How Amazon and others Leverage Sentiment Analysis for Customer-Centric Strategies

Updated: Nov 21, 2023

Understanding customer sentiments is crucial in this today's dynamic business world. Customers regularly share their thoughts and experiences on platforms like social media, online reviews, and customer service interactions. Recent events, such as the collapse of Silicon Valley Bank, the first major U.S. bank failure in the digital era, underscore the importance of analysing these sentiments. Market reactions are not solely driven by objective metrics but also by emotional sentiments emphasizing the potential of real-time public sentiment analysis in predicting financial crises earlier than traditional indicators. Real-time public sentiment analysis empowers businesses to swiftly recognize customer preferences and pain points, tailoring their strategies more effectively.

In this article, we will explore how sentiment analysis helps businesses make data-driven decisions and enhance customer relationships.

Understanding Sentiment Analysis

Sentiment analysis, also known as opinion mining, is the process of using natural language processing (NLP) and machine learning techniques to analyse and determine the emotional tone or sentiment expressed in textual data. It involves categorizing text as positive, negative, or neutral based on the language and context used.

Sentiment analysis algorithms examine the words, phrases, and context within a piece of text to discern the sentiment conveyed. For example, a customer's review of a restaurant that says, "The food was delicious, and the service was outstanding!" would be categorized as positive sentiment, while a review that states, "The food was terrible, and the service was slow" would be categorized as negative sentiment.

The Importance of Customer Opinions

Customer opinions are a valuable source of information for businesses. They provide insights into customer satisfaction, preferences, pain points, and expectations. By analysing customer sentiments, businesses can:

  • Product and Service Enhancement: Customer feedback highlights areas for improvement. Positive sentiments reveal strengths, while negatives signal areas needing attention.

  • Targeted Marketing: Understanding sentiment enables tailored marketing campaigns. Positive sentiments showcase strengths, while addressing negatives bolsters brand perception.

  • Improved Customer Support: Apply sentiment analysis to support interactions for quick issue resolution and enhanced customer experiences.

  • Competitive Edge: Monitor sentiment trends about competitors to identify market gaps and seize competitive advantages.

  • Brand Health Assessment: Track sentiment over time to gauge brand health and measure the impact of marketing and PR efforts.

How Sentiment Analysis Works

Sentiment analysis is a form of natural language processing (NLP) technology that teaches computer software to comprehend text akin to humans. The process involves several stages:

1. Pre-processing: In this initial stage, key words are identified to capture the text's essence.

  • Tokenization: Divides sentences into tokens or elements.

  • Lemmatization: Converts words to their root form (e.g., "am" to "be").

  • Stop-word Removal: Filters out non-meaningful words (e.g., "with," "for," "at").

2. Keyword Analysis: The extracted keywords are further analysed using a sentiment score, a measurement scale representing the emotional aspect in sentiment analysis. This score provides a relative assessment of the expressed emotion for analytical purposes. For instance, a score of 10 signifies satisfaction, while 0 indicates disappointment in customer reviews analysis.

Data Sources for Sentiment Analysis

Data for sentiment analysis can be sourced from various channels, including:

  • Social Media: Platforms like Twitter, Facebook, and Instagram are rich sources of customer opinions and emotions.

  • Online Reviews: Customer reviews on websites like Yelp, Amazon, and TripAdvisor provide valuable sentiment data.

  • Surveys: Customer surveys can include open-ended questions that yield textual data for sentiment analysis.

  • Call Centre Transcripts: Analysing customer service call transcripts can reveal sentiment patterns and areas needing improvement.

Case Studies: Transforming Brands and Products Through Sentiment Analysis

KFC: A Model for Brand Transformation Through Sentiment Analysis

KFC provides a prime example of effectively applying sentiment analysis for brand building and monitoring. While competitors were evolving towards narratives of health and positivity, KFC chose a different route, leveraging its well-established brand identity.

Rather than attempting to carve out a niche in a crowded market, KFC capitalized on the widespread recognition of its brand. They incorporated elements from popular culture, such as iconography and memes, to convey their brand's unique value proposition. This strategy naturally generated brand traction, fortified by pop culture references, enticing users to engage with the brand and, subsequently, its products.

Sentiment analysis played a crucial role in enabling KFC to swiftly respond and adapt to evolving trends in real-time.

Google's Approach to Product Enhancement

Google exemplifies the impact of sentiment analysis on product improvement, as seen with the Chrome browser. Google Chrome's development team actively tracks user feedback, whether direct or indirect, often derived from open sources like blogs.

They deconstruct user feedback into its constituent elements, including sentiment (positive or negative), mentions of specific product aspects like scalability, extensions, security, and user interface, as well as broader sentiments, desires, and suggestions concerning the product and its individual components. This comprehensive analysis allows Google to make informed refinements to their product.

Amazon, the global e-commerce giant, demonstrates the power of sentiment analysis by meticulously assessing a vast array of customer reviews.
