How do bots contribute to ad fraud, and what can be done to prevent it?

Bots contribute to ad fraud by generating fake impressions and clicks on ads, leading to inflated performance metrics and wasted ad spend. They can mimic human behavior and interactions, making it difficult for advertisers to detect the fraudulent activity. To protect ad campaigns from fake impressions caused by bots, measures such as implementing advanced bot detection technology, using ad fraud prevention tools, setting strict targeting parameters, employing third-party verification services, and analyzing data for irregular patterns can be effective. Regularly monitoring ad performance and adjusting campaign settings can also help mitigate the impact of ad fraud.
