The short answer

VWO is an A/B testing script from Wingify (VWO). Suitcast rates its risk under the California Invasion of Privacy Act, CIPA, as medium, because complaints describe scripts like it recording visitors before they consent. The fix is to load it only after a visitor accepts, or to remove it when it is not used.

Why complaints name it

Complaints describe it as tracking a visitor's clicks and, when recordings are on, their session, before the visitor agreed.

The act allows $5,000 per violation, which is why firms look for scripts that run the moment a page opens.

The fix

How to stop VWO firing before consent

Written for the person who runs the site, with the setting to change.

  1. In VWO settings, turn on the option to wait for consent and connect it to your banner or Google Tag Manager consent mode, and turn off session recordings unless you review them.

  2. Remove the script if you finished testing.

How the scan checks this

  1. Loads your pages like a first visit. A real browser, nothing clicked, nothing accepted.
  2. Checks every request before the banner is answered. A request to dev.visualwebsiteoptimizer.com is matched to VWO and recorded with the millisecond it fired.
  3. Clicks reject and watches again. When the banner has a reject button, the scan presses it; if VWO keeps firing, the report says so.

Scanner rules and limits are on the methodology page.

Questions owners ask

Whether VWO is a problem, how to check your site, and where the counts come from.
Is having VWO on my site illegal?
No. The complaints do not claim the script is illegal; they claim it recorded a visitor before the visitor consented, or kept recording after the visitor declined. Loading VWO only after consent, or removing it when it is not used, is what removes the pattern the complaints describe.
How do I know if VWO fires before consent on my site?
Run the free scan. It loads your pages without clicking anything and checks every request that leaves the browser against its tracker catalog, recording the millisecond each match fired. If VWO appears, it fired before consent. When your banner has a reject button, the scan clicks it and reports whether the script kept firing.
Where do the case counts on this page come from?
From the complaint text of verified California Invasion of Privacy Act filings. When a complaint names this script, the case is linked to it. Complaints that are not yet available in the public record are not counted, so the number is a floor.

Does VWO fire before consent on your site?

The free scan checks every request your pages make before the banner is answered, shows the millisecond VWO fired, and whether it kept firing after reject.
