How to Build a Predictable Growth Engine: A Step-by-Step Guide

Building a predictable growth engine involves a structured approach that focuses on data analysis, strategic optimization, and continuous improvement. Here’s a step-by-step guide:

Step 1: Define Your Key Performance Indicators (KPIs)

Start by identifying the most critical metrics that reflect your business performance. Focus on a select few KPIs that directly impact your bottom line. Examples include:

Customer Lifetime Value (CLTV): The predicted revenue a customer will generate throughout their relationship with your business.
Average Order Value (AOV): The average amount spent per order.

Dive deep into your data to understand the factors influencing your KPIs. Use eCommerce analytics tools to:
