- The code snippet you add to your website pages contacts the VWO server whenever a visitor lands on a page where the VWO code is running.
- The VWO’s CDN decides which ones out of all the active tests are relevant for this page.
Note: If a test will actually run or not, it is computed in real-time on the visitors' browser.
- The response from the server determines which DOM element on the control version should be replaced in the variations. For clicks, form submissions, or engagement goals, a VWO function binds the click event on the page that checks if a conversion has occurred.
- The website is rendered after the implemented changes are loaded onto the website, to be displayed to your visitors. All this happens in milliseconds behind the screen.
