Facebook Sentiment Analysis: How To Do It? [5-Step Guide]
With over 3 billion monthly active users, Facebook generates massive volumes of brand mentions every day. Facebook sentiment analysis lets you cut through the noise and understand whether (and why) people love, criticize, or ignore your brand. Here’s a step-by-step guide to do it the right way.
Key takeaways
-
Sentiment analysis reveals how people feel about you
By analyzing Facebook posts and comments, you can understand audience emotions, spot trends, and detect potential crises early.
-
AI tools are essential for scale and accuracy
Manual analysis works only for small volumes, while AI-powered tools track thousands of mentions, including untagged ones, in real time.
-
Continuous monitoring turns insights into action
Regularly tracking sentiment helps you improve communication, respond to issues faster, and focus on what drives positive perception.
What is Facebook sentiment analysis?
Facebook sentiment analysis is the process of analyzing posts, comments, and other user interactions to determine whether they express a positive, negative, or neutral attitude toward a topic, brand, or product.
Simply put, it answers the question: how do people really feel about you on Facebook?
On a deeper level, it helps determine public opinion, spot emerging trends, improve customer service, and track brand reputation over time.
With 3.07 billion monthly active users in 2026, even a small shift in Facebook sentiment can signal a big opportunity. Or an upcoming crisis.
How to do Facebook sentiment analysis?
There are only two ways to do the Facebook sentiment analysis: the basic one and the right one.
Okay, just kidding! Both methods can work well. It all depends on the size of your online presence.
Manual method
Create a spreadsheet, log every Facebook mention of your brand, and tag each one as positive, negative, or neutral. This works if you have a small online presence – say, under 100 mentions per month.
The downside?
You’ll surely miss untagged mentions, so the ones where people talk about your brand without tagging you. Those are often the most honest (and the most critical).
AI-powered sentiment analysis tools
For brands with a significant online presence, AI-powered sentiment analysis tools are basically the only practical option. They process thousands of mentions in seconds and classify sentiment automatically.
Consider Red Bull: with over 1,800 Facebook mentions per month, manual analysis would take days. An AI tool handles it in minutes.
| Feature | Manual method | AI sentiment analysis tool |
| Speed | Hours/days | Seconds |
| Accuracy | Subjective | AI-consistent + human review |
| Untagged mentions | No | Yes |
| Scale | Up to 100 mentions / month | Unlimited |
| Sarcasm detection | Yes (if reader can recognize it) | Improving with AI + human layer |
| Additional analytics | None | Topics, influencers, trends, etc. |
| Pricing | Free | Paid |
No tool is perfect – sarcasm and contextual language can deceive AI. The best approach combines a mix of AI speed with human judgment.
Facebook sentiment analysis example [5 steps]
Now that you know the two methods of analyzing Facebook sentiment, you can decide which suits you best. If the manual method works for you, there’s no need to continue reading this article.
But if you’re curious about how to analyze Facebook sentiment using a sentiment analysis tool, sit back and relax. I’ll guide you through the step-by-step process using Brand24 as an example.
Brand24 is an AI-powered social listening tool designed to track and analyze your sentiment and, more broadly, monitor your brand’s reputation.
In addition to Facebook, Brand24 can perform sentiment analysis across various sources (or combine them for a complete overview):
- Social media platforms like Instagram, TikTok, YouTube, TikTok, X (Twitter), LinkedIn, Telegram, Reddit, and Twitch;
- News sites, blogs, video platforms, podcasts, review sites, newsletters, and other websites.
Are you ready to dive in? Great, let’s take the first step!
Step 1: Set up the monitoring project and collect data
Create a monitoring project in Brand24 by entering the keyword you want to track. This can be your brand name, a competitor, a hashtag, a campaign name, or any term relevant to your analysis.
Then let the tool collect mentions. Depending on your brand’s volume, you’ll start seeing data within minutes.
That’s an excellent time to brew coffee.
Once mentions are ready, apply the Facebook filter in the Sources panel to focus exclusively on Facebook data. You can also filter by sentiment, language, geolocation, and more.
Step 2: Check the sentiment breakdown
Okay, let’s dive into Facebook sentiment insights!
In the Mentions tab, switch the chart view to Sentiment. You’ll see green (positive) and red (negative) trend lines. They give you an instant visualisation of how sentiment is trending.
For a precise breakdown, go to the Analysis tab. Here’s what Red Bull’s data showed over 30 days:
As you can see, over the past 30 days, Red Bull was mentioned 1,867 times on Facebook, with 477 positive mentions and just 44 negative feedback mentions.
The takeaway? Red Bull enjoys overwhelmingly positive sentiment on Facebook, with only 2% negative mentions.
Step 3: Dive into topics
If you’re the type of person who loves a data-driven approach, I have great news! There’s even more you can uncover from Brand24’s sentiment analysis on Facebook.
The AI Topic Analysis identifies which themes or subjects are most frequently associated with your brand in Facebook conversations.
For each topic, you’ll see the number of mentions, reach, share of voice, and sentiment breakdown. All these data help you understand which themes drive positive or negative perception.
In Red Bull case, sponsored events, sport teams, and user-generated content drive the most interest—especially in volume.
Actionable insight: Use topic data to guide your content strategy. If certain themes consistently drive positive sentiment, lean into them in future campaigns.
Step 4: Detect influencers
Like other largest social media networks, Facebook is home to its own influencers.
Brand24 helps you identify these influential profiles and analyze their impact on your brand awareness, visibility, and reputation.
Simply, you can see who drives the most engagement, starts discussions, and extends your reach.
This feature allows you to determine the best candidates for collaborations or partnerships, helping you connect with a broader audience beyond your current customers.
With these insights, you can build meaningful relationships with the right people to maximize your brand visibility on Facebook.
Step 5: Track the sentiment over time
You should treat sentiment analysis not as a one-time thing but as a continuous process of tracking and evaluating your communications strategy.
In other words, you should make doing your sentiment analysis a habit.
It’s important because even one negative comment (i.e., from an influencer) can harm your brand reputation on Facebook. Therefore, always keep your finger on the pulse.
To track and understand your Facebook performance, use Brand24’s “Compare periods” feature. It shows how your sentiment evolves week over week or month over month.
As you can see, Red Bull is doing really well in terms of consistency. Although the number of Facebook mentions dropped, the reach went up. It means that the quality of mentions even improved!
Keep going, guys!
