No, an event parameter is not a hit in GA4. An event parameter is a piece of information that provides more details about an event. For example, if the event name is page_view, the event parameters can include page_title, page_location, and page_referrer. An event parameter is not a hit by itself, but it is part of a hit. A hit in GA4 is an event that represents an interaction that a user has on your website or app. Every hit in GA4 has a name and up to 25 parameters that can provide additional information about the hit.

To illustrate this difference, let’s look at an example of a hit and its parameters in GA4:

{
  "event_name": "page_view",
  "event_params": [
    {
      "key": "page_title",
      "value": {
        "string_value": "Home"
      }
    },
    {
      "key": "page_location",
      "value": {
        "string_value": "https://example.com/"
      }
    },
    {
      "key": "page_referrer",
      "value": {
        "string_value": "https://google.com/"
      }
    }
  ]
}

In this example, the hit is the page_view event, which indicates that a user viewed a page on your website. The parameters are page_title, page_location, and page_referrer, which provide more information about the page that was viewed. The parameters are not hits by themselves, but they are part of the hit.

I hope this helps you understand the difference between a hit and an event parameter in GA4.
