Optimizely experimentation that your roadmap can rely on.

A licence without a calendar.

An Optimizely licence earns its cost through the tests you run. An empty calendar wastes it.

What's included

More tests. Better ones.

We run the loop that turns an Optimizely licence into decisions: research, build, launch and read.

Keep a hypothesis backlog

Ideas from analytics, research and your team, written as testable hypotheses and ranked by evidence, expected impact and build effort.

Build and launch tests

Variants built in Web or Feature Experimentation, checked, and launched with primary and secondary metrics already in place.

Read results with Stats Engine

We interpret significance, confidence intervals and false discovery rate control, so a win is real and a flat result still teaches something.

Report on the programme

A monthly view of tests run, win rate and changes shipped, so leadership sees what experimentation returns.

Security, by consideration.

Trust is part of the build.

For your Optimizely project, we consider publishing access, experiments, audience data and connected services as part of one connected build.

Connected systems. Considered safeguards.

Changes you can trace.

GitHub workflows, peer review and dependency checks bring decisions into the release process.

Protected in transit.

Certificate configuration, HTTPS and secure headers help protect the path between your users and your systems.

Intelligence with limits.

Scoped tool access, validated inputs and human approval where automated actions carry consequences.

The testing loop.

Three steps, repeated every cycle, sharper each time.

Optimizely experimentation questions.

A few things worth discussing before your Optimizely experimentation takes shape.

Can Stega run our whole Optimizely experimentation programme?

Stega can run your Optimizely experimentation programme on the website and product side: ranking hypotheses, building variants, launching tests and reading results. We work inside your account, beside your product and marketing teams. For Optimizely CMS builds or a full digital experience platform rollout, a specialist Optimizely partner is the better fit.

How does Optimizely Stats Engine decide a winner?

Optimizely Stats Engine decides a winner with sequential testing, so you can check results while a test runs without inflating false positives. Stats Engine also controls the false discovery rate across metrics and variants. A result counts once it passes your project's significance level, which defaults to 90%.

How many tests should we run in Optimizely each month?

The number of Optimizely tests you can run each month depends on traffic, not ambition. Each test needs enough visitors to reach significance, and tests on the same page need exclusion groups or careful planning. We size the calendar from your traffic, so every test has a real chance of an answer.

How long before an Optimizely testing programme shows results?

Early tests target high-traffic pages so you learn fast. Programme value builds over quarters, as each result shapes the next test, so we report on the programme as well as on single tests.
