## How to Improve AI Discoverability

1. Add llms.txt file at the root to provide ​structured brand and product information for AI crawlers (currently absent), ‍improving AI citation accuracy.
2. Implement FAQ Schema (JSON-LD) on the FAQ page — currently no FAQ schema detected, which means ‌AI engines cannot extract Q&A pairs for featured snippets or ‌AI answers.
3. Add Organization and Product structured data (JSON-LD) with ‍full address, telephone, and founding date to improve local and ​entity recognition by AI search engines.
4. Create dedicated product spec pages with technical data tables (bore size, gripping force, RPM, ‌material) — AI assistants need specific numeric data to recommend ‍products in response to technical queries.
5. Add a dedicated 'Why AUTO STRONG / About' landing section with the Taiwan Excellence Award, 50-year history timeline, and export market data — storytelling ‌content is heavily favored for AI-generated brand summaries and citations.
