GA4 常用的event_name與parameters

 

Measurement option / event Triggered… Parameters

Page views

page_view

each time the page loads or the browser history state is changed by the active site

This event is collected automatically. You cannot turn off collection.

An advanced setting on this option controls whether the event is sent based on browser-history events. This measurement option listens for pushState, popState, and replaceState.

The event populates the Views metric. The parameters populate the following dimensions:

page_location (page URL), page_referrer (previous page URL)

Scrolls

scroll

the first time a user reaches the bottom of each page (i.e., when a 90% vertical depth becomes visible)

The event populates the Percent scrolled dimension.

No parameters are collected

Outbound clicks

click

each time a user clicks a link that leads away from the current domain

By default, outbound click events will occur for all links leading away from the current domain. Links to domains configured for cross-domain measurement will not trigger outbound click events.

The parameters populate the following dimensions:

link_classes, link_domain, link_id, link_url, outbound (boolean)

Site search

view_search_results

each time a user is presented with a search results page, as indicated by the presence of a URL query parameter

By default, the event is triggered based on the presence of one of the following 5 query parameters in the URL:

  • q
  • s
  • search
  • query
  • keyword

You can optionally configure this event to look for other URL query parameters.

The search_term parameter populates the Search term dimension.

search_term, optionally ‘q_<additional key=””>’ (where <additional key=””> matches an additional query parameter you specify to be collected under advanced settings).

Note: This event only sends the unique_search_term parameter when it has a value of 1 (i.e. when the string is unique to that session).

Video engagement

video_start

video_progress

video_complete

For embedded videos that have JS API support enabled, the following events are triggered:

  • video_start: when the video starts playing
  • video_progress: when the video progresses past 10%, 25%, 50%, and 75% duration time
  • video_complete: when the video ends

The parameters populate the following dimensions:

video_current_time, video_duration, video_percent, video_provider, video_title, video_url, visible (boolean)

File downloads

file_download

when a user clicks a link leading to a file (with a common file extension) of the following types:

  • document
  • text
  • executable
  • presentation
  • compressed file
  • video
  • audio

File extensions that match the following regex will trigger the event:

pdf|xlsx?|docx?|txt|rtf|csv|exe|key|pp(s|t|tx)|
7z|pkg|rar|gz|zip|avi|mov|mp4|mpe?g|wmv|midi?|mp3|wav|wma

The parameters populate the following dimensions:

file_extension, file_name, link_classes, link_domain, link_id, link_text, link_url

Form interactions

form_start

form_submit

‘form_start’: the first time a user interacts with a form in a session

‘form_submit’: when the user submits a form

You can use these two events to see how many users started to fill out a form and compare the information to users who submitted the form.

Note: You can only use the parameters in your reports if you create custom dimensions for them.

form_start

  • form_id: HTML id attribute of the <form> DOM element
  • form_name: HTML name attribute of the <form> DOM element
  • form_destination: URL to which the form is being submitted

form_submit

  • form_id: HTML id attribute of the <form> DOM element
  • form_name: HTML name attribute of the <form> DOM element
  • form_destination: URL to which the form is being submitted
  • form_submit_text: text of the submit button, if present
