Canonical tag

Canonical Tag for Ecommerce SEO

A canonical tag tells search engines which URL is the preferred version when products, variants, filters, and tracking parameters create duplicates.

Why it matters

Ecommerce stores often create duplicate URLs through collections, filters, variants, sort parameters, and tracking links. Canonical tags help consolidate signals to the preferred URL.

Common mistake

The most common mistake is allowing multiple apps, themes, or plugins to output conflicting canonicals on the same page.

Should product pages have canonicals?

Usually yes. Most product pages should canonicalize to their preferred clean URL unless a specific duplicate strategy exists.
