Google Analytics is installed on roughly half the web. It answers some questions well — where traffic comes from, which pages are most visited, how many sessions you are getting. But it leaves significant gaps, particularly for developers who need to understand application performance rather than just marketing attribution.
What Google Analytics Does Well
GA4 is genuinely useful for traffic source attribution, conversion funnel analysis, audience segmentation, and integration with Google Ads. If your primary question is 'which marketing channel is driving signups?', GA is a reasonable answer. It has a large ecosystem, deep documentation, and many teams already know how to use it.
What Google Analytics Does Not Tell You
GA does not capture Core Web Vitals from real user sessions. It does not show per-page load performance, JavaScript errors, or how performance varies across device types or geographies. It does not tell you whether users are bouncing because of a 4-second LCP or because your content is not relevant. It is a marketing tool, not a performance monitoring tool — and using it as both leaves dangerous blind spots.
The Performance Gap
Performance data and traffic data are almost always siloed. You might know from GA that a page has a high bounce rate without knowing from your monitoring that the bounce is driven by a 3.8-second LCP on mobile. Without connecting these two data sources, you are optimising for the wrong things. You rewrite the copy when you should be optimising the images.
What Good Frontend Analytics Looks Like
- Core Web Vitals (LCP, CLS, INP, FCP, TTFB) captured from real user sessions across all device types
- Geographic performance distribution — are users in certain regions getting significantly worse performance?
- Session duration and unique visitor counts that do not require third-party cookies
- Traffic source attribution that connects marketing channels to actual user behaviour
- Page view trends over time that you control, own, and can query without data sampling
Privacy and Simplicity
Many teams also want frontend analytics that are simpler to configure, GDPR-friendly by design, and do not require a full tag management system. Custom or lightweight analytics solutions can be privacy-respecting, easy to set up, and integrated directly with your backend monitoring — giving you the full picture in one place rather than across multiple disconnected tools.
Statvisor captures page views, sessions, visitor geography, traffic sources, and all five Core Web Vitals from real user sessions — in the same dashboard as your backend API monitoring, with a single SDK and no cookie consent overhead.
