Send Mida A/B test exposure and conversion events to GA4 for advanced analysis alongside the rest of your traffic data.
Google Analytics 4 (GA4) is Google's flagship event-based web and app analytics platform, used by millions of sites to measure traffic, conversions, and user journeys. GA4 is built around custom events and audiences, which makes it a natural home for A/B test reporting alongside the rest of your acquisition and behavior data.
Mida automatically detects either the gtag function or the dataLayer array on your page and forwards three Mida events — mida_pageview, mida_execute, and mida_conversion — every time a visitor is exposed to a variant or hits a goal. Each event carries the test ID, test name, variant, and Mida user ID so you can build GA4 explorations and audiences segmented by experiment.
Use the test name and variant as dimensions in a free-form GA4 exploration to compare key metrics — engaged sessions, scroll depth, conversions, revenue — across variants without leaving GA4.
Create a GA4 audience like 'Saw variant B of homepage hero' from the mida_execute event. Re-target that audience with Google Ads or sync it to Search Ads 360 for downstream optimization.
Mark mida_conversion as a key event in GA4 and compare counts to your existing GA4 conversion. This is the fastest way to confirm Mida and GA4 agree on attribution before you trust a winner.
Enable debug mode and watch mida_pageview / mida_conversion stream into GA4 DebugView in real time so you can confirm variant assignment and goal firing on your own browser before launching.
Mida and Google Analytics 4 exchange the following events:
| Event | Direction | Description |
|---|---|---|
mida_pageview |
Data out | Fired on every page after the visitor is bucketed into a variant. |
mida_execute |
Data out | Fired only when a test campaign actually executes on the current page. |
mida_conversion |
Data out | Fired when the visitor reaches a Mida conversion goal. |
No. Mida only sends the test ID, test name, variant ID, an anonymous Mida user ID, and a timestamp. No emails, names, or IPs leave Mida.
Either works. Mida detects whichever is present on the page — if both are installed it prefers the dataLayer push so GTM-based reporting setups continue to work.
Mida sends one event per visitor per page, plus one per conversion. For typical sites this is a tiny fraction of GA4's free-tier quota and does not trigger sampling.
Universal Analytics has been sunset by Google. Mida only supports GA4.
Mida is the lightweight A/B testing and personalization platform that integrates with the tools you already pay for.
Mida.so is a super lightweight A/B testing tool to help you experiment, analyze and implement conversion strategies in minutes.
