Match Type Strategy by KPI: Complete Guide to Exact, Phrase, and Broad Optimization

Introduction

"Exact performs well but doesn't scale" "Broad expands reach but ACoS spirals" "Phrase's role is unclear" — match type management challenges are universal.

The solution: Exact = monetization core / Phrase = precise semi-discovery / Broad = discovery expansion. Align this trinity with KPIs (ACoS/ROAS, CTR, CVR, impression share) and systematize promotion/exclusion via weekly harvest loops (#4) for the fastest path to optimization.

Executive Summary (Conclusion First)

• Exact: Monetization core. Establishes foundation on high-intent queries.
• Phrase: Semi-discovery layer. Expands range while preserving word order.
• Broad: Discovery engine. Captures synonyms, variations, and related terms for "surface area" expansion.
• Allocation principle: Concentrate budget and bids on Exact; treat Phrase/Broad as "discovery/incubation budgets".
• Weekly operations: Apply #4's Promote/Hold/Exclude framework to promote to Exact, enforce cross-negatives to prevent cannibalization.
• Bidding/budget: Start with #27's target ACoS reverse formula, adjust ±10–15%/week based on performance.

Match Type Definitions (Amazon Standards)

Match Type	Match Concept	Example	Notes
Exact	Matches keywords in same order and close meaning (includes close variants)	olive oil 1l → "olive oil 1l", "olive oils 1 litre"	Most precise. Narrow reach but higher CVR tendency
Phrase	Preserves word order, allows additional words before/after	"extra virgin olive oil" → "best extra virgin olive oil 1l"	Expands reach while maintaining demand range
Broad	Flexible word order + related terms/variations included	olive oil → "healthy cooking oil", "spanish olive oils"	Widest reach. Maximum discovery power but noise included

Note: Negatives available as Negative Exact / Negative Phrase. Negative Broad doesn't exist, so constrain over-expansive Broad with Phrase negatives.

KPI × Match Type: Role Matrix

KPI Objective	Recommended Match	Rationale	Operational Tip
ACoS optimization/profitability	Exact	High CVR, precise bid control	Immediately add promoted terms to Exact, block in Auto/Broad with Exact negatives
New entry expansion (NTB proxy)	Phrase / Broad	Discover unknown long-tail	Apply Promote/Hold/Exclude thresholds via CTR/ACoS
Impression share improvement/placement	Phrase	Expand surface while preserving demand range	Position as semi-discovery at low bid/budget
Category dominance (competitor containment)	Exact + Phrase	Maximize exposure across brand/category axes	Separate branded/generic, coordinate with SB/SBV (#3)

---

Budget Allocation Templates by Growth Stage

Stage	Objective	Exact	Phrase	Broad	Notes
Launch (~30 days)	Establish sales foundation	60%	25%	15%	Exact focus for efficiency. Constrain discovery initially
Growth (~90 days)	Entry expansion	50%	30%	20%	Strengthen long-tail capture via Phrase/Broad
Profit Optimization (ongoing)	Maintain profitability	65–70%	20–25%	10–15%	Harvest winning terms into Exact consolidation

Note: Adjust by category/price point. High-ticket & niche → Exact-heavy; low-price & high-turnover → slightly stronger Phrase/Broad.

Promotion & Exclusion Rules (Weekly Harvest Loop)

Following #4's framework, reallocate from Search Term Report (STR) across Exact/Phrase/Broad.

Promote Guidelines

• To Exact: Past 14–30 days
  • Clicks ≥ 20 & Orders ≥ 2, OR
  • ACoS ≤ Target+5pp & Spend ≥ 5× Avg CPC
• To Phrase:
  • Clicks 10–19 & CTR ≥ Account Avg, but premature for Exact promotion

Exclude Guidelines

• Negative Exact (to Auto/Broad):
  • Clicks ≥ 25 & Orders = 0, OR ACoS ≥ Target+15pp
• Negative Phrase (noise suppression):
  • Impressions ≥ 1,500 & CTR ≤ 0.15% and other broad noise sources

Hold

• Prioritize creative/PDP improvements (#35, #36) or price/inventory sync (#32)

-- Example: Promotion/exclusion candidate extraction (BigQuery)
create or replace view v_matchtype_actions as
select
  query,
  sum(impressions) imps,
  sum(clicks) clicks,
  sum(orders) orders,
  safe_divide(sum(cost), nullif(sum(sales),0)) acos,
  avg(cpc) avg_cpc,
  case
    when (clicks >= 20 and orders >= 2)
      or (acos <= :target_acos + 0.05 and sum(cost) >= 5*avg_cpc)
    then 'PROMOTE_EXACT'
    when (clicks >= 25 and orders = 0) or (acos >= :target_acos + 0.15)
    then 'NEGATIVE_EXACT'
    when (imps >= 1500 and safe_divide(clicks, nullif(imps,0)) <= 0.0015)
    then 'NEGATIVE_PHRASE'
    else 'HOLD'
  end as action
from str_last_30d
group by query;

Bid/Budget Allocation and Cross-Negative Hierarchy

Bidding

• Initialize bids with #27: Target ACoS reverse formula.
• Weekly adjustments: ±10–15% based on performance (advance thresholds pre-events per #31).

Budget

• Heavy allocation to Exact; Phrase/Broad at low–medium levels for learning/discovery.
• Budget ratio guideline: Exact 1.0× / Phrase 0.6–0.8× / Broad 0.4–0.6× (within-category comparison).

Negative Hierarchy (Cannibalization Prevention)

• Add Exact negatives to Auto/Broad/Phrase for promoted terms.
• Constrain over-expansive Broad with Negative Phrase.
• Campaign separation: Exact core, Phrase semi-discovery, Broad discovery as separate campaigns for safety.

Related: Align top-level allocation with SP/SB/SD roles per #3.

---

Measurement Pitfalls: Broad Interpretation and TACoS Evaluation

• Broad's "related terms" definition is expansive: Avoid overreacting to short-term ACoS spikes; systematize via promotion/exclusion rules.
• View-through and NTB limited in SP: Combine with SB/SD performance for holistic TACoS evaluation (#41).
• Fix attribution window: Display permanently on dashboard (#42) to eliminate meeting "dialects".

---

Case Studies (2 Examples)

Case 1: Consumer Goods (High-Turnover)

• Design: Exact focus (65% allocation) + Phrase 25% + Broad 10%
• Operations: Weekly promotion/cross-negatives, expand via Phrase then harvest to Exact
• Results (6 weeks): ACoS -5.4pp, sales +19%, +34% new queries at same budget

Case 2: Gift Food (High Seasonality)

• Design: 3 weeks pre-event, increase Phrase/Broad → accelerate promotion
• Operations: Price/inventory × bid sync (#32) & SBV for top placements
• Results (8 weeks): CTR +17%, CVR +11%, TACoS -2.0pp

Lesson: Discover via Phrase/Broad, monetize via Exact. Early promotion + cross-negatives balance efficiency and scale.

FAQ

Q1. Is Broad dangerous? A. Not dangerous—"requires management". Constrain with Negative Phrase, harvest winning terms to Exact via promotion loop.

Q2. Is Phrase necessary? A. Yes. Captures longer-intent queries Exact can't reach, while maintaining safety via word-order preservation.

Q3. Should bids differ by match type? A. Yes. Typically Exact ≥ Phrase ≥ Broad. Higher for Exact, conservative for discovery budgets.

Q4. What if budget is limited? A. Exact-heavy is fine. As capacity increases, add Phrase first, then Broad at minimum discovery level.
