Canonical vs Hreflang Tag: When and How to Use Them in SEO?

In technical SEO, tags help search engines understand how your website pages should be indexed and shown in search results. Two important tags used for this purpose are the canonical and hreflang tags. Many website owners often get confused about the canonical vs hreflang tag and how they actually work in SEO.

The canonical and hreflang tag concept becomes very important when you have duplicate pages, similar content, or multiple language versions of a page. 

If these tags are used incorrectly, search engines may index the wrong page or show the wrong version to users.

Blog Objective

The main objective of this blog is to explain the canonical vs hreflang tag concept in simple and clear words. Many people get confused about when to use canonical tags and hreflang tags. After reading this guide, you will understand what canonical and hreflang tags are, the key difference between them, when to use each tag, and how to implement them correctly in SEO.

What Are Canonical Tags?

A canonical tag tells search engines which version of a page is the main or original page when multiple pages have similar or duplicate content.

For example, a product page may exist with different URLs like:

  • example.com/shoes
  • example.com/shoes?color=black
  • example.com/shoes?size=10

These pages show almost the same content. Search engines may treat them as duplicate pages. A canonical tag helps search engines understand which page should be indexed. If you have implemented canonical tags correctly but your pages are still not getting indexed, the issue could be related to crawl budget problems in Google Search Console (GSC).

Example of a canonical tag:

<link rel=”canonical” href=”https://example.com/shoes/”>

This tells search engines that the main version of the page is example.com/shoes.

Canonical tags help:

  • Avoid duplicate content issues
  • Improve SEO ranking signals
  • Consolidate link equity to one page

What Are Hreflang Tags?

An hreflang tag tells search engines which language or regional version of a page should be shown to users.

It is mostly used on international websites that target different countries or languages.

Example:

  • English version → example.com/en/
  • Spanish version → example.com/es/
  • French version → example.com/fr/

Example of hreflang tag:

1st: <link rel=”alternate” hreflang=”en” href=”https://example.com/en/”>

The above tag “en” tells search engines that this page is created for English-speaking users. It helps search engines show the English version of the page to people who search in the English language or are located in English-speaking regions.

2nd: <link rel=”alternate” hreflang=”es” href=”https://example.com/es/”>

The above tag “es” tells search engines that this page is created for Spanish users. It helps search engines show the Spanish version of the page to people who search in the Spanish language or are located in Spanish-speaking regions.

Hreflang tags help:

  • Show the correct language page to users
  • Avoid confusion between similar international pages
  • Improve international SEO performance
