Key Findings
1. SEO ≠ AEO
Average scores across the 18 successfully scanned brands: SEO 67 (C) vs AEO 40 (E). A 27-point gap. Taiwan enterprises have invested in traditional SEO but almost zero AEO optimization.
2. Same industry, massive gap
E.SUN Bank: AVS 69. Cathay Bank: AVS 36. Same industry, 33-point difference. When someone asks ChatGPT "recommend a bank in Taiwan," AI will favor E.SUN, not because of service quality, but because of website AI-friendliness.
3. Zero llms.txt adoption
None of the 18 successfully scanned enterprises had a llms.txt file. This is the emerging standard for AI-readable site context. Zero cost to implement, but nobody has done it.

FAQ
How visible are Taiwan enterprise websites in AI search?
Not very. This report scanned 25 well-known Taiwan enterprise websites with UltraProbe, 18 of which were scanned successfully, and none scored A-grade or B-grade. The highest was E.SUN Bank at 69 (C-grade), the lowest was United Daily News at 26 (F-grade), and average AEO was only 40/100 (E-grade).
If my SEO is good, will my AEO be good too?
No. The scanned enterprises averaged 67 (C-grade) on SEO but only 40 (E-grade) on AEO, a 27-point gap: most have done basic SEO but almost no AEO for AI search. Even the website of AI company Appier scored 85 on SEO and only 50 on AEO.
What is llms.txt, and do Taiwan enterprises use it?
llms.txt is an emerging standard that helps AI crawlers understand your website, and it costs nothing to set up. None of the 18 Taiwan enterprises this report scanned successfully had a llms.txt file.
