What is Hreflang SEO? Best Practices To Rank Globally in 2025

March 24, 2025

If your website features content in multiple languages, mastering the hreflang attribute is essential. Hreflang is an HTML code you can implement on your site to indicate the intended language and regional audience for each webpage to search engines.

It acts like a map, guiding Google and others to display the appropriate language version to the right users. While Hreflang SEO is a powerful tool for global reach, it’s important to remember that hreflang serves as a signal rather than a directive.

Understanding this distinction is key to using Hreflang SEO effectively in your digital strategy. Continue reading to learn more about implementing and optimizing this crucial attribute.

What is Hreflang?

Hreflang is an HTML attribute that helps search engines understand the language and region a web page is intended for. This ensures users see content in their preferred language and region.

For instance, the hreflang attribute hreflang=”en-AE” tells search engines this page is in English and meant for users in the United Arab Emirates.

If your website offers different language or country versions of its pages, using hreflang is a crucial part of your SEO strategy to ensure the right audience finds the right content.

Importance of Hreaflang for SEO

When managing a multilingual website, strategically implementing hreflang tags is key to enhancing user experience and search engine optimization. Here’s why incorporating hreflang is crucial:

Search Engine Usage: Google and Yandex rely on hreflang tags to direct users to the appropriate language version of a page. This ensures that content is relevant and accurately targeted. While Bing views hreflang as a secondary signal, it still acknowledges its importance in their guidelines. Conversely, Baidu does not consider hreflang tags at all.
Improved User Experience: Hreflang enhances user engagement by matching content with the user’s language preferences. This leads to better interaction metrics like longer dwell times and lower bounce rates.
SEO and Rankings Impact: Google expert Gary Illyes highlights that hreflang tags can directly influence rankings. Hreflang enables pages within a cluster to share ranking signals. This effectively manages duplicate content across different languages, boosting the overall SEO strength of the website.
Content Relevance: Implementing hreflang ensures that search engines display the most relevant page version in search results. This optimizes both user satisfaction and content visibility.

How to Implement Hreflang?

Implementing hreflang is essential for websites with content targeted at audiences speaking different languages or residing in various countries. Here’s a step-by-step guide on how to effectively apply hreflang tags to optimize your site for global search engines:

Step 1: Identify Multilingual Content

Start by identifying pages on your site that have the same content in different languages or are targeted at different regions. Each of these pages will need a specific hreflang tag to indicate its target audience.

Step 2: Understand the Hreflang Tag Anatomy

The basic format of an hreflang tag is hreflang=”value,” where the value is defined as:

Language Code: Use a two-letter ISO 639-1 code that specifies the language (e.g., en for English). Apply this when the content is intended as a default for all speakers of the language.
Language and Country Code: Combine the ISO 639-1 language code with an ISO 3166-1 alpha-2 country code, separated by a hyphen (e.g., en-us for English, United States). Use this for content targeted at a specific country.
X-Default: Use x-default for the global or default version of your page when no other variant matches the user’s language.

Step 3: Implementing Hreflang Tags

There are several methods to implement hreflang tags:

Hreflang in HTML Headers

Include the hreflang tag in the <head> section of your HTML. Each page should reference itself and its alternate versions, using tags like:

This method is straightforward and helps search engines understand the language and regional targeting of each page.

Hreflang in XML Sitemaps

Incorporate hreflang tags in your XML sitemap, providing search engines with comprehensive mapping of language and region variants across your site. Structure it like:

<url>

<loc>https://www.example.com/</loc>

<xhtml:link rel=”alternate” href=”https://www.example.com/” hreflang=”x-default” />

<xhtml:link rel=”alternate” href=”https://www.example.com/gb/” hreflang=”en-gb” />

</url>

<url>

<loc>https://www.example.com/gb/</loc>

<xhtml:link rel=”alternate” href=”https://www.example.com/” hreflang=”x-default” />

<xhtml:link rel=”alternate” href=”https://www.example.com/gb/” hreflang=”en-gb” />

</url>

This method is ideal for extensive sites with multiple language versions, ensuring all URLs are indexed correctly.

Hreflang in HTTP Response Headers

For non-HTML content like PDFs, implement hreflang through HTTP response headers:

<https://www.example.com/>; rel=”alternate”; hreflang=”x-default”, <https://www.example.com/us/>; rel=”alternate”; hreflang=”en-us”

This informs search engines about the language and region for each file type that doesn’t support standard HTML tags.

Step 4: Regular Updates and Audits

Regularly update and audit your hreflang implementation to address any errors and ensure compliance with search engine guidelines. Use CMS plugins or seek assistance from web developers if needed.

Using these steps, you can implement hreflang tags to enhance your site’s global SEO. This can ensure the correct language version reaches your international audience.

Best Practices for Hreflang SEO

Optimize your global SEO by adhering to hreflang best practices. These key strategies will ensure your content reaches the right audience:

Use Canonical URLs in Hreflang Tags

Always use canonical URLs in your hreflang tags to prevent confusion for search engines. A canonical URL is the principal address of a webpage, designated as the authoritative version for search engines to index. Alternate addresses, which might redirect or point to the canonical URL, should not be used in hreflang annotations. For instance, if your webpage is accessible through multiple URLs, ensure that the hreflang tag references only the canonical URL:

Correct: https://www.example.com/en/
Incorrect: https://www.en.example.com/ or example.com/en

Avoid using URLs in your hreflang tags that:

Are redirected (301) to other URLs.
Have a canonical tag pointing elsewhere.
Lead to a 404 error or are otherwise broken.

