How chatting with AI can improve lead quality and conversion rates
Marketers are always battling with budgets. Advertising is expensive, and learning from your missteps is a necessary step.
Experimentation has always been a strong way for marketers to collect real-world data from their audiences that makes it easier for them to learn from their campaigns.
Today, it gives marketers a faster way to collect audience-specific data by turning AI prompts into real, testable changes on live websites in a process called vibe experimentation.
In this guide, we’ll discuss how marketers can use vibe experimentation tools like Prompt-Based Experimentation (PBX) to improve conversion rates, ROAS, and user experience.
What vibe experimentation means for marketers
Vibe experimentation means a tester uses natural language to ideate, create, configure, and analyze experiments on their live site.
PBX builds variants inside your existing design system using your existing targeting setups (versus vibe coding, where the creation takes place offsite), so you can launch your test within minutes and iterate from there.
“One startup I work with went from 24 to 196 experiments in a quarter, smashing their OKRs, just by implementing a vibe experimentation program.”
—Aakash Gupta, Product Growth
AI assists with ideating and launching experiments, but the human tester remains fully in control over which ideas are prioritized, when they are tested, and how long the process lasts, from hypothesis to approval.
Prompt-Based Experimentation (PBX) leads to up to 89% time saved versus manual implementation, according to a Henkan & Partners study that reconstructed historical tests using AI prompts.

Turn more paid clicks into qualified leads
Paid traffic is expensive. Using PBX, marketers can tune landing page experiences based on intent in minutes and then test it on real traffic.
- Fix messaging fast. Align headlines, offers, and CTAs with each ad group. Use a prompt like “Rewrite the hero to match [utm_term], keeping the existing layout.”
- Target the right visitors. Use audience signals you already have to funnel traffic. Use a prompt like “Build a popup to show new users a free trial offer, and a separate one that shows returning users a pricing comparison.”
These prompts would allow you to:
- React quickly to a poorly-performing landing page
- A/B test a campaign in its early stages before committing a full ad budget
Then you can take those paid-for insights and transform them into production-ready tests in the exact same timeframe.
A simple loop to improve ROAS:
- Pick a campaign with rising CPA or poor conversion.
- Audit the first screen: does the page match the ad’s promise?
- Based on your audit, write one precise prompt that fixes message match or reduces friction on the page.
- Run QA with dev, launch the experiment, and monitor primary and guardrail metrics.
- Use built-in sequential testing to monitor your test and start collecting insights.
- Roll out winners and tag them to the campaign to attribute ROAS
- Archive the prompt, variant, targeting, and result, so you can reuse it in future ad sets.
Three prompt-based experiments to try today
Faster reactions to copy, promotions, and layouts means a faster reaction time when those reactions are positive or negative. PBX and other vibe experimentation tools are compressing the time between idea and execution and reducing marketer reliance on development teams.
Here are three simple prompts you can use in any vibe experimentation tool to improve your conversion rates and boost lead quality.
1. “Rewrite the hero section copy to align with [campaign keyword]. Keep the same layout. Test three headline options and two CTAs. This test should target new paid visitors. Measure landing page conversion and CPL.”
2. “Redesign the product page to allow users to check out without leaving the page by adding a ‘buy now’ form on the right sidebar. Measure completion rate and ROAS.”
3. “Create a popup to offer returning customers with average spends of $80-$90 a discount code for free shipping if they spend $100 or more. Measure add-to-cart rate and revenue per session.”
