Build a Personalized Product Recommendation Engine

Use AI to analyze customer behavior, purchase history, and browsing patterns to deliver real-time personalized product recommendations across your e-commerce store.

Time Required

8–12 hrs setup / ongoing tuning

Expected Result

A working recommendation layer that shows personalized product suggestions to logged-in users, increasing average order value and reducing time-to-purchase.

Recommended Tools

1

Export and Structure Customer Data

Export your customer purchase history and browsing data as CSVs. Use ChatGPT to write a data cleaning script that standardizes the format: CustomerID, ProductID, Category, Timestamp, Action (view/purchase/add-to-cart).

2

Build Customer Segments

Feed the structured data into Claude. Ask it to identify 5–8 distinct customer segments based on purchase frequency, category preference, and average order value. Define the segment logic as rules.

3

Generate Recommendation Logic

For each segment, use ChatGPT to write the recommendation logic in plain language: 'Customers in segment A who bought X tend to also buy Y and Z within 2 weeks.' Convert this to a lookup table.

4

Build the API Layer

Use ChatGPT to write a simple Node.js or Python API endpoint: accepts CustomerID, looks up their segment, and returns the top 5 recommended products from your catalog via the lookup table.

Connect to Your Storefront

Integrate the API with your e-commerce platform (Shopify, WooCommerce). Display recommendations in a 'Recommended for You' section on the product and cart pages.

6

Measure and Refine Monthly

Monthly, export click-through and conversion rates for recommendations. Use Claude to analyze which segments and recommendation rules are driving the most conversions and update the logic.
