How Businesses Use Sentiment Analysis

Sentiment analysis helps businesses understand how customers feel about their brand, giving them first-hand information to improve their products, make data-driven decisions, and deliver better customer experiences. 

At the same time, sentiment analysis adds intelligence to everyday processes, enabling a more strategic approach to customers based on their emotional response.

Let’s take a look at some of the most common sentiment analysis use cases: 

Social Media Monitoring

Companies are increasingly using sentiment analysis tools to monitor social media conversations, and gain real-time insight into customers’ preferences, opinions, and experiences with brands.

Sentiment analysis allows you to identify frustrated or angry customers on the fly, and respond to negative interactions right away. Being able to identify a crisis situation fast allows you to take immediate action and protect your brand’s reputation. 

You might also want to track customer reactions to specific events, from a product launch to your latest marketing campaign. Using aspect-based sentiment analysis tools, you can home in on specific topics in social media conversations. This approach also allows you to Learn what customers like and dislike about your product: what do they think about your customer service? What are their favorite features? 

Customer Service

Waiting too long for a response is the #1 cause of customer frustration. One of the ways businesses can improve their response times is by automating the task of tagging incoming support tickets.

Your customer service team can use sentiment analysis to tag incoming tickets based on their emotional tone, and automatically send negative tickets to the top of the queue. That way, you can be sure that the most urgent issues are being handled first. 

At the same time, you can create rules to automatically route tickets. For example, you could assign tickets from angry customers to the most experienced reps on your team, to guarantee they get the best attention. 

Market Research

Sentiment analysis can help businesses uncover trends and explore new market opportunities. 

If you are planning to launch a new product, you might want to track sentiment relating to specific topics or words on social media.  This is a great way to gain insights about what your customers need, as well as their preferences. 

In a similar way, you can use sentiment analysis to analyze product reviews from your competitors and find out how customers feel towards every aspect of their business. What are they doing well? What are their weak points? Using this data can help you make strategic business decisions. 


Sentiment analysis makes sense of the data you already have and reveals powerful insights that help you understand how customers feel about your brand. 

With MonkeyLearn, you can use pre-trained models right away or create your own customized tool for sentiment analysis in just a few minutes.
