Hreflang Generator — Create Correct International SEO Tags Instantly

International SEO without hreflang is guesswork

You have a website serving users in multiple languages or countries. Without proper configuration, Google might serve your English content to French speakers, your German pages to American users, or rank your regional variant in the wrong country. Hreflang tags fix this — they explicitly tell search engines which version of a page is intended for which language and region.

Getting hreflang right is notoriously fiddly. The tags must be bidirectional, self-referencing, and syntactically precise. A hreflang generator handles the tag construction so you can focus on making sure the right content goes in front of the right audience.

What Hreflang Tags Are

Hreflang tags are <link> elements in the <head> section of a page (or in the XML sitemap) that specify language and geographic targeting:

<link rel="alternate" hreflang="en" href="https://example.com/page" />
<link rel="alternate" hreflang="fr" href="https://example.com/fr/page" />
<link rel="alternate" hreflang="de" href="https://example.com/de/page" />
<link rel="alternate" hreflang="x-default" href="https://example.com/page" />

Each hreflang attribute specifies the language code (and optionally the region), and each href points to the version intended for that audience.

Hreflang Language and Region Codes

Hreflang uses ISO 639-1 language codes and ISO 3166-1 alpha-2 region codes:

Language only:

en — English (any region)
fr — French (any region)
de — German (any region)
zh — Chinese (any script/region)
bn — Bengali
ar — Arabic

Language + region (for targeting specific countries):

en-US — English for US users
en-GB — English for UK users
en-AU — English for Australian users
fr-FR — French for France
fr-CA — French for Canada
zh-CN — Chinese (Simplified) for China
zh-TW — Chinese (Traditional) for Taiwan
pt-BR — Portuguese for Brazil
pt-PT — Portuguese for Portugal

x-default: A fallback for users whose language/region doesn't match any specific hreflang — typically points to the homepage or an international/English version.

The Rules Hreflang Must Follow

Hreflang implementation has strict requirements. Getting any of these wrong causes the tags to be ignored:

1. Bidirectional — every page must reference all its alternatives, including itself.

If en page references fr, the fr page must also reference en and itself. If any direction is missing, Google ignores the entire set.

2. Self-referential — every page references itself.

The English page must include a hreflang pointing to its own URL.

3. Absolute URLs — no relative URLs in hreflang attributes.

4. Valid language/region codes — use ISO 639-1 and ISO 3166-1 codes exactly.

5. All URLs in the set must return 200 status — no redirects, no 404s.

How to Use the Hreflang Generator on sadiqbd.com

Enter each URL and its language/region target — add one row per language variant
Add x-default — specify the fallback URL
Generate — the tool produces the complete set of hreflang tags for each page

The generator ensures bidirectionality and self-referencing — so all you need to do is add the correct set to each respective page.

Real-World Examples

English + French website

You have:

https://example.com/about — English version
https://example.com/fr/about — French version

Tags for the English page (/about):

<link rel="alternate" hreflang="en" href="https://example.com/about" />
<link rel="alternate" hreflang="fr" href="https://example.com/fr/about" />
<link rel="alternate" hreflang="x-default" href="https://example.com/about" />

Tags for the French page (/fr/about) — must be identical in structure:

<link rel="alternate" hreflang="en" href="https://example.com/about" />
<link rel="alternate" hreflang="fr" href="https://example.com/fr/about" />
<link rel="alternate" hreflang="x-default" href="https://example.com/about" />

Both pages carry the full set of hreflang tags — that's the bidirectionality requirement.

UK vs. US English

Same language, different content (prices in pounds vs. dollars, localised terminology):

<link rel="alternate" hreflang="en-GB" href="https://example.com/uk/pricing" />
<link rel="alternate" hreflang="en-US" href="https://example.com/us/pricing" />
<link rel="alternate" hreflang="x-default" href="https://example.com/pricing" />

Without these tags, Google might serve the UK pricing page to US users — confusing currency and irrelevant terms.

Multi-language e-commerce

A store with 5 language versions (EN, FR, DE, ES, PT) has hundreds of product pages. Each product page needs hreflang tags for all 5 versions. The generator creates the tag set once; the CMS inserts the correct URLs programmatically for each page.

x-default for an international landing page

Your homepage at https://example.com serves a language-selection page. Use x-default to designate it as the fallback:

<link rel="alternate" hreflang="x-default" href="https://example.com" />
<link rel="alternate" hreflang="en" href="https://example.com/en" />
<link rel="alternate" hreflang="fr" href="https://example.com/fr" />

Hreflang in XML Sitemaps vs. HTML

Hreflang tags can be implemented in two places — choose one, not both:

HTML <head> tags — easier to manage for small sites; each page carries its own tags.

XML sitemap — more practical for large sites (hundreds or thousands of pages). The sitemap lists each URL with its hreflang set in a structured format. Changes can be made in one file rather than across thousands of pages.

For most small-to-medium sites, HTML implementation is simpler. For large-scale international sites, sitemap implementation is more manageable.

Common Hreflang Mistakes

Missing self-referential tag. Each page must reference itself. Omitting this causes the entire hreflang set to be treated as invalid.

Unidirectional tags. If page A references page B but page B doesn't reference page A, the connection is broken. Both pages must reference each other.

Wrong language codes. en-uk is wrong (should be en-GB). cn is wrong (should be zh-CN). Language codes are case-insensitive but must be valid ISO codes.

Missing x-default. Not required but strongly recommended. Without it, users whose language isn't in the set get an arbitrary page.

Hreflang on 404 or redirect URLs. All hreflang URLs must resolve to 200 OK responses with the actual content.

Verifying Hreflang Implementation

After deploying hreflang tags:

Google Search Console → International Targeting → Language section shows hreflang errors detected across the site
URL Inspection tool → checks individual pages for detected hreflang tags
Screaming Frog → crawls and audits hreflang across all pages, flags orphaned and incomplete sets
Manual source view → check the rendered <head> HTML for a few pages in each language

Frequently Asked Questions

Do I need hreflang if I only translate the UI but keep the same content? If the core content is the same language, hreflang isn't needed. Hreflang is for different language or regional versions of the same content — not just translated navigation menus.

Does hreflang affect rankings in the target country? Hreflang doesn't directly boost rankings — it helps ensure the right page is served to the right user. The correct page in front of the right audience naturally performs better (lower bounce rate, higher engagement), which indirectly benefits rankings.

What if I don't have translations for every page? Only add hreflang to pages that have translations. Don't point hreflang at untranslated pages — it's better to omit the tag for that language than to point to the wrong content.

Can hreflang cause penalties? No — hreflang errors cause the tags to be ignored (the pages are treated as if no hreflang exists), not penalised. Incorrect implementation wastes the opportunity; it doesn't actively harm the site.

Is the hreflang generator free? Yes — completely free, no sign-up needed.

International SEO without hreflang is like publishing a multi-language site and hoping Google figures out the targeting. The generator makes the tag construction precise and fast — the hard part is making sure your translated content is actually good.
