seo-headings-structure

75 / 100 · Review before installing

Check before installing. Some of what it can do is expected: a marketing skill usually talks to online services.

By Hainrixz/claude-seo-ai (GitHub) · marketing · 87 stars · scanned at commit 0a7ef08

Audit and propose fixes for a page's heading hierarchy and semantic outline — verify exactly one H1, logical H2-H6 nesting with no skipped levels, descriptive heading text, and HTML5 landmarks (article/section/nav/main/footer) — so the document outline is extractable. Module M7c. Feeds the Search SEO score (clean headings also support AI answer-block extraction, which is scored separately under M11).

Works with any agent that supports SKILL.md skills.

if [ -e ~/.agents/skills/'seo-headings-structure' ] || [ -L ~/.agents/skills/'seo-headings-structure' ]; then echo 'A skill folder named seo-headings-structure already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/Hainrixz/claude-seo-ai' "$d" && git -C "$d" checkout --quiet '0a7ef08986eabfa6452f7055cddb6582d074b9d7' -- 'skills/seo-headings-structure' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/seo-headings-structure' ~/.agents/skills/'seo-headings-structure' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'seo-headings-structure' ~/.claude/skills/'seo-headings-structure' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
