SEO Mods — Development skill for Claude Code

SEO Mods for Claude Code

Three Claude Code mods for SEO work: live rankings while Claude works, a guard against keyword cannibalization, and a filter that keeps AI slop off your pages.

• Client Pulse: a band above the prompt showing the client's Search Console clicks and impressions (week over week), tracked keyword movement, AI citations and the top opportunity query.
• Cannibalization Guard: stops Claude from creating a new page for a keyword your site already covers or ranks for, and tells it to improve the existing page instead.
• Slop Filter: scores every page Claude writes for AI tells and SEO cliches ("look no further", "nestled in the heart of", "it's not just X, it's Y"), in English and Spanish, and makes Claude rewrite anything that reads like AI. No data source needed, no tokens used.

Client Pulse and Cannibalization Guard read their data from [DataWise SEO](https://www.datawiseseo.com/) through its Claude connector.

Requirements

• Claude Code: a recent version (mods are new; run claude update).
• DataWise SEO: connected in Claude, with your client's Search Console property synced.
• DataForSEO (optional): the Guard's "which URL already ranks" lookup uses ranked keywords through DataWise, about one call per domain per day. Get DataForSEO here.
