Quick decision guide for choosing structure type in references/decision-trees.md.

2026 Campaign Type Reference

Type	Purpose	Key Notes
Search	Text ads on Google Search	AI Max subtype (2026) for broad query coverage
Performance Max	All-channel automation	Negative keywords (v20+), search terms (v21+), network breakdown (v22+)
Demand Gen	Visual prospecting (YouTube, Discover, Gmail)	Replaced Discovery (Aug 2023), supports TargetCPC (v22+)
Display	Banner/image ads on GDN
Shopping	Product listing ads (feed-based)
Video	YouTube video campaigns
App	App install/engagement

Removed: Discovery (→ Demand Gen), Similar Audiences (→ Optimized Targeting).

Use to audit campaign types, identify consolidation candidates (<30 conv/month), and spot legacy structures.

Modern Structure Principles

1. Consolidation over fragmentation: Fewer campaigns with more conversions = faster Smart Bidding learning
2. Machine learning first: Smart Bidding + broad match, not manual bids + exact match
3. Theme-based ad groups (STAG): Same-intent keywords grouped (10-20 per group), replacing SKAGs
4. Budget = business constraint: Separate campaigns only for different budgets, geos, business units, or performance targets

Recommended Account Architectures

E-Commerce

Campaign	Budget %	Bidding	Purpose
Brand Search	10-15%	Max Conv or tCPA	Capture branded intent
Performance Max	40-50%	Max Conv Value + tROAS	Full-funnel automation
Non-Brand Search	30-40%	tCPA or tROAS	High-intent traffic
Demand Gen	5-10%	tCPA or tCPC (v22+)	Prospecting, visual products
Display Remarketing	5-10%	tCPA	Re-engage visitors

Lead Gen

Campaign	Budget %	Purpose
Brand Search	10-15%	Low CPA, high conversion rate
High-Intent Non-Brand	50-60%	Qualified leads ([service] + action terms)
Consideration/Research	20-25%	Top-funnel leads ([service] + question terms)
Performance Max (optional)	10-15%	Broader reach

Ad Group Best Practices (STAG)

• 10-20 keywords per ad group, all same intent/theme
• Same landing page, 2-3 RSAs per group
• Match type strategy: Broad 40-60% + Phrase 30-40% + Exact 10-20% (with Smart Bidding)
• Negatives are crucial with broad match: account-level list, campaign-level, weekly search term review

Campaign Consolidation

When to Consolidate

• <50 conversions per campaign per month (Smart Bidding "Learning Limited")
• Overlapping keywords across campaigns
• Same CPA/ROAS targets with no reason for separation
• Fragmented budgets across many small campaigns

Keep Separate When

• Different budget pools or business units
• Different geographic/language targets
• Significantly different performance targets (brand vs non-brand)
• Compliance/organizational requirements

Consolidation Process

Phase 1 (Week 1): Export data, identify candidates, map keyword overlap, plan new structure.

Phase 2 (Week 2): Build new consolidated campaigns, reorganize keywords, write RSAs, configure bid strategy.

Phase 3 (Week 3): Soft transition — reduce old budgets 50%, enable new with 50%, shift gradually over 7-14 days.

Phase 4 (Week 4+): Monitor Learning Phase, adjust targets, optimize negatives, review search terms.

Portfolio Bid Strategies

One bid strategy across multiple campaigns — useful when individual campaigns have too little data.

• Target CPA Portfolio: Multiple lead gen campaigns, same CPA target
• Target ROAS Portfolio: Multiple e-commerce campaigns, same margin target
• Maximize Conversions Portfolio: New/small campaigns needing aggregated data

SKAG to Modern Migration

SKAGs (Single Keyword Ad Groups) no longer work because Smart Bidding needs data volume, close variants make exact match imprecise, and broad match + Smart Bidding outperforms.

Migration steps:

1. Export all SKAGs, group keywords by theme/intent
2. Define new structure: 500 SKAGs → 30-50 themed ad groups in 3-5 campaigns
3. Consolidate ad copy: 2-3 RSAs per group using best performers as base
4. Gradual transition over 4 weeks (20% → 50% → 80% → 100% new structure)
5. Post-migration: monitor Learning Phase (2-4 weeks), expand with broad match gradually
