A/B Testing Case Study

A/B Testing Case Study

SIS International Marktforschung & Strategie


When a Silicon Valley-based enterprise provider faced stagnant conversion rates despite a multi-million dollar ad spend, SIS International was brought in to re-engineer the digital experience. By moving beyond surface-level UI changes and implementing a deep-funnel A/B testing framework, we identified the psychological friction points preventing C-suite engagement.

This study explores how a shift toward “Authority-Driven Design” and frictionless data capture transformed a 1.4% conversion rate into a $3.8M revenue engine.



Case Study: Scaling a US SaaS Enterprise

Client: Silicon Valley-based B2B Software Provider

Objective: Optimize the “Request a Demo” funnel to increase high-intent Enterprise leads.

1. The Diagnostic Phase (The “Friction” Audit)

The client was spending $250k/month on LinkedIn Ads, driving traffic to a demo page. While traffic was high, the lead quality was poor, and the conversion rate from “Visitor to Lead” was stuck at 1.4%.

  • The Insight: Using eye-tracking data, SIS discovered that the “Enterprise” decision-makers were bouncing because the page felt too “Self-Service” and lacked institutional authority.

2. The Hypothesis & Test Design

We moved away from simple color changes and tested Information Architecture:

  • Control: A standard landing page with a long form (7 fields) and generic testimonials.
  • The Challenger (The “Authority” Variant): * Reduced Friction: Shortened the form to 3 fields (Work Email, Company Size, Primary Pain Point).
    • Social Proof: Replaced generic quotes with a “Marquee Row” of Fortune 100 logos.
    • Contextual Validation: Added a “Gartner Magic Quadrant” badge and a “Response Time Guarantee” (e.g., “Talk to an expert in < 2 hours”).

3. The Technical Execution

We implemented Split-URL Testing using a 95% statistical significance threshold. We also integrated Clearbit to auto-populate company data, further reducing the effort required by the user.

4. Results & ROI

  • The Winner: The “Authority” Variant.
  • Quantifiable Impact: 35% more conversions
  • The Revenue Multiplier: Because the lead quality improved (higher percentage of Director-level titles), the Sales-Accepted Lead (SAL) rate rose by 15%, representing an estimated $3.8M in new pipeline value within the first quarter.
