Kris is managing a campaign where one of the line items is beating the performance goal, yet underdelivering. Which of the following is the recommended approach?

The correct approach is to increase the frequency cap on that line item to serve more impressions. The line item is performing well (beating its goal), but underdelivering, meaning it's not spending its allocated budget or reaching its full impression potential. Increasing the frequency cap allows the line item to show ads to users more often, thereby increasing impression volume and helping it to deliver fully while maintaining its strong performance. Shifting budget away is incorrect because the line item is already performing well; you want to enable it to spend its full budget, not reduce it. Decreasing the frequency cap would further restrict impression delivery, exacerbating the underdelivery issue. Maintaining bids and frequency caps would not address the underdelivery problem, as the current settings are leading to underdelivery despite good performance.
