Why CRO-W

Stop waiting on developers to test ideas

Run experiments yourself. When something wins, hand proven changes to engineering — not hypotheses.

Edit Without Engineering

Click any element — text, images, colours, layout. Build variants visually. No Jira ticket, no sprint planning, no waiting.

Test Entire Funnels

Go beyond single-page tweaks. Track visitors across every step — landing page, form start, submission, conversion — and see where they drop off.

Ship Wins to Engineering

When a variant wins, export the exact changes — selectors, edits, styles. Engineering gets a proven spec, not a guess. Quick rollout, no rework.

Statistical Proof, Not Opinions

Real-time p-values tell you when a winner is statistically significant. Walk into the engineering standup with data, not a hunch.

Live in 2 Minutes

One script tag or GTM snippet. Works with any site — WordPress, Webflow, custom builds. No CSP config, no backend changes.

AI-Powered Suggestions

Not sure what to test? Get AI recommendations for copy, layout, and CTA changes based on your page and industry.

How It Works

Launch a test in three steps

From idea to live experiment in under two minutes. Seriously.

01

Make your changes

Click elements to edit text, swap images, tweak colours, or rewrite HTML. See changes live as you build.

03

Add the tracking snippet, hit "Set Live", and watch real-time analytics roll in. CRO-W tells you when you have a winner.

FAQ

Common questions

How does CRO-W work with my existing website?

You add a single JavaScript snippet to your page (or via Google Tag Manager). CRO-W intercepts the page load and applies your variant changes on the fly — your original site stays untouched.

Do I need a developer to set it up?

No. If you can paste a snippet into GTM or your page header, you're good to go. The visual editor handles everything else — click elements, edit text, change colours, all without code.

How is traffic split between control and variant?

CRO-W uses cookie-based bucketing to give each visitor a consistent experience. Traffic is split 50/50 automatically. The same visitor always sees the same version.

When do I know if my test has a winner?

CRO-W calculates significance in real-time. Free plans use chi-square testing; paid plans unlock Bayesian analysis that lets you call winners up to 40% sooner — no fixed sample sizes needed. We flag the winner at 95%+ confidence.

Can I test across multiple pages in a funnel?

Yes. CRO-W supports multi-step funnel tracking. Capture each step, track visitors through your entire flow, and see exactly where drop-offs happen for both control and variant.

What happens if I go over my plan limits?

We give you a 20% grace buffer so you never lose data mid-experiment. Once you hit 120% of your visitor cap, tracking pauses until the next billing cycle. You can upgrade at any time to unlock more capacity instantly.
