What's the difference between Cloudflare Zone Analytics and Web Analytics?

Zone Analytics is server-side IP-based measurement that counts all traffic passing through the DNS proxy. Web Analytics is a client-side JavaScript beacon using the Performance API. Web Analytics uses a methodology closer to GA4 but doesn't use cookies.

Is using Zaraz with GA4 reliable?

Zaraz provides ad blocker bypass and first-party data advantages, but has known limitations: enhanced measurement events don't auto-fire, engagement time doesn't work properly, and incorrect IP anonymization settings can destroy demographics data. You need to know these limitations and configure accordingly.

Which number should I trust?

Each tool answers different questions. Cloudflare: 'How much traffic is my infrastructure handling, how much is bots?' GA4: 'What are real users doing on the site?' Use both together and track the gap between them as an indicator of client-side tracking loss.

Cloudflare Analytics vs GA4: Why the 5x Difference?

Q: Why does Cloudflare Analytics show far more visitors than GA4?

Cloudflare Zone Analytics works server-side and counts every HTTP request at the DNS level. This includes bots, AI crawlers, API calls, and visitors who don't execute JavaScript. GA4 only sees real users whose browsers can execute JavaScript and who don't use ad blockers.

Why does Cloudflare Analytics show far more visitors than GA4? Cloudflare Zone Analytics, Web Analytics, and Zaraz integration methodology differences explained.

TL;DR

Cloudflare Zone Analytics measures server-side using IP-based counting and includes all traffic including bots. GA4 measures client-side by executing JavaScript and using cookies. Research data shows Cloudflare reports 4.1x more unique visitors and 5.4x more pageviews than GA4. The gap comes from bot traffic, ad blockers, browser privacy policies, and known Zaraz integration limitations.
