FAQ

What is a canonical URL?

A canonical URL is the preferred version of a webpage specified via a rel="canonical" tag. It tells search engines which URL to index when duplicate or similar pages exist.

Why are canonical tags important for SEO?

Canonical tags prevent duplicate content issues by consolidating link equity to one preferred URL. Without them, search engines may split ranking signals across multiple URLs.

Can this tool check any URL?

Due to browser CORS restrictions, client-side checking has limitations. The tool uses a public proxy for fetching. For comprehensive audits, complement with server-side crawlers.
