CROLabs

How does the AI Advisor work?

The agents analyze your page, build variants, and run them as tests. You review and approve what goes live from the backlog. Nothing tests without your sign-off.s

Will CROLabs slow down my website?

No. The script loads asynchronously, so it never blocks your page from rendering. It also avoids layout shifts, which means your Core Web Vitals scores stay unaffected. Variants are applied before the page is visible to the visitor, so there’s no flicker either.

Is CROLabs GDPR compliant?

Yes. CROLabs does not collect names, email addresses, IP addresses, or any other personally identifiable information. All tracking is anonymous and aggregated. You don’t need to add CROLabs to your cookie consent banner for analytics tracking. That said, always check with your own legal advisor for your specific situation.

How much traffic do I need to run a test?

You need at least 300 unique visitors per variant before drawing any conclusions. A standard A/B test with a 50/50 split means roughly 600 unique visitors total. If your page gets less traffic, tests will take longer. Start testing on your highest-traffic pages first for faster, more reliable results.

What's the difference between A/B testing and multivariate testing?

A/B testing compares two versions of a page. You change one thing and see which version converts better. Multivariate testing changes multiple elements at once and measures every combination. A/B tests are simpler and work with moderate traffic. Multivariate tests are more powerful but need significantly more visitors to produce reliable results.
