What Is Indexing and How Canonical Tags Prevent Confusion

What is indexing and why are canonical tags important? Indexing is when search engines add your page to their database, but duplicate URLs can create confusion. Canonical tags help by telling search engines which version of a page is the main one. This prevents dilution of SEO and ensures the correct page gets indexed. If ignored, duplicate pages might get indexed instead, harming visibility. Proper use of canonical tags is essential in maintaining a clean, index-friendly site structure.
