What is Canonical Issue in SEO?

Hii Priya,

A canonical issue in SEO occurs when multiple pages on a website have similar or duplicate content, causing confusion for search engines about which page to rank. This can lead to lower rankings or diluted page authority. The canonical tag is used to indicate the preferred version of a page, directing search engines to index only that version. Resolving canonical issues ensures proper content indexing, prevents duplicate content penalties, and helps maintain strong SEO performance across a website.

A canonical issue in SEO arises when multiple URLs display identical or very similar content, causing search engines to struggle in determining which version to index or rank. This often results from technical factors like duplicate pages, dynamic URL parameters, or inconsistent internal linking. For example, a website's homepage might be accessible via www.example.com, example.com, and www.example.com/index.html, all displaying the same content. Such duplication can dilute ranking signals like backlinks and hinder SEO efforts. To resolve this, webmasters use the canonical tag (rel="canonical") to specify the preferred URL, helping search engines focus on the intended version and consolidate ranking signals effectively.
