Top 3 issues

1. Main content is invisible to AI crawlers. Server-side render or statically generate the page so the main content ships in the initial HTML.
2. Structured data is injected client-side only. Your JSON-LD appears only after JavaScript runs, so AI crawlers never see it. Emit it in the initial HTML.
3. No meta description in the initial HTML. Add a server-rendered meta description.
