Web Experimentation Certification Track
Track overview
Section titled “Track overview”The Web Experimentation certification track validates your ability to design, implement, and analyze experiments on websites and web applications using Optimizely Web Experimentation. This track covers experiment design, audience targeting, visual editor and code variations, statistical analysis, and personalization campaigns.
Web Experimentation is where many organizations begin their optimization journey. This track ensures you can run experiments that produce reliable, actionable results.
Exam domains and weightings
Section titled “Exam domains and weightings”Foundation (prerequisite)
Section titled “Foundation (prerequisite)”The Optimizely Foundations exam is a single cross-product assessment required before any Core certification. It covers platform-wide concepts across all Optimizely products — not specific to this track. See the Foundations exam overview for domains and format.
