Why Sentiment Analysis Matters for Amazon Businesses

• Product Strengths and Weaknesses: Pinpoint specific aspects of your products that customers love or dislike.
• Customer Satisfaction: Monitor overall satisfaction levels to identify potential issues early.
• Competitive Benchmarking: Compare customer sentiment towards your products with that of your competitors.
• Reputation Management: Address negative feedback promptly to maintain a positive brand image.
