Overview
Which reason to buy do people search for, and which is growing? Use when the user is choosing a positioning, a message or a campaign angle and asks which benefit or reason to buy matters most to buyers, or which is gaining. US Google searches for each buying angle in a category ("healthy protein snacks"), their shares and growth beyond an everyday control basket. If its pre-declared control fails, the run refuses and nothing is charged. Pay per run with x402 (USDC on Base) or MPP.
