What it means
The same figure can mean
strength or dependence
When buyers search for your name, they already know you. Their searches show how well known you are among the people you have already reached. Category searches describe what you sell without naming you, so they show buyers who do not know you yet.
Brand Demand Capture compares the two. If it is high, nearly all the demand you capture comes from buyers who already know you. If it is low, few buyers search for your name, and your demand depends on category searches.
Read the figure with the other two findings. If leakage and untapped potential are low, a high figure means your name brings the buyers and little remains to win. If they are high, your name brings buyers, yet much of your visibility still leaks to competitors and your category visibility holds room for growth.
The difference matters commercially. A business that wins only the buyers who already know it grows through relationships and referrals. A business that wins category searches grows through the market itself.
Two terms to keep apart
Brand awareness is what buyers tell a survey they know about you. Brand Demand Capture is what buyers did when they searched. A business can be well known in surveys and still win few category searches. The scan measures the searches.
Marketing teams also use "demand capture" for a tactic: reaching buyers who already want to buy, through paid search and outbound sales. Here the term means something else: the demand your business already captures, and where it comes from.
