Sounder’s IAB Category Sentiment helps publishers move beyond understanding what their content is about, and into how it is being discussed. This additional layer of insight brings emotional context into Audio Insights, creating a more complete view of content suitability and commercial value.

Within Audio Insights, publishers can see how IAB categories are discussed across their episodes, whether the tone is positive, negative, neutral, or mixed. This enables a more nuanced understanding of content that goes beyond traditional classification.

More importantly, publishers can activate this insight through Contextual Tags that incorporate sentiment. This allows them to package inventory in a more precise and commercially relevant way, aligning directly with advertiser expectations and potentially unlocking higher CPM opportunities.

Adding emotional context to IAB categories
IAB Category Sentiment enhances contextual classification by assigning sentiment to each detected IAB category within audio content.

Each category is labelled as:
• Positive
• Negative
• Neutral
• Mixed

This allows publishers and advertisers to move beyond topic identification and gain a more complete understanding of content across both segment and episode levels.

Why sentiment matters in audio intelligence
In audio, context is everything. A category like “travel” can represent inspiration, disruption, frustration, or simple information depending on how it is discussed. Each of these carries different value depending on advertiser goals.

With sentiment applied, publishers gain a clearer view of how their content is framed, not just what it is about. Advertisers, in turn, benefit from better alignment with environments that reflect their brand and campaign objectives.

For example:

• Travel brands can prioritize positive travel content
• Travel insurance advertisers may prefer content that reflects challenges or negative travel experiences
• Education advertisers can focus on positive adult learning discussions

Turning insight into activation with Contextual Tags
One of the most powerful applications of sentiment is its role in building Contextual Tags within Audio Insights.

By combining IAB categories with sentiment, publishers can create more precise and commercially relevant targeting segments.

Examples include:
• Travel - Negative for travel insurance campaigns
• Adult Education - Positive for education-focused advertisers

This level of precision enables stronger contextual alignment and can support higher value inventory opportunities through improved relevance.

How sentiment is applied across content
Sentiment is applied at both the segment and episode level.

Each segment is analyzed and assigned a sentiment per IAB category. These signals are then aggregated to generate an episode-level view. While segments may contain different tones for the same category, the final episode-level sentiment reflects the overall distribution of signals.

Publishers can view sentiment in My Episodes under the Contextual view, with additional breakdowns available in the episode sidebar.

From insight to activation
By combining contextual classification with sentiment, Audio Insights provides a more complete and actionable view of audio content.

Publishers can better understand their inventory, refine segmentation strategies, and create more valuable contextual packaging. Advertisers benefit from improved alignment, reduced brand risk, and more relevant placements across premium audio environments.
