Welcome! 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 ecommerce teams who want to improve conversion rates without waiting on developers or wrestling with complicated tools.
The idea is simple: form a hypothesis, build a variant, test it with real traffic, learn from the data, and move on. No tool chaos. No endless back-and-forth. Just clear answers about what works for your audience.
What is CROLabs?
CROLabs is a multi-agent AI CRO engine that audits your pages, spots conversion blockers, and turns proven performance marketing principles into prioritized, actionable test recommendations.
You then execute everything in one place. Use the no-code visual editor to change any element on your page, launch A/B tests in minutes, and track conversion goals to confidently pick winners. No developers needed. No separate tools to juggle.
At a high level, CROLabs does three things:
- Tells you what to test: The AI Advisor reviews your pages and recommends the highest-impact experiments based on CRO best practices.
- Lets you build and run tests: The visual editor and experimentation engine handle everything from simple A/B tests to complex multivariate setups.
- Shows you what's working: Analytics and experimentation paths give you a clear picture of what's driving conversions and where users are dropping off.
Core Features
Experimentation
A/B Testing Compare two versions of a page or element to see which one drives more conversions. The classic. Still the most reliable way to validate a hypothesis with real data.
Multivariate Testing (MVT) Test multiple changes at once to find the best-performing combination. Useful when you want to understand how different elements interact with each other, not just which headline wins.
CROLabs Advisor Our multi-agent AI reviews your page, flags conversion blockers, and delivers a prioritized list of recommendations ranked by estimated impact. Run a base analysis or go deeper with Brand Profile and Campaign Data modules for more targeted results.
Analytics
Performance Tracking Track conversion rate, hits, conversions, and time on page over time. See distributions and compare your original against any variant side by side.
Experimentation Paths See the exact journeys users take through your site, where they drop off, and which pages and paths convert best. When you can see where people leave, you know exactly where to focus.
Heatmaps See exactly where visitors click, how far they scroll, and where they get frustrated. Compare click maps, scroll depth, rage clicks, and dead clicks side by side for your original and variant.
Personalization and Targeting
Dynamic Personalization Automatically tailor page content based on visitor signals like behavior, location, device, or traffic source. Show the right message to the right person without building ten separate pages.
Audience Targeting Run tests or personalizations only for specific segments. New vs returning visitors, paid vs organic traffic, specific geographies, devices, or campaigns. You define the audience, CROLabs handles the rest.
