An advertiser creates a Pin and saves it to a Board. In campaign setup, the Pin cannot be located. Which board did the advertiser choose?

If an advertiser cannot locate a Pin during campaign setup despite having saved it to a board, it is because the board is a Secret board. In Pinterest's advertising ecosystem, only publicly visible content can be promoted as an ad. Here is why the other options are incorrect: Secret Boards: These are private and visible only to the creator and invited collaborators. Because the content is not indexed for public viewing or search, Pinterest's Ads Manager cannot "see" or pull these Pins into a campaign. To use a Pin from a secret board in an ad, the board's settings must be changed to public, or the Pin must be re-saved to a public board. Public Boards: These are the standard boards where Pins are visible to everyone. Ads Manager can easily browse and select Pins from these boards. Protected/Organic: "Protected" is not a standard Pinterest board type in this context. "Organic" refers to the type of content (unpaid), but organic Pins must still reside on a public board to be eligible for promotion.
