Before you get started with VWO

Describes the conditions that must be met before using VWO.

• To be able to use VWO on your website, make sure that you are able to install the JS code snippet of the VWO SmartCode on your website.
  

  NOTE: VWO only supports domain-name based URLs. If you want, you can 
  set up a sub-account to verify your A/B Tests. Post this, you will be 
  able to clone your A/B tests to your production account.

• As the tag managers are asynchronous, you do not have any control as to when the tag gets triggered. Due to this, a tag might get triggered at last instead of first place. The issue with VWO SmartCode initiating late on the page is that your A/B tests load late on the website. As a result, you will see the control page for a moment before the changes appear. Also, the tag managers have other scripts and if the VWO script in a tag manager works fine for you on your blog pages doesn’t mean that it might be the same for other parts of your website where there are more scripts.
  

  NOTE: In general, all the A/B testing platforms have this issue.

• To use the VWO app, it’s recommended to use the latest versions of Chrome, Firefox, and Safari browsers. To be aware of the domains that have the ability to track users across different websites, refer to ITP issues.
  

  NOTE: In Safari and Firefox (version 67 onwards), the third-party cookies are disabled by 
  default. You need to manually enable them to use Campaign builder, Heatmaps, or Live 
  Previews.
  

• If you wish to run campaigns without writing a single line of code, we recommend you to install the VWO Plugin in your webpages. Plugins in VWO automatically adds the SmartCode to the websites.
