SEO 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 / LanguageTitle (chars)NotesLatin (English, Spanish, French, etc.)50–60~55 recommendedCJK (Chinese, Japanese, Korean)25–35Full-width chars; 25–30 desktop; 20–28 mobile; use pixel checker when availableCyrillic (Russian, etc.)50–55Slightly wider than LatinArabic, Hebrew30–40RTL; 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:

1. Page type: Homepage, landing, blog, product, etc.
2. Primary keyword: Target search query
3. Language / script: Apply length rule above
4. Brand: Optional brand append at end
