Test your hypotheses
Begin A/B testing by connecting your tests to your defined hypothesis and linking it back to all the research done in the process. Hypotheses contain an indication of your expectations from the test. By connecting tests with hypotheses, you can see later whether the actual test results were in line with your expectations.
Analyze your campaign performance
Pay close attention to how your A/B tests are performing with VWO’s advanced reporting capabilities.
SmartStats gives you intelligent results to make smart business decisions and reduces your testing time. It is a Bayesian-powered statistics engine built for marketers who need to make decisions based on business realities, not scientists who work in perfect lab conditions.
Improvement & Probability to be best
See the improvement in conversion rate a variation has brought and what is its probability to be the best performing variation.
Conversion rate range
Instead of reporting the number of conversions as a percentage, SmartStats calculates, with 99% probability, the precise range in which your conversion rate lies.
Track impact across funnel
Track multiple metrics for an A/B test to measure its impact across the entire funnel and make informed business decisions.
If your data science colleagues need more details, they can have it all. Absolute potential loss, probability curve graphs, detailed calculation reports, and more.
Slice and dice your test results to uncover hidden winners. Find out if a specific segment of your visitors converted drastically different than the average case for a specific goal or variation.
You can use VWO's 20 pre-built segments like mobile vs. desktop traffic or new vs. returning visitors, or use custom dimensions to compare the conversion of logged in visitors vs. guests or visitors who saw a promotion vs. those who didn’t.
Connect behavioral insights with tests
VWO’s connected platform offers the unique capability of connecting insights from actual visitor behaviors with test data and results.
VWO automatically records heatmaps and clickmaps for visitors becoming a part of your tests. Along with the conversion data for your control and variation, you can visually see what parts of your landing page were more interesting for visitors who converted on the variation.
Want to see how differences in the control and variation impact the way visitors interact with your landing page? VWO lets you filter actual recordings of visitors who saw the control and compare these with the ones who saw the variation to spot changes in the behavior.(VWO Insights Subscription Required )
Verify what your visitors see
Preview and QA the control and variations of your A/B tests before you make these live for your visitors.
Live previews allow you to simulate the variation by loading the variation as it would load for actual website visitors in their browsers. You can verify variations targeted to unique audience sets, see if your traffic allocation is working as expected.
See live previews of your variations on desktop, mobile, tablet devices, and on different types of web browsers to ensure that all your visitors get the perfect experience on your website.
See a static version of control and variation on different browsers. You can group these screenshots by variations or browsers, based on your preference.
VWO Testing has a lot more to offer
Smart notifications give you a quick overview of your test. You can see if a variation resulted in a smart decision, recommended action for your test, and how long you need to run this test.
Run your tests with visitors coming from desktop, mobile, or any tablet device.
Run your A/B tests across domains and capture all the data in a single test.
VWO lets you schedule your A/B test campaigns to start at a later date or time, matching with your unique preferences.

Integrate with third-party apps
VWO integrates with a host of third-party applications including Google Analytics, Kissmetrics, Demandware, Magento, and others. See the complete list of integrations here.
Use VWO’s visitor segmentation to specify which group of visitors sees the variation. You can choose from VWO’s 20 predefined segments like new versus returning visitors, browser, and query parameters, or build your own custom segments using complex logic conditions.
You can pick a goal from your always-on list to measure in an A/B test. In addition to the direct impact of the A/B test on your Goal performance, this also helps you understand how conversions for a specific Goal are impacted by a series of A/B tests.
Want to optimize a goal specific to this A/B test? Define a new goal while creating an A/B test, and VWO will analyze how your test impacts the performance of this goal.
