VWO Review
A/B Testing · Analytics & Conversion
Proper A/B testing and experimentation — for when you have enough traffic to prove things.
Our take
Only useful above a real traffic threshold. Below a few thousand conversions a month you will never reach significance — spend that budget on Clarity and better copy instead.

What VWO does
VWO is a full experimentation platform: A/B and multivariate tests, personalisation, a visual editor for building variants without a developer, and the statistical rigour to tell you whether a result is real.
How marketers actually use it
Form a hypothesis from your Clarity recordings, build the variant in VWO’s visual editor without a developer, and run it until it reaches significance. The discipline of that loop matters more than the tool.
Best for
- A/B testing landing pages and checkout flows
- Building test variants without developer time
- Personalising experiences by segment
- Teams with enough traffic to reach significance
Watch out for
Needs substantial traffic to produce trustworthy results, and it is expensive. Badly run tests are worse than no tests.

Is VWO free?
There is a limited free starter plan. Paid plans are priced by tracked visitors and get expensive quickly.
How much traffic do I need for A/B testing?
More than most sites have. Below a few thousand conversions a month you will rarely reach significance — spend that budget on better copy and Clarity instead.
Is A/B testing worth it for small businesses?
Usually not yet. Badly run tests are worse than no tests, because they produce confident conclusions from noise.
How long should an A/B test run?
Until it reaches statistical significance and covers at least one full business cycle — usually two to four weeks. Stopping early because a variant looks ahead is the most common testing mistake.
What should I do instead if I lack traffic?
Watch Clarity recordings, run exit surveys, and fix the obvious problems. Below a few thousand conversions a month, qualitative research beats testing every time.
