Duplicate without user-selected canonical

Hundreds of URLs in GSC fall under this section, and most of them are not creating value. How are you dealing with this? Are you checking each URL individually to decide which ones need canonical tags?

Use automated tools to crawl your site and categorize duplicates based on value and content similarity. Implement canonical tags, 301 redirects, or noindex tags as appropriate, and update internal links to point to preferred URLs.
