# Impression Share Gap Finder A skill for finding where impression share is being lost, attributing the cause (budget vs. rank), and prioritizing which gaps are worth closing. ## What this skill does Most Google Ads accounts leave 30–50% of available impressions on the table. This skill: 1. Identifies which campaigns are losing IS to budget (you'd pay if you could) 2. Identifies which campaigns are losing IS to rank (your ad isn't winning the auction) 3. Estimates revenue opportunity if IS reached 90% 4. Calculates incremental daily budget needed for budget-constrained campaigns 5. Diagnoses rank-based losses (bid level, Quality Score, or ad relevance) 6. Outputs a prioritized action plan distinguishing quick wins from "don't bother" campaigns ## Required inputs 1. **Campaign performance data** with impression share columns 2. **Time window** - last 30 days default ### Required columns - Campaign name - Spend, daily budget - Impressions, clicks, CTR - Conversions, CPA, conv. rate, conv. value (if tracking revenue) - Search impression share (IS) - Search IS lost to budget - Search IS lost to rank - Avg. CPC These columns are HIDDEN by default in Google Ads exports. If they're missing, ask the user to re-export with impression share columns enabled (Columns → Modify columns → Competitive metrics → check all IS columns). ## Workflow ### Step 1: Validate data Check that IS columns are present. If they're missing, stop and provide the re-export instructions: > Please
