Hreflang

Hreflang is an HTML attribute that tells search engines which language and region a page targets, so the right version appears in the right country's results.

Hreflang is a tag you add to your pages to tell Google which language or regional version to show to which searcher.

What Hreflang Means in Marketing

When you run a website in multiple languages or target the same language across different regions, search engines face a problem: they do not know which version of your page to show to a user in France, or whether your Australian English page should outrank your UK English page for a British searcher.

Hreflang solves that by giving search engines an explicit map. You tell them: this page is for English speakers in India, that page is for English speakers in the US, and the French page is for French speakers in France. Google then shows the correct version based on the searcher’s location and browser language settings.

Without it, search engines guess. Sometimes they guess correctly. Often they do not, and the wrong version of your site ranks in a market you were trying to serve with a different page.

How Hreflang Works

The attribute sits in the head of each page or in your sitemap. The format is:

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

Key rules:

  • Language codes follow ISO 639-1 (en, fr, de). Region codes follow ISO 3166-1 alpha-2 (IN, US, GB).
  • x-default is the fallback shown when no region-specific version matches.
  • Self-referencing is required. Each page must include its own hreflang tag pointing to itself, plus tags for every other version in the set.
  • Reciprocal linking is required. If page A references page B, page B must reference page A.

Hreflang Example

A Kerala-based e-commerce brand expands to serve customers in the UAE and the UK. Their product pages exist in three versions: English for India (en-IN), English for the UAE (en-AE) and English for the UK (en-GB), each with different prices and shipping terms. Without hreflang, a UK searcher might land on the India-priced version and see incorrect delivery information. With correctly implemented hreflang tags, Google serves the right version automatically.

Why Hreflang Matters for Marketers

Hreflang errors are silent. They do not produce error messages in your analytics. They show up as unexplained bounce rates, international campaigns that underperform, or ranking signals split between two pages that should be one clear signal.

For any site serving more than one market or language, getting hreflang right is the kind of technical work that makes every other SEO effort more efficient.

Frequently Asked Questions

When do you need hreflang tags?

When you have the same content in multiple languages, or the same language targeted at different regions with meaningful differences in content. An English site that serves only one country does not need hreflang. A site with English pages for the US, UK and Australia, where the prices, spellings or references differ, does.

What happens if hreflang is implemented incorrectly?

Search engines may show the wrong language version to users, which increases bounce rate and signals irrelevance. They may also treat duplicate-language pages as content duplication and split ranking signals between them. Incorrect hreflang is usually worse than no hreflang, because it actively confuses the crawler.

Do hreflang tags need to be reciprocal?

Yes. Every page in the hreflang set must reference every other page in the set, including itself. If the English page references the French page but the French page does not reference the English page, search engines will ignore the tag. This self-referencing requirement is the most common implementation error.
