interlinking between language versions becomes more complex with subdirectories, requiring careful implementation of hreflang tags to ensure accurate language targeting.

5. Factors to Consider When Choosing Between Subdomains and Subdirectories

When deciding which approach to use, several factors come into play, including the nature of your business, target audience, scale of localization, and technical feasibility. It's essential to evaluate these factors and understand how they align with your business goals and resources.

  1. Business goals and resources: Consider the long-term objectives of your business and the resources available to manage multiple language versions.
  2. Target audience and market segmentation: Analyze your target audience's language preferences and geographical locations to determine the level of customization required.
  3. SEO strategy: Evaluate the impact on your SEO strategy, keeping in mind factors like keyword targeting, link equity distribution, and potential duplicate content issues.
  4. Technological considerations: Assess the technical complexity of implementing subdomains or subdirectories, such as content management systems, server configurations, and multilingual plugins.

By carefully considering these factors, you can make an informed decision and choose the approach that best suits your website's localization needs.

6. Case Study: Rankings and Test Results

To provide insights into how subdomains and subdirectories perform in real-world scenarios, several tests have been conducted by SEO experts and practitioners. These tests analyze the impact of website structure on rankings and user experience, contributing to the ongoing debate.

Subdomains vs Subdirectories: Our Test Results

In our test, we examined the performance of subdomains and subdirectories for a website targeting different language versions. Our findings revealed that using subdomains tended to yield better results, both in terms of rankings and user engagement.

However, it is important to note that our test considered specific parameters and may not be universally applicable. Each website and market is unique, and results may vary depending on various factors including competition, search algorithms, and user behavior.

Other Test Results in Favor of Subdomains

While our test favored subdomains, other experiments conducted by industry experts have shown mixed results. Some tests indicate that subdomains outperform subdirectories in terms of ranking performance and localized targeting. This suggests that search engines perceive subdomains as separate entities with distinct relevance to particular markets.

Other Test Results in Favor of Subdirectories

On the contrary, there are cases where subdirectories have outperformed subdomains. These tests highlight the benefits of consolidating authority and optimizing a single domain instead of spreading SEO efforts across multiple subdomains. For websites with limited resources or smaller-scale localization, subdirectories offer simplicity and efficiency.

7. Recommendations and Best Practices

Based on our analysis and the collective findings of various tests, we offer the following recommendations and best practices for implementing multiple language versions:

  1. Using Hreflang Tags: Hreflang tags play a crucial role in indicating language and regional targeting to search engines. Implementing these tags correctly is essential for ensuring accurate language associations and avoiding duplicate content issues.
  2. The Importance of Interlinking: Whether you choose subdomains or subdirectories, interlinking between language versions is essential. Internal linking helps search engines discover and navigate between different language versions, improving indexation and user experience.
  3. Regular Content Updates: Keeping your translated content updated and relevant is crucial for maintaining user engagement and search engine visibility. Translations should be accurate, culturally appropriate, and reflect the local context.
  4. Localized Keyword Research: Conducting keyword research specific to each language version will help you optimize your content for local search queries and improve rankings.
  5. User Experience Optimization: Pay attention to the user experience of each language version, including language-specific URLs, navigation, and localization of elements like currencies, addresses, and phone numbers.

10. Conclusion

Expanding your website's reach by creating multiple language versions is a strategic move that can improve user experience, attract organic traffic, and enhance conversions. When it comes to deciding between subdomains and subdirectories, there is no one-size-fits-all solution.

Consider the unique needs of your business, target audience, and available resources to choose the approach that aligns best with your goals. Implement best practices such as using hreflang tags, optimizing interlinking, and regularly updating your translated content to ensure success in your localized SEO efforts.

Remember, while subdomains may offer better localized targeting, they come with added complexity and required duplication of efforts. Subdirectories, on the other hand, provide simplicity and centralized management but limit keyword differentiation.

Ultimately, finding the right balance between SEO effectiveness and efficiency is key to achieving success with multiple language versions.
