You're here because you want more conversions and fewer guesses. Good instinct. Let's get you set up.

CROLabs (Conversion Rate Optimization Labs) is built for marketers, founders, and agencies who want to improve conversion rates without waiting on developers or wrestling with complicated tools.

The idea is simple. Analyze the page, test a better version against the original with real traffic, learn from the data, keep going. No tool chaos, no endless back-and-forth. Just clear answers about what works for your audience.

What's new is that you don't have to run that loop by hand anymore. You still can, if you want to. But you can also hand it over.


How It Works

CROLabs is a multi-agent AI CRO engine. In practice that means a group of agents does the slow parts of conversion optimization for you, and you stay the one who decides what goes live.

The loop has four steps, and it keeps going.

1. The agents analyze your site. They read your pages, learn your goals, and look at where visitors are dropping off. Out of that comes a list of things worth testing, ranked by likely impact.

2. You approve the variants. The agents write the copy, build the changes, and generate the visuals. You review and approve. Nothing goes live without you.

3. Approved variants go live and get tested. Traffic splits automatically between the original and the variants, and each visitor sees the version most relevant to them.

4. Everyone learns. Every visitor feeds the next round. The agents work out what your audience responds to and use it to generate better ideas next time.

The short version is that the agents do the work and you keep control.

Two Ways to Run It

You make this choice when you create a lab.

Self-managed. You're hands-on. You create experiments, build variants in the no-code Visual Editor, set goals, and run tests yourself. Full control over every step.

AI-managed. The agents do the work. They analyze your page, propose hypotheses, build the variants, and run them one after another. You review and approve what goes live. An hour or two a week.

Either way, nothing is tested without your say-so, and the engine underneath is the same. Same tracking, same goals, same analytics. The only thing that changes is who does the work of creating and running experiments.

See Choosing Your Lab Type for help deciding.
