An advertiser sets up an awareness campaign with the goal of reaching people on Pinterest who are interested in holiday recipes while achieving low cost per mille (CPMs). The campaign is set up with: A lifetime budget of $40,000 for 50 days. Three ad groups targeting food, drink and holiday interests. Two static images, two carousels and two videos. The campaign is pacing to deliver in full but has higher CPMs than the goal. Which action can the advertiser use to improve performance? Select two.

Pausing the ad group with the highest CPM for interests directly addresses the problem of high CPMs by removing the most expensive audience segment, allowing the budget to be reallocated to more efficient segments. Confirming that creative assets are optimized to fit Pinterest best practices is crucial because high-quality, engaging creatives can improve ad relevance and user interaction, which often leads to lower CPMs and better overall campaign performance. Adding an ad group for Beauty interests is unlikely to help, as it introduces a new, potentially expensive audience. Adjusting the campaign budget alone won't reduce CPMs if the underlying issues persist. Extending campaign end dates and switching to custom bids are not guaranteed to lower CPMs and could even increase them if not managed carefully.
