An advertiser is targeting specific interests and keywords, but wants to reach more relevant people. What should the advertiser do? Select two.

To reach more relevant people, the advertiser should use expanded targeting. This feature allows Pinterest to automatically find additional audiences similar to the ones you've already defined through interests and keywords, broadening reach while maintaining relevance. Additionally, starting to target site visitors (retargeting) is highly effective for relevance. These individuals have already shown interest in the advertiser's brand by visiting their website, making them a highly qualified audience for further engagement. Automatic bidding is a bidding strategy, not a targeting method, and while it can optimize ad delivery, it doesn't directly expand the relevance of the audience. Adding more ads to a campaign increases creative variety but doesn't inherently expand or refine the audience being targeted.
