2. Marketing Practice Guide
① AEO, First-Party Data, and AI Ops: Preparing for 2026 Structural Competition
According to BAT Insights, digital marketing in 2026 is defined as a "competition of structures, not campaigns." Practitioners are advised to focus on seven key changes: AEO (Answer Engine Optimization), short-form commerce, first-party data, and AI operations.
- AEO Transition: Beyond traditional SEO, the goal is to structure content so that brands frequently appear in AI answer engines.
- Internalizing First-Party Data: Building internal data collection and analysis systems is essential following the phase-out of third-party cookies.
- Integrating AI Operations: As AI becomes integrated into daily workflows, teams must redesign work processes rather than just using AI as a simple tool.
② Brand Exposure in the Age of AI Search: Mastering Initial Prompts
Ascent Korea’s 2026 marketing trend analysis notes that as AI aggregates reports, case studies, technical docs, community opinions, and competitor comparisons to generate answers, the marketer's objective must shift.
"The task for 2026 is not just to increase website traffic, but to design content so that your brand consistently appears in answers to queries reflecting relevant consumer contexts and situations."
In short, the core strategy is to design data assets and content so that the brand repeatedly surfaces within AI responses.
③ Advertising Strategy in the Age of Agentic Commerce: Strengthening Unaided Awareness
Motive Intelligence released a report on branding strategies for the era of "Agentic Commerce" (shopping based on AI agents), emphasizing the importance of Unaided Awareness.
