Canonical Tag Definition: What It Means for Real Estate SEO

Quick definition: A canonical tag is an HTML element that tells Google which version of a page is the preferred one when duplicate or similar content exists across multiple URLs.

What it means

Canonical tags live in the page <head> as <link rel="canonical" href="..." />. They consolidate ranking signals from all duplicate or near-duplicate URLs onto the canonical URL.

Common canonical use cases include filtered IDX URLs, tracking parameters, paginated archives, and HTTP/HTTPS or www/non-www variations.

Why it matters for real estate SEO

Real estate sites with IDX integrations often generate hundreds of near-duplicate URLs from filters and sort parameters. Proper canonicalisation prevents keyword cannibalization and consolidates backlink equity.
