Title: Hreflang Tag Author: Kriko Published: Feb 25, 2021 Last modified: Jul 13, 2026 --- 1. [Home](https://kriko.io/) / 2. [Glossary](https://kriko.io/glossary) / 3. H Letter # Hreflang Tag The **hreflang tag** is an HTML annotation used on multilingual or multi-regional websites to tell search engines about different language and country versions of the same or similar content. With this tag, Google can better understand which language or regional audience a page is intended for and try to show the most appropriate URL to the right user. Hreflang is an important technical SEO element, especially in international SEO projects. The hreflang tag does not create a new language version of a page. In other words, adding hreflang to a Turkish page does not automatically generate an English page. The English, German, French or any other targeted language version must already exist on a separate URL. Hreflang only tells search engines about the relationship between these alternative pages. For this reason, multilingual websites should plan translation, URL structure and hreflang implementation together. For example, a website may have Turkish and English versions of the same service page. The Turkish page may be intended for Turkish-speaking users in Turkey, while the English page may be intended for users searching in English. The hreflang tag communicates this relationship to Google and helps the search results show the page that better matches the user’s language or regional settings. This can improve user experience and reduce the risk of showing the wrong language version. Hreflang is especially important when similar content is published in different country or language versions. For example, if English content is published separately for the United States, the United Kingdom and Australia, these pages should be marked with the correct regional codes. Generic English can be marked as `en`, US English as `en-us`, UK English as `en-gb` and Australian English as `en-au`. A common mistake is using `uk` for the United Kingdom; the correct hreflang value for UK English is `en-gb`. Hreflang values use a language code and, optionally, a regional code. Language codes are usually based on ISO 639-1; for example, `tr` for Turkish, `en` for English and `de` for German. Region codes are based on ISO 3166-1 Alpha-2; for example, ` tr` for Turkey, `us` for the United States and `gb` for the United Kingdom. Hreflang values are commonly written in lowercase, but the most important point is that the codes are valid and correctly matched. One of the most critical rules in hreflang implementation is reciprocal linking. If the English version of a page points to the Turkish version, the Turkish version should also point back to the English version. Each page should also include itself in the hreflang set. For example, if a page has Turkish, English and German versions, each version should list all alternative URLs, including itself. Missing or non- reciprocal annotations may be ignored by search engines. Hreflang can be implemented in three different ways. The first method is adding ` link rel="alternate"` tags to the `` section of the page. For example, an English page can be marked with ``. The second method is defining hreflang through HTTP Headers, especially for non-HTML files such as PDFs. The third method is specifying the alternative language and region versions of each URL in the XML sitemap. For multilingual and multi-regional structures, the `x-default` value can also be used. `x-default` is used to indicate a default page that does not target a specific language or region. For example, a global homepage, country selector page or general English page may be defined as `x-default`. This helps provide a suitable fallback page when the user’s language or region does not match any option in the hreflang set. Hreflang does not directly guarantee higher rankings. However, because it helps show the correct language and regional version to the right user, it can contribute indirectly to organic performance. Showing the wrong language version can lead to high bounce rates, low engagement and poor user experience. Hreflang is a technical signal that helps reduce these problems. Common hreflang mistakes include using incorrect language or country codes, missing reciprocal links, defining URLs that conflict with canonical tags, adding hreflang to redirected or non-indexable pages and marking inconsistent URL sets. For this reason, pages included in a hreflang setup should be indexable, canonical structure should be correct, URLs should be complete and accessible, and the implementation should be carefully validated. In summary, the **hreflang tag** is an important international SEO annotation that helps multilingual or multi-regional websites show the right page to the right user. A successful hreflang structure requires each language version to be served on a separate URL, valid language and region codes to be used, reciprocal annotations to be implemented, canonical structure to be set correctly and one of the HTML, HTTP Header or XML sitemap methods to be applied consistently. ## Discover it in the dictionary ### Geospatial Analysis Geospatial analysis is a method used to examine data through location, distance, area and geographical relationships.
