What the SEO Audit skill actually is?

A multi-agent site crawler, not a single pass

The seo-audit skill is a multi-agent crawler that fetches your homepage, detects your business type (SaaS, local services, e-commerce, publisher, or agency), crawls up to 500 pages respecting robots.txt, then delegates findings to up to 15 specialist subagents running in parallel.

Specialist agents activate based on detected signals: local SEO agents spawn for brick-and-mortar businesses, e-commerce agents for product sites, and clustering analysis for content-heavy sites. Google and backlink agents activate only when API credentials are present.

Every audit ends with two deliverables: a comprehensive findings document and a prioritized action plan sorted by impact and implementation effort. Both are markdown files you can commit directly into your repo.

When it Triggers?

Triggers on /seo audit <url>, or when you say 'full SEO audit', 'website SEO check', 'audit my site', or 'SEO health check'. Pass a domain to crawl from the root, or a specific path to start there.

Without API credentials it runs the full on-page analysis, technical checks, schema validation, and content review. Optional keys for DataForSEO, Google Search Console, and Moz unlock live SERP data and backlink profiles.

What it delivers

From crawl to actionable report

01

Site detection and crawl

Fetches homepage, identifies business type, and crawls up to 500 pages respecting robots.txt and rate limiting. Partial results are delivered when pages are unreachable.

02

Parallel specialist delegation

Spawns up to 15 specialist subagents covering technical SEO, content, schema, performance, AI readiness, and conditionally local, e-commerce, and backlink agents.

03

0-100 health score

Calculates the weighted SEO health score across seven categories. Each category is independently scored by its specialist and combined into the final weighted total.

04

Two-document output

Produces a comprehensive findings report with evidence and a prioritized action plan with Critical-to-Low severity tiers. Both are ready-to-commit markdown files.
