Select your test audience, your way

Extensive audience selection options with your user data to run tests the way you want. Versatile audience selection options VWO has comprehensive options to create and reuse visitor target segments. Create segments based on traffic source, device type, visitor type, operating system, browser, behavioral data, custom user events, and even data from third-party sources such as Tag Manager, Segment, and Marketo. Customizable selection logic Implement advanced selection logic through AND/OR operators and group conditions using parentheses to build highly-specific segments. Activity-driven user selection Select users to become part of tests based on their historical behavior. Integrate VWO with CDPs and use their historical attributes stored externally to select visitors. Custom user qualification VWO does the heavy lifting to qualify users for a test according to the targeting conditions set. You can choose if VWO has to qualify the visitor every time they land on your site or just the first time.

Optimize experiences by tracking your North Star metrics

Run tests to optimize metrics that matter to your business with VWO’s custom goals. Prioritize metrics your way Set up the primary and secondary metrics from any third party via integrations to determine which variation performs better concerning these metrics. VWO declares a winner based on your primary goal. Use metrics library with just a click Use out-of-the-box options or pull in metrics from the metrics library or a metric cluster to swiftly get started with optimizing critical KPIs. Protect critical metrics performance (Coming soon) Configure critical business metrics under guardrail metrics to ensure tests don’t negatively influence them. VWO automatically pauses tests or notifies you if guardrail metrics get impacted. Inverse winner metrics (Coming soon) Set up inverse winner logic for negative metrics such as crash-rate, and cart-abandonment rate, which should ideally reduce in value. VWO declares winners based on ‘Worse Than Control’ for inverse metrics.

Take data-driven decisions based on statistically valid reports

Accurate reports based on Bayesian Stats that help you and your stakeholders make data-driven business decisions with precision. Accurate results, always VWO's Bayesian-powered stats engine for tests ensures your test results are accurate by handling peeking errors and multiple testing errors. Complete visibility into performance (Coming soon) Improved VWO reports show you the probability to be ‘Better Than Control’, ‘Worse Than Control’, and ‘Practical Equivalence’, giving you enhanced decision-making power. Weed out outliers (Coming soon) VWO automatically detects outlier values in your tests and makes necessary adjustments behind the scenes to ensure your test results never get skewed. Zeroed in, Shareable Insights Filter reports based on out-of-the-box options or custom dimensions. Export reports as CSV, email a link, or forward them to an analytics tool for further analysis.

Rollout variations instantly with zero dependency

Don’t let your winning variations sit idle. Roll them out immediately to maximize conversions. Rollout test winners immediately Every conversion missed is a lost opportunity. No more waiting on developers to release the winning variations to production. Update time-sensitive, business-critical information Critical updates like a phone number change or a price change shouldn’t have to wait. Update such changes in a jiffy.
