blog-cannibalization
Detect keyword cannibalization across blog posts by extracting primary keywords from titles and headings, clustering semantically similar targets, and flagging posts competing for the same search intent. Supports local-only mode (grep-based) and DataForSEO API mode (Page Intersection endpoint at ~$0.01/call). Outputs severity-scored report with merge or differentiate recommendations. Use when user says "cannibalization", "keyword overlap", "competing pages", "duplicate keywords", "cannibalize".
npx skills add AgriciDaniel/claude-blog --skill blog-cannibalization --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Blog Cannibalization - Keyword Overlap Detection Detect when multiple blog posts compete for the same search keywords. Two modes: local-only analysis (default) and DataForSEO API mode for SERP-level data. ## Two Modes | Mode | Flag | Cost | Data Source | |------|------|------|-------------| | Local | (default) | Free | File content analysis via Grep/Read | | API | `--api` | ~$0.01/call | DataForSEO Page Intersection + Ranked Keywords | Local mode works without any API keys. API mode requires DataForSEO credentials set as environment variables: `DATAFORSEO_LOGIN` and `DATAFORSEO_PASSWORD`. ## Local Mode Workflow ### Step 1: Scan Blog Files Use Glob to find all content files in the target directory: - Patterns: `**/*.md`, `**/*.mdx`, `**/*.html` - Skip files in `node_modules/`, `.git/`, `drafts/` ### Step 2: Extract Primary Keywords For each file, read and extract keyword signals from: - **Title tag** or H1 heading (highest weight) - **H2 headings** (medium weight) - **First paragraph** (supporting signal) - **Meta description** if present in frontmatter Primary keyword extraction method: 1. Tokenize title, H1, H2s, meta description, and first paragraph into 1-gram, 2-gram, and 3-g

How do I install it?

Where does this skill come from?
From AgriciDaniel/claude-blog, a repository with 1,566 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
