An advertising account can look entirely healthy from the top. Impressions are up, clicks are steady, cost per click is where it was last quarter, and the account has not thrown a single warning. Then the phone does not ring any more than it did before, and nobody can say why.
The answer is almost always one report down. The dashboard shows you what you bought. It does not show you what you got, and the gap between those two things is where most of the money in a small advertising account quietly goes.
Keywords are what you bid on. Search terms are what you paid for.
A keyword is an instruction: show my ad to people looking for something like this. A search term is what a real person actually typed. Google decides which of those typed phrases are close enough to your instruction to count, and it decides generously, because a broader interpretation sells more clicks.
So you bid on emergency plumber and pay for plumber salary, plumbing courses near me, how to fix a leaking tap yourself, and the name of a competitor three towns over. Every one of those was a click, every one cost the same as a real one, and none of them will ever become a customer. The keyword list looks tidy the whole time.
The report that shows you the difference is the search terms report, and in most accounts it is two clicks from the front page — open the campaign, open Insights and reports, choose Search terms. Set the date range to the last ninety days, sort by cost descending, and read the first three screens. This is the single most useful half hour available to anybody paying for clicks.
What the leak usually looks like
The waste is rarely exotic. In local accounts it falls into the same handful of buckets nearly every time.
- Job seekers. Anything containing salary, jobs, hiring, apprentice, career or training. These are often among the highest-volume terms in a trade account and they convert at zero.
- Do-it-yourself research. How to, DIY, tutorial, diagram, step by step. The person is explicitly telling you they are not hiring anyone.
- Price shopping with no intent. Free, cheap, cheapest, second hand, used. Worth deciding on deliberately rather than by default — some businesses genuinely want the value shopper, most do not.
- The wrong service entirely. A landscaping account paying for tree removal it does not do, a practice paying for a procedure it refers out. The service is adjacent, the click is worthless.
- The wrong geography. Terms carrying a city, state or country you do not serve. Location targeting does not stop these, because targeting is about where the searcher is, not what they typed.
- Other companies' names. Sometimes worth bidding on deliberately; almost never worth paying for accidentally, and easy to miss because the volume is low while the clicks are expensive.
Negative keywords are the actual work
A negative keyword is the opposite instruction: whatever else happens, do not show my ad for this. It is the only lever that stops a leak permanently, and building the list is most of what account management actually consists of, month after month, indefinitely.
Do it in two layers. Keep a shared list of terms that can never apply to your business — the job seekers, the study material, the services you have never offered — and apply it to every campaign in the account, including the ones you launch next year. Then keep a per-campaign list for the things that are only wrong in context, so the ad group selling one service stops absorbing searches meant for another.
Add terms as phrases rather than single words wherever the single word would be too blunt. Excluding free costs you free estimate, which is a phrase your best customers type. Excluding free download does not.
Match types decide how wide the door is
Broad match takes your keyword as a suggestion about topic. It will find volume you would never have thought to bid on, and it will also find the wrong crowd faster than any other setting in the account. It is not a mistake, but running it without reading the search terms report weekly is.
Phrase match requires the meaning of your phrase to be present. Exact match requires something close to the phrase itself. A sensible pattern for a local account with a modest budget is to put the money on phrase and exact, run one small broad-match campaign as a discovery exercise, and promote anything it finds that converts into the tighter campaigns. That is a decision about where the money goes, which is the same question we worked through in work backwards from the jobs you want to the ad budget you need.
Nobody ever found the waste by looking at the keyword list. The keyword list is what you intended. The search terms report is what happened.
How often to check, and what to expect
Weekly for the first month of any new campaign, then monthly once the negative list has matured. New terms appear constantly because the way people phrase things shifts with the season, the weather and whatever a competitor has just started advertising.
Expect the first pass to be the dramatic one. It is common for a neglected local account to be spending a meaningful share of its budget on terms the owner would reject on sight, and reclaiming that is not a clever optimization — it is simply stopping the payment. The second month is quieter, and the discipline is what keeps it that way.
One caution: a click you excluded is only saved if the traffic you keep goes somewhere that works. Cutting waste while sending the good clicks to a slow page or an overlong form just moves the leak downstream, which is why the audit in your contact form is asking for too much belongs in the same afternoon.
If you would rather someone else read the report every week, that is a standing part of how we run paid advertising. Bring us an account you suspect is leaking and ask for a proposal — the search terms report is the first thing we open.
Frequently asked questions
- Where is the search terms report in Google Ads?
- Open a campaign or ad group, go to Insights and reports, then Search terms. You can also reach it from the Keywords section. Set a ninety-day window and sort by cost so the expensive mistakes surface first rather than the frequent cheap ones.
- How many negative keywords should an account have?
- There is no target number. A healthy local account usually accumulates somewhere between fifty and several hundred over its first year, most of them added a few at a time. What matters is that the list grows every month rather than being built once and abandoned.
- Can I just turn off broad match and be done with it?
- You will waste less immediately and you will also stop discovering phrases you never thought to target. A better setup is tight match types carrying the budget, with a small broad-match campaign kept deliberately as a research tool and reviewed often.
- Does any of this apply to ads on social platforms?
- Not directly — those are targeted by audience rather than by typed query, so there is no equivalent report. The parallel discipline there is checking placements and audience overlap, and the principle holds: look at what you actually bought, not at what you asked for.
