The problem

Tests take too long.
And cost too much.

Idea → Briefing → Design → Dev → QA → Launch: Weeks pass before a single A/B test goes live. Every test ties up developer capacity - and without AI support, this quickly becomes expensive.

Ø 2-4 weeks per test

Weeks pass between the initial briefing and the go-live. Hypotheses gather dust in the backlog because manual implementation is too time-consuming - this is exactly where AI-supported A/B testing comes in.

Expensive due to dev dependency

Every test requires developer resources - be it for front-end changes, QA or deployment. This costs time and money that is lacking elsewhere.


Prompt Based Experimenting

Describe your hypothesis.
The AI builds the test.

Formulate your idea in natural language - the AI creates a testable variant that you can iteratively adapt using a prompt. If required, you have direct access to the generated JavaScript to save developers time.

1

Formulate promptly

Describe your idea in natural language - no technical details necessary, the AI understands your optimization idea immediately.

2

AI creates the variant

Varify generates a variant including code. You can refine it iteratively using the prompt - or switch directly to JS.

3

Experiment starts immediately

Check, release, live - your AI-generated experiment runs in under 2 minutes. GA4 tracking is configured automatically.

AI CRO Audit

Your site, AI-analyzed.
Priorities delivered immediately.

Varify automatically scans your most important pages for conversion barriers - and delivers a prioritized list of optimization points, directly as testable hypotheses for Prompt Based Experimenting.

Immediate hypotheses

Each finding is a testable hypothesis - one click starts the experiment directly via Prompt Based Experimenting.

10,000+ test patterns

Recommendations are based on CRO patterns from real experiments - not generic tips.

Prioritized by impact

Severity + estimated CVR uplift - you know immediately which test you should start first.

Example: Audit report for my-shop.com/product/premium-sneaker
Critical

CTA below the fold on 68% mobile devices

The „Add to cart" button is not visible on the most commonly used viewports (375×667, 390×844) without scrolling. Test sticky CTA or position shift. Potential: +12-18% Mobile CVR.

Critical

No trust signal in the buy box area

Neither the seal of approval nor the number of ratings are placed in the visible purchase area. Test Trusted Shops badge + star snippet directly next to the price.

Medium

No urgency element despite limited product

Product name contains „Limited Edition", but availability and remaining quantity are not communicated. Test stock display or countdown.

Medium

CTA button contrast under WCAG AA on mobile

Blue button (#2563eb) on light background - contrast ratio 3.8:1 instead of min. 4.5:1. Test darker tone or larger font.

Optimization

Product images without zoom on desktop

High-resolution images available, but no hover zoom or lightbox activated. For fashion products, zoom increases the dwell time by Ø 15%.

Why Varify AI

Classic CRO process vs.
Varify AI & Prompt Based Experimenting

Criterion Varify AI Classic / other tools
Time to Experiment < 2 minutes per prompt Ø 2-4 weeks (briefing → dev → QA)
Variant generation Automatically via AI prompt Manual: Design + Code + Review
CRO Audit / Prioritization AI-automated + prioritized Manual or agency (from €5,000)
Dev-Dependency None - AI prompts instead of dev sprints Usually 1-2 dev sprints per test
Analytics integration GA4 + BigQuery native Often own tracking system
Costs for scaling Flat per domain, predictable MTU-based - expensive for growth
