The VWO SmartCode fetches tweaked experiences directly from our CDN servers, and instantly manipulates the DOMs or the HTML.

self-upgrading icon


Once the VWO SmartCode is deployed on your website, you are not required to change it to access new features developed by VWO, which happens very often. The VWO SmartCode gets you all the new and old features of the powerful platform on its own. No requests needed for access to new features, no code changes required.

One-time deployment

VWO SmartCode is to be installed on your entire website only once, and for all pages of your website—a universal deployment. The <Head> section is the same across the entire website, so the VWO SmartCode will be present automatically on new pages too! For third-party plug-in-based setup also, new pages will have the VWO SmartCode as long as your configuration does not have any specific exclusion rules. You don’t need to install the VWO SmartCode multiple times to utilize any of VWO’s capabilities to the fullest or for each test you run—VWO SmartCode will manage that for you.

Enhanced privacy control

Once VWO SmartCode is integrated with your website, all requests originating from it can be routed to your own server, before being proxied to the VWO Server. This creates an extra layer of security and gives you complete control over the data sent to the VWO Server. Plus, you also avoid those annoying disruptions from ad blockers and run your optimization program without compromising user privacy.
