Hreflang Tag Generator

Generate correct hreflang tags for your multi-language or multi-region site. Add each language/region version and copy the tags into your <head>.

Add your page versions

Your hreflang tags

Place these in the <head> of every version listed — hreflang must be reciprocal (each page links to all the others, including itself).

What Are Hreflang Tags and When Do You Need Them?

Hreflang tags tell search engines which language and regional version of a page to serve to which audience. When your site exists in multiple languages or targets multiple regions, our hreflang generator gives you the exact annotations that connect those versions so Google shows the right page to the right person.

You need hreflang tags in three scenarios: when you translate content into multiple languages, when you keep the same language but target different regions (English for the US versus English for the UK), or when you do both at once. Without these signals, search engines may show your US visitors a UK page, your Spanish readers an English page, or treat near-identical translations as duplicate content. If you run an international site and conversions are slipping in certain markets, hreflang is one of the first things our SEO and organic growth team audits.

Hreflang Syntax: How a Tag Is Built

Every hreflang annotation pairs a URL with a language (and optionally a region) code. In the HTML head, a single tag looks like this:

  • rel="alternate" signals an alternate version of the current page
  • hreflang="en-us" declares the language and region that version targets
  • href="https://example.com/us/" points to the matching URL

Put together, that is <link rel="alternate" hreflang="en-us" href="https://example.com/us/" />. You list one tag per version, and each page must list every version in the set, including itself.

Language vs. Language-Region Codes

The language portion uses an ISO 639-1 code: en for English, es for Spanish, de for German, fr for French. You can stop there if you simply want to target a language regardless of country.

To target a specific region, append an ISO 3166-1 Alpha 2 country code: en-us (English, United States), en-gb (English, United Kingdom), es-mx (Spanish, Mexico), pt-br (Portuguese, Brazil). A frequent error is using a code that is not valid for hreflang. For example, "uk" is not a country code for the United Kingdom; the correct value is gb. Note that the region code targets a country, not a continent or city, and the language code always comes first.

The x-default Tag

The reserved value hreflang="x-default" specifies the fallback page to serve when no other language or region in your set matches a visitor's browser settings. It is optional but recommended, because it lets you control what an unmatched user sees rather than leaving the choice to the search engine. Many sites point x-default at a language selector or their primary global homepage. Our generator adds the x-default line for you so the set is complete.

Three Ways to Implement Hreflang

There is no single required method. Choose whichever fits your stack:

  • HTML head: Place the <link rel="alternate" hreflang> tags inside the <head> of every page. Simple and the most common choice for smaller sites.
  • HTTP headers: Return the annotations as Link headers in the server response. This is how you add hreflang to non-HTML files such as PDFs.
  • XML sitemap: Use child <xhtml:link> entries under each <url> to list every variant. This keeps the markup out of your pages and is easiest to maintain at scale, similar to how you control crawl behavior with a robots.txt file.

Pick one method per page. Mixing methods for the same URL set creates conflicting signals.

The Critical Rule: Hreflang Must Be Reciprocal

Hreflang annotations have to be bidirectional. If page X points to page Y, then page Y must point back to page X. According to Google, the single most common hreflang mistake is missing return links, and when they are missing, the annotations may be ignored or interpreted incorrectly. Every page in a set should reference every other page in that set, including itself. Our generator outputs a complete, reciprocal block for the whole cluster so you can drop the matching tags onto each URL.

Common Hreflang Mistakes

  • Missing return tags, so the cluster is not reciprocal
  • Using invalid codes (for example "en-uk" instead of "en-gb")
  • Pointing to redirected, canonicalized, or non-indexable URLs
  • Using relative URLs; hreflang requires absolute, fully qualified URLs
  • Forgetting the self-referential tag on each page
  • Omitting an x-default for international audiences who match nothing
  • Mixing implementation methods for the same page

Hreflang FAQ

Is hreflang a ranking factor? No. It does not boost rankings directly; it makes sure the correct localized version appears, which improves relevance and the user experience in each market.

Do single-language sites need hreflang? No. It only applies when you have multiple language or regional versions of the same content.

Does hreflang replace a canonical tag? No. Each localized page should self-canonicalize, and the hreflang set connects the versions. Do not point hreflang variants at a single canonical.

How fast does it take effect? Search engines must recrawl every page in the set before they honor the annotations, so allow time after deployment.

Generate your tags above, validate that every version reciprocates, and confirm the rules against the Google Search Central guidance on localized versions. If your international setup is complex, contact our team and we will audit and build the full hreflang structure for you.
