From idea to winner in four steps
- SetupName it, write the hypothesis, choose which URLs it runs on and how much traffic to include.
- VariantsCreate A/B/n variants. Each variant is a set of changes (text, style, link, hide, redirect) built in the visual editor, with weights that rebalance automatically.
- GoalPick what counts as a win: a click, a page view or a custom event.
- LaunchReview and start. Visitors are assigned a stable variant on their first visit.
What you get in the results
- Exposures, conversions, conversion rate and uplift per variant.
- Confidence from a Bayesian model, and a clear "winner found" status.
- Sample-ratio mismatch (SRM) warnings, so a broken split does not fool you.
- A sample-size estimate before launch, so you know roughly how long a test needs.
- Funnels split by variant, to see where the winner wins and not just that it does.
- Revenue tracking with one line:
window.datsnip.track('purchase', { revenue: 49.99 }). - Roll out the winner as a live patch in one click.
Honest expectations
A test needs traffic. Small effects on low-traffic pages take a long time to prove, so start with changes you expect to matter, and use the sample-size estimate to decide whether a test is worth running.

Frequently asked questions
Can I run A/B tests without developers?
Yes. Variants are built in a visual editor over your live page. You only need a developer once, to paste the snippet.
How long should a test run?
Until it reaches a trustworthy result. Use the sample-size estimate before you launch; low-traffic pages need larger effects to reach confidence in a reasonable time.
Will variants flicker?
Datsnip applies changes as the page loads, and offers an optional anti-flicker snippet that briefly holds the page while variants apply. See the anti-flicker guide for the trade-offs.
Can I test more than two versions?
Yes. Experiments support A/B/n with any number of variants and adjustable traffic weights.
