Paid advertising no longer lives in isolation from how patients actually search. More patients now begin their provider research inside AI assistants, asking ChatGPT, Google Gemini, Perplexity, Microsoft Copilot, and Claude for recommendations before they ever click an ad.
That shift changes what your paid metrics mean. Branded search demand created by AI-driven discovery influences your CTR and CPC, and the structured, authoritative content that earns AI citations also strengthens the landing pages your ads point to, improving conversion rate, cost per lead, and ROAS at the same time.
