Maximize the success of your production rollouts by setting up simulated environments for project-specific testing.
Efficiently manage features and feature variables for testing by releasing them behind flags with on/off toggle switches.

VWO’s asynchronous SmartCode loads page changes asynchronously when the web page loads, reducing page load time.
Create advanced webpage variations with pop-ups, forms, and more with the widget library and code editor.
Use A/B testing, Split, or Multivariate tests to optimize conversions by testing elements or combinations against each other.

Extensive audience selection options with your user data to run tests the way you want.
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.
Implement advanced selection logic through AND/OR operators and group conditions using parentheses to build highly-specific segments.
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.
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.
Run tests to optimize metrics that matter to your business with VWO’s custom goals.
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 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.
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.
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.
Accurate reports based on Bayesian Stats that help you and your stakeholders make data-driven business decisions with precision.
VWO's Bayesian-powered stats engine for tests ensures your test results are accurate by handling peeking errors and multiple testing errors.
Improved VWO reports show you the probability to be ‘Better Than Control’, ‘Worse Than Control’, and ‘Practical Equivalence’, giving you enhanced decision-making power.
VWO automatically detects outlier values in your tests and makes necessary adjustments behind the scenes to ensure your test results never get skewed.
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.
Don’t let your winning variations sit idle. Roll them out immediately to maximize conversions.
Every conversion missed is a lost opportunity. No more waiting on developers to release the winning variations to production.
Critical updates like a phone number change or a price change shouldn’t have to wait. Update such changes in a jiffy.
Spotted a hyperlink error, a wrong spelling or a formatting issue? Fix them immediately without the back & forth.
Feature rollout enables you to test everything in the beta stage. You can test and release features in a phased manner to specific segments.

Build a Kanban board workflow with observations to feed your testing and personalization campaigns. Add team members without restrictions and run your optimization program like a breeze.
The VWO-Contentful Integration was the biggest feature that appealed to us. We previously used engineering resources to launch every server-side A/B test. Given our team’s large ambitions and limited engineering resources, we could only launch ~1 test every 14-20 days. With the VWO-Contentful integration, we removed the engineering dependency for setting up and launching front-end experiments.

VWO is competitively priced and has a good product offering. It has offered the team here at Digital NRG a great level of insight into customer behavior on our client websites and has allowed us to run a great number of tests. They also have a very responsive team, who are very helpful and take feedback on board when it is needed.

I really like that we can use VWO across every department. It's pretty easy to use and straightforward. Test results are easy to read also for people who don’t have testing experience. Testing experience with VWO was quite intuitive for all. UX of the tool was quite accessible as well.

VWO worked PERFECTLY. It enabled us to make all the changes we wanted rapidly, prove the value of our tests, and grow our client’s sitewide conversion by over 30% in a matter of months. We could not have achieved such growth without VWO.

CRO Lead at Digital NRG
The earlier A/B Testing platform that we had was limiting, in the sense, we couldn’t get deep into the experimentation culture, we had no control over the process, the analysis wasn’t as actionable as we would like, leaving us thinking if we should go live with a test or not. For us, VWO is not just an A/B testing tool, but a comprehensive website utility tool.
UX and Web analyst at Eastpak
VWO is a highly user-friendly and economical tool. It offers an intuitive user interface. It makes it easy to run experiments, gather customer insights, check for leakages in the sales funnels, looking at customer journeys using recordings, and conducting usability tests. The ease of segmenting the audience while creating ‘control’ and ‘variation’ is also something that makes VWO stand out.
Team Lead Conversion & CRO Consultant
My overall experience with VWO has been positive, especially with the fast response to questions and support requests.
CRO Manager
Every A/B testing process aims to bring a significant raise in the conversion rates, and for a SaaS website like POSist which targets niche restaurant industry, this was a 4 month long journey. After months of rigorous testing in between multiple variations of our website with VWO’s Split URL testing campaigns, we were able to register a 50% growth in our organic leads.
Cofounder and CEO
It has been an exciting journey for us with VWO. The collaborative approach of the VWO Services team allowed Utsav Fashion to implement many features on our website based on customer behavior insights. The project forced us to deeply understand customer behavior and innovate fast. We successfully discussed, designed, and implemented a number of campaigns on their merit. I believe all these will help our customers immensely and make their buying journey enjoyable.
