"potentialAction": {
  "@type": "ReserveAction",
  "target": "https://yoursite.com/book"
}

]

No Google Maps or Business Profile presence detected — AI agents may not verify your location

No review/rating schema — agents can't surface your reputation

Partial security headers (CSP only)

No dateModified/datePublished in schema — agents can't judge freshness
