How to work the search terms report and cut wasted spend
Sort the search terms report by cost, read the rows that spent money and returned nothing, and turn them into negatives. Here is the weekly routine.
Open the search terms report, sort by cost, and read every query that spent money and returned no conversion. Run that once a week and you stop most of the budget leak in a paid search account. The rest of this post is how to do it without cutting the traffic you actually want.
Your keyword list is what you asked Google for. The search terms report is what you got. The money sits in the gap.
What the search terms report actually shows you
Less than everything. Google filters the report by a privacy threshold and describes it as reporting only on terms that "have seen sufficient search volume across all Google searches." The exact number has never been published, and the hidden share moves around by account and by campaign type.
So start with a reconciliation. Take total campaign cost for the period, then sum the cost column across the visible search terms. The difference is your blind spot. If it's a few percent, the report is a good map and you can work it directly. If a third of your spend lands in rows you can't read, tighten your match types and your keyword themes first, because the report alone won't find that waste for you.
The weekly review, in twenty minutes
The routine is short enough to keep, which is the only reason it works. Once a week for a new campaign, every two weeks once spend and results settle.
- Set the date range to the last 7 or 14 days. Anything longer and you're re-reading terms you already handled.
- Sort by cost, descending. Not by impressions. Impressions are free; clicks are the thing you paid for.
- Read down until the cost per row stops mattering. In a campaign spending 3,000 a month, that's usually the first 40 to 60 rows.
- Mark three buckets as you go: wrong intent, wrong product, wrong person. Job seekers, students, DIY researchers, and competitor-brand tyre-kickers each belong to a different bucket and each gets a different fix.
- Add the negatives, then look at what's left. The converting terms are the other half of the job.
Twenty minutes, every week, beats a four-hour audit every quarter. New queries arrive continuously, so a one-time purge starts decaying the day after you run it.
Where the negative goes, and at what match type
Two homes, and picking the wrong one is how good campaigns get strangled.
Account-level or shared lists hold the exclusions that are true everywhere you advertise: jobs, salary, careers, free download, wikipedia, torrent. Write this list once and attach it to everything.
Campaign-level negatives hold intent separation. If one campaign chases high-intent buying queries and another chases top-of-funnel research, each needs the other's terms excluded so they stop bidding against each other.
Then get the match type right. Google is explicit that negative keyword match types work differently from their positive counterparts and don't match to variants, including plurals and misspellings. A negative exact for "crm software" blocks that phrase alone. A negative phrase for "free" blocks every query containing the word. That second one is where teams get hurt: block "free" across a SaaS account and you've just killed "free trial," which is often the best-converting query you have.
Adding a term straight from the report applies it as negative exact by default. Leave it there unless you have a reason to widen it, and when you do widen it, search the term first to see what else it would catch.
Three ways teams cut too much
The first is the broad negative that swallows a converting query, the "free" case above. Before you add anything as phrase or broad, filter your own search terms report for that word and check what it would have blocked over the last 90 days.
The second is a negative added at account level to solve a single campaign's problem. It works today and quietly breaks the campaign you launch next quarter.
The third is treating the list as finished. Query patterns shift with seasons, product launches, and whatever the algorithm decides to test this month. The list is a habit, not a deliverable.
Then do something with the winners
The same report tells you what to build. Any term that converted more than once and isn't in your keyword list is a candidate for its own ad group with its own copy and its own landing page. Terms that convert at a cost well under your target tell you where to push budget, which is easier to judge if you already set a target CPA before launch.
The converting queries are also a content brief. A question people pay you to answer in paid search is a question worth ranking for organically, and the report gives you the phrasing in the searcher's own words. That is free research most teams throw away.
One caveat on judging any of this: a week of search terms is a maintenance signal, and it isn't enough data to decide whether the channel works. That verdict needs a proper test window and enough budget to reach it.
If you want help turning this into a paid programme that pays back, that's the kind of work we do.
