Sentiment Analysis: A crucial tool in digital marketing, sentiment analysis involves the use of natural language processing (NLP) and machine learning techniques to identify, extract, and quantify the emotional tone behind online conversations. This process helps brands to understand consumer opinions and feelings about products, services, or campaigns, enabling more targeted and effective marketing strategies. By analyzing sentiments expressed in social media posts, reviews, and comments, companies can gauge public reaction, monitor brand reputation, and improve customer experiences.
