Custom Event & Parameter Tracking
Tracks basic interactions like button clicks using simple JavaScript events.	Utilizes a flexible, parameter-based event model for tracking user interactions.	10
Funnel & Drop-off Analysis
	Allows creation of custom funnel explorations to track user steps and drop-off rates.	10
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 uses a structured schema for complete lifecycle tracking.	10
Identity Resolution
	Utilizes a blended approach prioritizing user-provided IDs, then vendor signals, and device IDs.	10
GDPR / CCPA Compliance
Built on a privacy-first architecture, bypassing GDPR and CCPA cookie consent banners.	Its compliance features include Consent Mode, IP redaction, and data deletion requests, but full compliance relies heavily on proper implementation by the user.	10
Mobile app analytics
	App tracking is handled natively through deep Firebase integration, providing a unified reporting structure for both web and mobile platforms.	10
Audience Segmentation
	Creates specific audience segments that sync with Google Ads automatically.	10
Cookieless Ping / Consent Mode
Utilizes anonymized hashing to track aggregate traffic without needing privacy consent banners.	Utilizes Consent Mode to send anonymized data signals when cookie tracking is denied, aiding in measurement gap filling.	9
Path Exploration / User Flows
	The pathing tool visualizes the sequential flow of users through a site or app, starting from a specific event or working backward from a conversion.	9
Cohort & Retention Analysis
	The cohort tool enables teams to group users by shared characteristics (like acquisition date) to track retention, engagement, and conversion decay over time.	9
Attribution Modeling
	Uses data-driven models to distribute conversion credit across marketing touchpoints.	9
Raw Data Export (BigQuery/S3)
Allows basic, aggregated data export via CSV or API, but lacks raw hit-level data.	Exports complete, unsampled event data via native integration with Google BigQuery at no additional cost.	9
Native SDKs
	Mobile app measurement is supported through dedicated Firebase SDKs for both iOS and Android environments. It features automatic logging for standard app interactions alongside the ability to define custom events.	8
Data Sampling Control
	To maintain platform speed during complex queries on large datasets, the system applies data sampling, estimating results based on a subset of data.	8
Proxy Deployment / Custom Domain
	Through Server-Side Google Tag Manager, businesses can route their tracking data through a first-party server before it reaches the analytics platform.	8
Data Retention Limits
Stores aggregated, anonymized data indefinitely, ensuring unlimited historical access.	Administrators can configure how long user-level and event-level data is stored before it is automatically deleted from the platform's servers.	8
Custom Dashboard Builder
	Native dashboard capabilities are limited to customizing standard reports and creating Explorations. For comprehensive, executive-level dashboards, users must rely on the native integration with Looker Studio.	7
Real-time Reporting
The main dashboard features a live visitor counter that displays the number of users actively browsing the site at any given moment.	Live data monitoring provides a snapshot of current active users, their geographic locations, and the events they are triggering within the last 30 minutes.	7
Bot Filtering
Automatically blocks common bot, crawler, and spam traffic at the server level to maintain 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.	6
Anomaly Detection
	Utilizes machine learning to establish baselines and flag deviations in core metrics.	6
Predictive Analytics (Churn/LTV)
	Machine learning models predict future user actions like purchase probability or churn risk.	6
SSO Support
	Single Sign-On (SSO) is supported via Google Workspace or Cloud Identity, allowing enterprise teams to centralize authentication and access control.	6
Pre-built Industry Templates
	The platform offers a basic set of report collections and exploration templates tailored to general use cases, rather than highly specialized industry frameworks.	5
