Not getting the results you used to from your paid search? In this episode of the DMI podcast, host Will Francis speaks with PPC specialist Cathal Melinn about the current state and future of pay-per-click advertising. With rising costs, AI-driven automation, and new campaign types like Demand Gen reshaping advertising, Cathal shares what’s actually delivering results right now, and what marketers should approach with caution.
They explore why PPC is still profitable (but less forgiving than before), how AI Max for Search differs from Performance Max, and why mid-funnel campaigns are becoming essential. Cathal also explains how to structure campaigns strategically, manage budgets effectively, and avoid over-relying on automation.