Keep Your Hreflang Code Updated

It’s essential to keep hreflang annotations updated to reflect changes in your site’s content structure:

If you add a new language version, such as German, incorporate the correct hreflang tags for the new pages into your sitemaps or HTML.
Update existing tags to ensure all language versions are correctly cross-referenced. This prevents any outdated links that can mislead search engines.

Audit Your Website for Hreflang Issues

Regularly auditing your website for hreflang issues helps identify and rectify mistakes that might impact your SEO. Tools like Semrush’s Site Audit can assist in finding common issues such as:

Invalid hreflang values.
Pages lacking self-referencing hreflang attributes.
Missing hreflang attributes on some pages.
Links to non-canonical or broken URLs.
Discrepancies between the page’s content language and the hreflang code.

Following these best practices enhances international SEO by ensuring correct multilingual content display. This proactive approach minimizes errors and optimizes your site for global users.

Common Mistakes When Implementing Hreflang Attribute

Careful implementation of hreflang is crucial to prevent SEO issues. Here’s a look at some typical mistakes to watch out for when setting up hreflang tags:

1) Using Incorrect Language or Country Codes

One of the most frequent errors in hreflang implementation is the misuse of language and country codes. These codes are essential for correctly targeting the appropriate audience, but they can be counterintuitive.

For instance, the correct country code for the United Kingdom is “GB” (Great Britain), not “UK” (United Kingdom). Similarly, for content targeting Hong Kong, you should use “zh-HK” instead of “zh-CN,” designated for mainland China.

To prevent such errors, always verify the accuracy of your codes against the official ISO standards for language and country codes. This ensures your content reaches the correct demographic and enhances site relevance for users in specific regions.

2) Wrong Use of Canonical and Href Tags

When managing multilingual versions of a website, it’s crucial to use hreflang and canonical tags correctly. These tags serve distinct yet complementary purposes. Hreflang tags inform search engines about the language and regional targeting of a page. This helps ensure that the correct content version is shown to users based on their geographic and language preferences.

For example, if you have a webpage available in English for the United States and another in Spanish for Mexico, each version should include not only hreflang tags but also a canonical tag pointing to its respective URL. This is crucial for maintaining clear signals to search engines about which versions are essential and how they should be indexed. Here’s how it should look:

For the US version:

For the Mexico version:

3) Same URL for Alternative Pages

A common mistake in hreflang implementation is assigning multiple language or regional versions of a page to the same URL. Each version of a page should have its own unique URL to correctly guide search engines and users to the appropriate version of the content.

For instance, it’s incorrect to point different regional versions to the same URL as it causes confusion for search engines, which may struggle to serve the correct content to the right audience:

Instead, ensure that each hreflang link element points to its specific regional or language URL. This helps search engines understand that each page variant is distinct and intended for a different audience, thus preventing errors in content delivery:

Tools for Hreflang Tag Implementation and Audit

Implementing and auditing hreflang tags can be complex, especially for large websites with multiple international versions. Fortunately, there are tools available to simplify this process, ensuring correct implementation and effective management.

1) CMS Plugins

Many Content Management Systems (CMS) offer plugins designed to handle hreflang implementation. These plugins can automate the process, reducing human error and saving time.

For example, WordPress users can use plugins like Polylang or WPML, which automatically add the appropriate hreflang tags for each language version. These tools are invaluable for managing multilingual content efficiently.

2) AI Tools

AI tools like ChatGPT can also assist in generating hreflang attributes for your web pages. While these tools can provide a solid starting point, it’s crucial to double-check the generated codes for accuracy before implementation.

For integrating hreflang tags, you can use ChatGPT to:

Create hreflang HTML code: Prompt ChatGPT to generate the necessary HTML tags for each language or regional version of your site, which you can then embed directly into your HTML headers.

Generate an XML sitemap: ChatGPT can help create XML sitemaps that include hreflang information, making it easier to manage multiple URLs and ensure that search engines correctly index your site’s international versions.

Implement HTTP headers for non-HTML files: For content like PDFs, ChatGPT can provide guidance on implementing hreflang tags through HTTP headers, ensuring even non-HTML content is properly localized and accessible.

To effectively use AI tools like ChatGPT for these tasks, tailor your prompts to reflect your specific needs. You may need to experiment a bit to optimize the tool’s output for your particular site structure and scale.

3) Online Hreflang Generators

There are websites that allow you to input your page URLs and language versions, and they’ll generate the correct hreflang code ready for you to copy and paste.

Aleyda Solis Hreflang Tags Generator Tool: A free and straightforward tool to generate your hreflang tags.

SISTRIX hreflang Generator: Another excellent tool with the added ability to validate existing hreflang tags.

4) Screaming Frog for Hreflang Tag Audit

Screaming Frog is an effective SEO tool for auditing hreflang tags on your website. It simulates search engine crawling, allowing you to spot and correct hreflang issues.

Here’s how Screaming Frog can aid in hreflang audits:
