Why Experimentation Isn’t Just for A/B Testing Anymore

Experimentation isn’t new. But how we define it and use it have evolved dramatically. What once was a simple “A/B test” on a landing page has become a business-critical strategy spanning product development, customer experience, and growth marketing.

Still, lots of teams only scratch the surface. That’s why Optimizely offers a full ecosystem of tools to support experimentation, beyond just split tests. In this post, I’ll explore what modern experimentation really looks like, how it aligns with core business frameworks, and why your team should guide it with the following prompts:

“I wonder…What if…Let’s try.”

These three prompts are at the heart of any good experiment. However, to make experimentation effective at scale, you need more than curiosity. You need dependable data, a strong process, and the right MarTech.

Data — Reliable Tracking, Meaningful Metrics, and Actionable Insights

Before you can trust any test, you need a foundation of high-quality data. That means:

• Clear definitions for success metrics
• Consistent, privacy-compliant tracking
• Real-time data access and post-test analysis

Optimizely’s Data Platform (ODP) plays a central role in establishing this foundation. It connects customer behavior across channels, enabling audience segmentation and event-level targeting that drives smarter testing. ODP doesn’t just collect data, it turns that data into insight.

Other tools like GA4, Mixpanel, or Adobe Analytics support data collection, but ODP uniquely integrates with Optimizely’s testing and personalization engines to close the loop, from idea to outcome.

Process — A Structured Approach with Ownership, Goals, and Governance

Performing one test is easy. Running 50 meaningful ones across teams and touchpoints? That requires structure.

A mature experimentation program includes:

• Clear ownership and prioritization
• Hypothesis-driven design
• Documentation and sharing results
• Guardrails for ethical use and customer experience

This mindset aligns with experimentation tools across the Optimizely suite. Each serves a unique purpose, but works better when governed by a shared strategy. It also reflects the “Sesame Street” moment I’ve written about before. When we slow down and simplify the process, it becomes easier to understand and scale.

MarTech – The Right Tools to Deploy and Scale Experimentation Effectively

Optimizely offers many ways to experiment. Several distinct tools in the Optimizely marketing stack support test-and-learn approaches across channels, teams, and use cases. I’ll tell you more about them.

Web Experimentation

Test visual changes on your site, copy, layout, images, or calls-to-action (CTAs), without touching code. Web Experimentation is ideal for marketers and conversion rate optimization (CRO) teams.

Feature Experimentation

Roll out new features behind flags, test backend logic, and experiment safely within your codebase. Feature Experimentation is loved by product and dev teams.

Performance Edge

Run client-side experiments without slowing down your site. Performance Edge is a great option for high-traffic sites or those with performance needs.

Personalize

Deliver tailored content or a user interface (UI) based on user traits, behaviors, or segments, powered by rules or machine learning.

Product Recommendations

Surface smart product suggestions based on browsing, purchase history, or similar user behavior. Product Recommendations is great for commerce and upsells.

Content Intelligence & Content Recommendations

Use machine learning to understand which content themes, topics, and formats perform best, and apply those insights in real time. It can also suggest articles, blogs, or media based on user interest. Content teams use this tool to drive engagement and lower bounce rates.

Optimizely Data Platform (ODP)

Unify customer data, create rich segments, track event-based behavior, and push audiences to other Optimizely tools or platforms like email, ads, or customer relationship managers (CRMs).

Where Optimizely Fits Among Other Players

The experimentation space has many powerful tools, each offering its benefits depending on your team size, goals, and technical maturity.

Platforms like VWO, AB Tasty, CrazyEgg, and Monetate are solid for teams just starting in CRO or looking for lightweight testing. On the enterprise side, Adobe Target and Dynamic Yield offer broader personalization engines with some testing baked in.

What sets Optimizely apart isn’t just flexibility or its stats engine (though both are excellent), it’s how deeply interconnected the suite is. With experimentation, personalization, recommendations, and customer data all in one place, teams can move faster, test smarter, and act on insight in real-time.

You don’t need to juggle six vendors to run six kinds of tests.

Beyond “A/B”: The Real Power of Connected Experimentation

While most platforms focus on singular testing functions, Optimizely’s strength lies in how its tools connect. You’re not just testing buttons. You’re optimizing end-to-end customer journeys, personalizing at scale, and learning continuously.

When these tools align with a solid data layer, a repeatable process, and modern MarTech, teams can build what we call an experimentation culture. One where questions like:

• “What if we changed the order of steps?”
• “Would this content work better for new users?”
• “Does this feature help or hurt conversion?”

…become part of everyday work, not just one-off tests.

From “What If” to “What Works”: Turning Curiosity into Customer Impact with Optimizely

The other day, my 5-year-old son asked, “Dad… do you really talk about Sesame Street with your customers?”

I told him, “Yeah, I do. The lessons in that show, about curiosity, trying new things, asking ‘what if’, they really apply everywhere.”

That’s the heart of experimentation. Whether you're teaching kids how to count or helping a marketing team improve conversion rates, it all starts with a simple mindset:

I wonder…What if…Let’s try.

Combining this mindset with dependable data, a structured process, and the right MarTech, like the tools Optimizely offers, can uncover valuable insights from your experimentation that you can use to transform your customer experiences.
