## Capabilities

- Audits crawlability, robots.txt, sitemaps, redirects, and orphan-page patterns.
- Reviews indexability signals, including noindex directives, canonicals, duplicates, and HTTP failures.
- Evaluates LCP, INP, CLS, mobile usability, HTTPS, and security headers.
- Checks URL structure, structured data, hreflang, and AI crawler policies.
- Supports bulk URL audits and pre-migration workflows with prioritized findings.
- Labels evidence as measured, user-provided, estimated, or unavailable.

## Use Cases

- Diagnose an indexing decline: Review crawl barriers, canonical conflicts, status codes, and sitemap coverage after organic traffic drops.
- Prepare a site migration: Build a baseline, redirect map, staging checklist, cutover plan, and post-launch comparison.
- Audit an ecommerce catalog: Sample URL patterns, identify template-level defects, and prioritize fixes by affected page count.

## Prompt Templates

### Check one page

```
Check Core Web Vitals and indexability for [URL]. Label each metric source and list the three highest-priority fixes.
```

### Audit a domain

```
Perform a technical SEO audit for [domain]. Score each area, cite evidence, and separate measured results from estimates.
```

### Review a large catalog

```
Bulk audit URLs from [sitemap]. Group patterns, sample representative pages, estimate affected counts, and produce a portfolio priority queue.
```

### Plan a migration

```
Create a pre-migration audit from [old domain and stack] to [new domain and stack], including redirects, staging checks, launch gates, and monitoring.
```

## Limitations

- Live measurements require connected tools, supplied reports, or permission to fetch target URLs.
- JavaScript-rendered content may require the documented rendering helper or another browser-based tool.
- The skill does not replace Search Console access, server logs, or professional security testing.
- Recommendations require human review before production configuration or index submissions.

## Best Practices

- Provide target URLs, business-critical templates, and recent tool exports when available.
- Confirm whether results may be fetched, rendered, stored, or submitted to external services.
- Retest representative URLs after fixes and compare against the original evidence.

## Anti Patterns

- Do not present estimated metrics as measured results.
- Do not apply broad robots.txt or canonical changes without testing affected patterns.
- Do not submit URLs or contact external services without explicit approval.

## Security Audit

- Audited at: 2026-07-12T14:13:48.453\+00:00
- Summary: Most static findings are Markdown fences, relative documentation links, placeholders, or SEO checklist text. Five findings are confirmed: four executable command recipes and one outbound-network use at SKILL.md lines 98-104; no prompt injection or malicious intent was found.
