## Summary

| Audit Area | Score | Key Finding |
|------------|-------|-------------|
| Title Tag | 8/10 | Good keyword placement; slightly long at 63 chars |
| Meta Description | 6/10 | Missing CTA; keyword present but generic copy |
| Header Structure | 9/10 | Clean hierarchy; H2s cover all major products |
| Content Quality | 7/10 | 2,400 words is solid; lacks original test data |
| Keyword Optimization | 8/10 | Strong placement; density at 1.2% is healthy |
| Internal Links | 5/10 | Only 2 internal links; missing links to brand pages |
| Images | 6/10 | 3/8 images missing alt text; no WebP format |
| Technical Elements | 7/10 | Missing Product schema; good URL and mobile |

## Overall Score: 71/100

Calculation: (8x0.15 + 6x0.05 + 9x0.10 + 7x0.25 + 8x0.15 + 5x0.10 + 6x0.10 + 7x0.10) x 10 = 71

Score Breakdown:
████████░░ Title Tag:        8/10  (15%)
██████░░░░ Meta Description: 6/10  ( 5%)
█████████░ Headers:          9/10  (10%)
███████░░░ Content:          7/10  (25%)
████████░░ Keywords:         8/10  (15%)
█████░░░░░ Internal Links:   5/10  (10%)
██████░░░░ Images:           6/10  (10%)
███████░░░ Technical:        7/10  (10%)

## Priority Issues

### Critical
1. **Internal linking severely underdeveloped** — Only 2 internal links found. Add links to individual headphone review pages (/sony-wh1000xm5-review, /bose-qc-ultra-review) and the headphones category page. Target 5-8 contextual internal links.
2. **3 product images missing alt text** — Images for Sony WH-1000XM5, Bose QC Ultra, and Apple AirPods Max have empty alt attributes. Each missing alt tag is a lost ranking signal in Google Images.

### Important
1. **Meta description lacks call-to-action** — Current description states facts but does not compel clicks. Add "Compare prices and features" or "See our top picks" to drive CTR.

## Quick Wins

1. **Add alt text to 3 images** (5 min) — Use descriptive text like "Sony WH-1000XM5 noise cancelling headphones on desk" instead of empty attributes.
2. **Rewrite meta description with CTA** (5 min) — Change to: "Compare the 10 best noise cancelling headphones for 2025. Expert-tested picks from Sony, Bose, and Apple with pros, cons, and pricing. See our top picks."
3. **Add 4+ internal links** (10 min) — Link product names to their individual review pages and add a "See all headphones" link to the category hub.
```

## Scoring Rubric

### Section Weight Distribution

| Audit Section | Weight | Max Score | Rationale |
|--------------|--------|-----------|-----------|
| Title Tag | 15% | 15 | Strongest single ranking signal |
| Meta Description | 5% | 5 | CTR impact, not direct ranking factor |
| Header Structure | 10% | 10 | Content organization, semantic signals |
| Content Quality | 25% | 25 | Strongest holistic ranking factor |
| Keyword Optimization | 15% | 15 | Relevance signals |
| Internal/External Links | 10% | 10 | Authority flow, context signals |
| Image Optimization | 10% | 10 | Accessibility + image search opportunity |
| Page-Level Technical | 10% | 10 | Core Web Vitals, mobile, security |

### Scoring Scale per Factor

| Score | Meaning | Action Required |
|-------|---------|-----------------|
| 10/10 | Excellent — follows all best practices | None |
| 7-9/10 | Good — minor improvements possible | Optional optimization |
| 4-6/10 | Needs work — notable issues | Fix within this week |
| 1-3/10 | Poor — significant problems | Fix immediately (Critical) |
| 0/10 | Missing or broken | Fix immediately (Blocking) |

### Scoring Conversion Formula

Each section is scored out of 10, then converted to the 100-point overall score using section weights:

```
Overall Score = Sum of (section_score x section_weight) x 10
```

Where section weights are: Title 0.15, Meta 0.05, Headers 0.10, Content 0.25, Keywords 0.15, Links 0.10, Images 0.10, Technical 0.10.

**Worked example:**

| Section | Score /10 | Weight | Weighted |
|---------|-----------|--------|----------|
| Title Tag | 8 | 0.15 | 1.20 |
| Meta Description | 6 | 0.05 | 0.30 |
| Header Structure | 9 | 0.10 | 0.90 |
| Content Quality | 7 | 0.25 | 1.75 |
