Questions you might have

Agentic Experimentation is a smarter way to run experimentation programs with AI. It helps teams move faster across the full experimentation lifecycle, from generating test ideas and prioritizing opportunities to building variations, checking quality, analyzing results, and deciding what to do next. 

Agentic Experimentation supports both web experimentation and feature experimentation. Web experimentation helps teams test and optimize digital experiences on the front end, while feature experimentation helps product and engineering teams test server-side changes, manage feature flags, and roll out new capabilities safely. 

Yes. Optimizely is designed to work with the tools teams already use across marketing, product, engineering, analytics, and content workflows. This helps teams connect experimentation with the broader digital experience stack rather than working in silos. 

Agentic Experimentation helps teams improve both speed and quality. It can surface stronger test ideas, turn insights into structured plans, help create variations faster, support QA, and recommend next steps based on results, so teams can spend less time on manual work and more time driving impact. 

Both. Marketers can use Agentic Experimentation to generate ideas, build stronger test plans, understand results, and move faster from insight to action. Developers can use it to support more technical experimentation workflows, including feature experimentation, server-side tests, flags, and controlled rollouts. 

Agentic Experimentation helps teams identify, launch, and learn from the tests most likely to improve customer experiences. By focusing experimentation on higher-impact opportunities, teams can optimize the journeys that influence conversion, engagement, and revenue. 

Yes. Agentic Experimentation can help teams understand which experiences work best for different audiences, then use those learnings to create more relevant customer journeys. It helps teams move from broad testing to smarter, evidence-based optimization. 

Yes. Agentic Experimentation can help teams identify high-potential opportunities by using behavioral signals, past experiment results, and performance data. Instead of starting every cycle with guesswork, teams can prioritize ideas based on evidence.
