小布的目標對象並未涵蓋在潛在目標消費者提供的區隔中。 請問他還可以選擇哪個合適的選項，影響潛在顧客的購買決策？

Custom Intent Audiences are the best choice because they allow advertisers to define their ideal audience based on specific keywords, URLs, or apps that reflect their interests and purchase intent. This is crucial when pre-defined in-market segments don't capture the target audience. Standard Remarketing (Standard Retargeting) focuses on re-engaging users who have previously interacted with the business, not reaching new potential customers whose interests aren't covered by existing segments. Demographics (Targeting Demographics) is too broad and doesn't account for specific purchase intent. Similar Audiences (Lookalike Audiences) finds users similar to an existing audience, which wouldn't help if the initial target audience isn't already defined within an in-market segment.
