什么是关键事件？
A key event is an event that measures an action that's particularly important to the success of your business. When someone triggers the event by performing the action, the key event is recorded in Google Analytics and surfaced in your Google Analytics reports.
Any event you collect can become a key event. To measure a key event, create or identify an event that measures the action and then mark the event as a key event. After you mark the event as a key event, you can see how many users perform the action and evaluate marketing performance across all channels that lead users to perform the action.
The following flow shows how to mark an event as a key event. In short, if an event is important to your business's success, you can mark the event as a key event in Analytics.

生成关键事件报告
您可以使用 Google Analytics（分析）报告和探索来统计用户触发关键事件的次数，并将转化功劳分配给用户关键事件触发路径中的不同接触点。
查看关键事件数
许多 Google Analytics（分析）报告（例如“着陆页”报告和“用户获取情况”报告）都包含“关键事件”列。“关键事件”列会显示用户在您的网站或应用上触发关键事件的次数（按左侧的维度值细分）。
如需按特定关键事件精细过滤计数，您可以选择“所有事件”菜单，然后选择特定关键事件，以便查看用户触发该关键事件的次数。
如需进一步调查按任何兼容维度分列的关键事件数，您可以使用“关键事件”和“会话关键事件率”等关键事件指标构建自己的探索。
将功劳分配给接触点
在“广告”部分中，您可以使用“归因”和“路径”报告，将功劳分配给用户关键事件触发路径中的不同接触点，并了解不同的归因模型如何以不同的方式将功劳分配给这些接触点。详细了解广告报告
创建 Google Ads 转化
您可以根据关键事件创建 Google Ads 转化，以便关联

- Report on the same conversion counts between Google Ads and Analytics
- Bid against the conversions in your ad campaigns
- Build audiences for re-marketing purposes
