Widget visibility can be configured under individual widget settings under “Appearance → Widgets” in your WordPress administration area or through the widget editing interface in the Customizer.
TARGET BY URL
The “Target by URL” is a powerful feature for targeting sections of your website based on the request URLs. It was inspired by a similar feature in the Drupal CMS.
Use relative URLs such as page/sub-page instead of absolute URLs http://example.com/page/sub-page because relative URLs are more flexible and make the logic portable between different domains and server environments.
Use the wildcard symbol * for matching dynamic parts of the URL. For example:
topic/widgets/* to match all posts in the widgets category, if your permalink structure is set to /topic/%category%/%postname%.
page-slug/* to match all child pages of the page-slug parent page.
Use a trailing ?* to capture URL with all query arguments such as utm_source, etc. For example, for every blog/post-slug also include blog/post-slug?*.
EXCLUDE BY URL
Specify URLs to ignore even if they’re matched by any of the other context rules. For example, enter example/sub-page to hide a widget on this page even when “All Posts” is selected under “Global Sections”.
