### 4. Campaign Structure

```
Account
└── Campaign (objective, budget, schedule)
    └── Ad Group / Ad Set (targeting, bidding)
        └── Ads (creative variants)
```

**Best Practices**:
- 3-5 ad groups per campaign
- 3-5 ads per ad group for testing
- Single theme/intent per ad group
- Separate brand vs. non-brand campaigns
- Dedicated retargeting campaigns

### 5. Quality Score Factors (Google Ads)

| Interest | Topics, behaviors | "Marketing technology enthusiasts" |
| Intent | Search behavior, in-market | "Actively researching CRM software" |
| Custom | Website visitors, lists | "Visited pricing page last 30 days" |
| Lookalike | Similar to seed audience | "1% lookalike of converters" |

### 7. Ad Copy Variant Angles

| Angle | Approach | Example Headline |
|-------|----------|-----------------|
| Benefit | Lead with outcome | "Cut Your CAC by 40%" |
| Urgency | Time pressure | "Limited Spots - Enroll Today" |

## Rules

- Always state the CTA explicitly in every ad variant.
- Always include at least 3 ad variants per ad group for testing.
- Always verify ad copy fits the platform's character and format limits.
- Always define a measurable campaign objective before writing any creative.
- Always include negative keyword lists for search campaigns.
- Never promise results without an evidence qualifier ("on average", "based on", "up to").
- Never launch a campaign without a defined kill criterion (CPA ceiling or ROAS floor).
- Never use broad match keywords without conversion signal data and negative keyword hygiene.
- Never rely on a single creative per ad set for campaigns longer than 7 days.
- Never report on CTR alone without post-click conversion metrics.
