What it does

Hreflang Generator creates correct hreflang tags for your multilingual or multi-regional website. It validates existing implementation, finds common errors, and generates the complete tag set.

The Problem

Hreflang tags are the most error-prone SEO element.

• Complex syntax with many pitfalls
• Missing return tags cause errors
• Wrong language codes break implementation

The Solution

Validated hreflang tags generated automatically.

• Generate correct tags for all pages
• Validate existing implementation
• Fix common errors

Features

• Tag Generation: Generate correct hreflang tags for all language versions.
• Validation: Validate existing hreflang implementation.

How it works

1. Paste in the hreflang tags you want to validate — ideally the sets from several pages at once
2. The tool reviews the tags against Google's guidelines and established practice
3. Get a report with errors, warnings and corrected hreflang tags ready for implementation

Use cases

• Nordic businesses with websites in Norwegian, Swedish, Danish and Finnish needing correct hreflang tags
• International companies expanding to Nordic markets needing proper language targeting
• Web developers implementing multilingual websites wanting to quality-check hreflang before launch

Why use Hreflang Validator?

Hreflang is one of the fiddliest technical SEO implementations, and errors are common. For Nordic websites the problem is extra noticeable because the Nordic languages sit so close that Google easily conflates them. A Norwegian page may be shown to Swedish users, or a Danish page to Norwegians — weakening both user experience and rankings.

Hreflang Validator makes it faster to find and fix the errors. You paste in the tags — ideally the sets from several pages at once — and get a prioritized list of the issues with concrete solutions, plus corrected tags you can copy straight into the code. The tool fetches no pages itself, so what you paste in is what gets reviewed.

For Nordic businesses, correct hreflang tags are especially critical because many operate in 3-5 Nordic markets simultaneously. With Norwegian (Bokmål and Nynorsk), Swedish, Danish, Finnish and Icelandic — plus English — the setup quickly gets hard to keep track of. A systematic review of the tags is often what separates a setup that works from one that quietly sends users the wrong way.

What is hreflang and why is it important?

Hreflang is an HTML attribute that tells Google which language and region version of a page to show users in different countries. Without hreflang, Google may show the English version to Norwegian users, or the Swedish version to Danish users. For Nordic websites hreflang matters especially because the languages are so similar that Google often conflates them.

What's the difference between nb and no in hreflang?

This is one of the most common mistakes for Norwegian websites. "no" is the general code for Norwegian, while "nb" is specifically for Bokmål and "nn" for Nynorsk. Google accepts both "no" and "nb", but established practice is to use "nb" for Bokmål and "nn" for Nynorsk. If you have both written forms, you must use the specific codes. The tool checks that the codes you use fit the situation you describe.

Do all pages need hreflang tags?

Yes — every page that has a corresponding version in another language must have hreflang tags. That includes the homepage, content pages, product pages and category pages. Pages that only exist in one language don't need hreflang. A common mistake is to add hreflang only to the homepage and forget the rest.

Can the tool find the pages that are missing tags?

No. The tool does not crawl your site and fetches no pages — it only sees the tags you paste in. To find pages without hreflang you need a crawler or Search Console. The tool exists to check and correct the tags you already have.

What is x-default and do I need it?

X-default is a special hreflang value pointing to the fallback page — the version Google should show when the user's language doesn't match any of the specified language versions. For most Nordic websites, x-default should point to the English version. Without x-default, Google may choose an arbitrary language version for users outside your target markets.
