Understanding what hreflang tags are is important for websites that serve visitors in different languages or countries. When a business publishes multiple versions of the same content, search engines need to understand which page is intended for each audience.
For example, an online store may have separate English pages for customers in the United States and the United Kingdom. Although both pages use English, their currencies, shipping details, and regional information may differ.
In this situation, hreflang annotations help Google identify the relationship between these pages. As a result, search engines can better understand which language or regional version may be appropriate for users.
However, hreflang is not a direct ranking boost. Instead, it provides information about alternate pages and their intended audiences.
This guide explains how hreflang tags work, when to use them, and how to avoid common implementation mistakes.
What Are Hreflang Tags in SEO?
Hreflang tags are HTML link annotations that identify alternate versions of a webpage intended for different languages or geographical regions.
For instance, a company may publish its services in English, French, and German.
Although these pages describe similar services, each version is designed for a different language audience.
Therefore, hreflang annotations help Google understand that the pages belong to the same group of international alternatives.
Hreflang Tag Example
A basic implementation might look like this:
<link rel="alternate" hreflang="en-US" href="https://example.com/us/" />
<link rel="alternate" hreflang="en-GB" href="https://example.com/uk/" />
<link rel="alternate" hreflang="de" href="https://example.com/de/" />In this example, en-US identifies the American English version.
Meanwhile, en-GB identifies the British English version, and de represents the German-language page.
Importantly, these annotations do not automatically redirect visitors. Instead, they help Google understand the intended language and regional relationships.
How Do Hreflang Tags Work?
Hreflang annotations connect equivalent pages that serve different languages or regions.
For example, imagine an international retailer with three versions of the same product page:
- US English:
https://example.com/us/shoes/ - UK English:
https://example.com/uk/shoes/ - German:
https://example.com/de/schuhe/
Each page provides similar product information. However, the regional versions may contain different currencies, delivery options, or translated descriptions.
By implementing hreflang correctly, the retailer identifies these URLs as alternate versions.
Consequently, Google receives clearer information about the intended audience for each page.
Why Reciprocal Hreflang Tags Matter
Hreflang relationships should work in both directions.
For instance, if the US page references the German version, the German page should also reference the US version.
Additionally, each page should include its own URL within the alternate group.
Otherwise, incomplete relationships may prevent Google from using the annotations as intended.
Does Hreflang Automatically Redirect Visitors?
No. Hreflang does not control browser redirects.
Instead, it helps Google understand which alternate URL may be suitable for a search user.
Therefore, websites should provide accessible language navigation rather than relying on hreflang to move visitors between pages.
When Should You Use Hreflang Tags?
Hreflang is particularly useful for multilingual and multiregional websites.
However, not every website needs these annotations.
1. Websites With Multiple Languages
A website offering English, French, and German versions of the same content can use hreflang to identify those alternatives.
For example, a software company may publish translated pricing and product pages.
As a result, search engines can better understand the relationship between the translated URLs.
2. Country-Specific Websites
Some businesses publish separate pages for customers in different countries.
For instance, an ecommerce website may offer dedicated versions for the United States, United Kingdom, and Australia.
Although the pages may share the same language, their regional details can differ.
Therefore, hreflang can help identify the intended country-specific alternatives.
3. International Service Pages
Global service providers often maintain localized landing pages.
For example, a consulting company might offer English, Spanish, and German versions of its services.
In this situation, hreflang can connect the corresponding pages.
4. Multilingual Blogs
Blogs publishing translated versions of articles can also benefit from hreflang.
However, the linked articles should represent equivalent content rather than unrelated topics.
How to Generate Hreflang Tags
Generating hreflang markup does not require writing every HTML annotation manually.
Instead, you can prepare the relevant URLs and use a generator to create the code.
Step 1: Identify Alternate URLs
First, list the pages that represent the same content in different languages or regions.
For example, collect the English, French, and German versions of a service page.
Additionally, confirm that each URL loads correctly.
Step 2: Choose Language and Region Codes
Next, assign an appropriate hreflang value to each page.
Common examples include:
en— Englishen-US— English for the United Statesen-GB— English for the United Kingdomfr— Frenchde— Germanes— Spanish
Remember that a language code alone can be sufficient when country-specific targeting is unnecessary.
Step 3: Use the Degates Hreflang Generator
Once your URL list is ready, open the Degates Free Hreflang Tag Generator.
Enter the alternate URLs and their corresponding language or regional values.
Afterward, generate the markup and review the output carefully.
Step 4: Implement the Tags
For HTML implementation, place the alternate link annotations inside the webpage’s <head> section.
Alternatively, Google supports hreflang annotations through XML sitemaps and HTTP headers.
However, you do not need to implement the same relationships through all three methods.
Step 5: Test the Implementation
Finally, inspect the live website to confirm that the annotations are correct.
Check language codes, reciprocal references, destination URLs, and canonical settings.

Common Hreflang Implementation Problems
Even a small configuration error can make international SEO more difficult.
Therefore, review the following problems before publishing your annotations.
Missing Return Tags
Return tags are reciprocal references between alternate pages.
For example, if page A references page B, page B should also reference page A.
Otherwise, Google may ignore the incomplete relationship.
Incorrect Language Codes
Using unsupported language or regional values can cause implementation problems.
For instance, en-GB is the correct format for British English targeting, not en-UK.
Therefore, verify language and regional codes before adding them to your website.
Conflicting Canonical Tags
Canonical tags identify preferred URLs among duplicate or similar pages.
Meanwhile, hreflang identifies language or regional alternatives.
Consequently, conflicting canonical settings may interfere with the intended international page relationships.

Incomplete Alternate Groups
Every relevant page should consistently identify the alternate URLs within its group, including itself.
However, some websites update only one language version when adding new translations.
As a result, the hreflang relationships become incomplete.
Broken or Redirecting URLs
Hreflang annotations should reference valid destination URLs.
For example, outdated links may remain after a website migration.
Therefore, review the final URLs whenever your website structure changes.

Hreflang Tags vs Canonical Tags
Although both annotations help search engines interpret URLs, they serve different purposes.
| Feature | Hreflang Tags | Canonical Tags |
|---|---|---|
| Main purpose | Identify language or regional alternatives | Identify preferred URLs |
| Typical use | International SEO | Duplicate URL management |
| HTML attribute | rel="alternate" | rel="canonical" |
| Example | US and UK versions | Clean and parameterized URLs |
| Direct ranking boost | No | No guaranteed ranking boost |
For example, an international retailer may use hreflang to connect its US and UK product pages.
Meanwhile, canonical tags can identify preferred URLs when tracking parameters create duplicate versions.
Therefore, both annotations may be necessary on the same international website.
How to Check Hreflang Tags
After implementing hreflang, verify the published markup.
Inspect the Page Source
Open the relevant page and view its HTML source.
Then search for hreflang to locate the alternate annotations.
Check Reciprocal References
Review the corresponding language or regional pages.
If one page references another, confirm that the reverse relationship is also present.
Verify Destination URLs
Check whether each alternate URL loads successfully.
Additionally, review redirects and broken links.
Review Canonical Settings
Make sure canonical annotations are consistent with the intended indexing of the alternate pages.
For example, regional pages intended to remain independently indexable should not unintentionally canonicalize to an unrelated country version.
Monitor Google Search Console
Google Search Console can help you monitor indexing and search performance.
However, it does not provide a comprehensive dedicated hreflang validation report.
Therefore, manual technical checks remain important.
