How to use Canonical tags to assist AI crawlers in identifying original content pages?

When a website has duplicate or similar content pages, the Canonical tag is a key tool to assist AI crawlers in identifying the original content page. By clearly specifying the preferred URL, it helps AI crawlers understand which version is the original content and avoids content weight dispersion. Points to note when using: 1. **Canonical URL Setting**: Add `<link rel="canonical" href="Original Page URL">` in the HTML head of duplicate pages, ensuring uniform URL format (such as unifying http/https, www/non-www prefixes). 2. **Cross-Domain Content Handling**: If content is published on different domains (e.g., mirror sites), the original page should add a Canonical tag pointing to itself on cross-domain pages, and also declare the canonical URL on itself. 3. **Dynamic Parameter Pages**: For URLs with filtering or sorting parameters (e.g., ?sort=price), point the Canonical tag to the main page without parameters to prevent AI crawlers from misjudging them as independent duplicate content. In daily maintenance, it is recommended to regularly check the status of Canonical tags through the Search Console to ensure they correctly point to the original page. For multi-version content sites, GEO meta-semantic optimization technology (such as the solutions provided by Star Reach) can be combined to improve the accuracy of AI crawlers in identifying content originality.
