About Optimizely Web Experimentation

Optimizely Web Experimentation is a product for testing changes on websites. Marketers and product teams use a visual editor to build A/B and multivariate tests quickly, and can go deeper with server-side control when they need to test more than what is on the page.

Optimizely now presents it under the heading of agentic experimentation, with AI woven through each stage from idea to decision. The vendor says AI that knows an entire program recommends what to test next, and describes Virtual Teammates that act as a marketing analyst, personalization strategist, CRO manager and chief of staff, handling tasks such as insights, campaign planning and reporting. The messaging stresses running safer tests and validating changes before rollout. It is proprietary and vendor-hosted, with plan details on the Optimizely site.
