32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Event Segmentation
- A chart type that counts or filters events over time, split by properties, to show how often an action occurs and by whom.
- Active User Definition
- A user who performs at least one tracked event within the selected date range, regardless of whether they were new or returning.
- Retention Cohort
- A group of users who first performed a start event in a period; retention measures how many return to a return event in later periods.
- Funnel Conversion Window
- The maximum time allowed between the first and last funnel step for a user to count as converted; steps must occur within it.
- User vs Event Property
- A user property is stored once per user and can be overwritten; an event property is attached to a single event occurrence.
- Formula Metric
- An arithmetic combination of events or metrics, such as A divided by B, used to compute rates directly in a chart.
- Group-By Property
- Splits a chart into separate series by a chosen event or user property value, enabling comparison across segments.
- Amplitude ID
- The internal identifier Amplitude assigns to a user profile; events from User ID and Device ID are stitched to it.
- Identity Merge
- The process of linking a Device ID and User ID to one Amplitude ID, combining their events into a single user timeline.
- Tracking Plan
- A governed schema of expected event types and property values used to validate incoming data and flag unexpected events.
- Cohort Sync
- Exporting a defined user cohort to a destination like an ad platform or warehouse, refreshed on a configured schedule.
- Event Streaming Export
- A continuous export of raw events to a warehouse or cloud storage destination, including identifiers and timestamps.
- User Deletion API
- An endpoint that erases a user's data from Amplitude to satisfy privacy regulations such as GDPR or CCPA erasure requests.
- Feature Flag Rule
- A targeting condition evaluated per user; the first matching rule determines the variant, with a default fallback.
- Deterministic Bucketing
- Assigning users to variants via a hash of an identifier, so the same user consistently receives the same variant.
- Exposure Event
- The event fired when a user actually sees a treatment; it defines experiment assignment and separates intent from treatment.
- Mutual Exclusion Group
- A configuration ensuring a user is assigned to at most one experiment within a group, preventing conflicting treatments.
- Holdout
- A subset of users withheld from treatment across multiple experiments to measure cumulative long-term impact.
- Primary Metric
- The pre-declared outcome measure an experiment is designed to detect a change in; significance is judged against it.
- Session Timeout
- The inactivity gap that ends a session; by default 30 minutes, after which a new session begins for the user.
- Replay Masking
- A privacy setting that hides text in captured replays, either globally or for specific elements selected by CSS selector.
- Replay Sampling
- Recording only a percentage of sessions, which reduces storage cost but means not every session has an available replay.
- User Timeline
- A chronological view of a single user's events that links to associated session replays for debugging behavior.
- Console Log Capture
- Recording browser console output alongside a replay to help diagnose errors that occurred during the recorded session.
- Click Heatmap
- An aggregated visualization of where users click or tap on a page, highlighting high- and low-interaction areas.
- Rage Click
- Repeated rapid clicks in a small area, indicating user frustration with an unresponsive or confusing element.
- Scroll Depth
- The maximum scroll position reached per session on a page, aggregated to show how far users typically view content.
- Dead Click
- A click on an element that is not interactive, revealing where users expect functionality that does not exist.
- Element vs Coordinate Heatmap
- Element heatmaps attribute activity to a DOM element; coordinate heatmaps show raw position on the rendered page.
- Guide Targeting
- Rules using user properties, cohorts, and trigger events that determine which users see an in-product guide and when.
- NPS Scoring
- A survey metric where respondents rate 0-10; promoters are 9-10, passives 7-8, detractors 0-6, and NPS is promoters minus detractors.
- Guide Frequency Cap
- A throttle limiting how often the same guide or survey is shown to a user to avoid over-messaging.
