Metrics, goals, and conversion tracking

Simple terms

Metrics tell Apex what success means for a test: a click, pageview, custom event, revenue event, or Shopify event.

Creates reusable success events for experiments: click, pageview, custom, revenue, and Shopify-connected conversion goals.

Routes

• /goals
• /goals/new
• /goals/new/visual

Implementation behavior

• A Goal stores type, selector, URL pattern, event name, capture rules, text matching, revenue settings, and count-once behavior.
• Click goals bind to selectors in the SDK; optional capture rules can store element text, value, attribute, or dataset values.
• Pageview goals match URL patterns after the SDK sees a page event.
• Custom and revenue goals are tracked through SDK calls or Shopify event integrations.
• Experiments attach goals through ExperimentGoal, with one goal marked primary for readback and launch criteria.

How to use it

• Create reusable metrics before building an experiment.
• Use click goals for UI actions, pageview goals for route arrival, custom goals for product events, and revenue goals for order value.
• Verify selectors in QA before launch.
• Mark one primary metric per experiment and keep secondary metrics for diagnostics.

When not to use it

• Do not use a click goal when the real outcome is revenue or checkout completion.
• Do not use fragile selectors that depend on generated class names if a stable selector exists.
• Do not mark multiple goals as primary for the same experiment decision.

Implementation source

• Metric pages live under src/app/(dashboard)/goals.
• Handlers live under /api/goals, /api/generate-selector, and goal-verification experiment QA routes.
• The SDK binds goal listeners and sends matching events through the Worker into Tinybird.

Data and API

• Prisma models: Goal, ExperimentGoal, ShopifyEventSetting.
• APIs: /api/goals, /api/goals/[id], /api/generate-selector, /api/experiments/[id]/qa/goal-verification.
• Events land in Tinybird events with event_type, experiment_id, variation_id, properties, and timestamp.

Failure modes

• Selector does not fire: inspect DOM timing, selector specificity, and whether the element is replaced after SDK binding.
• Revenue missing: confirm Shopify/web pixel settings or custom revenue payload shape.
• Conversion rate looks wrong: check count-once rules, bot/internal traffic, and whether the primary goal is attached to the right experiment.
