In today's globalized world, businesses are expanding their reach beyond borders and targeting international markets. This has made international SEO and multilingual websites more important than ever. One crucial aspect of international SEO is the implementation of hreflang tags. In this article, we will explore what hreflang is, why it is essential for international SEO, and how to effectively implement it on your website.

What is hreflang and why is it important for international SEO?

Hreflang is a special HTML tag introduced by Google in 2011. It is used to signal to search engines the language and regional targeting of web pages. This helps search engines display the appropriate version of a webpage based on the user's language and location. For websites with multiple language options, hreflang is crucial for delivering the right content to the right audience. Without hreflang, search engines may not be able to determine the correct language version of a page, leading to irrelevant search results and a poor user experience.

How does hreflang work?

Hreflang tags work by indicating the language and country targeting of web pages. The hreflang attribute is added to the HTML code of a webpage and contains the language code and optionally the country code. When a user performs a search, search engines use hreflang tags to determine which version of the webpage to display based on the user's language and location. It acts as a powerful signal to search engines, ensuring accurate language targeting and improving search visibility for international audiences.

Implementing hreflang on a website

There are several ways to implement hreflang on a website, depending on the website structure and content management system (CMS) used. The three common methods are using subdomains, using subfolders, and using multilingual plugins.

Using subdomains

One method of implementing hreflang is by using subdomains. For example, the English version of a website can be hosted on "" and the German version on "". This approach allows you to separate different language versions into distinct subdomains and helps search engines understand the language targeting of each section.

Using subfolders

Another method is to use subfolders. With this approach, different language versions are organized within subfolders of the main domain. For instance, the English version may be found at "" and the German version at "". This method is especially useful when working with a single domain and targeting multiple languages.

Using multilingual plugins

For websites built on content management systems like WordPress, multilingual plugins can simplify the implementation of hreflang. Plugins such as PolyLang and TranslatePress automatically generate hreflang tags based on the language versions and content you create. These plugins offer user-friendly interfaces and handle the technical aspects of hreflang implementation, making it easier for website owners to manage multilingual content.

Best practices for implementing hreflang

When implementing hreflang, there are some best practices to consider for optimal results.

Language codes

Use the appropriate language codes to specify the language targeting of your web pages. Language codes are standardized and help search engines understand the intended content language. For example, "en" represents English, "de" represents German, and so on. Ensure consistent and accurate usage of language codes across your website.

Targeting specific countries

If your website has country-specific content, you can combine the language code with a country code to target specific regions. For example, "en-us" represents English targeting the United States, and "en-au" represents English targeting Australia. This level of granularity helps search engines deliver the most relevant content to users based on their country and language preferences.

Common mistakes to avoid when using hreflang

While implementing hreflang, there are some common mistakes that website owners should avoid to ensure its effectiveness.

  1. Incorrect language codes: Ensure that the language codes used in hreflang tags are accurate and standardized. Using incorrect language codes can lead to search engines misinterpreting the language targeting of your web pages.

  2. Missing or incomplete hreflang tags: Make sure to include hreflang tags on all relevant pages. Missing or incomplete hreflang tags can prevent search engines from understanding the language targeting of your content, resulting in improper search results.

Tracking hreflang performance

Once hreflang is implemented on your website, it is essential to track its performance and make necessary adjustments for optimal results. Here are two methods to monitor hreflang performance:

Using Google Search Console

Google Search Console provides valuable insights into how your website is performing in search results. It allows you to check if hreflang tags are correctly implemented and if there are any errors or issues. Regularly monitoring the International Targeting report in Google Search Console can help identify and resolve any problems with hreflang tags.

Monitoring website traffic

Keep a close eye on your website's traffic from different language and country versions. Analyzing traffic patterns can help you understand if the correct language version is being displayed for each region. If you notice any discrepancies, it may indicate a need for adjustments in your hreflang implementation.

Pros of using hreflang

  • Improved user experience: Hreflang ensures that users are presented with content in their preferred language, enhancing their browsing experience and engagement on your website.

  • Targeted international SEO: By implementing hreflang correctly, you can optimize your website's visibility and ranking in specific countries or language markets, attracting relevant organic traffic.

Cons of using hreflang

  • Implementation complexity: Hreflang implementation can be challenging, especially for websites with large amounts of content or complex site structures. It requires attention to detail and accurate implementation to avoid errors.

  • Maintenance and updates: As your website evolves or you add new language versions, keeping hreflang tags up to date and correctly implemented can be time-consuming.


Hreflang is a vital element of international SEO and multilingual websites. It ensures that search engines display the correct language version of your web pages, delivering a personalized and relevant experience to users across different countries and languages. By implementing hreflang correctly and adhering to best practices, you can improve your website's visibility, attract targeted organic traffic, and create a seamless user experience for your international audience.
