What is a reason to use negative keywords?

• A. To prevent showing for unrelated searches and improve efficiency.
• B. To increase impressions
• C. To lower quality score
• D. To automatically generate new keywords

Answer: (A)

Using negative keywords to prevent ads from showing for unrelated searches and improve efficiency. Negative keywords filter out terms you don’t want your ads to trigger for, so your budget is directed toward more relevant queries. This reduces wasted impressions and clicks, helping you reach a more appropriate audience and potentially improve return on investment. In addition, it supports better relevance signals, which can help maintain or improve quality metrics over time. The other options don’t fit: negative keywords don’t increase impressions, they don’t purposefully lower quality score, and they aren’t used to automatically generate new keywords.
