Google Ads Impression Share Analysis (Read-Only)

For the Google Ads account the user names, analyze impression-share metrics across all active campaigns. Read-only — recommends only, never adjusts budgets or bids.

If the user didn't name an account, list their connected accounts and ask which one to use.

Constraints (do not violate)

• Only consider campaigns with ≥ 30 conversions in last 30 days. Below that, the signal is too noisy.
• Do not recommend budget increases for campaigns with CPA > 1.2× target. Throwing money at unprofitable campaigns wastes money.
• Do not recommend bid increases if already above target CPA. Same logic.
• Prioritize profitable scaling only.

Inputs (per campaign, last 30d)

• Search Impression Share
• Lost IS (Budget)
• Lost IS (Rank)
• Conversion volume + CVR
• CPA vs target
• ROAS
• Current daily budget

Analysis buckets

Bucket A — Scaling opportunity (high Lost-IS Budget + strong CPA)

• Lost IS (Budget) ≥ 20% AND CPA ≤ target
• Recommendation: budget increase. Suggest exact % based on how much budget headroom the IS gap implies.

Bucket B — Bid / relevance issue (high Lost-IS Rank + good CVR)

• Lost IS (Rank) ≥ 20% AND CVR ≥ campaign median
• Recommendation: bid adjustment OR ad-strength / quality-score work. Suggest which.

Bucket C — Overexposure (high IS + poor CPA)

• Search IS ≥ 75% AND CPA > target
• Recommendation: HOLD. Do not scale. Profitability problem, not a reach problem.

Bucket D — Healthy (high IS + good CPA)

• Search IS ≥ 80% AND CPA ≤ target
• Recommendation: monitor. You're maxed out on demand for current keywords; growth requires new keyword expansion or new campaign types.

Output format

Three sections, each a vertical list:

📈 Scale (recommend budget increase)

• [Campaign] — Lost IS (Budget) 32%, CPA 22% under target. Suggest +30% budget, expected +N conversions/day.

🔧 Fix (recommend bid / quality work)

• [Campaign] — Lost IS (Rank) 28%, strong CVR. Suggest bid +15% OR ad-copy refresh — ad strength is "Average".

🛑 Hold (no action recommended)

• [Campaign] — Overexposed (IS 88%, CPA 38% above target). Fix profitability before scaling.

For each campaign that hits the conversion-volume floor (< 30 conv / 30d), exclude it silently.

End with: _All recommendations — no budgets or bids changed. Ask explicitly to enact any of these._
