15 GPT-5.5 Prompts to generate A/B Tests Ideas
I built 15 prompts that turn GPT-5.5 into a senior CRO strategist. Most A/B test ideas fail because they start with opinions, not evidence. "Let's try a green button."
Free. Five quick questions, then it's yours.
What's inside
What you get
"What if we made the headline bigger?"
"I read on Twitter that urgency works."
That's not CRO. That's guessing with extra steps.
Not "write me a headline" prompts.
Hypothesis-grade prompts. Backed by psychology, friction analysis, and prioritization logic.
You get 15 prompts inside the playbook:
Diagnose: funnel drop-offs, session replays, cart abandonment
Hypothesize: psychology-backed, JTBD, objection stack
Sharpen: headlines, CTAs, above-fold rebuilds
Validate: heatmaps + voice-of-customer
Prioritize: ICE ranking, devil's advocate, post-test compounder
This is the exact stack we use at DRIP across 4,000+ A/B tests and €500M+ in tracked revenue for brands like HelloFresh and SNOCKS.
Two rules we don't break:
1\. AI generates hypotheses. Never decisions.
2\. No test runs without a learning hypothesis. If you can't articulate what a loss teaches you, the test isn't worth running.
