Demand Capture is the work of converting existing buyer intent when people are already searching, comparing, asking, or ready to take action.
It matters because strategy keeps channels from competing with each other. When this concept is clearly defined, the team can connect budget, audience, creative, offer, tracking, and reporting to revenue instead of chasing disconnected metrics.
Example
Someone searches for a provider who can perform a specific service in their city. A relevant search listing or ad and a clear service page can help the business respond to that existing intent.
