Goal tracking, event setup, and the privacy-first vs data-rich trade-off. GA4 vs Plausible vs Fathom — pick the tool that fits your stack and compliance needs.
Most sites either skip analytics entirely or install Google Analytics on day one without thinking about it. Both are mistakes — the first means you're flying blind, and the second can mean a cookie-consent banner, a GDPR conversation, and a dashboard so dense you never actually open it.
The real decision isn't "which tool is best" — it's "how much depth do I need, and how much privacy compliance can I afford to skip thinking about." GA4 gives you enormous depth and cross-channel attribution for free, in exchange for cookies, a learning curve, and a consent banner in most jurisdictions. Plausible and Fathom trade some of that depth for a lightweight script, no cookies, and dashboards simple enough to actually check daily — at a monthly cost.
There's also a quieter factor that rarely makes it into the comparison posts: how much you trust yourself to actually configure GA4 correctly. It's a genuinely powerful tool, but its event model, consent requirements, and reporting interface have a real learning curve — a half-finished GA4 setup tells you less than a fully-finished Plausible one, even though GA4 is "more powerful" on paper.
Same job — telling you who visits and what they do — three very different philosophies.
| Tool | From | Cookies | Script Size | Best For | Depth |
|---|---|---|---|---|---|
| GA4 | Free | Yes, by default | Heavier | Cross-channel attribution, ad ROI | Highest, steep curve |
| Plausible | $9/mo | None | ~1 KB | Privacy-conscious sites, EU compliance | Focused, lightweight |
| Fathom | ~$15/mo | None | ~1 KB | Simplicity, fast load times | Focused, lightweight |
The comparison table tells you the numbers. This is what it actually feels like to live in each dashboard.
Installing the tracking snippet is step one out of six — most sites stop there and wonder why their data never tells them anything useful.
Plausible and Fathom scale by monthly pageviews. GA4 stays free regardless of traffic.
| Tool | Up To 10K Views/mo | Up To 100K Views/mo | Enterprise |
|---|---|---|---|
| GA4 | Free | Free | GA4 360 — custom pricing |
| Plausible | $9/mo | ~$19/mo | Custom volume pricing |
| Fathom | ~$15/mo | ~$25/mo | Custom volume pricing |
If you run paid ads and need attribution across channels, or just don't want to pay monthly for analytics — GA4. If you're EU-based, privacy-conscious, or just want a dashboard you'll open every day without dreading it — Plausible or Fathom, which are close enough in capability that picking between them mostly comes down to dashboard taste.
Whichever you pick, the setup steps above matter more than the tool — a sloppy GA4 install tells you less than a clean Plausible one.
Read The Full GA4 vs Plausible ComparisonTechnically yes — they don't conflict. Practically, most sites that try this end up checking neither dashboard regularly because the numbers never match exactly (different bot filtering, different session definitions). Pick one as your source of truth.
If you have visitors in the EU, UK, or several other jurisdictions with similar privacy laws, yes — GA4 sets cookies by default, which legally requires consent in those regions. Cookieless tools like Plausible and Fathom sidestep this requirement entirely.
Every event you track is just data. A "key event" (GA4's renamed version of "conversion") is an event you've explicitly flagged as meaningful, which then surfaces in conversion-rate reports and lets you build audiences and bid strategies around it.
You won't be able to merge histories between tools, but you can export and archive your old data before switching, and most teams find a clean break with a known start date is simpler than trying to reconcile two different measurement philosophies anyway.
Server-side tracking sends data from your own server instead of the visitor's browser, sidestepping ad-blockers and browser tracking prevention. It's worth the extra setup for ad-heavy businesses leaking significant attribution data — overkill for a small content site or portfolio.
Apple's Intelligent Tracking Prevention limits cookie lifespan and can undercount returning visitors in cookie-based tools like GA4. It's part of why "session" counts have gotten noisier industry-wide, and another reason cookieless tools like Plausible and Fathom report cleaner numbers for Safari traffic.
You can, and some teams do treat one as a backup. Just decide upfront which one is your source of truth for reporting — running both as equals tends to create more confusion than confidence when the numbers inevitably diverge.
