Migration guide
Migrate from Google Analytics to Plausible
GA4-to-Plausible is the privacy-focused analytics migration. The biggest win is dropping the cookie consent banner in EU jurisdictions; the technical work is replacing event tracking with Plausible's lighter API.
Time: 1-2 weeks including parallel period.
Migration cost: 5-20 founder hours.
Annualized cost change: GA4 is free; Plausible costs $9-$19/month. You pay slightly more in cash, save substantially in cookie-banner UX cost and developer time.

Why founders make this migration
- Plausible is GDPR-compliant by default — no cookie banner required in the EU.
- Plausible's UI is dramatically simpler; indie SaaS founders actually open it weekly, which GA4's complexity prevents.
- Plausible is open-source with a self-host option if data residency matters.
When NOT to migrate
- If you rely on GA4-specific audience export to Google Ads, Plausible does not replace that integration.
- If you need deep cohort analysis, GA4's free tier still wins — Plausible is intentionally simpler.
The 5-step migration
Step 1
Add Plausible script alongside GA4
Plausible's script is one line. Add it to your site head; do not remove GA4 yet. Both run in parallel.
Pitfall: Removing GA4 before Plausible has 30 days of data. The historical comparison is the migration's quality check.
Step 2
Recreate custom events
List every GA4 custom event you depend on. Plausible's custom event API is simpler but uses different syntax. Map each event.
Pitfall: Skipping events because they 'do not matter' — usually two months later you discover one of them was load-bearing.
Step 3
Update funnel reports
Plausible's Goals + Funnel features replace GA4's funnel exploration. Recreate the key funnels you check weekly.
Pitfall: Trying to recreate every GA4 exploration. Most are unused; rebuild only the ones you actually open.
Step 4
Run parallel for 30-60 days
Compare Plausible vs GA4 numbers daily. They will differ slightly (Plausible's no-cookie design produces lower unique counts on bouncy traffic); calibrate your expectations.
Pitfall: Panicking at the difference and reverting. The numbers being different is the whole point.
Step 5
Remove the GA4 script and cookie banner
Once Plausible is the trusted source, remove GA4 and the cookie consent banner (if GA4 was the only consent-requiring tracker).
Pitfall: Forgetting to remove the cookie banner. It is the most visible signal of the migration to your visitors.

Frequently asked
- What about historical GA4 data?
- Export GA4 data to BigQuery before removing GA4. Plausible does not import historical data — treat the migration date as a clean break for analytics, and reference GA4 exports for pre-migration analysis.
