A higher net sentiment means there are more positive than negative mentions, and a lower net sentiment means the opposite. Comparing the net sentiment across periods can help show whether your keywords are improving or worsening.

The metric is determined by weighing the number of positive and negative mentions.
If you have 40 mentions where 35% are positive, 59% are neutral, and 6% are negative your net sentiment is +29% (35-6 = 29).
