A/B Testing
See which version wins before you build it.
Put two variants in front of the same audience and compare them across all 12 psychology scores. Evelance names the winner and shows you the score that decided it. No live traffic required.
Two variants, one audience, every score
Run version A and version B against the same personas at the same time. Each one is read across the full set of 12 scores, so you see where a change helped and where it quietly cost you.
Comparison scorecard
A win on one score can hide a loss on another
Here two pricing-page layouts go head to head with the same audience. Variant B pushes people closer to action and gives up credibility to get there. The scorecard shows both at once.
- Interest Activation 7.2 8.4Winner
- Credibility Assessment 8.3Winner 6.9
- Value Perception 7.1 7.9Winner
- Emotional Connection 6.8 7.6Winner
- Confidence Building 7.9Winner 7.2
- Action Readiness 7.0 8.6Winner
Variant B takes the win on Action Readiness and Value Perception. It loses Credibility Assessment by 1.4 points. The recommendation is to ship B's layout and add back the trust cues Variant A handled well.
Persona scores agree with real-user feedback 89.78% of the time, so a comparison points the same direction a live test would, days sooner.
What the comparison gives you
No live traffic
You do not need visitors, a running experiment, or weeks of data. Both variants are scored before either one ships.
A winner and the reason
Every run names the stronger variant and the score that decided it, written in plain language a stakeholder can read.
Retest after every change
Fix the losing variant and run it again in minutes. Watch the credibility gap close without touching the score that was already ahead.

Put any two treatments head to head
If you can upload it, you can split it. The same audience reviews both sides, so the score gap reflects the change you made and nothing else.
-
Buttons and CTAs
Two labels, two colors, or two placements scored for how hard each one pushes toward the click.
-
Page layouts
A current page against a redesign, read across the full 12 before the rebuild starts.
-
Headlines and messaging
Two value propositions compared on how clearly each one reaches the audience you name.
-
Pricing and offers
Two pricing tables or offer framings measured for value perception and action readiness.
Frequently asked questions
How does A/B testing work in Evelance?
You upload both variants, describe the audience you want feedback from, and run them together as an A/B Comparison. The same personas review each version and score it across all 12 psychology dimensions. Evelance returns the two score sets side by side, names the stronger variant, and explains the reasoning in a written summary. A full run takes 10 to 30 minutes.
What can I compare?
Anything you can upload as a URL, an app screen, a prototype, or a design file. Common comparisons include two checkout buttons, two pricing layouts, a pair of homepage headlines, or a full redesign against the current live page. Because both variants face the same audience, the difference in scores reflects the change you made rather than a shift in who happened to see it.
Do I need live traffic or a running experiment?
No. A traditional split test needs visitors, an even audience split, and enough conversions to reach significance, which can take weeks. Evelance scores both variants against modeled personas before either one ships, so you get a directional read on a prototype or an unreleased page without an audience of your own. When traffic is scarce, this is often the only way to compare two options at all.
How is the winning variant decided?
Evelance compares the two variants on every one of the 12 scores and weighs the gaps. The variant that leads on the scores tied most closely to your goal, such as Action Readiness for a checkout flow, is named the winner. The summary states the deciding metric and the size of the margin, so you can judge how firm the call is before you act on it.
Can I compare more than two variants at once?
An A/B Comparison handles two variants in a single run. To weigh three or more, run the winner of one comparison against the next contender, or switch to Competitive Benchmarking, which scores several designs together in one pass. Each additional run uses the same small batch of personas and finishes in minutes, so a bracket of four options resolves in an afternoon.
What happens when a variant wins some scores and loses others?
That is the common case, and it is where the scorecard earns its place. A bolder pricing layout might raise Action Readiness while dropping Credibility Assessment. Evelance shows the trade on every score instead of a single yes or no, so you can ship the winning structure and repair the one weakness that held it back rather than guessing what moved the number.
How fast are results?
Most comparisons return in 10 to 30 minutes. A run uses 8 to 12 personas per variant, and they review both versions in parallel. You can adjust the weaker variant and rerun the comparison the same afternoon, which turns iteration into a loop measured in minutes rather than a wait measured in days.
What does an A/B comparison cost?
Pay as you go, with no subscription. Each persona costs $2.99, and volume packs lower the unit price. A typical comparison runs 8 to 12 personas per variant and costs roughly $23.90 to $29.90, well below a traffic-based test that ties up a page and weeks of visitors before it reads a result.
