A canonical tag<\/a> is an HTML signal that tells search engines which URL is the preferred version of a page. When similar or duplicate content exists at more than one address, the canonical consolidates ranking signals onto the version you choose.<\/p>\n It looks like a small line in the page head, but it has a large effect on which URL ranks. Canonicals are a core part of technical SEO<\/a> and closely tied to indexability<\/a>. Google explains the options in its guide to consolidating duplicate URLs<\/a>.<\/p>\n Duplicate content is common and usually accidental. The same product appears under several category paths, a page loads with and without tracking parameters, or a printer-friendly version exists alongside the main one. Without a clear signal, search engines pick one version for you, and it may not be the one you want.<\/p>\n Canonicals let you consolidate that duplication so authority builds on a single URL instead of being split across several. That is often the difference between a page that ranks and one that stalls.<\/p>\n A canonical and a 301 redirect<\/a> both consolidate signals, but they are not the same.<\/p>\n Does a canonical tag guarantee which URL ranks?<\/strong> Should every page have a canonical tag?<\/strong> Part of our Technical SEO guide<\/a>.

Frequently asked questions<\/h2>\n
\nNo. It is a strong hint. Search engines usually honor it, but conflicting signals like internal links and sitemaps can lead them to choose a different canonical.<\/p>\n
\nYes. A self-referencing canonical on every page is good practice and prevents accidental duplication from parameters or variations.<\/p>\n
