Where is it used?

Sentiment analysis is used in:

1. Campaign performance evaluation — to gauge public reaction to posts or influencer content

2. Brand reputation monitoring — identifying whether online chatter is positive, negative, or neutral

3. Product feedback — analyzing comments and reactions to product announcements or launches

4. Crisis management — spotting spikes in negative sentiment early to take action

5. Influencer selection — assessing audience sentiment towards potential influencer partners

6. Market research — understanding customer opinions in a non-survey-based, real-time way

When to use it?

Use Facebook sentiment analysis when:

• You’re launching a new campaign or product and want to monitor public reaction

• You're managing a brand with frequent user engagement on posts or ads

• You need to evaluate the impact of influencer collaborations

• You’re responding to a public issue or controversy and need real-time feedback

• You want to continuously measure brand health across Facebook conversations

How to use it?

• Collect data from Facebook comments, messages, and reactions (via Facebook Graph API or third-party tools)

• Feed the content into sentiment analysis software (such as Brandwatch, Hootsuite Insights, Sprout Social, or custom-built NLP models)

• The system uses NLP to classify content as positive, negative, or neutral

• Generate sentiment score reports and breakdowns (e.g., percentage of negative comments)

• Monitor trends over time and across content types (organic, paid, influencer)

• Use findings to adjust messaging, content, influencer partnerships, or crisis response
