Holdout Group for Impact Tracking
Dalton uses a holdout group to measure overall performance:
- Optimized (80%): Traffic seeing Dalton's experiments
- Control (20%): Traffic seeing original pages (no experiments)
Compare these two groups in GA4 to see the combined effect of all Dalton optimizations.
Adjustable Holdout
The control percentage (default 20%) can be changed in Dalton settings.
Setup in Google Analytics
Follow these steps to set up audiences in GA4 that track Optimized vs. Control traffic.
Step 1: Create New Audience
Navigate to Settings → Audiences → New Audience

Step 2: Configure Custom Audience
- Click Create a custom audience
- Select Events as source
- Choose dalton event

Step 3: Set Audience Conditions
Create two audiences using the type dimension:
- One where
type = 'optimized' - One where
type = 'control'

View Results in GA4
Once audiences are set up, compare Optimized vs. Control performance in any GA4 report.
Add Comparison
- Open any report (e.g., Landing Pages)
- Click Add Comparison at the top

- Create comparison groups based on Audience Name

You'll now see side-by-side performance of Optimized (Dalton experiments) vs. Control (original pages) for metrics like conversion rate, bounce rate, and revenue.
