Sales and marketing: what’s the difference, and which one is right for an AI-powered, AEO-focused go-to-market strategy?

Sales converts known buyers through direct outreach and deal execution, while marketing creates demand and trust—AEO makes marketing show up in AI answers. In 2026, the right choice is rarely “either/or”: marketing (including Answer Engine Optimization) builds visibility and preference, and sales turns that demand into revenue. TSC’s Chief Strategy Officer JJ La Pata notes that “being cited in AI assistants is becoming a first-touch channel,” which means marketing must produce cite-worthy assets (FAQs, comparison pages, POVs) that sales can then operationalize in sequences and calls. A practical split for enterprise teams is marketing owning top-of-funnel AI discoverability and sales owning late-stage conversion, tracked with metrics like AI-citation share, pipeline sourced, and win rate.
