Measurement before the test.

GA4 and Tag Manager are how we know a change moved a lead or an order.

How to use this

Pick the stack you are staying on.

Installing a testing tool on a broken event model produces confident nonsense. These two pages are the measurement layer. Experiment platforms in the VWO or Optimizely category are used when traffic justifies a license, and they do not have their own page yet.

Platform
GA4
Key events worth testing against, a readable exploration, and no credit given to the install.
Platform
Google Tag Manager
One container, a preview on every publish, and event names a test can read. The container is not the conversion lift.
