By Corey Haines (Marketing)

Plan and run experiments to find out which version of your page, email, or ad works best.

Marketing Copywriting

By Corey Haines (Marketing)

Write compelling website copy that converts visitors into customers.

A/B Test Setup

• Helps you write a clear hypothesis for what you're testing and why
• Calculates how much traffic and time you need for statistically valid results
• Guides you in choosing primary, secondary, and guardrail metrics to track
• Explains how to design test variants that isolate a single meaningful change
• Analyzes results and tells you whether the difference is real or just noise

Marketing Copywriting

• Writes clear, compelling copy for homepages, landing pages, pricing pages, and feature pages
• Crafts headlines, subheadlines, and call-to-action buttons that drive conversions
• Focuses on benefits and customer language instead of jargon and features
• Provides multiple headline and CTA options with explanations for each choice
• Structures page copy to address objections and guide visitors toward action

• You're tweaking email copy or button text and need to measure impact objectively
• You want to build a growth experimentation program and run tests continuously
