/navboost-audit — Engagement signal audit

Target: $ARGUMENTS

Background, click typology, and baselines: ${CLAUDE_PLUGIN_ROOT}/skills/seo-fundamentals/references/navboost.md. Scorecard bands: ${CLAUDE_PLUGIN_ROOT}/skills/seo-fundamentals/references/scoring-spec.md.

Inputs

Domain; brand name(s) and variants; primary topic cluster(s). Data: Google Search Console and GA4 — via MCP if connected, otherwise ask for CSV exports or screenshots (GSC: queries and pages, 12 months; GA4: landing pages with sessions, engaged sessions, average engagement time). Modules without data are skipped and listed as "not run", never estimated.

Modules (10 points each)

1. Position-normalized CTR — top 100 queries by impressions: actual CTR ÷ expected CTR for the position (baselines in navboost.md; adjust for SERP features). ≥1.2 STRONG · 0.8–1.2 AT BENCHMARK · <0.8 WEAK. Site score from the share of queries ≥1.0 (target ≥40% above benchmark). Flag queries where an AI Overview appeared before calling a CTR drop "weak copy".
2. Pogo-stick proxy — top 20 organic landing pages: share of sessions <10 s with no interaction. <20% STRONG · 20–40% WATCH · >40% WEAK.
3. Engaged sessions ratio — site-wide >60%, per page >50%.
4. Session duration — top 20 landing pages, median engagement time; bounce-back-to-organic rate as a lastLongestClick failure proxy.
5. Branded search volume — 12-month trend (GSC brand filter + Trends): growing / flat / declining.
6. Brand + topic queries — GSC filter brand AND topic: the best available topical-authority proxy; growing / stable / declining.
7. Knowledge Panel — present? complete (logo, description, sameAs-backed profiles, related topics)?

Output

1. Scorecard: 7 modules × 10 = 70, with "not run" modules excluded from the total and the denominator shown.
2. Verdict: STRONG 56–70 · GOOD 42–55 · WATCH 28–41 · WEAK 14–27 · CRITICAL 0–13 (pro-rate when modules are missing).
3. Top-3 weak queries (meta rewrite candidates → /meta-tags).
4. Top-3 weak landing pages (content-intent mismatch → /optimize).
5. Branded and brand+topic trend summary (chart if data allows).
6. Knowledge Panel gap report (→ Organization schema with sameAs, /schema-gen).
7. Prioritized actions for the biggest NavBoost lift; offer a monthly re-run as a scheduled task.

Caveats: Chrome-side data is invisible to site owners; CTR baselines vary by vertical and SERP layout; AI Overviews divert clicks at stable positions — compare before/after the AI Overview appeared for the query.
