Top 3 issues

Server-level blocking of AI crawler user agents. Requests with AI crawler user agents get blocked at the edge. Review CDN/WAF bot rules if you want AI visibility.
Page does not have exactly one H1. Use a single H1 stating what the page is about.
No llms.txt. Informational only. Independent 2026 data (Ahrefs, SE Ranking, Google documentation) shows no measurable citation effect from llms.txt. It is checked because it costs nothing and some assistants read it, but it moves neither crawling nor ranking.
