When does the Google Analytics tracking code send a pageview hit to Analytics?

The Google Analytics tracking code sends a pageview hit to Analytics primarily every time a user loads a webpage. This is the fundamental action that triggers a standard pageview, recording a visit to that specific page. While other interactions like clicking a video, adding items to a cart, or performing a search can be tracked, they require additional event tracking implementation. Without explicit event tracking, these actions do not automatically generate a pageview hit. Pageviews are the default and most common type of hit sent by the basic tracking code.
