Wingify, the company producing Visual Website Optimizer (VWO) tool, has recently developed a new "Asynchronous" tagging code to be used in websites that are tested using VWO.
An asynhronous tagging code snippet is just like the regular Visual Website OPtimizer tracking code. However it has some benefits over the old one.
- Faster tracking code load times for your web pages
- Enhanced data collection & accuracy
- Elimination of tracking errors from dependencies when the JavaScript hasn't fully loaded
This also means that if you are using asynchronous code then your website will not be having loading issue due to the Visual Website Optimizer tracking code. The new asynchronous version of Visual Website Optimizer code reduces page load time as the VWO code is downloaded in parallel to site code.
It also ensures that your site is never slowed down even if VWO servers are inaccessible.
Wingify have extensively tested the asynchronous code across variety of browsers (including IE7) and it works perfectly. Though they are keeping this code currently in beta until they get feedback from users that it is indeed a significant improvement over existing Synchronous code.
