🧠 The Beginner’s Guide to Writing Landing Page Copy with AI

Using Supergoop! as a Real-World Example

Learn how to build a high-converting landing page using AI — even if you’ve never written copy before. This guide walks you through every section, shows you how to prompt effectively, and uses a well-known brand (Supergoop!) as a real-world reference to bring each step to life.

📦 Step 1: Fill Out Your Product Brief

Before you prompt anything, you need a clear snapshot of what you’re selling. This will help the AI produce accurate and relevant responses.

Answer these four questions:

• What is the product?
  e.g., A weightless, invisible SPF 40 sunscreen

• Who is it for?
  e.g., People who wear makeup and want clean sun protection

• What makes it different?
  e.g., Doubles as a primer, no white cast, clean ingredients

• What’s the offer?
  e.g., Free shipping on first order; Subscribe & Save 15%

👋 Prep Your AI: Feed It the Product Brief First

Before using any of the prompts below, give your AI the product brief so it understands your context.
