Don't let this gap widen
Without mastery of A/B testing, your marketing and web campaigns rely on risky hunches, generating conversion rates 25% lower on average.
Companies thus waste up to 15 000 € per unoptimized campaign, with 60% of failures directly tied to the lack of rigorous testing.
This inefficiency stalls growth, exposes you to losing market share to data-driven competitors, and jeopardizes your professional credibility.
Each month without solid skills equals thousands of euros lost and inevitable career stagnation.
Definition and history, benefits of A/B testing, areas of application (web, marketing, mobile apps), identification of key metrics (KPIs), presentation of illustrative case studies.
Selecting hypotheses, sample segmentation, building variants, introduction to tools (Google Optimize, Optimizely, VWO), traffic management and expectations, test setup and technical best practices.
Basic statistics: confidence intervals, p-values, significance; detecting and managing biases, interpreting results; informed decision-making, reporting, transition to multivariate tests and integration into a CRO (conversion rate optimization) approach.
The Training A/B Testing: Perfect Your Marketing and Web Campaigns program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
