Negative keywords are one of the simplest and most effective Google Ads tactics, yet they are often ignored. They stop your ads showing for irrelevant searches, which protects your budget, improves conversion rate, and usually improves lead quality. For UK service businesses, negative keywords can be the difference between profitable PPC and wasted spend.
Start with the obvious negatives based on intent. If you are selling a service, you probably want to exclude searches like jobs, salary, training, course, apprenticeship, free, DIY, and how to. If you are positioned as premium, you may also want to exclude cheap, lowest price, and bargain. These searches can generate clicks, but they rarely generate the right enquiries.
Then review your search terms report every week. Even with careful targeting, Google will match your ads to searches you did not expect, especially if you use broad match keywords or run Performance Max. Weekly negative keyword reviews are basic campaign hygiene. You will almost always find irrelevant terms that are quietly draining budget.
Negative keywords are not just about saving money. They improve your data. When you filter out poor intent traffic, a higher percentage of clicks turn into conversions. That tells Google your ads are relevant, which can improve performance over time and reduce cost per lead.
If you want better PPC results quickly, build a negative keyword list, review search terms weekly, and keep tightening. It is one of the highest impact habits in Google Ads management.
