A retail advertiser wants to reach users who have visited their store locator page. What type of targeting will deliver the right creative to this audience?

First-party audience retargeting is correct because it uses data collected directly by the advertiser (in this case, website visits to the store locator page) to re-engage those specific users with relevant ads. This allows the advertiser to deliver tailored creative to an audience that has already shown interest. Geographic targeting would only target users based on their location, not their past website behavior. AdWords API targeting refers to using the API to manage campaigns, not a targeting method itself. Third-party audience targeting uses data collected by other entities, which wouldn't specifically identify users who visited this particular advertiser's store locator page.
