Introduction

Product reviews reflect real consumer experiences and strongly influence future purchases. Platforms like Amazon, Walmart, and Target provide thousands of reviews daily—yet few brands leverage this data for predictive product planning and trend forecasting.

A U.S.-based CPG brand collaborated with Actowiz Solutions to deploy a review sentiment analysis engine across multiple platforms, using customer language to predict satisfaction, identify feature gaps, and prioritize product improvements.

Objectives

The-Client
  • Collect and analyze reviews for 200+ SKUs across Amazon, Walmart, and Target.
  • Classify review sentiment (positive/negative/neutral) using NLP.
  • Detect recurring product complaints, praise themes, and usage patterns.
  • Predict product performance trends by category and geography.

Challenges

The-Client
  • Reviews differ in language style, length, and slang across platforms.
  • Some platforms mask or batch-review data requiring deeper parsing.
  • Sentiment polarity often doesn’t match star ratings (e.g., 4-star but negative text).

Actowiz Solutions’ Approach

The-Client
1. Multi-Platform Review Extraction:
  • Scraped review data using dynamic parsing from:
    • Amazon product pages (verified & non-verified)
    • Walmart reviews API
    • Target web scraper with star-wise filters
2. NLP-Based Sentiment Engine:
  • Pre-processed text using tokenization, lemmatization, and stop-word removal.
  • Used VADER and TextBlob, along with custom-trained LSTM model.
  • Scored reviews as:
    • 🟢 Positive
    • 🟠 Neutral
    • 🔴 Negative
3. Theme Clustering:
  • Extracted keywords and common phrases (e.g., “leaks,” “great flavor,” “too small”).
  • Clustered sentiments around key product attributes

Sample Output

Platform SKU Rating Sentiment Key Phrase Volume
Amazon Protein Bar A 4.5 🟢 Positive "great taste" 1,124
Walmart Detergent X 3.9 🔴 Negative "leaked in package" 328
Target Cereal B 4.1 🟠 Neutral "too sweet" 211
