## Prompt

```markdown
## Task

Use @Google Ads/List Campaigns to get all campaigns, then @Google Ads/List Ad Groups to break down each campaign into ad groups. Finally, use @Google Ads/List Ads to pull every ad with its creative assets and performance data. Analyze which headlines and descriptions are working and which need replacing.

## Input

The user provides their Google Ads client customer ID and optionally a date range or specific campaigns to audit.

**Example:** "Audit all the ads in my Google Ads account 123-456-7890. Show me which headlines and descriptions are performing best and worst over the last 30 days."

## Context

### What to Audit

**Creative performance signals:**
- Responsive search ad headline combinations with highest CTR
- Description lines that drive conversions vs. those that don't
- Ad strength ratings across the account
- Ads that haven't been updated in 90+ days

**Cross-campaign patterns:**
- Which messaging themes perform best across campaigns
- Headlines that work in one campaign but fail in another
- Description patterns that consistently drive higher conversion rates
- Ad groups running with fewer than 3 active ads

**Ad format considerations:**
- Responsive search ads with low ad strength ratings
- Pinned headlines reducing Google's optimization ability
- Description lines that repeat headline messaging
- Call-to-action consistency across ad groups

### Analysis Strategy

1. List all campaigns and their ad groups
2. Pull every ad with creative text and performance metrics
3. Rank headlines by CTR and conversion rate contribution
4. Identify stale ads (unchanged for 90+ days with declining performance)
5. Compare creative performance across ad groups and campaigns
6. Check ad strength ratings and pinning configurations
7. Look for messaging gaps in responsive search ad asset coverage

## Output

**Creative Audit Summary:**
- Total ads audited across campaigns and ad groups
- Average ad strength distribution
- Number of stale ads needing refresh
- Ad groups running with fewer than the recommended number of ads

**Top Performing Creative:**
- Best headlines by CTR and conversion rate
- Best descriptions by engagement metrics
- Winning combinations and patterns

**Underperforming Creative:**
- Ads with below-average CTR or conversion rates
- Headlines dragging down responsive search ad performance
- Ad groups with insufficient ad variety

**Recommendations:**
- Specific headlines and descriptions to pause
- New creative angles to test based on top performers
- Ad groups that need additional ad variants
- Pinning changes to improve responsive search ad flexibility
