There are many tools and methods to monitor public sentiment, depending on your goals, budget, and resources. Social media listening is a common approach that involves using platforms such as Twitter, Facebook, Instagram, LinkedIn, and YouTube to track conversations about your brand or industry. You can use hashtags, keywords, mentions, tags, comments, likes, shares, and reviews to gauge the volume, tone, and sentiment of the conversations. Media monitoring is another approach that involves using platforms like Google Alerts, Meltwater or Cision to track media coverage related to your brand or industry. Survey and feedback is a third approach that involves using platforms like SurveyMonkey or Qualtrics to collect opinions and preferences from your audience. Automation tools like Hootsuite, Sprout Social or Mention can streamline social media listening. Other tools such as BuzzSumo or Moz can measure the reach and impact of media outlets and articles. Finally, metrics such as Net Promoter Score (NPS), Customer Satisfaction Score (CSAT), or Customer Effort Score (CES) can quantify customer loyalty or happiness.
