The best place to find negative keyword ideas in Google Ads is the Search terms report. It shows the searches that triggered your ads, so you can decide which queries represent irrelevant intent and which deserve a different fix.
Do not turn every search with zero conversions into a negative. A query can be relevant but have too little data, a long conversion lag, a weak landing page, or broken tracking. Negative keywords should remove unwanted demand—not merely demand that has not converted yet.
Where to find negative keyword ideas
In the current Google Ads interface:
- Open Campaigns.
- Open Insights and reports.
- Select Search terms.
- Set a date range that accounts for your conversion lag.
- Review all search terms, or select a smaller group of keywords or campaigns.
Google’s Search terms report instructions explain the same workflow and let you add selected rows directly as negative keywords. The report shows terms with a significant amount of activity, so it is valuable evidence but not a complete transcript of every search.
Start with the right columns
At minimum, review these fields together:
| Field | Question it answers |
|---|---|
| Search term | What did the person actually search? |
| Keyword and match type | Why was the query eligible? |
| Campaign and ad group | Where would an exclusion take effect? |
| Cost, clicks, and impressions | How much evidence or exposure is there? |
| Conversions and conversion value | Did the query produce a measured outcome? |
| Landing page or ad destination | Is the problem targeting, routing, or the page? |
The keyword is what you added. The search term is what the person typed. Negative keyword decisions should start with the search term, then use the campaign context to decide where an exclusion belongs.
Classify intent before performance
Use a small decision set instead of a vague “bad keyword” label.
| Classification | Example | Next action |
|---|---|---|
| Exclude | emergency plumber jobs for a plumbing-service campaign | Add a scoped negative |
| Investigate | cheap emergency plumber | Read the query and business context; do not assume it is irrelevant |
| Keep or target | emergency plumber near me | Leave eligible or consider it as a positive keyword |
| Fix destination | A service the business sells, but the ad sends to a generic page | Improve structure, page, or routing |
| Fix measurement | A relevant query with broken call or form tracking | Repair conversion tracking before judging it |
Strong exclusion signals often include employment, education, do-it-yourself, unsupported services, wrong locations, or a customer type the business cannot serve. “No conversion” is not an intent category.
A 30-minute workflow
1. Set the business rules first
Write down what the campaign does not offer:
- services or products the business does not sell;
- locations it cannot serve;
- customer types it does not accept;
- employment, training, or research intent that is not commercial;
- support requests that belong to an existing-customer channel; and
- brand or competitor policies that need separate review.
This prevents the report from becoming a purely statistical exercise. A low-volume search for a service you never offer can be a clear negative even without a large spend history. A high-cost search for a service you do offer may need a landing-page or sales-process fix instead.
2. Review obvious mismatches and high-impact rows
Start with clear intent mismatches, then sort by cost or clicks to find expensive patterns. Read nearby rows before acting. One query may be irrelevant while a very similar query is valuable.
For each candidate, finish this sentence:
This search should be excluded from this campaign because ______.
If the blank is “it has not converted,” keep investigating. If the blank identifies a concrete service, location, or intent mismatch, you have a defensible reason to consider a negative.
3. Choose the smallest useful negative
You can add the full query as an exact negative, extract a repeated phrase, or use a broader combination of words. Choose based on what the evidence supports.
- Use exact for one known-bad query when adjacent searches may be useful.
- Use phrase when a sequence of words consistently represents unwanted intent.
- Use broad only when every word in the combination is unwanted together, regardless of order.
See Google Ads negative keyword match types for examples. Negative match types do not expand like positive keyword match types, so do not assume one negative covers synonyms, singulars, plurals, or every close variant.
4. Apply the negative from the report
Select the relevant search terms and choose Add as negative keyword. Google lets you add the negative to an ad group, a campaign, an existing negative keyword list, or a new list.
For Search campaigns, Google adds rows from this workflow as negative exact match by default. Add quotes for phrase match or leave the term unquoted for broad match; use brackets for exact match when entering or editing the keyword manually. Check the destination before saving.
5. Verify scope and monitor the next window
Ask two final questions:
- Is this intent unwanted everywhere, or only in this campaign?
- What valuable searches could contain the same word or phrase?
After the change, check whether the unwanted pattern decreases and whether qualified impressions, conversions, and conversion value remain healthy. Lower spend alone is not proof of improvement.
Find ideas outside the report
The Search terms report is the primary source because it reflects actual demand, but it is not the only input. Ask the business owner, sales team, and customer-support team for:
- services and locations that are routinely declined;
- recurring employment or education searches;
- common wrong-customer or supplier requests;
- product names or service terms that sound similar but are not offered; and
- new exclusions introduced by a change in inventory, geography, or positioning.
Use generic negative-keyword lists as prompts, not as something to paste into every account. Words such as free, cheap, used, and jobs can be useful or harmful depending on the offer.
Common mistakes
- Blocking every non-converter: This removes potentially valuable learning and demand.
- Ignoring campaign context: A service can be wrong for one campaign and right for another.
- Using the report’s match type as the negative’s match type: The report describes the positive keyword relationship.
- Adding a broad one-word negative: Ambiguous words can block a large amount of qualified traffic.
- Forgetting variants: A negative does not automatically express every synonym or singular/plural form.
- Never checking tracking: Bad conversion data makes good searches look unprofitable.

Use a reviewable workflow
LeadUp’s Google Ads negative keyword tool reviews available Search and Performance Max search terms alongside campaign structure, targeting, active keywords, and existing negatives. It explains why a query was flagged and prepares a recommendation that you can edit and approve before applying.
That division of labor matters: automate collection and prioritization, but keep the business decision reviewable.
Bottom line
Find negative keywords in actual search-term data, classify intent before looking at short-term performance, choose the narrowest safe match type, and apply it at the smallest correct scope. A short list built from real queries will usually outperform a large generic list that no one understands or maintains.
