Definition
Hreflang is an HTML attribute used to specify the language and regional targeting for a webpage. It helps search engines understand which version of a webpage to display to users based on their language and geographical location. This is particularly important for websites that have multiple versions of content tailored for different languages and regions. By using hreflang tags, webmasters can improve the user experience by ensuring that users are directed to the most appropriate version of a webpage.
Hreflang attributes are added to the HTML link element in the head section of a webpage or included in the HTTP header. The attribute uses language codes (e.g., “en” for English) and optionally regional codes (e.g., “en-US” for United States English) to indicate the language and locale of the content. For example, a webpage with versions in both British English and American English would use hreflang tags to tell search engines which version to show to users in the UK and the US, respectively.
How You Can Use Hreflang
Example
Consider an e-commerce website that sells products internationally with different versions of its site for various languages and regions. The site has separate pages for English speakers in the US and the UK, as well as a Spanish version for users in Spain. To ensure that users are directed to the correct version, the webmaster would implement hreflang tags as follows:
- US English Page (
example.com/en-us/):htmlCopy code<link rel="alternate" hreflang="en-us" href="https://www.example.com/en-us/" /> <link rel="alternate" hreflang="en-gb" href="https://www.example.com/en-gb/" /> <link rel="alternate" hreflang="es-es" href="https://www.example.com/es-es/" /> <link rel="alternate" hreflang="x-default" href="https://www.example.com/" /> - UK English Page (
example.com/en-gb/):htmlCopy code<link rel="alternate" hreflang="en-us" href="https://www.example.com/en-us/" /> <link rel="alternate" hreflang="en-gb" href="https://www.example.com/en-gb/" /> <link rel="alternate" hreflang="es-es" href="https://www.example.com/es-es/" /> <link rel="alternate" hreflang="x-default" href="https://www.example.com/" /> - Spanish Page (
example.com/es-es/):htmlCopy code<link rel="alternate" hreflang="en-us" href="https://www.example.com/en-us/" /> <link rel="alternate" hreflang="en-gb" href="https://www.example.com/en-gb/" /> <link rel="alternate" hreflang="es-es" href="https://www.example.com/es-es/" /> <link rel="alternate" hreflang="x-default" href="https://www.example.com/" />
Formulas and Calculations
While hreflang itself does not involve calculations, it requires careful implementation to avoid errors. Here’s a simplified formula to ensure correct hreflang usage:
- Identify Language and Region Codes: Use ISO 639-1 for language codes (e.g., “en” for English, “es” for Spanish) and ISO 3166-1 Alpha 2 for region codes (e.g., “US” for the United States, “GB” for the United Kingdom).
- Create Hreflang Tags for Each Page Version: For each version of your page, create hreflang tags pointing to all other language and regional versions.
- Include a Default Hreflang Tag: Use
hreflang="x-default"for a default version of the page to serve users who do not match any specified language or region.
