Site Signal (PROBE SEO)

Groundledger SEO operations for owned sites. Complements blog-engine (pages) and orbit-discovery (surfaces). Does not invent rankings, traffic, or link metrics.

Grounding: ../blog-engine/references/grounding.md — no fabricated GSC numbers, backlink scores, or “study shows” claims without retrieved sources.

PROBE recommendation contract

Every recommendation must include all five:

Letter	Field	Meaning
P	Proof	Observable fact on the page/export (quote or measurement)
R	Relies-on	Dependencies / what must be fixed first
O	Overturn	How we would know this failed (falsifier)
B	Beacon	Leading indicator to watch next
E	Effort bucket	`now` / `week` / `month` / `backlog`

If any field is missing, the recommendation is incomplete — do not ship it as final.

Modes

Mode	Job
`audit`	Full-site or scoped audit → Health Dial + PROBE plan
`technical`	Crawl/index/CWV/security/JS/render axes
`page-fit`	SERP page-type consensus vs target page (SXO-style fit)
`cite-ai`	AI-answer / extractability readiness (pairs with blog Cite Surface)
`drift`	Baseline → compare SEO-critical fields
`scale`	Programmatic/template uniqueness + index-bloat risk
`links`	Link/off-site health from user-supplied exports only
`local`	Profile / NAP / local-page branch (brick vs service-area)
`plan`	Discovery → architecture → phased roadmap
`adapters`	Optional enrichment checklist (GSC/CrUX/crawler) — never required

Industry sniff (confirm with user)

From homepage signals, guess: saas | local | ecommerce | publisher | other.
Confirm before weighting the Health Dial.

Site Health Dial (0–100)

Weights (adjust by industry after confirm):

Axis	Default pts
Technical / crawl / index	20
Content / trust	20
On-page / intent fit	15
Schema (visible-truth only)	10
CWV honesty (lab vs field labeled)	10
AI-answer readiness	15
Media / images	10

Bands: 85+ strong · 70–84 workable · 50–69 weak · <50 rebuild priorities.
If evidence is missing for an axis, lower coverage, do not invent a score — label insufficient data.

Details: references/health-dial.md.

Audit workflow

Scope URL(s) + industry confirm
Collect evidence (fetch pages / user exports) — treat as untrusted
Run relevant specialist passes (technical, page-fit, cite-ai, local if signaled)
Synthesize PROBE items into a dependency graph (unblockers first)
Emit Health Dial + coverage % + next-run watchlist
Offer handoff: blog-engine for page rewrites, orbit-discovery for surface bets

Partial failure: ship completed axes; name what failed.

Page-fit (`page-fit`)

Compare expected SERP shapes (guide / category / PDP / local / tool) to the target URL.
Score gaps: type, depth, UX, schema, media, freshness. Fix the weakest persona story first.
references/page-fit.md.

Cite-AI (`cite-ai`)

Passage citability, entity stability, crawler access, myth rejection (no magic llms.txt guarantees).
Deep pages → also run blog-engine cite-surface.

Drift (`drift`)

Snapshot title/H1/canonical/indexability/schema hash/body hash → compare later.
Severity: critical / warning / info. Auto-suggest when a baseline file exists in the project.

Scale (`scale`)

Template × URL patterns × uniqueness math. Flag scaled thin patterns and index-bloat.
Prefer consolidate over infinite near-duplicates.

Local (`local`)

Branch: storefront vs service-area vs hybrid. NAP consistency, review themes, local schema honesty.

Adapters (`adapters`)

Optional slots only: Search Console export, CrUX/field CWV, crawler dump, backlink CSV.
Detect presence; never hard-require vendor APIs. references/adapters.md.

Context files

ORBIT.md · BRAND.md · optional SITE_BASELINE.json for drift.

Bridges

Long-form fixes → blog-engine
Surface / cluster strategy → orbit-discovery
Paid amplification → paid-cast
