What is a recommended action when identifying poor performing sites in an ad campaign?

When identifying poor performing sites in an ad campaign, excluding them from future targeting is a recommended action because it helps optimize the overall effectiveness of the campaign. Poor performing sites tend to waste budget and resources without providing the desired results. By excluding these sites, advertisers can redirect their focus and budget towards higher-performing sites that deliver better engagement and conversions. This strategic move helps improve overall campaign performance by ensuring that advertising dollars are spent more effectively.

Keeping underperforming sites active for data collection or allocating more budget to them would not yield beneficial results, as there is no indication that continued investment in poor performers would lead to improved outcomes. Similarly, increasing ads targeted to poorly performing sites would likely exacerbate the inefficiency of the campaign, rather than rectify it.
