What are Hreflang Tag Attributes? Implementation Guide

In the ever-changing landscape of online marketing, employing the right strategies can make or break your digital presence. One of these essential strategies is understanding and implementing the hreflang attribute, a vital component of technical SEO, and an integral part of your local Content Strategy.

Understanding what hreflang is, how it works, and how to use it effectively is a critical step in optimizing your website for a global audience.

What is the Hreflang Attribute?

Hreflang is an HTML tag used to specify the language and geographical targeting of a webpage. It’s a signal to search engines like Google to show the correct language version of a page to a user searching in that language.

If your website has content in multiple languages, implementing hreflang is essential. It helps search engines understand the relationship between various language versions of the same content, thereby serving the most relevant version to the user.

The “link rel alternate” tag is an essential companion to hreflang. It’s used to tell search engines that alternate localized versions of the content are available in different languages or for different devices.

Hreflang implementation plays a crucial role in serving the right content to the right audience. Here are some real-life examples to help illustrate how this can be done creatively and comprehensively:

1. Multilingual Website:

For websites that offer content in multiple languages, hreflang guide search engines to serve the correct language version.

Example HTML:

This setup ensures that English-speaking users see the English version, while French-speaking users see the French version.

2. Regional Variations:

When targeting different regions that speak the same language, hreflang can differentiate between regional dialects or variations.

Example HTML:

<link rel="alternate" hreflang="en-GB" href="https://www.example.co.uk/" /> <link rel="alternate" hreflang="en-US" href="https://www.example.com/" />

This directs users in the UK to the British English version and users in the US to the American English version.

Example HTML:

<link rel="alternate" hreflang="es-MX" href="https://www.example.com/mx/" /> <link rel="alternate" hreflang="es-AR" href="https://www.example.com/ar/" />

This provides a seamless shopping experience for customers in Mexico and Argentina by displaying prices and shipping information in the local context.

4. Fallback Options:

Including a fallback option helps in serving content when a specific language or regional variation is not available.

Example HTML:

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

This tag directs users to a default version if their language or region is not explicitly targeted.

5. Combining with Canonical Tags:

Hreflang attributes can be combined with canonical URLs to clarify the relationship between similar content in different languages or regions.
