What is a Canonical Tag?

A canonical tag is an HTML element that tells search engines which URL represents the master version of a page.

Canonical tags help prevent duplicate content issues by consolidating ranking signals to the preferred URL.

Example:

When multiple URLs contain similar or identical content, a canonical tag helps search engines understand which page should appear in search results.

Why Are Canonical Tags Important for SEO?

Canonical tags play a critical role in technical SEO and website indexing.

Benefits include:

Prevent duplicate content issues
Consolidate ranking signals
Improve crawl efficiency
Preserve link equity
