# SEO Page — Deep Single-Page Analysis

When user provides a single URL for review (not a full site audit).

---

## ANALYSIS SCOPE

Fetch the page and analyze all aspects:

### 1. On-Page Elements
- Title tag: present, length (50-60 chars), keyword placement, unique
- Meta description: present, length (150-160 chars), compelling, CTA
- H1: present, single, contains primary keyword, different from title
- H2-H6 hierarchy: logical structure, no skipped levels
- URL slug: descriptive, keyword-relevant, clean

### 2. Content Quality
- Word count vs competitors for target keyword
- Readability: sentence length, paragraph length
- Keyword usage: natural, not stuffed (density < 2-3%)
- Internal links: how many, to relevant pages?
- External links: to authoritative sources?
- Freshness: last modified date, content currency

### 3. Technical
- Canonical tag (self-referencing?)
- robots meta (index, follow?)
- Open Graph tags (for social sharing)
- Twitter Card tags
- Viewport meta tag
- Language declaration

### 4. Schema
- What schema types are present?
- Are they valid?
- What's missing for this page type?
- Generate suggested JSON-LD

### 5. Images
- All images have alt text?
- Images optimized (format, size)?
- LCP image identified and optimized?

### 6. Performance (if PSI key available)
- Run PSI for this specific URL
- CrUX data for this URL (if available)

### 7. Internal Link Context (if crawl data available)
- How many pages link TO this page?
- How deep is this page (clicks from home)?
- What anchor text is used to link here?
