Broad match vs exact match: which and when?
Broad match wins for discovery and reach under strong signal and negatives. Exact match wins for control and precision on proven queries. Combine them, with broad discovering and exact controlling.
Broad match casts wide and, paired with Smart Bidding and strong negatives, works as a discovery engine, while exact match targets proven queries with precision and control. Modern accounts often combine them: broad for discovery under a reliable conversion signal, exact for control on proven converters. The choice depends on your conversion data and negative-keyword discipline.

- You have a reliable conversion signal for Smart Bidding
- You want to discover new converting queries
- You maintain disciplined negative-keyword lists
- You want maximum reach for demand capture
- Your account has enough conversion volume to guide broad
- You want tight control over exactly which queries you serve
- Your conversion signal is thin or unreliable
- You are protecting proven, high-value converters
- Waste control is the priority
- You want predictable, precise targeting
Broad match without a reliable conversion signal and disciplined negatives can bleed spend on irrelevant queries, making it expensive despite its reach, while exact match limits waste but can miss valuable long-tail variations. The cost outcome depends less on the match type itself than on the conversion signal guiding broad and the negative-keyword discipline containing it. Judge each on cost per conversion, and remember that broad match is only as safe as the signal and negatives behind it.
This is not either-or but a structure decision. The modern approach uses broad match as a discovery engine feeding proven converters into exact-match campaigns, with strong negatives throughout. Moving fully to broad without a reliable signal and negatives is risky, and relying only on exact misses discovery. Combine them deliberately, and let the search-term report move terms from broad discovery into exact control.
