When you run Google Ads, you choose the keywords you want to appear for. But Google also matches your ads to variations and related searches, and some of those searches have nothing to do with your business. Every click on an irrelevant search costs money and brings no customer. Negative keywords are how you tell Google what not to show your ads for.
They are one of the highest-value habits in paid search because they work directly on waste. A few minutes of review each week can protect your budget and improve your lead quality.
What is a negative keyword?
A negative keyword is a word or phrase that prevents your ad from showing when a search includes it. If you sell premium kitchen renovations and add 'cheap' as a negative keyword, your ads will not appear for searches that contain that word.
Why they matter
- They reduce wasted spend on irrelevant clicks.
- They improve click-through rate and relevance, which helps your account quality.
- They raise lead quality by filtering out people who are not looking for what you sell.
- They help small budgets go further.
- They make your reports cleaner, so you can see what truly works.
Where to find negative keyword ideas
The search terms report
This is the most important source. It shows the actual searches that triggered your ads. Open it regularly, sort by cost or clicks and read each query honestly. If a term could never lead to a sale, add it as a negative.
Your own customer questions
Look at the questions people ask on WhatsApp and the phone. If many enquiries are about something you do not offer, such as jobs, free services or a different product, add related negatives.
Common categories to consider
- Job seekers: 'jobs', 'vacancy', 'hiring', 'salary', 'career'.
- Free seekers: 'free', 'free download', 'no cost' (only if you never offer free options).
- Education: 'course', 'training', 'tutorial', 'how to' (if you are not selling education).
- DIY: 'DIY', 'make your own' (if you sell a service).
- Wrong product types: variations that sound similar but are not what you sell.
- Competitor or brand names where you decide not to target them.
- Wrong locations: cities or emirates you do not serve.
Match types for negatives
Negative keywords also have match types, and they behave differently from positive keyword match types. Understanding them prevents both under-blocking and over-blocking.
- Broad match negative: blocks the ad if the search contains all the words in any order. It does not automatically block close variants or synonyms.
- Phrase match negative: blocks the ad if the search contains the words in that exact order, possibly with other words around.
- Exact match negative: blocks the ad only when the search is exactly that phrase.
Because negatives do not automatically include plurals, misspellings or synonyms the way positive keywords can, you may need to add several variations. Check Google's current documentation for the latest behaviour.
Campaign level, ad group level and lists
- Campaign-level negatives apply to the entire campaign. Use them for words that are never relevant.
- Ad group negatives apply to a single ad group. Use them to separate similar groups so that they do not compete.
- Negative keyword lists let you reuse a set of negatives across several campaigns.
- Account-level negatives, where available, apply across the whole account.
A common technique is to use negatives to route searches to the best ad group. If you have one group for 'emergency plumber' and one for 'plumber near me', add the first phrase as a negative in the second group so that the right ad appears for the right search.
A weekly routine that takes twenty minutes
- Open the search terms report for the last seven to fourteen days.
- Sort by cost, then by clicks with no conversions.
- Mark each irrelevant term and decide the right match type.
- Add the negatives at the right level.
- Note what you added and why, in a simple log.
- Check again after a few days to confirm unwanted terms stopped appearing.
In a new account, review the report even more often in the first weeks, because that is when most waste appears.
Arabic and bilingual accounts
If you advertise in both Arabic and English, review the search terms in both languages. Arabic queries can include spelling variations, dialect words and transliterated English words. Build negative lists for Arabic separately, and ask a native speaker to review them so that you do not block valuable searches by mistake.
Mistakes to avoid
- Adding a negative that blocks your own best keyword.
- Using a broad match negative that is too general.
- Forgetting that negatives do not catch every variation automatically.
- Never reviewing the search terms report.
- Copying someone else's negative list without checking it against your business.
- Blocking so many terms that your campaign cannot get impressions.
How to check that your negatives are working
- Your cost per conversion should improve over time if waste is removed.
- Click-through rate often rises as irrelevant impressions disappear.
- The search terms report should show cleaner, more relevant queries.
- Lead quality, not just quantity, should improve.
Frequently asked questions
How many negative keywords should I have?
There is no fixed number. Add as many as your search terms report justifies. Quality matters more than volume.
Will negatives reduce my traffic?
They reduce irrelevant traffic, which is the goal. If your impressions drop sharply, you may have blocked something valuable, so review recent additions.
Can I remove a negative later?
Yes. Review negatives periodically, because your offer and the market can change.
