For more information on canonical, see the following article:
3. Pages that do not require search traffic
We also recommend setting the noindex tag on pages that do not require search traffic, such as 404 error pages
and thank you pages. Error pages are necessary because they inform users that the target page does not exist. Similarly, thank you pages and pages to confirm the completion of a procedure are also necessary. However, none of germany phone number resource these pages need to be indexed.

4. Pages with little information
Pages with a clearly low amount of information, such as text and images, may be judged tobe low quality pages and may be a cause of negative evaluation. Therefore, measures such as setting the noindex tag and increasing the amount of information in the content are necessary.
For example, a page that says "There are 0 search results" that is displayed when there are no relevant products on an EC site falls into this category.

5. Copy content
If Google determines that your content is copied, you risk receiving a serious penalty, so be careful. If you have copied content from another site, consider whether you really need that content. If you don't need it, delete it.
If you do want to keep it, set the noindex tag to avoid penalties.
