2. Help Google Understand Your Language Versions
Why It Matters
For multilingual websites, it’s crucial that Google can identify and understand each language version of your content. This allows Google to index and rank each version separately, ensuring your content reaches the right audience.
What to Do
To help Google recognize your language versions, follow these steps:
- Use a clear URL structure for each language, such as subdomains (e.g., en.example.com, es.example.com) or subdirectories (e.g., example.com/en, example.com/es).
- Avoid using cookies or session variables to determine the language version.
- Add the
hreflang
tag to the HTML header of each language version. This tag tells Google about the available language versions. - Create a sitemap for each language version and submit it to Google Search Console. This helps Google understand your website’s structure and crawl each version efficiently.
Tools to Help
To simplify the process, consider using plugins like WPML or Polylang. These plugins can automatically generate the hreflang
tag and create separate sitemaps for each language version. They also help manage your multilingual content and ensure proper indexing and ranking by Google.

3. Choose the Right URL Structure
Why It Matters
The URL structure you choose for your multilingual website plays a vital role in helping search engines understand the language and location of your content. This ensures that your website reaches the right audience, improving visibility and user experience.
Options to Consider
When selecting a URL structure, you have three main choices:
-
Subdirectories: Use subdirectories for each language, like
example.com/en/
for English andexample.com/fr/
for French. This approach is straightforward to set up and maintain. -
Subdomains: Use subdomains for each language, such as
en.example.com
for English andfr.example.com
for French. This option offers more flexibility for geo-targeting. -
Country-specific domains: Use country-specific domains, like
example.co.uk
for the UK andexample.fr
for France. This approach works well for businesses with a strong local presence.

4. Implement the hreflang Attribute Correctly
Why It’s Important
The hreflang
attribute helps search engines understand which language and region your website’s content is intended for. This ensures that the right version of your site is shown to users based on their language and location settings, improving visibility and user experience.
How to Do It
- Define language and region codes: Use standard ISO codes – ISO 639-1 for languages (e.g., "en" for English) and ISO 3166-1 Alpha 2 for regions (e.g., "US" for United States).
-
Add the
hreflang
attribute: In the<head>
section of your HTML pages, specify the language and region codes for each version of your website using thehreflang
attribute. -
Use absolute URLs: Make sure the URLs in your
hreflang
attribute include the full protocol (e.g., "https://") and domain name. -
Reference all versions: Include
hreflang
tags for the current page and its translated versions. -
Test and validate: Use tools like Google Search Console or plugins to verify that search engines can properly crawl and understand your
hreflang
implementation.

Relying solely on automatic translation tools like Google Translate can harm your website’s ranking and user experience.

This can damage your website’s credibility and authority in the eyes of search engines.
What to Do
To ensure high-quality translations, follow these steps:
- Use human translators: For important content like your homepage, about page, or product descriptions, hire human translators to ensure accuracy and cultural relevance.
- Review and edit machine translations: If you use machine translation tools, have a human reviewer edit and refine the translations to meet your quality standards.
