Which ad format is best suited for a limited-time promotion on TikTok?

The Branded Hashtag Challenge is particularly effective for limited-time promotions on TikTok because it encourages user-generated content and collective participation around a specific theme or message within a designated timeframe. This format leverages TikTok's community-focused nature, prompting users to engage with the brand by creating their own videos that align with the challenge's theme. With a limited-time promotion, generating buzz and excitement is crucial, and a Branded Hashtag Challenge can rapidly amplify reach and engagement, driving more users to participate and spread the word within a condensed period.

In contrast, while In-Feed Ads can effectively deliver immediate messages to users and may support time-sensitive promotions, they do not inherently encourage the same depth of engagement and user interaction as a Branded Hashtag Challenge. TopView Ads, while offering high visibility by appearing at the top of the feed, typically focus on brand awareness rather than active user participation, making them less effective for generating interactive and engaging content during a promotion. Collection Ads cater more to product showcases, providing a shopping experience rather than driving participation or interaction, which is ideal for promotions that need immediate user involvement.
