## HTTP Link Headers & HTML Signals (AI-Optimised Discovery)

Every content page emits `Link:` HTTP headers for fastest structured-data discovery by AI crawlers (no HTML parsing needed — a HEAD request suffices):
- `/compare/{slug}` → Link: <api/v1/schema/{slug}>; rel="describedby"; type="application/ld+json"
- `/blog/{slug}` → Link: <api/blog/{slug}>; rel="describedby"; type="application/ld+json"
- `/entity/{slug}` → Link: <api/v1/entities/{slug}>; rel="describedby"; type="application/json"
- `/category/{slug}` → Link: <api/v1/comparisons?category={slug}>; rel="describedby"; type="application/json"
- `/alternatives/{slug}` → Link: <api/v1/alternatives/{slug}>; rel="describedby"; type="application/json"
- `/best/{slug}` → Link: <api/v1/best/{slug}>; rel="describedby"; type="application/json"
- `/hub/{slug}` → Link: <api/v1/hub/{slug}>; rel="describedby"; type="application/json"
Content negotiation: GET /compare/{slug} with Accept: application/ld+json → 303 redirect to api/v1/schema/{slug}

HTML pages also emit inline signals for parsers that skip HTTP headers:
- `<link rel="cite-as" href="{canonical}">` — W3C preferred citation URL
- `<link rel="license" href="https://creativecommons.org/licenses/by/4.0/">` — CC BY 4.0
- `<meta http-equiv="content-language" content="en">` — explicit language declaration
- `<link rel="describedby" type="application/ld+json" href="{api-url}">` — machine-readable description

