English · 中文 · SEO Audit Agent Skill
Reusable Agent Skills for single-page SEO auditing. Give it a URL — get a structured HTML report with actionable findings.
Built on a Script + LLM two-layer architecture: Python scripts handle deterministic checks (HTTP status, XML parsing, string matching), while the LLM handles semantic judgment (keyword intent, content quality, page type inference). Works with Claude Code, Cursor, and any agent runtime that supports SKILL.md.
Best practices
- Run
npx skills add JeffLi1993/seo-audit-skill, then audit your page (for example:audit this page: https://example.com). Open the report atreports/<hostname>-audit.htmland review it yourself: keep what matters for your goals, skip what does not. - Share the report (or the key sections) with Cursor or Claude Code and have the assistant work through the findings and fixes item by item.
Report Output
Each basic audit produces a standalone HTML report saved to reports/<hostname>-audit.html.
Full audits save to reports/<hostname>-full-audit.html.
| Section | What you get |
|---|---|
| Audit Summary | One-line verdict + critical / warnings / passing at a glance |
| Site Checks | Sitemap URL Inventory · Crawlability · URL Canonicalization · i18n · Schema · E-E-A-T |
| Page Speed | Full only — Lighthouse scores, lab metrics, final URL, screenshot availability |
| Page Checks | TDK · H1 · Headings · Word Count · Internal Links · Social Tags |
| Priority Actions | Top 3 highest-impact fixes, ranked |
| Insight Walkthrough | Evidence → Impact → Fix for each major finding |

Skills
| Skill | Tier | When to use |
|---|---|---|
seo-audit | Basic | Default — give it a URL, get a 20+ check structured report |
seo-audit-full | Full | Deep audit with PageSpeed, sitemap inventory, social tags, content quality, GSC data, competitor gap |
seo-audit-fullrequires a Google PageSpeed Insights API key for PageSpeed checks. SetPAGESPEED_API_KEY/GOOGLE_PAGESPEED_API_KEY, or pass--api-key; without a key, the full audit stops and asks you to configure one.
Audit Coverage
Site-level
| Check | What it verifies | Basic | Full |
|---|---|---|---|
| Sitemap URL Inventory | Standalone table of top sitemap directories: URL count, page type, representative example URL | — | ✅ |
| Staging Subdomain Indexation | Detects public test., staging., dev., preview., beta., uat. hosts that mirror production and may be indexable | — | ✅ |
| robots.txt | RFC 9309 group parsing, Allow/Disallow logic, Googlebot status, Sitemap directives | ✅ | ✅ |
| sitemap.xml | Valid XML, URL count, follows Sitemap directive path from robots.txt, samples child sitemap URLs when needed | ✅ | ✅ |
| 404 Handling | True 404 vs soft 404 (200) vs redirect-to-homepage (301) | ✅ | ✅ |
| URL Canonicalization | HTTP→HTTPS redirect, www consistency, trailing slash, canonical tag match | ✅ | ✅ |
| i18n / hreflang | Reciprocal symmetry, BCP 47 codes, x-default, default-language URL duplication, canonical/hreflang alignment | ✅ | ✅ |
| Schema (JSON-LD) | Parseability, @type detection, required/recommended fields, nested fields, type conflicts, localized schema language/URL alignment | ✅ | ✅ |
| E-E-A-T Trust Pages | About / Contact / Privacy / Terms — exists (HTTP 200) + reachable from footer/nav | ✅ | ✅ |
| GSC Crawl Status | Index coverage, crawl errors, blocked resources | — | ✅ |
| PageSpeed / Lighthouse | Performance · Accessibility · Best Practices · SEO scores, lab metrics, final URL, screenshot availability | — | ✅ |
Sitemap URL Inventory is intentionally rendered as its own table before Crawlability:
| Directory | URL Count | Page Type | Example Page |
|---|---|---|---|
/blog/ | 300 | Blog / Content Pages | https://xx.ai/blog/best-ai-video-tools |
/tools/ | 80 | Tool Pages | https://xx.ai/tools/image-generator |
/alternatives/ | 40 | Alternative / Competitor Pages | https://xx.ai/alternatives/synthesia |
Use it as a site-level map, then choose representative URLs from important directories for deeper full audits.
Page-level
| Check | What it verifies | Basic | Full |
|---|---|---|---|
| URL Slug | Lowercase, hyphenated, keyword present, stop word & stuffing detection | ✅ | ✅ |
| Title Tag | 50–60 chars, keyword position, homepage vs inner page rules | ✅ | ✅ |
| Meta Description | 120–160 chars, keyword match, concrete value prop (not generic fluff) | ✅ | ✅ |
| H1 Tag | Single H1, keyword match (full / partial / none), semantic intent review | ✅ | ✅ |
| Canonical Tag | Self-referencing, matches final URL after redirects | ✅ | ✅ |
| Image Alt Text | Alt attribute check on all <img>, JS-render detection | ✅ | ✅ |
| Word Count | Body text ≥ 500 words, thin content flag | ✅ | ✅ |
| Keyword Placement | Primary keyword within first 100 body words | ✅ | ✅ |
| Heading Structure | H2 count (target 5–7), H3/H2 ratio, keyword distribution in H2s | ✅ | ✅ |
| Internal Links | Same-origin links (excl. nav/footer), equity distribution | ✅ | ✅ |
| OG / Social Tags | og:image, twitter:card, social preview completeness | — | ✅ |
| Content Quality | E-E-A-T depth, readability, specificity vs competitors | — | ✅ |
