The platform says daily searches are up 40% year-over-year and argues that discovery, consideration and conversion increasingly happen within a single app session — an internal concept it calls a “collapsed funnel.” TikTok has built automated buying and AI-driven campaign tools such as Smart+ and GMV Max, and is launching a new global campaign, “TikTok Funnel HQ,” to demonstrate full-funnel measurement and performance capabilities. Agency and advertiser sources cited in the article report that some ad budgets are shifting to TikTok, often from Google, as marketers test TikTok alongside search for categories with strong intent signals.
