* **What is a Canonical Tag?** It's an HTML tag (``) that tells search engines which version of a page is the "master" version, helping to prevent duplicate content issues and consolidate ranking signals.
* **CORS Policy:** Browser security prevents direct fetching of content from most external websites via JavaScript. If "Fetch from URL" doesn't work, please use the "Paste Raw HTML" option.
* **SEO Best Practice:** Every page should ideally have a self-referencing canonical tag (pointing to its own preferred URL) or point to another page if it's a duplicate or very similar content. Missing or incorrect canonical tags can lead to SEO issues.
