Traffic Diversification: Companies must optimize for:
- Direct brand traffic

- Traditional web traffic (declining but still relevant)
Content Evolution: LLMs prioritize:
- Conversational language over static content
- Agent-friendly structures (lists, definitions)

"With LLMs increasingly cutting brands out of early buying stages, traditional SEO is no longer enough." - Bain & Company

Sectors seeing fastest adoption include retail shopping, learning platforms, and styling services, where consumers are comfortable sharing data for personalized recommendations. Bain emphasizes that companies failing to adapt risk losing customers without even realizing it, as purchase journeys increasingly happen entirely within AI interfaces.
