If you’re still thinking TikTok is just dance trends and Gen Z antics, think again. The app is now a serious player in the social commerce game, driving impulsive buys, influencing brand trust, and shaping consumer habits far beyond its younger user base. The latest research, powered by strategic prompts and ChatGPT Deep Research, dives into how TikTok impacts purchasing behavior across Gen Z, Millennials, Gen X, and even Boomers—and what brands need to do about it.

Younger generations are already treating TikTok like Google meets QVC, while older users are starting to catch on (slowly, but it’s happening). The platform isn’t just helping people discover new products—it’s flattening the whole path to purchase. From one-click buys in TikTok Shop to creator-backed trust signals, the app is rewriting the rules on how people shop across the board.

Key Takeaways

  • Gen Z leads the pack: 64% use TikTok as a search engine. 55% admit to impulse buying through the app.
  • Millennials follow closely: 70% shop on social media at least occasionally. They balance impulse and research and are very price-aware.
  • In-app shopping is growing: TikTok Shop has been used by 1 in 3 U.S. TikTok users—mostly Gen Z and younger Millennials.
  • Influencer content builds trust: 60% of users trust a product more if introduced by a creator than a brand ad.
  • Boomers and Gen X still hesitate: They favor off-platform purchases, detailed reviews, and traditional e-commerce trust signals.
  • Top categories: Beauty, fashion, gadgets, food, and home goods dominate—especially content that’s visual and easily demoed in a 15-second video.
  • Live shopping and exclusive deals drive engagement, especially among younger users looking for urgency and discounts.
