Run complex experiments and feature changes
With VWO FullStack, you can literally test anything, be it subscription flows, search algorithms, or any idea that can move your north star metric. Leverage our rich feature set with multi-platform testing, mutually exclusive testing, goal tracking, targeting, scheduling, and more, to optimize product experiences.
Leverage our advanced reporting and segmentation
Slice and dice test results to discover hidden winners and measure their impact across the funnel. Find out if a specific visitor segment converted drastically different than the others for a specific goal or variation, and use the learnings to optimize features on the go.
Confidently rollout features with minimal risk
Mitigate risk by safely delivering a new feature to a small group of targeted audience before making it live. This enables the product team to control the feature rollout and measure the impact on users, while the development team can seamlessly deliver the feature and monitor the effect on the backend.
No impact on performance. Say goodbye to flickering.
We understand the impact of every microsecond, and with VWO FullStack's server-side testing, the flickering effect is eliminated. With pre-determined experiment variations that are not served on the fly through the browser, the experiment is unnoticeable to the website visitor and has minimal impact on page load time.
Advantages of server-side testing with VWO
Run complex experiments rendered directly from your server and premeditatedly send variations to a visitor's device.
Decouple deployment from release by creating flags, managing them at runtime, and choosing which user gets to see which feature.
Mitigate risk by safely releasing new features to a small audience before going live.
Test different feature configurations to determine the variant which delivers the best experience.
Set your own user IDs to create consistent personalized experiences across all your customer channels for that user ID.
Split traffic between multiple versions of your website and choose the percentage of visitors to be included in your experiment.
Slice and dice your test results to uncover hidden winners. Understand how differently visitor segments convert.
Quickly assure quality of experiments by driving specific users or user segments into particular variations.
Our SDKs are open source and ensure that user data is never pushed in VWO servers.
Easily integrate the VWO SDKs and get started in 15 mins with minimum performance impact.
Run multiple experiments on your home page or in-app while ensuring that visitors remain part of a single variation. The data collected for one test will never be affected by any other test.
Get notified whenever there is a change in campaign settings with Webhooks, and receive change event notifications.
Ensure visitors remain bucketed in their respective variations and maintain experience continuity.
Creating individual projects lets you manage and track multiple business experiments simultaneously.
Manage campaigns across development, testing and production environments.
Increase accuracy by creating custom segments to target a specific audience and reduce repetition by saving that segment for later use.
Bayesian SmartStats Engine
SmartStats, our Bayesian statistics engine, 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 important business goals.
SmartStats is as sophisticated and as easy as you want it to be. While giving you easy-to-digest recommendations and metrics; our advanced reporting mechanism can help you slice and dice to understand each and every aspect of our recommendations.
Frequently Asked Questions
Server-side testing is a method of A/B testing wherein the variations of a particular test are rendered directly from the web server & then deliberately sent to the visitors’ device.
Client-side testing is used when an optimization test involves delivering variations of a webpage that rest on the visitors’ browser. Server-side testing allows tests to be run and modifications to be made directly on the web server & then render the same to the visitor’s browser or mobile app.
An eCommerce store owner, with an aim to optimize for better conversions, wants to test two different checkout flows on both his/her website & mobile app at the same time. As this is not possible by running a simple A/B experiment on the client-side, Server side optimization is required. This type of optimization is more robust and is built for fairly complex tests.
Server-side A/B testing requires a one-time VWO SDK installation, which is integrated into your server application. Whenever a visitor lands on the client browser, a call is sent to the backend server, where the SDK of the server-side testing tool is installed. These settings are then used to create a client instance of SDK, which offers various capabilities like A/B testing by providing a variation to a particular user.