## GEO Signals (AI Crawler Freshness & Visual Context)

All JSON-LD API endpoints emit a consistent set of signals for AI temporal and visual grounding:
- `inLanguage: "en-US"` — ISO locale on every JSON-LD node across all content API endpoints
- `image.contentUrl` — machine-readable OG image URL (1200×630 PNG) on Article, BlogPosting, and ClaimReview nodes
- `thumbnailUrl` — direct OG image URL for AI visual crawlers on comparison Article, BlogPosting, and schema API Article nodes
- `contentReferenceTime` — ISO 8601 "data as of" timestamp on comparison Article and BlogPosting schemas; tells LLMs the freshness window for time-qualified answers
- Sitemap shards 1–4 (`/sitemap/1.xml`–`/sitemap/4.xml`) include `<image:image>` entries for every comparison, entity, alternatives, blog, and review URL — Google Images + AI visual crawlers get primary images without a separate image sitemap fetch
- `ClaimReview.inLanguage: "en-US"` and `ClaimReview.itemReviewed.inLanguage: "en-US"` on `/api/answer/{slug}` — enables language-scoped AI fact-checking
- `/api/answer/{slug}` GET response now emits `Link:` header pointing to canonical, knowledge-graph, FAQ, and OpenAPI URLs — mirrors the HEAD response for crawlers that issue full GETs
- `SoftwareApplication.featureList` — derived from per-entity comparison attribute values (text, number+unit, boolean-true); enables Google Shopping and Perplexity product-mode carousels to surface per-entity capabilities
- `SoftwareApplication.applicationSubCategory` — mapped from comparison category (14-category lookup: technology→DeveloperApplication, health→HealthApplication, sports→SportsApplication, finance→FinanceApplication, gaming→GameApplication, travel→TravelApplication, entertainment→EntertainmentApplication, companies→BusinessApplication, automotive→UtilitiesApplication)
- `genre` on Article nodes in `/api/knowledge-graph/{slug}` and `/api/v1/schema/{slug}` — derived from comparison category; AI indexers and Google Discover carousels use genre for topic routing
- `potentialAction: [ReadAction, CompareAction]` on knowledge-graph and v1/schema Article nodes — CompareAction includes typed competitor object[] so AI routers can match "X vs Y" queries to the correct comparison page
- `SportsEvent` node in `/api/knowledge-graph/{slug}` for sports-category comparisons — competitor[] typed to SportsTeam/Person; enables Google Sports and Perplexity sports-mode carousels
- Entity nodes in `/api/v1/schema/{slug}` upgraded from generic `Thing` to fully-typed entities (SoftwareApplication, Person, Country, SportsTeam, etc.) with `inLanguage: "en-US"`, `image.contentUrl`, and `subjectOf` back-reference to Article node
- Entity API (`/api/v1/entities/{slug}`) default JSON response now emits `Link:` header (canonical, LD+JSON alternate, alternatives, service-doc) — matches LD+JSON content-negotiation path already in place
- Entity nodes in `/api/knowledge-graph/{slug}` upgraded from generic `Thing` to fully-typed entities (entitySchemaType mapping) with `inLanguage: "en-US"`, `image.contentUrl` ImageObject, `sameAs` Wikipedia, and `subjectOf` back-reference to Article node — mirrors `/api/v1/schema/{slug}` typing depth
- `significantLink` on `/api/knowledge-graph/{slug}` Article extended to include `/api/answer/{slug}` + `/api/v1/schema/{slug}` — AI graph traversal now reaches all machine-readable representations from a single Article node
- `significantLink` added to `/api/v1/schema/{slug}` Article node — entity profiles, alternatives, answer API, and knowledge-graph URL — matching knowledge-graph endpoint coverage
- Dataset `distribution` in `/api/v1/schema/{slug}` expanded from single entry to full 6-item array (schema JSON-LD, knowledge-graph, raw comparison JSON, answer API, FAQ JSON, related comparisons) — mirrors knowledge-graph Dataset distribution depth
- `citation` field on comparison Article nodes upgraded: now always populated — explicit `citationStats.sources` merged with per-entity Wikipedia `CreativeWork` references; applies to 2-entity schema path, multi-entity schema path, `/api/knowledge-graph/{slug}` Article, and `/api/v1/schema/{slug}` Article — every comparison Article now provides AI fact-checkers a citation chain
- `relatedLink` added to comparison Article nodes in all 4 schema paths (2-entity, multi-entity, knowledge-graph API, schema API) — up to 8 related comparison URLs; AI crawlers use `relatedLink` to traverse topic clusters and surface related comparisons in carousels
- Dataset `variableMeasured` upgraded from bare attribute name strings to `PropertyValue` objects with `name`, `unitText` (when available), and `description` (when available) — Google Dataset Search and AI research tools extract structured attribute metadata from typed `PropertyValue` nodes
- `isAccessibleForFree: true`, `conditionsOfAccess: "Free"`, `dateModified`, `author`, `publisher`, `isPartOf` added to FAQPage nodes in `/api/knowledge-graph/{slug}` and `/api/v1/schema/{slug}` — Google FAQ rich results + AI answer-engine citation eligibility requires these fields
- `Answer.inLanguage: "en-US"` added inside FAQPage `acceptedAnswer` nodes in both knowledge-graph and schema routes — language-scoped answer extraction for multilingual AI engines
- Organization schema `abstract` field added — AI KG citation engines (Perplexity, ChatGPT) prefer `abstract` over `description` for entity summaries; distinct from search-snippet-oriented `description`
- Country entity nodes in `buildMultiEntityGraph` + `buildTwoEntityGraph` schema paths gain `geo: { "@type": "GeoShape", name }` — signals geo-typed entity to Google Geo crawlers and Perplexity/ChatGPT country-query routing; `containedInPlace` upgraded from bare `"Earth"` Place to `{ name: "World", sameAs: "https://en.wikipedia.org/wiki/World" }`
- WebPage node in `/api/v1/schema/{slug}` gains `primaryImageOfPage: ImageObject` (OG image, 1200×630, `@id: #primaryImage`) so Google and AI crawlers use the comparison card image as the canonical visual; also adds `isAccessibleForFree: true` + `conditionsOfAccess: "Free"` on WebPage
- DataCatalog schema gains `abstract` (AI KG citation summary), `potentialAction: SearchAction` pointing to `/api/v1/search`, and `dateModified` upgraded from YYYY-MM-DD to full ISO 8601 datetime
- Dataset node inside DataCatalog and WebApplication schema `dateModified` fields upgraded from `.slice(0,10)` truncation to full ISO 8601 — 3 truncation sites fixed in schema.ts
