Custom Event & Parameter Tracking Users can track basic interactions like button clicks or form submissions by attaching simple JavaScript events to specific elements. The platform offers a highly flexible, parameter-based event model to track any specific user interaction. Instead of traditional category-action-label hierarchies, users define custom event names and append specific key-value parameters.

Funnel & Drop-off Analysis Users can build custom funnel explorations to track sequential user steps and identify drop-off rates across any combination of events.

E-commerce Tracking Basic revenue tracking is supported by assigning fixed monetary values to custom events, but it lacks a dedicated e-commerce schema. E-commerce tracking provides a dedicated, structured schema for tracking the complete e-commerce lifecycle, from item views and cart additions to final purchases and refunds.

Identity Resolution The platform uses a blended approach, prioritizing user-provided IDs, then vendor signals, and finally device IDs to deduplicate users across devices.

GDPR / CCPA Compliance out-of-the-box The platform is built entirely on a privacy-first architecture, allowing businesses to legally bypass GDPR and CCPA cookie consent banners. Its compliance features offers features like Consent Mode, IP redaction, and data deletion requests, but full compliance relies heavily on proper implementation by the user.

Cookieless Ping / Consent Mode This privacy-focused approach is a fundamentally cookieless platform by design, utilizing anonymized hashing to track aggregate traffic without requiring privacy consent banners. This platform utilizes Consent Mode to send anonymized, non-identifiable data signals when users deny cookie tracking. These signals feed into machine learning models to fill measurement gaps rather than tracking individual user journeys.

Bot Filtering The platform automatically blocks common bot, crawler, and spam traffic at the server level, ensuring baseline metric accuracy. Automated filtering actively excludes traffic originating from known web spiders and bots based on internally maintained lists. This feature operates entirely in the background and cannot be customized or disabled by the user.
