SmartStats For Smarter Business Decisions

We understand that the complexity of data points you need to make the right business call from your experimentation projects can be hard to understand and explain to the relevant stakeholders. In the current business scenario, it is important not only to be right but to do so in the fastest time.

SmartStats, VWO’s Bayesian-powered statistics engine is designed to do the heavy lifting when it comes to calculations and accuracy for you and gives you all the ingredients you need to make the right business decisions.

Configured to deliver data-driven results

SmartStats is engineered to compute accurate results for all your goals. It is configured to help you make the right business decisions without worrying too much about the statistics. We got you covered there while you focus on more important business goals.

It gives easy to digest metrics along with recommendations so that you can stop looking up the definition of p-value or verify statistical significance but only focus on what your next steps should be.

You don’t have to worry about making the wrong decisions based on less data. Your results are valid whenever you look at them.

SmartStats speed gives you a headstart over your competitors

Speed is the new competitive advantage. Websites are dynamic, and a lot keeps happening every day. Understanding what customers want from you is the holy grail of marketing. Given all these, can you really wait for the absolute truth? Or just go with the better choice?

SmartStats engine gives you intelligent results to make smarter business decisions and reduces your testing time by half. Unlike most of our competitors who just test for statistical significance, with SmartStats, we directly address your real question—what is the probability of a variation A beating variation B and by how much.

This cuts down the waiting time in the testing phase. Finding intelligent answers quickly can widen your pipeline. You can run more tests, learn faster, and improve conversions quickly. SmartStats is faster than Frequentist! Don’t take our word for it. Compare it with the calculator for your campaign.
