2. What Are Negative Keywords?
Definition of Negative Keywords
Negative keywords are specific terms or phrases that prevent your ads from being shown for irrelevant search queries. They act as filters, ensuring your ads are displayed to the right audience.
Example:
If you’re running ads for luxury kitchen remodeling, you might exclude terms like:
- “Cheap kitchen remodel”
- “DIY kitchen upgrade”
- “Free kitchen renovation”
Why Are Negative Keywords Important?
- Prevent Irrelevant Clicks: Avoid wasting your budget on searches that won’t convert.
- Improve Ad Relevance: Align your ads with high-intent searches.
- Lower CPC (Cost-Per-Click): Prevent unnecessary spending on non-qualified traffic.
- Boost Conversion Rates: Target users with genuine interest in your offerings.
