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

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.
