Overall Satisfaction with Optimizely Web Experimentation

Optimizely Web experimentation is the primary tool I use to validate front-end and workflow changes. But beyond the day-to-day, I've leaned on it for more ambitious projects like an ongoing experiment with AI-driven diagnostic recommendations. I'm coordinating with our analytics team to pipe experiment data into Power BI. We've also partnered with Kin + Carta to implement a workaround that links Optimizely events with some of our older reporting systems.

Pros

  • Fast iteration on tools with real time reporting.
  • Safe rollouts on high-risk features.

Cons

  • I attempted to test a multi-step referral process across both desktop and mobile, but I couldn't complete it without involving Optimizely experts, as the setup requires a significant amount of custom code.
  • Experiments that increase completion rates directly reduce support tickets saves us money in the tens of thousands.
  • Biggest ROI comes from avoiding sinking dev resources since we can just test first.
While it works well in focused front-end use cases, it starts to show strain when stretched across multiple departments and sites.
It has streamlined the operational loop between product, engineering and analytics. I'm able to show our executives a clean story of hypothesis, test and result without stitching data from multiple systems.

Yes

Would you buy Optimizely Web Experimentation again?

Yes

It worked so well when we wanted to try different client onboarding flows in our referral portal. We ran one test that compared a guided wizard versus a simplified one-page form. Optimizely gave us quick clarity on which version reduced abandonment rates. This is gold in b2b. On the less appropriate side, when we attempted a multi-system experiment tied to our EHR integration, the complexity made it difficult to track accurate outcomes without pulling in external partners.

Using Optimizely Web Experimentation

ProsCons
Like to use
Technical support not required
Unnecessarily complex
Difficult to use
Slow to learn
Cumbersome
Lots to learn
  • Quick UI tweaks without touching the core code. For instance moving buttons to reduce scroll drop-offs
  • Isolating a specific group of users in pilot programs
  • frontend only toggles
  • I've come close to smashing my screen several times while doing conditional rendering
  • any workflow that is multi-step or multi device is clunky
Yes - The mobile ui is somewhat usable for lightweight tasks but I wouldn't rely on phone. Desktop is just way better
