Indexation Monitor

Sample-based URL inspection per pillar via gsc-mcp.inspect_url. Cheap, focused tool — does ONE thing well.

When to Use

• Stage 1 Discovery weekly — surfaces indexation lag as opportunity context.
• Stage 8 UX per-ship — verify shipped pages get indexed.
• Per-pillar launch (Monday rhythm in 030-launch-cadence.mdc) — verify launch took effect.
• Ad-hoc: incident response.

Do Not Use When

• Need full SEO health audit — use seo-health.
• Need traffic snapshot — use traffic-monitor.

Inputs

• Pillar list from nextjs-app/src/shared/launch/pillars.ts
• URL sample per pillar (default 20 URLs sampled deterministically per pillar via hash)
• gsc-mcp.inspect_url (1 quota per call, cached 30d)

Workflow

Weekly run

1. For each launched pillar:
   • Sample 20 URLs deterministically (hash-based for cache stability).
   • Call gsc-mcp.inspect_url per URL (skips on cache hit).
   • Compute indexation rate = indexed_count / sample_count.
2. Per launched pillar:
   • Check indexation rate against SLO (≥90% within 30d post-launchedAt).
   • Flag pillars stuck below 80% at 14d post-launch.
   • Trigger S2 if any pillar drops <70%.
3. For pSEO templates with launched URLs:
   • Per-template sample of 20 URLs.
   • Compute per-template indexation rate.
   • Flag templates <70% indexed at 60d post-launch (Schwartz framework).

Per-pillar launch (Monday)

• Run immediately after Vercel deploy completes.
• Verify pillar URLs are still being served (no noindex accident).
• 24h post-launch: re-sample to verify indexation has started.

## Indexation Monitor — <date>

### Per-Launched-Pillar Indexation
| Pillar | Days post-launch | Sample size | Indexed | Rate | Status |
|---|---|---|---|---|---|
| foundation | 60d | 20 | 19 | 95% | PASS |
| tools | 25d | 20 | 18 | 90% | PASS |
| editorialGuides | 18d | 20 | 14 | 70% | WARN — below 80% at 14d |
| ... | ... | ... | ... | ... | ... |

### Per-pSEO-Template Indexation
| Template | URLs sampled | Indexed | Rate | Status |
|---|---|---|---|---|
| city-role-page | 20 | 14 | 70% | PASS (≥70%) |
| state paycheck calculator | 20 | 19 | 95% | PASS |
| ... | ... | ... | ... | ... |

### Flagged
- editorialGuides: 70% at 14d (target ≥80%) → schedule for Discovery as `link_injection` candidate
- (none): no S1/S2 conditions

### Quota Used Today
- gsc-mcp.inspect_url calls: <count> / 2000 daily quota

Incident Triggers

Per seo-foundations/reference/excellence-targets.md Standard A:

• Launched pillar indexation drops <50% = S2 → indexation-regression.md runbook.
• Launched pillar noindex accident detected = S1 → noindex-accident.md runbook.
• Sitemap omission of launched URLs = S1 → sitemap-drift.md runbook.
• pSEO template indexation <50% = S2 → pseo-thinning.md runbook.

Sampling Discipline

• Deterministic hash-based sampling so the same URLs are inspected over time (allows trend tracking).
• Default sample 20 URLs per pillar; raise only when investigating a flagged regression.
• Cached 30d per 040-mcp-usage.mdc; only re-inspects when window expires.
