FAQs

Is there a limit to the number of A/B tests I can run at once?

No. Run as many concurrent experiments as you need with no caps on test volume. CROforce is built to handle multiple simultaneous tests without performance degradation or test interference.

Do I need a developer to set up basic A/B tests?

No. Our visual editor lets you create and launch experiments without writing a single line of code. For more advanced functional changes, you can use the code editor—but basic tests are fully self-serve.

How does the statistical model determine a winner?

CROforce uses Bayesian statistical analysis that calculates the probability of one variation outperforming another based on real visitor behavior. This approach delivers reliable results faster than traditional frequentist methods and avoids misleading, arbitrary significance thresholds.

How long should an A/B test run to get reliable results?

It depends on your traffic volume and the size of the conversion lift you're measuring. Most tests need at least one to two full business cycles to account for natural traffic fluctuations. CROforce provides real-time statistical confidence indicators so you know exactly when results are reliable enough to act on.

Does the platform support server-side or client-side testing?

Both. CROforce supports client-side testing for UI changes, layout modifications, and visual experiments—as well as server-side testing for deeper functional changes, backend logic, and performance-sensitive experiments. Use either approach or combine them depending on what you're testing.

How is sensitive data handled in experiments?

We do not collect or store any personally identifiable information. All experiment data is anonymized and aggregated. CROforce is SOC 2 certified and fully GDPR compliant.

What is the impact of the script on site speed and Core Web Vitals?

Our lightweight script processes tests before the page renders, eliminating flicker and layout shifts to ensure minimal impact. We continuously monitor Core Web Vitals to ensure the platform has no impact on site performance.

How often should I run A/B tests?

All the time—the highest-performing optimization programs run tests continuously to build compounding conversion gains. Every test—even one with no lift—generates insights that improve your next experiment.

How do I decide what to test first?

Start with your highest-traffic, highest-value pages where even small conversion improvements generate meaningful revenue. CROforce also offers optional AI-driven test recommendations that analyze your site data and surface high-impact opportunities ranked by potential uplift.

Does running an A/B test affect my Google Search rankings (SEO)?

No. Our tests run on the same URL with changes applied client-side, so there is no content duplication or URL splitting. Search engines see your original page while visitors see their assigned variation.
