Hreflang tags are essential HTML attributes that help search engines determine the appropriate language and regional version of a webpage to display for users. These tags are crucial for multilingual and international websites, ensuring that visitors see the correct content tailored to their language and location. For example, a company with separate English-language pages for the United States and Canada would use:
<link rel="alternate" hreflang="en-us" href="https://example.com/us/" /><link rel="alternate" hreflang="en-ca" href="https://example.com/ca/" />Without hreflang tags, search engines might show the wrong version of a page, leading to a poor user experience and potential loss of engagement or sales.
There are multiple ways to implement hreflang tags on a website. The most common method is by placing them in the <head> section of each page. This approach works well for HTML content but can increase server load times, especially for websites with extensive multilingual content. For non-HTML content like PDFs, hreflang tags can be placed in HTTP headers instead. Another efficient method is using XML sitemaps to store all hreflang attributes in one location, reducing potential errors and improving site performance. Whichever method is chosen, consistency and accuracy in applying hreflang tags are vital for ensuring search engines correctly interpret the intended audience for each page.
Hreflang tags also help prevent duplicate content issues, which can arise when similar or identical pages exist in different languages or regional versions. Search engines might mistakenly classify these pages as duplicate content and choose only one to rank, potentially lowering visibility for other language versions. By implementing hreflang correctly, website owners signal to search engines that these pages are distinct and should be ranked based on the user's language and location. However, hreflang tags are not absolute directives; Google still considers other SEO factors, such as page load speed, mobile optimization, and domain authority, when determining which page to display.
Proper implementation of hreflang tags requires careful planning, including using correct language (ISO 639-1) and country (ISO 3166-1) codes.
Common mistakes include missing return links, using incorrect codes, adding hreflang tags only to the homepage instead of all multilingual pages, and applying hreflang attributes to noindexed pages.
Additionally, failing to provide a fallback page using hreflang="x-default" can lead to a poor experience for users whose language or region is not explicitly targeted. Regularly checking hreflang implementation using tools like Google Search Console, specialized hreflang checkers or our own tool can help identify and fix errors.
