Key concepts¶
Amplitude is an event-based analytics tool that tracks the behaviors of users based on in-product interactions and analyzes user behavior in real-time. Event-based analytics is the method of tracking and analyzing interactions between users and your product, also known as events. Before you get started with Amplitude, it's important to know the key concepts used in Amplitude.
| Name | Description | A music player app example |
|---|---|---|
| Events | An event is an action a user has taken | A user presses the "Play Song" button |
| Event Properties | Event properties are details about an event. | The genre of the music |
| Users | A user is the specific individual that interacts with your product | A user uses the app to play music |
| User Properties | User properties are details about a user | Whether a user is on a paid or free plan |
| Sessions | A session is the period of time a user has your app | A user uses the app to play music |
TL;DR: If you aren't interested in the details of these concepts you can stop reading now.
Events¶
Events are actions that users take in your product, such as clicking a button, making a purchase, or signing up for an account. You need to define which events you want to track in Amplitude, and what data you want to capture for each event. For example, you could send an “Play Song” event every time a user presses the Play button in a music player application.
You can learn more about how to track events and understand your users' actions.
Event properties¶
Event Properties are details about events. For example, when someone presses the “Play Song” event in a music player application, you can use event properties to track the genre. Any detail related to the event can be an event property.
Users¶
A user is the specific individual that completed an interaction with your product. Amplitude analyses depend on accurately tracking unique users. This is often trickier than it sounds, because your users can log in and out at will, browse anonymously, or use multiple devices.
You can learn more about how to identify your users and how Amplitude tracks unique users by using a combination of device IDs, user IDs, and Amplitude IDs.
User properties¶
User properties are details about users. For example, you could keep track of whether a user was on a paid or free plan in a music player application.
Sessions¶
A session is the period of time a user has your app in the foreground or has your website open. Sessions are a useful metric in Amplitude for understanding the frequency and duration of your users' engagement with your product. Amplitude assigns a session ID to each session, and all events within the same session share the same session ID. To send data, Amplitude SDKs automatically generate and manage session IDs. However, you have to manage session IDs yourself, you use HTTP APIs.
