At a glance

Top 10 Events by Volume ranks your most frequently fired Amplitude events over the window, from the highest count down. It is the quickest way to see what your tracking is actually capturing and in what proportion: page views and session starts usually dominate, with add-to-cart, checkout, and purchase further down the list. Merchants use this card both to confirm the right events are present in the expected order and to spot anomalies, like a core commerce event sliding down the ranking or a rogue event suddenly appearing near the top.

Calculation

Top 10 Events by Volume counts every tracked event by type over the window and returns the ten with the highest totals, ranked in descending order. Counts are raw event totals with no per-user deduplication, so a single heavily active user can lift an event’s rank. Vortex IQ reads this from the Amplitude integration for the current window. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

Worked example

A representative reading of Top 10 Events by Volume for a typical merchant on Amplitude. Imagine the list reads, in order: Page Viewed at 620,000, Session Start at 410,000, Product Viewed at 180,000, Add to Cart at 52,000, Begin Checkout at 21,000, and Purchase at 9,000, followed by a few custom events. That shape is healthy: a wide top funnel narrowing toward purchase. Now suppose next month Add to Cart slips below a newly appeared event called “promo_modal_view” that wasn’t in last month’s list. That reordering is worth a look, it may mean a new popup is firing aggressively while the add-to-cart event lost coverage on a template. Vortex Mind compares the ranking against the prior period to flag which events rose, fell, or are brand new, and Ask Viq lets you ask, in plain English, “which events changed rank this month and is add-to-cart still firing normally” without opening Event Segmentation.

Reconciling against Amplitude

Where to look in Amplitude’s own dashboard: Use Event Segmentation in Amplitude with the “totals” measure and group by event type, then sort by count to see the same ranking. The Data section’s event list and volume views also show per-event throughput and are useful for confirming an event’s count and whether it is still active. Match the date range, interval, and any event or segment filters to the Vortex IQ profile before comparing positions. Why the Vortex IQ value may legitimately differ: Cross-connector reconciliation: complement with sibling cards in the same category for the full diagnostic picture.

Known limitations / merchant FAQs

Q: How often does Top 10 Events by Volume update? The card refreshes on the standard data refresh (typically every 30-60 minutes for live integrations). For real-time signals, force a manual refresh from the dashboard. Q: Why does my Amplitude dashboard show a different number? Rankings and counts shift with the date range, time zone, and which events are in scope. Differences usually come from period boundaries (30-day rolling vs calendar months), time-zone alignment, or filters that exclude certain events. Match these settings before assuming a real divergence. Q: How does Top 10 Events by Volume relate to other engagement metrics? This card decomposes Total Event Volume into its largest contributors. Read it alongside Core Events Firing to confirm commerce events are healthy and alongside Event Taxonomy Drift to catch new or rogue events climbing the list. Q: Can I customise the alert threshold? This card ships without a default alert trigger because it is a ranking rather than a single value. Related cards such as the Event Volume Drop alert and Event Taxonomy Drift carry configurable thresholds in the Alert Rules tab to watch for the failure modes this list reveals.
