Influencer marketing is one of the strongest approaches a brand can use to communicate with the audience. While traditional metrics can tell us a lot, they are not the whole picture. Sentiment analysis shows the true feelings of target audiences toward the brand’s campaigns and products.
Brands use advertising to communicate with their target audience, and influences are the messengers that carry brand ideas forward. Within this flow, brands naturally need some kind of feedback to know if the message has hit the target. Of course, we have metrics, engagement rates, and sales numbers — the solid figures. But what about emotions? While the numbers are very useful, they do not paint the full picture of an ad campaign.
That is why brands need sentiment analysis. It’s a marketing tool that helps brands look into the hearts of their followers. Using sentiment analysis can give you information about the reception of your brand’s partnerships with influencers on a more emotional level.
Sentiment analysis (sometimes referred to as opinion mining or social listening) is not a groundbreaking idea as of 2024; it has been around since at least 2003, while the studies that linked marketing strategies and public opinion are even older. The underlying idea is simple: emotional responses to advertising are faster and stronger than rational ones, so measuring this sentiment is crucial to assessing the campaign’s success. With influencer marketing, in particular, emotions run the show.
This analysis covers reviews, social media posts, and surveys to gauge the audience’s sentiment on a spectrum: positive, negative, or neutral. The newer tools driven by machine learning make it possible to understand more shades of meaning in the audience's feedback and make more informed decisions.
Sentiment analysis is important for brands because basic metrics such as audience reach, sales, views, and likes are not enough to understand the true impact of their content and products.
So, how exactly can brands benefit from sentiment analysis?
Of course, this is not an exhaustive list, but the main application areas of sentiment analysis already show it to be a powerful tool for brands.
Understanding how to interpret sentiment data is crucial for making informed marketing decisions. Depending on the type of data you collect, there are different methods of calculating sentiment scores. This is a short version of two approaches from SproutSocial, one of the tools we mentioned earlier.
Method #1: A total of positive words versus negative words in a given text. This method is often used for long-format content, such as big product reviews.
Formula: # negative words – # positive words divided by the number of words = sentiment score
In this example, marketers used a code to calculate the total number of words in each user review, and then assigned positive and negative labels to the words based on an existing list known as the Opinion Lexicon. Knowing these three values (positive words, negative words, and total number of words), marketers calculated the sentiment score for every user review following Formula #1.
Method #2: Ratio of positive and negative word counts
Formula: # positive words / # negative words + 1 = sentiment score
This method is preferable for scoring big data because it includes both positive and negative words. This way, the longer reviews do not affect the score too much, and the average result is more manageable. In this system, a score of 0 is exactly in the middle, or neutral. A higher score is related to positive, and a lower score is related to negative.
In 2016, rental provider Airbnb used sentiment analysis to gauge public opinion and stem the public backlash after being accused of discrimination.

The brand launched its “We Accept” campaign, which not only helped repair Airbnb's reputation, but also contributed to real anti-discrimination efforts across the globe.
A case of not applying enough sentiment analysis while choosing the influencer and the tone of voice is the controversial Peloton Christmas ad that has been labeled sexist and caused a lot of resentment among the company’s audience.

Sentiment analysis could have helped the brand identify the potential for negative perceptions and adjust the ad or select a different influencer better aligned with their brand values.
In 2019, Nike monitored real-time reactions across social media to identify which messages and athletes generated the most positive sentiment toward the company. The “Dream Crazier” campaign featured female athletes and was narrated by Serena Williams, the main idea being challenging gender stereotypes in sports. 
Sentiment analysis enabled agile campaign management and helped Nike navigate potential controversy.
