# Technical SEO Checker


This skill performs comprehensive technical SEO audits to identify issues that may prevent search engines from properly crawling, indexing, and ranking your site.

## What This Skill Does

Audits crawlability, indexability, Core Web Vitals, mobile-friendliness, HTTPS/security, structured data, URL structure, and international SEO with scored results and a prioritized fix roadmap.

## Quick Start

Start with one of these prompts, then finish with the standard handoff summary from [Skill Contract](../../../references/skill-contract.md).

### Full Technical Audit

```
Perform a technical SEO audit for [URL/domain]
```

### Specific Issue Check

```
Check Core Web Vitals for [URL]
```

```
Audit crawlability and indexability for [domain]
```

### Pre-Migration Audit

```
Technical SEO checklist for migrating [old domain] to [new domain]
```

```
Pre-migration audit: WordPress to Next.js headless
```

The migration flow has 6 stages (baseline snapshot, risk map, redirect map, staging QA, cutover checklist, T+1/T+7/T+30 diff). See [references/pre-migration-playbook.md](references/pre-migration-playbook.md) for the full workflow and red-flag patterns.

### LLM Crawler Handling (GPTBot / ClaudeBot / PerplexityBot)

```
Audit how my site handles AI crawlers — I want to allow retrieval but block training
```

As of 2026, robots.txt must make explicit decisions about AI engines. See [references/llm-crawler-handling.md](references/llm-crawler-handling.md) for the bot inventory, three stance patterns (default-open, default-closed, split), robots.txt templates, and the Cloudflare edge-override gotcha.

### Site-Wide / Bulk Audit (5+ URLs)

For e-commerce and large sites (e.g., "40 of 50 products not indexed"), switch to bulk mode — sample per URL pattern, report pattern-level findings, deliver portfolio priority instead of per-URL output:

```
Bulk audit: 50 product pages on example.com, 40 not indexed
```

```
Audit all URLs in https://example.com/sitemap.xml
```

See [references/bulk-audit-playbook.md](references/bulk-audit-playbook.md) for the full workflow. For platform-specific playbooks (Shopify / WooCommerce / Headless / BigCommerce / Magento 2), see [references/ecommerce-platform-patterns.md](references/ecommerce-platform-patterns.md).

## Skill Contract

**Expected output**: a scored diagnosis, prioritized repair plan, and a short handoff summary ready for `memory/seo-geo/tune/technical-seo-checker/`.

- **Reads**: target URLs or domain, PageSpeed/CrUX reports, robots.txt, sitemap, and reported symptoms.
- **Writes**: a user-facing audit or optimization plan plus a reusable summary that can be stored under `memory/seo-geo/tune/technical-seo-checker/`.
- **Promotes**: blocking defects, repeated weaknesses, fix priorities, and pending decisions to `memory/open-loops.md`.
- **Done when**: each audited area carries evidence, issues, fixes, and
