Definition

A comment signal is the engagement and content generated in the comments section of a social media post — including questions, answers, additional information, and user reactions. AI systems indexing social platforms increasingly treat comment content as part of the overall document signal for a piece of content. Comments extend the informational surface area of a social post. A video that answers a question in its content, and whose comment section contains additional specific answers, use cases, and named entities, creates a richer retrieval document than the video alone. For brands managing social content, treating the comment section as a content layer — answering questions thoroughly, adding context, naming relevant entities — extends the AI citability of each post beyond its original transcript.
