Twilio uses Visual Website Optimizer (VWO) to run A/B tests and track visitor behavior, which can temporarily hide page content while experiments load and sets cookies tied to your browsing session.
VWO can modify what content you see on the website based on behavioral profiling and testing, and it sets persistent cookies to track which experiment variations you have been exposed to.
The VWO integration fires a script that hides page body content while settings are loaded, which has potential implications for consent-first cookie deployment under GDPR. Compliance teams should verify that VWO is gated behind the TrustArc consent wrapper and does not set cookies or fire tracking pixels prior to consent being obtained.
