About this skill

What is the Technical SEO skill?

The Technical SEO skill is how Moonrank's SEO Agent inspects the layer under the content: whether Google can crawl the site, render its JavaScript, resolve its canonicals and redirects, and index the pages that matter — with every finding traced to the template or rule causing it.

It's written as a SKILL.md, a plain-language instruction format that people and AI agents can both follow. Read it to run the checks yourself, hand it to your developers as an audit scope, or let the SEO Agent run it end to end.

Downloading the playbook is free with a Moonrank account. Re-running it on every deploy and migration, before problems reach the index, is what the SEO Agent does continuously.

Example

See it in action

You ask

“We moved to a new JavaScript framework and half our pages disappeared from Google. Help.”

Agent does

Your product descriptions and internal links only exist in the rendered DOM — raw HTML ships an empty shell, and 2,300 URLs fell out of the index over six weeks. On top of that, the new router 307s every trailing-slash URL, adding a hop to 100% of internal links. Ship server-side rendering on the product template first, then flatten the redirect rule — the first fix alone recovers most of the loss.

How it works

From input to fix list

  1. 1

    You provide the domain

    Plus Search Console coverage and server logs if you have them — they sharpen the indexation diagnosis.

  2. 2

    Moonrank crawls as Googlebot

    Status codes, robots rules, redirect chains, and a diff of raw HTML against the rendered DOM.

  3. 3

    It traces every gap to a cause

    Each missing or dropped URL is explained — noindex, canonical, rendering, quality, or discovery.

  4. 4

    It returns fixes by template

    Findings grouped by root cause, written as changes a developer can ship, then verified by re-crawl.

What's included

Everything it checks

Googlebot crawl

Status codes, robots rules, crawl traps, and redirect chains across the whole site.

Render diff

Raw HTML against rendered DOM, catching content and links that only exist after JavaScript.

Indexation reconciliation

Every gap between crawlable and indexed, with the specific reason named.

Canonical and redirect tracing

Chains followed to the end; loops, long chains, and canonicals pointing at redirects flagged.

Core Web Vitals per template

Failures measured where users are, with the blocking resource named.

Template-level fix list

Root causes grouped so one change fixes hundreds of pages, verified by re-crawl.

Use cases

When to reach for it

  • Recover pages that dropped out of the index after a framework change.
  • De-risk a migration or redesign before it ships.
  • Explain why published pages never get indexed.
  • Turn a Core Web Vitals failure into a named resource to fix.
  • Give developers SEO tickets specific enough to estimate and ship.
Questions

Frequently asked questions

It's the SEO methodology Moonrank's SEO Agent follows — written out step by step, so you can read exactly how the work gets done rather than trusting a black box.

A plain-language instruction file that both people and AI agents can follow. Open it in any editor, paste it into Claude or ChatGPT, or drop it into an agent framework that reads skill files.

Yes. Every skill file is free with a Moonrank account — we ask for an email, not a credit card. Running the skill continuously against your site is what the paid product does.

Absolutely. The file is yours to adapt. Hand it to your team as a standard, run it manually, or point your own agent at it. Nothing in it depends on our platform.

The SEO Agent runs this methodology against your site on a schedule, prioritizes what it finds, and ships copy-ready fixes — no manual runs, no downloads to manage.
