What is a Google Analytics 4 migration proposal?

A GA4 migration proposal outlines your plan to transition a company from Universal Analytics (UA) to Google Analytics 4. It typically includes setup, property configuration, event mapping, tag updates, testing, and reporting alignment.

This type of proposal is commonly used:

  • When UA is deprecated and GA4 is now the standard for web analytics
  • To preserve continuity in traffic, conversion, and behavior tracking
  • When companies want to avoid data gaps or misconfigured GA4 setups
  • As part of a broader analytics or MarTech stack audit

It helps clients future-proof their tracking, ensure clean data, and build reports that actually match business goals.

A strong proposal helps you:

  • Translate legacy tracking setups into GA4’s event-based model
  • Set up clean, usable GA4 dashboards for real teams — not just raw data
  • Integrate GA4 with Google Tag Manager, Ads, BigQuery, or Looker Studio
  • Avoid common pitfalls like duplicated events, broken goals, or missing ecommerce data

When to use this proposal

Use this GA4 migration proposal when:

  • A client is still using Universal Analytics or hasn’t completed their GA4 setup
  • They have GA4 installed but reporting is inaccurate or incomplete
  • They need help mapping legacy events, goals, and conversions into GA4’s data model
  • GA4 data doesn’t match Ads, CRM, or ecommerce results — and they want answers
  • You’re helping with broader analytics or CRO setup and need to fix the foundation

It’s especially useful when they’ve installed GA4 — but haven’t properly configured or validated it.

What to include in a Google Analytics 4 migration proposal

Use this template to walk the client through a clean, phased GA4 migration — from audit to handoff — in clear, structured language.

  • Project overview: Frame the problem — sunsetted UA, broken tracking, untrustworthy reports — and how your migration fixes it.
  • Discovery and audit: Review existing UA and GA4 setups, GTM containers, hardcoded tags, event naming, and key business KPIs.
  • Property configuration: Set up or clean GA4 property settings, including data streams, retention, internal traffic filters, and attribution model.
  • Event and goal mapping: Translate UA events/goals into GA4’s event structure. Define key conversions and engagement metrics by business need.
  • Tag updates: Rebuild or replace tags in Google Tag Manager. Ensure proper event triggers, ecommerce tagging, and parameter passing.
  • Testing and QA: Validate that data is flowing correctly. Compare GA4 vs UA where needed, flag discrepancies, and adjust as required.
  • Reporting setup: Build dashboards in GA4 or Looker Studio to match business needs — e.g., acquisition, funnel drop-off, product engagement.
  • Training and handoff: Provide documentation, walkthroughs, or a live session so the team understands how to use the new reports.
  • Timeline and phases: Break into audit, setup, QA, reporting, and training — with duration estimates for each.
  • Pricing: Offer fixed-fee or milestone-based pricing. Include optional add-ons like monthly reporting or BigQuery export setup.
  • Next steps: End with a CTA — such as granting access, sharing KPIs, or scheduling a kickoff session.

How to write an effective GA4 migration proposal

This proposal should feel clean, technical, and business-aligned — especially for teams frustrated by messy or missing data.

  • Focus on trust and continuity: Most clients aren’t analytics experts — they just want numbers they can believe.
  • Don’t overcomplicate: Use plain-English explanations of what GA4 will track and how it supports key decisions.
  • Anchor in business metrics: Connect every step to revenue, retention, or engagement — not just “pageviews” or “bounce rate.”
  • Flag what’s missing in GA4: Warn clients about features lost in the transition (e.g., simple goals, views) — and how to replicate or replace them.
  • Build for reuse: Make sure reports can be accessed and updated by non-technical users after you hand off.

Frequently asked questions (FAQs)

How long does a GA4 migration take?

Usually 2–4 weeks depending on complexity — including discovery, tag setup, QA, and reporting configuration.

Do I need access to Google Tag Manager?

Yes — especially for tracking updates. If the site uses hardcoded tags or another TMS, flag this during the audit.

Should I migrate historical data from UA to GA4?

You can’t migrate data directly — GA4 is a different model. Recommend exporting UA data separately for archival or comparison use.

Can I recreate UA goals in GA4 exactly?

Not always. GA4 uses an event-based model. Some goals will need to be rebuilt using custom events and parameters.

Should I build reports in GA4 or Looker Studio?

Depends on the client. GA4’s built-in reports are limited. Looker Studio is better for team dashboards and executive summaries.
