An advertiser enables expanded targeting to increase scale across its awareness campaigns. Which signals from the Pin are used to find additional people on Pinterest to target?

Expanded targeting leverages user engagement signals from the Pin itself to find additional relevant audiences. This includes interactions like saves, clicks, and close-ups, which indicate interest in the Pin's content. By analyzing these engagement patterns, Pinterest's algorithm can identify other users with similar interests, thereby scaling the campaign beyond the initial targeting parameters. While landing page content is important for conversion campaigns, it's not the primary signal for expanding awareness campaign reach in this context. Pinterest user age is a demographic targeting option, not a signal derived from the Pin's engagement. Asset length is a creative attribute and doesn't directly inform audience expansion based on user interest.
