New feature
Query string rule
You can now show a widget only on pages that have a certain query string value. For example, you can show a widget only on search pages where visitors search a certain term:
https://site.com/search?query=Sneakers

Note: This rule works differently from the targeting query string filter which is remembering the query strings across page views and sessions, whereas the widget rule is only referring to the current query string value on the current page.
