Negative keywords help a Google Ads campaign avoid searches that are clearly outside the advertiser’s offer. For a Malta business working with a limited local market, careful exclusions can make search traffic more relevant. Poorly chosen exclusions can do the opposite by blocking genuine prospects.
This guide explains how to build, review and govern negative keywords using evidence from the account. It is not a universal list to paste into every campaign. A term that is irrelevant to one business may describe a valuable customer need for another.
What is a negative keyword?
A negative keyword tells Google Ads not to show an eligible ad for searches that meet the negative match rule. Google supports negative broad, phrase and exact match for Search campaigns. These match types behave differently from positive keywords, so they should be reviewed before being applied.
Google’s official guidance notes that negative keywords do not match close variants or other expansions. Singular and plural versions, synonyms and related wording may therefore need separate consideration. Misspellings and casing are treated differently. Review Google’s negative-keyword documentation before choosing match types.
Why negative keywords matter for Malta campaigns
A local campaign can attract searches that look relevant at first but have the wrong purpose, location or commercial intent. A company selling a professional service may trigger searches from people looking for jobs, free templates, courses, definitions or do-it-yourself instructions. An ecommerce business may attract searches for products it does not stock, wholesale enquiries it cannot serve or delivery locations outside its coverage.
Negative keywords can help separate those searches, but geography alone should be controlled primarily through campaign location settings. Do not try to solve every targeting problem by excluding place names. Google Ads location options and actual user intent should be reviewed together.
Start with the search terms report
The search terms report shows queries that triggered ads and were reported by Google. It is the most useful starting point because it reflects actual campaign traffic rather than assumptions. Google specifically recommends using the report to identify terms related to the campaign but not to what the business sells. See Google’s search-terms workflow.
Review enough context before excluding a query. A term with no conversion may still be relevant if tracking is incomplete, volume is low or the buying journey is longer than the selected reporting window. Consider relevance first, then performance.
- Search term and the keyword or targeting that matched it.
- Campaign, ad group and landing page shown.
- Clicks, cost and recorded conversions.
- Whether the search represents a service the business offers.
- Whether the user’s location and language fit the campaign.
- Whether the term indicates research, purchase intent, employment or support.
- Whether the conversion action measures a genuine business outcome.
Not every query will appear in reporting. Decisions should therefore use the available search-term data alongside campaign structure, customer conversations and website analytics, without assuming the report contains every search.
Classify before excluding
A simple classification prevents hasty decisions. Place reviewed terms into one of four groups:
- Relevant now: the search matches the offer and should remain eligible.
- Relevant but misplaced: the search belongs in another campaign, ad group or landing page journey.
- Potentially relevant: the intent is unclear and needs more data or business input.
- Irrelevant: the search cannot reasonably become a suitable customer for the advertised offer.
Only the last group is an obvious candidate for exclusion. “Relevant but misplaced” may require campaign restructuring rather than a blanket negative. This is particularly important when different services share vocabulary.
Choose the correct negative match type
Negative exact match
Negative exact match blocks the precise search term in the same order without additional words. It is useful when one specific query is unsuitable but broader variations may still be valuable. Google states that searches containing extra words may remain eligible.
Negative phrase match
Negative phrase match blocks searches containing the full phrase in the same order, even when other words appear before or after it. It is appropriate when a phrase consistently signals the wrong intent, but it should be checked for valuable longer searches that also contain that phrase.
Negative broad match
Negative broad match is the default for negative keywords. A search is blocked when it contains all the negative keyword terms, even in a different order. The ad may still show when only some terms appear. Because this can affect a wider set of queries, review the language carefully before using it.
Google’s examples show that negative match types do not behave like their positive equivalents. Test each proposed exclusion against realistic searches your prospects might use.
Create useful negative-keyword themes
Do not begin with a giant generic list downloaded from the internet. Build themes that reflect the business and the campaign. Possible review categories include:
- Employment intent, such as vacancies, careers, salary, internship or apprenticeship, when the campaign is not recruiting.
- Free or do-it-yourself intent, when the business sells a managed professional service and does not provide the requested resource.
