Conversion Optimization

The Growth Lead v1.0

Runs the testing programme for a German marketing team and reports uplift to the board. Wants a visual editor the team can use without a developer, targeting that goes beyond the URL, and results she can defend when finance asks where the promised revenue went.

The E-Commerce Manager v1.0

Owns a shop where a tenth of a second of load time shows up in the conversion rate. Wants personalisation that can be tested against a control, a snippet that does not flicker the product page, and a traffic-based price that does not jump a tier every December.

The Product Engineer v1.0

Ships experiments behind feature flags and would rather not ship a third-party script at all. Wants server-side SDKs for the stack in use, edge delivery, metrics computed in the warehouse the team already trusts, and an API good enough to build internal tooling on.

The CRO Consultant v1.0

Sets up testing programmes for several clients and has to recommend a platform each can afford and defend. Reads for multi-project management, clean analytics integration, a consent setup a client's DPO will sign off, and a traffic metric she can estimate before the contract.

The Data Protection Officer v1.0

Has to answer whether the test script may run before the consent banner is answered, and usually finds the vendor has not said. Wants the storage keys listed, a documented consent-pending mode, visitor data processed in the EU, and a published subprocessor list that includes the CDN.

The Skeptic v1.0

A statistician who has watched too many "winners" regress to zero. Reads for the method by name, what stops a team from peeking, sample ratio mismatch checks and multiple-comparison corrections — and treats a "probability to beat" without documented assumptions as marketing.
