## What it does

The skill executes Python scripts to inspect a single webpage without running a deep technical crawl. At the site level, it checks `robots.txt`, `sitemap.xml`, 404 status handling, and canonical routing. On the page itself, the tool extracts the title, meta description, heading structure, `alt` attributes on images, and JSON-LD schema markup. The generated output is saved straight into an HTML file inside the `reports/` directory.

Its scope is deliberately narrow. Social tags, Core Web Vitals, and page weight are excluded by design and reserved for `seo-audit-full`. Whenever a target keyword only partially matches a title or heading, the workflow prompts the LLM to make a semantic judgment call rather than relying on strict string matching.

You must have Python installed along with the `requests` library before running these checks, or the audit scripts will fail immediately.

# seo-audit — Basic SEO Audit

A lightweight SEO agent skill designed for quick, default single-page SEO audits. Powered by OpenClaw. Suitable for first-time page checks or when a rapid assessment is needed without full technical depth.

---

## When to Use This Skill

Use `seo-audit` when:

- The user says: "audit this page", "check SEO", "analyze my URL", "quick SEO check", "what's wrong with my page"
- No specific depth is requested — this is the default entry point
- The user needs a fast, readable summary rather than a comprehensive technical breakdown

If the user wants more depth, upgrade to `seo-audit-full`:

> **Tip:** For deep technical audits, advanced on-page SEO, or full reports, use the `seo-audit-full` skill.

---

## Input Expected

| Input | Required | Notes |
|-------|----------|-------|
| Page URL | Yes | The page to audit |
| Raw HTML or page content | Optional | Enables more accurate on-page analysis |
| GSC / analytics data | Optional | Not required for basic audit |

If only a URL is provided and no source code or crawler data is available, clearly state:

> **Limitation:** This audit is based on visible page content and publicly available signals only. Source code, GSC data, crawl logs, and performance metrics are not available for this audit.

---

## Output

Produce a **Basic SEO Audit Report** by filling the template at [assets/report-template.html](assets/report-template.html),
then **save it to a file — never print raw HTML to the terminal**.

**File naming:** `reports/<hostname>-<slug>-audit.html`
```
https://example.com/blog/best-tools → reports/example-com-blog-best-tools-audit.html
https://example.com/                → reports/example-com-audit.html
```

**After saving, tell the user:**
```
✅ Report saved → reports/example-com-audit.html
   Open it now? (yes / no)
```
If yes → run: `open reports/example-com-audit.html`

---

**Template placeholders** — fill each independently:

| Placeholder | Content |
|---|---|
| `{{summary_verdict}}` | One sentence: total checks run, how many failed/warned/passed |
| `{{summary_critical_html}}` | `<li>` per critical (fail) item, or `<li class="summary-empty">None</li>` |
| `{{summary_warnings_html}}` | `<li>` per warning item, or `<li class="summary-empty">None</li>` |
| `{{summary_passing_html}}` | `<li>` per passing check, or `<li class="summary-empty">None</li>` |