- Education intent, such as course, degree, tutorial or definition, when training is not offered.
- Unsupported products, services, customer types or geographic areas.
- Existing-customer support searches that should use a support channel rather than a sales landing page.
- Competitor or brand terms, but only after deciding whether the campaign intentionally targets or protects those searches.
- Research terms that clearly cannot lead to the campaign’s intended outcome.
These are prompts for investigation, not automatic exclusions. For example, “course” may be irrelevant to an agency campaign but essential to a training provider. “Free” could indicate poor intent for one offer while describing a legitimate free consultation for another.
Use campaign, list and account levels deliberately
An exclusion should be applied at the narrowest level that solves the problem without affecting valid campaigns.
- Ad-group negatives can separate closely related themes inside one campaign.
- Campaign negatives can block terms that are unsuitable for one campaign but valid elsewhere.
- Shared negative keyword lists can apply the same reviewed theme across several campaigns.
- Account-level negatives can apply across eligible Search and Shopping inventory and should be reserved for terms that are genuinely unsuitable everywhere.
Google allows campaign-level negative keyword lists to be shared across campaigns. Updating the list then affects every campaign using it. See Google’s negative-list guidance. This is efficient, but it also means an incorrect entry can have a wider impact.
Avoid conflicts with valuable keywords
Before adding a negative, check it against active keywords, search themes, brand terms, product names and landing-page language. Google warns that negatives overlapping regular keywords can prevent ads from showing. Review Google’s implementation guidance.
Pay particular attention when several campaigns target similar services. Cross-campaign negatives can help route a query to the intended campaign, but only when the structure and priority are documented. Otherwise, they can create gaps where no appropriate ad remains eligible.

A practical weekly review workflow
- Open the search terms report for a meaningful recent period.
- Filter or sort by cost, clicks and conversions to prioritise review.
- Read each term in the context of the matched campaign and landing page.
- Classify the term as relevant, misplaced, uncertain or irrelevant.
- Choose the narrowest suitable level and match type for any exclusion.
- Check for conflicts with active keywords and valuable longer searches.
- Record the reason, owner and date for material exclusions.
- Monitor search volume, conversions and lead quality after the change.
High-spend or rapidly changing campaigns may need more frequent review. Lower-volume campaigns still need periodic checks, but decisions should not be forced from too little evidence.
Measure lead quality, not only reduced spend
The purpose of negative keywords is not simply to make campaign spend fall. A successful change should improve the relevance of remaining traffic while preserving access to valuable demand. Review qualified enquiries, sales outcomes and conversion quality alongside cost and click metrics.
Accurate conversion tracking is essential. Use the Google Ads conversion-tracking checklist to confirm that calls, forms and other actions are recorded appropriately. If the landing page attracts the wrong enquiries, also review DCP’s landing-page checklist.
Common negative-keyword mistakes
- Pasting a generic industry list without reviewing each term.
- Using broad exclusions where exact or phrase match would be safer.
- Blocking research searches that contribute to a longer buying journey.
- Adding all poor-performing terms as negatives regardless of relevance.
- Using account-level negatives for campaign-specific problems.
- Ignoring singular, plural and synonymous wording where appropriate.
- Failing to review shared lists after services or campaigns change.
- Optimising around unreliable or incomplete conversion tracking.
- Letting an agency make major exclusions without a clear change record.
Questions to ask a Google Ads agency
- How often do you review search terms and who performs the review?
- How do you decide whether a term is irrelevant or simply underperforming?
- Which negative lists are shared across campaigns?
- Who approves account-level exclusions?
- How do you test for conflicts with valuable keywords and services?
- Will reports explain significant exclusions and their effect on lead quality?
- How will negative keywords be handed back if the agency relationship ends?
Account ownership and visibility matter because exclusions can materially change campaign reach. DCP’s Google Ads account-ownership checklist and agency onboarding checklist explain how to retain access and document responsibilities.
Make exclusions evidence-based
A strong negative-keyword process combines search-term evidence with a clear understanding of the offer, customer journey and campaign structure. It removes obviously unsuitable traffic without turning the account into a maze of exclusions that suppresses useful demand.
