Larger websites operating in multiple languages and regions would need hreflang tags to effectively communicate language and regional focus to search engines like Google. These tags help to realize that a user is being redirected to the correct equivalent version of the page, depending on the language and geographical location settings. In this article, we will examine this topic in more detail: what are hreflang tags, and how can their utilization be effective according to modern SEO trends?
What is Hreflang?
Hreflang is an HTML attribute that indicates the type of web page and, optionally, the country of that language. This allows search engines to know that the same page is available in other languages or locations so that people can be given the right one to view.
Purpose of Hreflang Tags
Hreflang Tags are very important in online marketing. Hreflang tags serve several key purposes:
- Language and Region Targeting: These help define the language and locality of the page version that should be displayed to a search engine user.
- Avoid Duplicate Content Issues: With hreflang tags, page copies are pointed out as designed for different audiences, which helps us avoid treating such copies as duplicates.
- Enhance User Experience: More interaction is always achieved since the audience feels connected to the content written in their language and location, thus enhancing the likelihood of the conversion rate.
Implementing Hreflang Tags for Multilingual Websites
Using hreflang tags for websites in multiple languages is important for informing Google about language and region targeting. This assists in rerouting the users to the appropriate version of your webpage, depending on their language and location. Here are the steps and methods to implement hreflang tags effectively for multilingual websites:
Methods of Implementation
There are three primary methods to implement hreflang tags:
1. In the HTML Head
It is possible to insert hreflang tags into the HTML code right into every webpage’s <head> section. This method is very simple and effective, and in this way, we know that the tags will always be loaded when the page is loaded.
<head>
<link rel=”alternate” hreflang=”en” href=”https://example.com/en/page1″>
<link rel=”alternate” hreflang=”de” href=”https://example.com/de/page1″>
</head>
2. In the XML Sitemap
According to the testing results, bigger sites should also consider implementing hreflang annotations in the XML sitemap since they are more effective. The management of multiple pages and their alternations becomes easier through this method.
<url>
<loc>https://example.com/en/page1</loc>
<xhtml:link rel=”alternate” hreflang=”de” href=”https://example.com/de/page1″/>
</url>
3. In the HTTP Header
For any other type of file, meaning a file other than an HTML file, such as a PDF file, you can use the HTTP header to point to reflang tags.
Link: <https://example.com/de/page1>; rel=”alternate” hreflang=”de”
Using Multilingual Plugins
It is easy for websites developed based on platforms such as WordPress to implement hreflang tags using multilingual plugins. There are plugins, for instance, MultilingualPress and TranslatePress, which create hreflang tags whenever you are developing new language versions of the site.
Best Practices for Hreflang Implementation
1. Bidirectional Links
Out of the two, hreflang tags must be two-way tags. If an English page links to a German one, the German page has to link back to this English page. This helps websites teach search engines about pages related to the website or blogs.
2. Self-Referential Tags
Every page should include an hreflang attribute that points to the same page. This is useful to search engines, as it ensures that you own the primary and substitute structures of the webpage.
3. Use of X-Default Tags
The tag x-default is used when no translated variant suitable for a given user exists to provide a general landing page or an appropriate page variant. Although Google does not strictly require this, it is encouraged so that when the user’s language or country is not detected, they are taken to a relevant page.
<link rel=”alternate” hreflang=”x-default” href=”https://example.com/”>
4. ISO Codes for Country and Language
Specifically, the regions should reflect the ISO 639-1 language codes and ISO 3166-1 alpha-2 country codes. For example, “en-US” is for users located in the USA with an English language preference, “de-DE” is for users in Germany with a German language preference, and “zh-CN” is for users in China with a Chinese language preference.
5. AI for Hreflang
AI can also be used to auto-optimize the implementation of hreflang tags. AI tools can analyze your site structure and content and recommend the right language and region targeting strategy. Also, using AI technologies for hreflang generation and management is easier if you work with a massive website containing hundreds or thousands of pages with language versions.
6. Hreflang and SEO
Using hreflang tags for international SEO is crucial because these tags assist search engines in identifying how your bilingual or bi-continental site is organized. When used correctly, hreflang tags recommend your website to the search results for other languages and regions, increasing your presence and site visits internationally.
7. Canonical and Hreflang Tags Together
When using both the canonical version and hreflang tags to overcome duplicate penalties, they must not overlap. The canonical tag must point to the page’s desired version, whereas hreflang tags indicate the available linguistically or geographically different versions of the page.
<link rel=”canonical” href=”https://example.com/en/page1″>
<link rel=”alternate” hreflang=”de” href=”https://example.com/de/page1″>

Hreflang Sitemap Purpose
A sitemap with hreflang annotations is a single resource that allows you to describe a site’s language and regional versions and control these changes. This makes hreflang management and update implementation much easier, particularly on big sites. When people use hreflang tags correctly in their sitemaps, they ensure that search engines can easily crawl all the content versions.

Hreflang Tags and International SEO
Hreflang tags are part of global SEO best practices. They help Google distinguish a page’s language and geographical targeting. These tags are useful for websites, available in more than one language and/or country because they allow you to define which language and country the site visitor is located in, directing them to the proper version of the page.
What are Hreflang Tags?
Hreflang tags are HTML attributes that indicate the language of a webpage and, optionally, the region of the given web page. They consist of three main components:
- rel=”alternate”: Shows that the link leads to a different version of the content.
- hreflang: Lists the language and the country or any region (For instance, ‘en’ stands for English, ‘US’ stands for United States).
- href: It stores the URL of the other page, which will be shown when the error occurs.
For example:
<link rel=”alternate” hreflang=”en-US” href=”https://example.com/en-us/page1″>
Impact on International SEO
Hreflang tags have several key impacts on international SEO:
- Serve the Correct Version: They help the search engine provide the right version of a page to the user, depending on the language they use. For example, a user selected French language will be directed to the French version of the page, and vice versa for English, etc.
- Avoid Duplicate Content Issues: When used to specify which version of a page is intended for a particular language or geographical location, hreflang tags prevent duplication consequences. This is especially critical when it comes to issues of search engine optimization on your site.
- Improve User Experience: Your audience is more likely to be interested in content written in the language they understand and oriented to their region. This can increase dwell time, provide lower bounce rates, and consequently increase conversion rates.
- Enhance Search Engine Rankings: One basic strategy you should focus on when selecting your target languages and areas is that, for the latter, your site will rank higher in local search results because it will be more relevant to what the user is seeking.
Best Practices for Implementation
- Bidirectional Links: Ensure that all page versions link back to each other. For example, if an English page is linked to a French page, the French page should link to the English page.
- Self-Referential Tags: Add a hreflang point for each page to ensure you own both the primary and the duplicate page.
- Use of X-Default Tags: Establish a fallback page for users where no other language version can be provided by using the tag x-default.
Conclusion
Hreflang tags, as you have seen, are a great way to control your website’s international SEO. When using these tags properly, you can guarantee that your content will be delivered to users who understand your language and location preferences. Whether in Germany using the “de-DE” code or in China using the “zh-CN” code, hreflang helps you change content to address users from different countries. Fortunately, with the help of AI and appropriate tools, the interaction with hreflang tags becomes rather effective, supporting a strong International SEO approach.
