Title Tag Agent Skill
When the user wants to optimize the title tag, page title, or SERP title. Also use when the user mentions "title tag," "meta title," "page title," "SEO title," "SERP title," "browser tab title," "title optimization," "headline for search," "title too long," "title tag length," "duplicate title tags," or "optimize title for CTR." For meta description, use meta-description. For structured data, use schema-markup.

8 sections, as written by the authorSEO On-Page: Title Tag
Guides optimization of the HTML title 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)
- Title tag: Primary search snippet; primary keyword near start; unique per page
Length by Language
Google truncates by pixel width (~580–600px desktop), not character count. Character limits are approximate—CJK chars are wider (~2× Latin), so fewer fit in the same pixels.
| Script / Language | Title (chars) | Notes |
|-------------------|---------------|-------|
| Latin (English, Spanish, French, etc.) | 50–60 | ~55 recommended |
| CJK (Chinese, Japanese, Korean) | 25–35 | Full-width chars; 25–30 desktop; 20–28 mobile; use pixel checker when available |
| Cyrillic (Russian, etc.) | 50–55 | Slightly wider than Latin |
| Arabic, Hebrew | 30–40 | RTL; variable width |
Pixel tools: Use a pixel-accurate checker for CJK—font and locale affect display.
Multilingual: Use locale-specific limits; don't translate then truncate. 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:
- Page type: Homepage, landing, blog, product, etc.
- Primary keyword: Target search query
- Language / script: Apply length rule above
- Brand: Optional brand append at end
Best Practices
| Item | Guideline |
|------|-----------|
| Length | Per language (see table above); Google truncates beyond ~600px |
| Front-load | Main phrase first; branding at end |
| Keyword | Include primary keyword near the start |
| Unique | One unique title per page |
| Clarity | Match search intent; avoid keyword stuffing |
| Engagement | Numbers, power words, questions can boost CTR ~36% |
| H1 alignment | H1 should align with title; Google may rewrite titles if they mismatch content or intent |
Example: Bad: "SEO Tips for Small Business" → Better: "11 SEO Tips That Actually Work (2026)"
Output Format
- Recommended title (with character count for target language)
- Alternatives (if A/B testing)
