What it does

Technical SEO is an agent skill from gtmagents/gtm-agents. Use when diagnosing crawl/index issues, performance regressions, or structured data gaps.

Its SKILL.md is about 710 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Marketing & SEO, covering Technical SEO, Schema markup and Web performance. The repository describes itself as: Production-ready collection of GTM agents and specialized skills for claude code. Covers sales, marketing, customer success, and revenue operations workflows. The licence is Apache-2.0.

When your agent uses it

  • Diagnosing crawl/index issues
  • Performance regressions
  • Structured data gaps

Example prompts

  • “/technical-seo”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

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

What it can do on your machine

Read from SKILL.md and the folder at commit 78e0419. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Technical SEO loads about 705 tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 332 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~26
When it runs · the whole SKILL.md, loaded when a task matches
~705

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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

  1. Crawl Health – Screaming Frog/JetOctopus results, search console coverage, log file sampling.
  2. Performance – Lighthouse field vs lab data, render-blocking assets, code splitting, image optimization.
  3. Indexation & Signals – robots.txt, canonicals, hreflang, pagination, parameter handling.
  4. Structured Data – schema coverage, errors, merchant/product feeds.
  5. 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

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

KPI Guardrails

  • Organic sessions: ±10% vs trailing 4-week baseline (alert beyond 15%).
  • Priority keyword avg rank: no more than 2 position drop for Tier-1 terms.
  • Conversion contribution: must stay within 5% of forecasted pipeline; otherwise notify Growth + Sales.
