💡 The Shift: From SEO to AEO (Agent Engine Optimization)

For 20 years, travel discovery was SEO: spending billions on Google Ads to fight Booking.com and Airbnb for search keywords.

Today, high-net-worth travelers don't open 40 browser tabs. They ask Claude, ChatGPT, and Gemini:

"Plan a 7-day luxury stay in Greece for 6 adults in July with an infinity pool, sea view, and a 50ft catamaran charter for 2 days under €700/night."

AI assistants don't display banner ads. They check their connected MCP tools, query real-time PMS inventory, present verified direct-owner listings, and lock the dates with zero OTA middleman markups.

SEO was "rank where people search." TravelOS is "get installed where travelers ask."
