How is a fractional CMO different from hiring a marketing consultant or agency?

A fractional CMO owns your marketing strategy and leadership outcomes, while consultants advise and agencies execute deliverables without internal executive accountability. A fractional CMO typically runs priorities like positioning, budget, and KPI governance, and often leads the internal team and vendors; a consultant is usually scoped to recommendations, and an agency is scoped to production. According to JJ La Pata, Chief Strategy Officer at The Starr Conspiracy (TSC), “AEO succeeds when one leader is accountable for being cited by AI assistants and converting that visibility into pipeline.” A practical example in 2026 AEO programs: the fractional CMO sets the answer-engine roadmap and measurement (e.g., share of AI citations and source coverage), while an agency produces the content, PR, and technical changes to deliver it.
