What is Hreflang?
Hreflang is an HTML attribute used to specify the language and sometimes the target geographical region of a webpage. It informs search engines about the existence of multiple versions of the same page in different languages or regions, helping them serve the most relevant version to users based on their language settings and location.
How It Works
Function and Concept
Hreflang tags tell search engines about the relationship between webpages that are in different languages or targeted at different regions. This helps search engines determine which version of a page to display to users based on their location and language preferences.
Practical Use Cases
When a user performs a search, Google checks the page’s code for hreflang tags, considers the user’s current location and language settings, and displays the most relevant URL in the search results. For example, if a website has English, Spanish, and French versions of a page, each page must include hreflang tags pointing to all other versions, including a self-reference.
Syntax and Implementation
Hreflang tags use the following syntax: <link rel="alternate" hreflang="x" href="https://example.com/alternate-page"/>
where x
is the language code (e.g., en
for English) and optionally a country code (e.g., en-us
for English in the United States). For non-HTML pages like PDFs, the hreflang annotation can be added in the HTTP header.
Why It Matters
Importance in SEO
Hreflang tags help reduce the impact of duplicate content issues by informing search engines that similar pages are intended for different audiences, thus preventing penalties for duplicate content. They ensure that the right content is served to the right users, enhancing user experience and potentially improving conversion rates by showing users content in their preferred language and region.
Impact on Website Performance and Rankings
Proper use of hreflang tags can improve search engine rankings by ensuring that the most relevant version of a page is displayed to users, which can lead to better engagement and lower bounce rates. It helps in maintaining the credibility of the site by avoiding confusion caused by duplicate content and ensuring that search engines understand the structure of the site.
Best Practices
Recommended Methods and Strategies
Bidirectional Tags
Ensure that hreflang tags are bidirectional, meaning if an English page points to a Spanish page, the Spanish page must also point back to the English page.
Self-Referencing
Each page must include a self-referencing hreflang tag in addition to tags pointing to other language versions.
X-Default Tags
Use hreflang="x-default"
tags to specify a default or fallback page for users when no other language variant is appropriate. This is recommended by Google but not mandatory.
Correct Language and Country Codes
Use the correct two-letter ISO 639-1 language codes and optionally ISO 3166-1 alpha-2 country codes. For example, en
for English, en-us
for English in the United States.
Avoid Broken or Nonexistent Links
Ensure that hreflang tags do not point to redirected, broken, or nonexistent pages, as this can cause issues with how search engines interpret the tags.
Consistent Implementation
Implement hreflang tags consistently across all versions of the page to avoid confusion and ensure that search engines can accurately determine the relationships between the pages.
