/digital-marketing-pro:seo-drift

Purpose

Take two snapshots of SEO performance data — separated by weeks, a Core Update, a content refresh, or an algorithm change — and produce a structured drift report: top gainers, top losers, classifications (growth / decline / reshuffle / stable / new / lost), and diagnostic patterns. Works with classic GSC, the new GSC AI Performance Report, rank-tracker exports, and aeo-audit probe results.

Context efficiency

Heavy skill. Grep before Read any referenced file, then Read only matched ranges with offset + limit. List ${CLAUDE_PLUGIN_DATA}/<brand>/ before opening files. On re-invocation mid-session, skip files already in context.

When to Use

• Monthly performance review — last month vs the month before
• Core Update triage — pre-update vs post-update + settling window (use 14+ days after rollout-complete)
• AI Mode citation tracking — quarter-over-quarter aeo-audit outputs to see which queries gained / lost AI Mode citations (Google AI Mode citation diff is a leading indicator for organic decline)
• Content refresh attribution — before vs after a planned content update to attribute lift to the refresh vs other factors
• GSC AI Performance Report — month-over-month deltas on the new (3 Jun 2026) combined AI Overviews + AI Mode report
• Site migration audit — pre-migration baseline vs post-migration settling
