Results & Traffic FAQ

How does the algorithm work?

Dalton uses multi-armed bandits. Traffic starts equal, then shifts toward winners automatically. Poor performers get less traffic quickly.

How long until I see results?

Typically 2-4 weeks. Higher traffic = faster results. The dashboard shows time estimates.

Why don't I see results yet?

Dalton needs data before it can report meaningful results:

• ~250 sessions and ~100 conversion events to start showing reliable data
• Until then, traffic splits equally and numbers will fluctuate

How fast you hit these thresholds depends on your traffic volume. Early numbers are noise—a variant might show +50% one day and -10% the next. Wait for significance indicators before drawing conclusions.

See Understanding the Learning Phase for details.

How do I know when results are significant?

Look for 95%+ certainty in the dashboard. Dalton labels "High Performers" when variants hit significance.

What's the baseline?

By default, Dalton keeps 20% of traffic on your original page to measure against. The remaining 80% goes to experiment variants. You can adjust this split in your settings.

How much traffic do I need?

Minimum 5K monthly sessions per page. Below that, expect 6-8 weeks for results instead of 2-4.

What if an experiment performs poorly?

The algorithm automatically reduces traffic to underperformers. You can also stop any experiment instantly—changes revert immediately.

Can I test multiple languages/countries?

Yes, but each needs separate setup. Start with your highest-traffic market.

Why don't my numbers match GA4 exactly?

Different attribution windows and sampling can cause small differences. The relative comparison (variant vs baseline) remains accurate.
