[Generated JSON-LD: All Recommended Schemas](#10-generated-json-ld-all-recommended-schemas) 11. [Implementation Checklist](#11-implementation-checklist) --- ## 1. Executive Summary The page currently implements **three** JSON-LD schema blocks: Service, BreadcrumbList, and FAQPage. All three use correct `@context` ("https://schema.org") and valid JSON-LD syntax. However, the audit uncovered the following issues: | Severity | Issue | Impact | |----------|-------|--------| | **CRITICAL** | Duplicate BreadcrumbList rendered in HTML | Google may flag conflicting data or ignore both | | **HIGH** | FAQPage schema on a non-government, non-healthcare site | Restricted since August 2023; will NOT generate FAQ rich results | | **MEDIUM** | Service schema missing several recommended properties | Reduced eligibility for rich results | | **MEDIUM** | No WebPage schema | Missing core page identity signal | | **MEDIUM** | No Organization schema on this page | Weak entity association for Knowledge Graph | | **LOW** | No SoftwareApplication schema for the product | Missed opportunity for product-level signals | | **LOW** | Offer missing `price` or `priceSpecification` | Offer block is structurally incomplete | **Overall grade: C+** -- The foundation is solid but there are compliance issues, a rendering bug, and significant missed opportunities. --- ## 2.
