Canonicalization is a process that search engines need to understand in order for SEO functions. Duplicate content is a common issue online, but specifying which URL should be indexed as the “preferred” version can help avoid this problem and dilute rankings. Another way to consolidate URL variations is through canonicalization; if there are multiple URLs for one page or site section, then search engines must know which URL should be treated as the primary one. This also helps establish whether visitors should see pages with or without www in front of them – either way, they’ll still end up at what you’ve designated as your main domain.
