Definition
Broad match allows ads to show on searches related to your keyword, not only exact matches. It increases reach but can reduce relevance.
Example
A keyword like project management software can match queries about project tools, templates, or comparisons.
How to use it
- Use broad match with strong negatives and clear conversion signals.
- Monitor search terms to avoid wasted spend on irrelevant queries.
- Pair with smart bidding only after conversion tracking is stable.
Common mistakes
- Turning on broad match without enough conversion volume.
- Ignoring match type performance differences by segment.
Why this matters
This term matters because it affects how you interpret performance and make budget decisions. If you use inconsistent definitions or windows, ROAS/CPA can look "better" while profit gets worse.
Practical checklist
- Write a 1-line definition for "Broad Match" that your team will use consistently.
- Keep the time window consistent (weekly/monthly/quarterly) when comparing trends.
- Segment results (channel/plan/cohort) before drawing big conclusions from blended averages.
- Sanity-check with a related calculator from the same category on MetricKit.
- Read the related guide (e.g., Paid ads bidding & budgeting hub: max CPC, target CPA, and break-even targets) for context and common pitfalls.
