This tip has been brought with version 2.4.2 of The SEO Framework.
Canonical URLs are the URLs that lead to exactly where a page is located. It’s very important for Search Engines to find the right page, to prevent duplicated content mistakes.
The Search Engine will therefore always follow the canonical URL and will most likely ignore the current page if the canonical URL points to a page other than the current page.
For this reason, the canonical URL within The SEO Framework will look for many variables before making one, with this update even more so.
This concludes that it’s advised not to touch the Custom Canonical URL unless you’re absolutely certain that Search Engines should look for another webpage.
