Search Terms, Negatives, and Match Types: How to Cut Waste
One of the biggest advantages of Google Search campaigns is that you can inspect real user intent through search terms. A lot of waste does not come from bad ad copy. It comes from buying queries you never intended to pay for and failing to block them in time.
What this lesson solves
Core takeaway
Match types define how wide your query coverage can be. Negative keywords define what intent you want to reject. The search terms report shows what Google actually bought. You need all three together.
What broad, phrase, and exact each really mean
The search terms report is a top-priority optimization surface
Keywords describe what you broadly want to buy. Search terms show what the system actually bought. That means the search terms report is where you decide what to keep, what to block, and what deserves its own tighter management path. If you never review search terms, you are giving up a large share of what makes Search campaigns controllable.
Negative keywords are not about quantity. They are about precision.
Common mistakes
- Adding every non-converting term as a negative without context and accidentally blocking future useful demand.
- Using negatives too aggressively and choking volume.
- Ignoring negatives completely and letting budget leak into free, job, tutorial, accessory, or low-intent queries.
A more practical negative keyword logic
Prioritize these first
- Queries that are clearly unrelated to the business
- Low-commercial-intent queries that keep spending
- Recurring terms that consistently reduce quality without supporting your actual offer
When a search term deserves its own management path
If a search term repeatedly produces strong clicks and conversions, or it becomes important enough to deserve dedicated messaging and cost control, do not keep it buried in a broad keyword bucket. Breaking it out gives you tighter control over budget, bids, copy, and page fit.
Negative keywords also need layers
Some negatives are account-wide because they are clearly irrelevant everywhere, such as job, free, or tutorial intent. Others only belong at the campaign or ad-group level because the same term may be wrong in one context and useful in another. Without that distinction, one negative can solve a problem in one place while damaging demand somewhere else.
Execution checklist
Confirm before moving on
- You know that keywords are not the same as actual search terms
- You understand that broad, phrase, and exact are relative controls, not absolute guarantees
- You review the search terms report on a recurring basis
- Your negative keyword logic is focused on removing wrong intent, not collecting huge lists
Community field notes
What shows up repeatedly in practice
- There is constant debate around broad match, but the bigger determinant of success is usually conversion quality, negative discipline, and how seriously search terms are reviewed.
- Another common misunderstanding is treating exact match as literal exactness, then assuming the platform is broken when close variants appear.
- Experienced advertisers focus on which queries deserve more control, which should be blocked, and which should be split into tighter management.
