What is a negative keyword?
A negative keyword tells a search advertising campaign when a search should be excluded. Think of a decorating company that wants enquiries for paid work but keeps appearing when people look for decorating jobs. The words overlap. The intention doesn’t.
That distinction matters when you’re paying for attention. A busy campaign can produce plenty of clicks while giving the business very little it can use. The starting point is a clear brief: what you sell, where you work and what a suitable enquiry looks like.
Read the intention behind the words
Imagine a fictional business, Northridge Decorating, which paints homes and has no vacancies. Someone searching for a local decorator may be a good prospect. Someone searching for decorator apprenticeships is looking for a different relationship with the business.
We’d judge those searches against the actual offer before deciding what to exclude. A phrase that makes sense for one firm could be valuable for another. A training provider, for instance, might actively want the apprenticeship enquiry.

The match type changes the boundary
For Search campaigns, negative broad match excludes a search containing all the negative terms, in any order. Negative phrase match requires the terms in the same order. Negative exact match applies to that exact search without extra words.
A simple boundary can have a surprisingly large reach. Before excluding a phrase, read several searches it would affect and check that you’re comfortable losing those opportunities.

Illustration using the negative keyword “decorating jobs”.
- Broad
- Can exclude “jobs in decorating”.
- Phrase
- Can exclude “local decorating jobs”.
- Exact
- Excludes “decorating jobs” itself.
These illustrate the word and order rules, rather than predicting the outcome of an individual live auction.
A copied list can shut out useful enquiries
It’s tempting to paste in a huge list and feel that the account is now tidy. That can create problems. An interiors business might exclude “free” to avoid requests for free design work, then discover it has also shut out people asking about a free initial consultation that it genuinely offers.
The judgement is commercial. If a search describes an audience you serve, a service you provide or an agreed first step, it deserves a closer look before it goes on an exclusion list. A lower click count alone won’t tell you whether the change was sensible.
Ask to see the searches behind the clicks
The search terms report shows queries that triggered your ads, subject to reporting and privacy limits. Google notes that some low-activity queries are omitted, so the report is a useful view rather than a complete transcript of every search.
Look at the enquiry as well as the query. Did the person want a service you offer? Could you serve their location? Did the landing page explain the scope clearly enough? Keeping a short record of why a term was excluded makes later reviews much easier.
Some mismatches belong on the page rather than on a keyword list. If a business serves commercial projects, a landing page full of domestic examples is likely to leave the wrong impression even when the search itself is relevant.
Revisit exclusions when the business changes
New services, a wider service area or a recruitment campaign can turn yesterday’s unwanted enquiry into something useful. Treat exclusions as part of the campaign brief and review them when that brief changes.
Negative keywords also behave differently from positive keywords. Google says they don’t expand to close variants in the same way; synonyms and singular or plural forms can need separate consideration.
A clearer brief makes a better campaign
At Pointed, we agree the audience, offer and useful next step before building campaign creative or a landing page. That gives decisions about exclusions something concrete to refer to.
We can help connect the advert with a page that explains your business properly, with scope and price agreed before paid work starts. If you’re reviewing a campaign, bring the searches and a few real enquiries. They’re a much better conversation starter than a screenshot of the click total.
