Worked example — 4 hreflang tags generated (3 languages + x-default)
Formula
<link rel="alternate" hreflang="lang-REGION" href="URL" />
Hreflang tags use ISO 639-1 language codes and optional ISO 3166-1 Alpha-2 region codes. Each page must reference all language versions including itself. The x-default value serves as a fallback for unmatched users.

Frequently Asked Questions
What are hreflang tags and why are they important for international SEO?
Hreflang tags are HTML attributes that tell search engines which language and regional version of a page to serve to users based on their location and language preferences. They are implemented as link elements in the HTML head, XML sitemap entries, or HTTP headers. Without hreflang tags, search engines may show the wrong language version of your content to users, or treat translated pages as duplicate content and penalize your rankings. Google processes hreflang as a signal rather than a directive, meaning it uses the tags as strong hints but may override them based on other factors. Properly implemented hreflang tags improve user experience by directing visitors to content in their preferred language and can significantly boost organic traffic in international markets.
How do you format hreflang language and region codes correctly?
Hreflang codes follow the ISO 639-1 standard for language codes and ISO 3166-1 Alpha-2 for region codes. The language code is always lowercase and required, such as en for English, es for Spanish, or fr for French. The region code is optional, uppercase, and separated by a hyphen, such as en-US for American English, en-GB for British English, or pt-BR for Brazilian Portuguese. You should use region codes when you have multiple versions of the same language targeting different countries, like separate pages for Spanish speakers in Spain versus Mexico. The special value x-default designates the fallback page for users whose language or region does not match any specified version. Common mistakes include using incorrect codes, using underscores instead of hyphens, and forgetting that codes are case-sensitive.
What is the x-default hreflang tag and when should I use it?
The x-default hreflang value designates the default or fallback page that should be shown to users when no other hreflang tag matches their language or region. It acts as a catch-all for visitors from locations or language settings not covered by your specific language versions. You should almost always include an x-default tag in your hreflang implementation. Typically it points to your main language version, an international English page, or a language selector page. For example, if you have pages in English, Spanish, and French, the x-default would usually point to the English version or a page where users can choose their language. Without x-default, search engines must guess which version to show unmatched users, which may result in suboptimal page selections that hurt user experience.
What are the three methods for implementing hreflang tags and which is best?
There are three implementation methods for hreflang tags. First, HTML link elements placed in the head section of each page, which is the most common and straightforward approach for smaller sites. Second, XML sitemap entries using xhtml link elements, which is ideal for large sites with many language versions since it centralizes management and does not add overhead to page HTML. Third, HTTP response headers, which is the only option for non-HTML files like PDFs. For most websites, the HTML method is sufficient and easiest to maintain. Large enterprises with hundreds of language-region combinations typically prefer the sitemap method. The critical rule is that you must only use one method per page, never mix methods. Regardless of method, every page must include self-referencing hreflang tags pointing back to itself.
What are common hreflang implementation mistakes and how do I avoid them?
The most frequent hreflang mistakes include missing return tags, which means every page referenced in hreflang must also contain hreflang tags pointing back to all other versions including itself. Non-canonical URLs in hreflang tags cause conflicts because the hreflang URL must match the canonical URL exactly. Using incorrect language or region codes, such as uk instead of the correct en-GB for British English, causes tags to be ignored. Inconsistent protocols between http and https versions create mismatches. Forgetting the x-default tag leaves unmatched users without a clear fallback. Mixing implementation methods on the same page creates confusion for search engine crawlers. Finally, not keeping hreflang tags updated when URLs change leads to broken references that can harm all language versions of your pages.
