Negative keywords for Shopping campaigns
How to steer keyword-free Shopping traffic with negative keywords, mining the search terms report, cutting waste, and using negatives plus campaign priority to route queries to the right campaign.
Shopping has no positive keywords, but it does have negative ones, and they're your main steering wheel. Negatives stop your products showing for searches that don't convert, and combined with campaign priority they route each query to the campaign you want serving it. Mine the search terms report, cut the waste, then use negatives to sculpt what's left.
Negatives are the steering wheel Shopping gives you
Because Shopping has no positive keywords, merchants sometimes assume they have no query control at all. Not so: you control queries in two ways: what your titles make you eligible for (covered in titles and query matching), and what your negatives exclude. Titles open lanes; negatives close them. Together they sculpt the traffic your products serve against.
The mistake is treating negatives as a cleanup afterthought. In a well-run Shopping account they're a primary steering tool, mined continuously from the one report that shows real shopper queries.
Where waste comes from
Most wasted Shopping spend falls into a few recognisable buckets:
| Waste type | Example | Better fix |
|---|---|---|
| Wrong intent | "how to clean waxed jacket" | Negative: informational, won't buy |
| Wrong product matched | "kids boots" hitting an adult listing | Fix the title first, then negative |
| Incompatible | "iPhone case" on an Android accessory | Negative + tighter attributes |
| Too broad / undifferentiated | bare "boots" on a niche product | Tighten title, then negative the strays |
| Competitor / off-brand | rival brand names | Negative if they don't convert for you |
Notice how often the real fix is upstream in the feed. A negative treats the symptom; a precise title removes the eligibility that caused it. Use both, but reach for the title fix when the wrong product matched.
Deep dive Negatives plus priority to route traffic between campaigns
Negatives do more than cut waste: paired with campaign priority, they route queries to the campaign you want serving them. This is the classic tiered Standard Shopping structure, and negatives are the mechanism that makes it work.
Google always serves the higher-priority campaign first for a matching product. So you build tiers and use negatives as gates:
- High priority: Generic/broad campaign. Serves first. Add negatives for your high-value and brand terms here. Because the valuable terms are blocked, generic traffic falls through to this campaign at a low bid.
- Medium priority: Category campaign. Add negatives for brand terms. Catches mid-intent queries the high-priority campaign blocked.
- Low priority: Brand/high-intent campaign. No negatives. Serves last, so it only ever gets the queries the higher tiers pushed down to it (your most valuable searches) where you bid up.
The counter-intuitive part: traffic flows from high priority down, and negatives are what push each query to the tier you want. A brand search hits the high-priority campaign, is blocked by its negatives, and cascades down to the low-priority brand campaign where you're willing to pay more. Without the negatives, every query would serve from the high-priority campaign at the wrong bid.
Campaign priority settings covers the full tiered structure. One hard limit: priority only arbitrates between Standard Shopping campaigns. PMax outranks all of them for the same product, so if PMax is in play, the only reliable separation is product-level, not priority-level: see Standard Shopping vs PMax.
A maintainable negatives workflow
- Mine monthly. The search terms report is only useful if you actually read it. Put a recurring slot in the calendar.
- Block on evidence, not hunches. Add negatives from terms with real spend and no conversions, not from guesses about what shoppers might type.
- Match type on purpose. Exact negative for a single bad query; phrase negative for a family (e.g. phrase "repair" catches "boot repair", "leather repair"). Broad match negatives are blunt: use with care.
- Centralise the universals. A shared negative list (free, cheap, DIY, used, wholesale, job, salary) applied account-wide saves you maintaining the same blocks per campaign.
- Check you haven't over-blocked. After adding negatives, confirm converting variants still serve. A phrase negative can catch more than you intended.
Negatives and titles are two ends of the same job: deciding which searches your products compete for. Keep both in the loop and your spend follows shopper intent instead of chasing it.
Step by step
- Pull the search terms report. In your Standard Shopping campaign, open Insights → Search terms. Look at the last 30–90 days. This is the only place Shopping tells you the actual queries that triggered your products, it's the raw material for everything that follows.
- Tag each term as convert, neutral, or waste. Sort by cost and by conversions. Terms with meaningful spend and no conversions are waste candidates. Terms that convert are ones to protect. Neutral terms you leave alone for now.
- Add waste terms as negatives. Add the clear waste terms as negative keywords. Use phrase or exact match deliberately, exact blocks one query, phrase blocks a family. Start narrow to avoid blocking converting variants.
- Separate 'wrong product' from 'wrong intent'. If a term is wasteful because the wrong product matched it, the real fix is the title, not just a negative, tighten the title so it stops matching that lane. Use negatives for genuine wrong-intent traffic (informational, incompatible, competitor-specific).
- Use a shared negative list for account-wide blocks. Put universally irrelevant terms (free, DIY, repair, used, job vacancy) in a shared negative keyword list applied across campaigns, so you maintain them in one place.
- Re-mine on a schedule. New queries surface constantly. Review the search terms report at least monthly; a term that was neutral last month may now be burning budget.
Frequently asked questions
Can I add negative keywords to Performance Max?
Only account-level negatives, and query control is limited, PMax gives you search category insights, not the full term report. This is the biggest reason to keep a Standard Shopping campaign in the mix when query control matters. See Standard Shopping vs PMax.
Should I block a wasteful term with a negative or fix the title?
Both have a place. If the wrong product matched, tighten the title so it stops being eligible for that query, that's the root cause. Use a negative when the intent itself is wrong (informational searches, incompatible use, competitor names) regardless of your title.
Won't aggressive negatives shrink my volume?
Only the volume that wasn't converting. Start narrow, add negatives from proven-waste terms rather than guesses, and watch conversions, you're trimming spend, not reach.
