Technical SEO Playbooks

When to Use

Sites experiencing ranking drops despite strong content.
Launching major site changes (CMS migrations, redesigns).
Investigating Core Web Vitals, crawl budget, or indexing issues.

Framework

Crawl Health – Screaming Frog/JetOctopus results, search console coverage, log file sampling.
Performance – Lighthouse field vs lab data, render-blocking assets, code splitting, image optimization.
Indexation & Signals – robots.txt, canonicals, hreflang, pagination, parameter handling.
Structured Data – schema coverage, errors, merchant/product feeds.
Security & Compliance – HTTPS, mixed content, cookie banners, accessibility.

Playbooks

Migrations – pre/post launch checklist, redirect maps, monitoring dashboards.
CWV Improvements – prioritized backlog (LCP, INP, CLS fixes) with eng dependencies.
International SEO – hreflang matrix, localized sitemaps, translation QA.
GTM Agents Audit Checklist – five-pass review (crawl → index → performance → schema → reporting) @puerto/README.md#183-212.
Issue Escalation Flow – Marketing Director ↔ DevOps ↔ Content to fast-track blocking defects.

Templates

Crawl issue tracker (URL, issue, severity, owner, status).
Core Web Vitals monitoring dashboard.
Structured data coverage sheet.
KPI guardrail sheet (sessions, rankings, conversions) with "alert" thresholds matching GTM Agents governance cadence.

Tips

Pair log-file analysis with Search Console stats to confirm real-world crawl behavior.
Automate regression alerts via Lighthouse CI or SpeedCurve.
Document every infra change with timestamp to correlate with ranking volatility.
Share Guardrail snapshots weekly using GTM Agents-style status packet (target vs actual vs guardrail) to keep Sales + Execs aligned.
Trigger rollback when three guardrail breaches occur in 24h or when crawl errors spike >25% vs baseline.

GTM Agents SEO Escalation Workflow

Detection – SEO specialist flags issue via crawl report or KPI guardrail breach.
Triage – assign severity (P0-P2) + owner across Engineering, Content, or RevOps.
Action – implement fix, document via Serena patch or CMS change log.
Validation – rerun crawl/perf audits, update structured data validator.
Comms – send 3-point summary (issue, fix, KPI impact) in status packet.
