| 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 |

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.
