Common Questions About Our A/B Testing Service.
What platforms do you build A/B tests on?
We work across Optimizely, VWO, Adobe Target, Convert, AB Tasty, and Kameleoon. If you use a different platform - just ask.
How long does it take to build one test?
Most experiments are built and QA-tested within 24 hours of receiving a complete brief.
Do you handle QA or do we need to do that?
We handle full QA - cross-browser, cross-device, and flicker testing - before anything goes live.
Can you work with our existing CRO team?
Yes. We work as your development execution arm - your team handles strategy, we handle the build.
Do you offer white-label delivery?
Yes. We can deliver all work under your brand with no Ceptrix branding anywhere.
What do you need from us to start?
A test spec, hypothesis, or design mockup. We confirm scope and cost before starting.
