# SEO On-Page: Meta Description

Guides optimization of the meta description tag for search engines and SERP display.

**When invoking**: On **first use**, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On **subsequent use** or when the user asks to skip, go directly to the main output.

## Scope (On-Page SEO)

- **Meta description**: CTA; unique value; target keyword; unique per page

## Length by Language

Google truncates by **pixel width** (~920px desktop, ~680px mobile), not character count. Character limits are approximate—CJK chars are wider (~2× Latin), so fewer fit in the same pixels.

| Script / Language | Meta description (chars) | Notes |
|-------------------|--------------------------|-------|
| **Latin** (English, Spanish, French, etc.) | 150–160 | Desktop ~158; mobile ~120 |
| **CJK** (Chinese, Japanese, Korean) | 75–100 | Full-width chars; 70–80 conservative; 90–100 on some locales/fonts; use pixel checker when available |
| **Cyrillic** (Russian, etc.) | 140–155 | Slightly wider than Latin |
| **Arabic, Hebrew** | 70–90 | RTL; variable width |

**Pixel tools**: Use a pixel-accurate meta tag checker for CJK—font and locale affect display; character counts vary by source (65–80 to 90–120 in practice).

**Multilingual**: Use locale-specific limits; localize, don't just translate. See **localization-strategy**, **translation**.

## Initial Assessment

**Check for project context first:** If `.claude/project-context.md` or `.cursor/project-context.md` exists, read it for brand voice and target keywords.

Identify:
1. **Page type**: Homepage, landing, blog, product, etc.
2. **Primary keyword**: Target search query
3. **Language / script**: Apply length rule above
4. **CTA**: Primary action (sign up, learn more, buy, etc.)

## Best Practices

| Item | Guideline |
|------|-----------|
| **Length** | Per language (see table above); ~150 chars sweet spot for Latin; truncates beyond pixel limit |
| **Unique** | One per page; no duplicate descriptions |
| **Intent** | Answer "why should I click?"; match search intent |
| **CTA** | Include clear call-to-action when relevant |
| **Keyword** | Naturally include target keyword |
| **Content** | Include author, date, price where relevant |
| **Impact** | Does not affect ranking; well-written descriptions improve CTR 5–10% |

## Output Format

- **Recommended meta description** (with character count for target language)
- **Alternatives** (if A/B testing)
