Google Analytics

Google Analytics is the most widely used web analytics service in the world. It measures how people find and use a website or app - traffic sources, pages viewed, engagement, conversions and revenue - and connects that data to Google's advertising products. The current version, Google Analytics 4, replaced Universal Analytics, which stopped processing data in 2023. GA4 is built on an event-based model rather than sessions and page views: every interaction, from a page view to a scroll, a video play or a purchase, is an event with parameters. That makes it more flexible for tracking apps and modern websites, but the change was disruptive, and many users found the new interface and reports harder to navigate than the old ones. Its main strengths are price and integration. The standard version is free for most sites, and it links directly with Google Ads, Search Console, Merchant Center and BigQuery, so marketers can attribute conversions to campaigns, build remarketing audiences and export raw event data for analysis. Explorations offer funnels, path analysis and cohort reports, and machine-learning features predict likely purchasers and churners. Analytics 360 is a paid enterprise tier with higher limits and service guarantees. The trade-offs are complexity and privacy. Getting reliable data often requires careful configuration through Google Tag Manager, custom events and consent settings, and data thresholds and sampling can hide detail. Under European privacy rules, using GA requires consent management, and some regulators have questioned data transfers, which pushes privacy-conscious sites toward alternatives. Alternatives include Plausible, Fathom and Umami for simple, cookie-free privacy analytics; Matomo for a self-hostable platform close to GA in scope; Mixpanel, Amplitude and PostHog for product analytics inside applications; Microsoft Clarity for free heatmaps and recordings; and Adobe Analytics for large enterprises. Choose Google Analytics when you need free, comprehensive analytics tied to Google's advertising ecosystem. Choose a simpler privacy-first tool when you only need traffic stats without the setup and consent overhead.
