🔖 What are Canonical Tags?
Canonical tags, also known as rel=canonical, are HTML elements used to prevent duplicate content issues by indicating the preferred version of a webpage when multiple versions with similar content exist.
⭐ Why are Canonical Tags Important in SEO?
Canonical tags play a critical role in SEO by consolidating duplicate content, ensuring search engines credit the right page with authority, and directing search engine crawlers to index the correct version of your content. This helps maintain the integrity of your site's ranking potential.
⚙️ How Do Canonical Tags Work?
- Identify pages with similar content that could cause duplication.
- Select the most valuable page as the canonical version.
- Add a canonical tag in the HTML head section of non-canonical pages, pointing to the canonical version.
