Overview
SEO On-Page: Title Tag Skill is an open-source Agent Skill from the kostja94/marketing-skills collection (MIT). It teaches AI coding agents focused marketing / SEO workflows so they can produce production-ready guidance instead of generic advice.
Guides optimization of the HTML title tag for search engines and SERP display.
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.
Official skill id: title-tag. Source path: skills/seo/on-page/title.
