Negative keywords assist a Search campaign in several ways:

1. Limiting Unwanted Traffic: Negative keywords prevent ads from being delivered for searches that might otherwise qualify but most likely don't match the intent of the search. This means that your ads will only appear for searches that are relevant to your products or services, reducing the likelihood of attracting uninterested users.

2. Cost Efficiency: By preventing your ads from appearing in irrelevant searches, negative keywords can help you save money on wasted clicks. This makes your campaign more cost-effective.

3. Improved Click-Through Rate (CTR): Since your ads are more targeted and relevant to the user's search, they are more likely to click on your ad. This can improve your ad's click-through rate (CTR), which can improve your Quality Score and lower your cost per click (CPC).

4. Better Conversion Rates: As your ads are more relevant to the user's search, they are more likely to be interested in your product or service and therefore more likely to convert.

Please note that negative keywords do not give marketers insight into what other searches customers are using to arrive at their business, nor do they limit the terms competitors can bid on at auction. They also do not directly affect customer reviews.
