Hreflang

What is Hreflang?

Hreflang is an HTML attribute used to indicate to search engines the intended language and regional targeting of a webpage. It helps search engines serve the correct version of a page to users based on their language and/or geographical location. This is crucial for international SEO, ensuring that users are presented with content in their preferred language or localized for their region.

How Hreflang Works

Hreflang is implemented in three primary ways:

1. HTML Tags: These are added directly to the HTML of the webpage.

   <link rel="alternate" href="https://example.com/page" hreflang="en">
   <link rel="alternate" href="https://example.com/page-fr" hreflang="fr">

2. HTTP Headers: Hreflang tags can also be specified in the HTTP headers of a page.

   Link: <https://example.com/page>; rel="alternate"; hreflang="en"
   Link: <https://example.com/page-fr>; rel="alternate"; hreflang="fr"

3. Sitemaps: Hreflang tags can be included in XML sitemaps.

   <url>
     <loc>https://example.com/page</loc>
     <xhtml:link rel="alternate" hreflang="en" href="https://example.com/page"/>
     <xhtml:link rel="alternate" hreflang="fr" href="https://example.com/page-fr"/>
   </url>

Why Hreflang is Important for SEO

1. Targeted Content Delivery:

• Hreflang helps ensure that users see content tailored to their language and region. This improves user experience and engagement.

2. Duplicate Content Management:

• It helps manage duplicate content issues by signaling to search engines that multiple versions of a page are intended for different audiences, preventing them from being flagged as duplicate content.

3. Improved Rankings:

• By correctly implementing hreflang tags, you can improve the chances of your content being served in relevant search results, thereby potentially boosting your rankings in different regions.

Best Practices for Implementing Hreflang

1. Always Use Self-Referencing Hreflang Tags:

• Every page should reference itself with an hreflang tag. This helps confirm the language and regional targeting of the page.

   <link rel="alternate" hreflang="en" href="https://example.com/page"/>

2. Use Valid Language and Region Codes:

• Language codes should follow the ISO 639-1 standard, and region codes should follow ISO 3166-1 Alpha 2. For example, use en-gb for British English, not en-uk.

   <link rel="alternate" hreflang="en-gb" href="https://example.com/page-uk"/>

3. Include an “x-default” Tag:

• The x-default tag serves as a fallback for users whose language or region isn’t specified.

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

4. Ensure Consistent Hreflang Tags Across All Versions:

• Every localized version of a page should include the full set of hreflang tags for all other versions and the x-default page.

   <!-- On the English page -->
   <link rel="alternate" hreflang="en" href="https://example.com/page"/>
   <link rel="alternate" hreflang="fr" href="https://example.com/page-fr"/>
   <link rel="alternate" hreflang="x-default" href="https://example.com/"/>
