Where to find viral UGC hooks, and how to use them in a brief

The best hooks for UGC come from real posts that held attention, read together with the format they opened. Here is where to look and what to keep.

Where to look by hand

  • TikTok and Instagram search. Search the product category, the problem it solves and phrases buyers use. Pick out the posts that clearly beat their account's usual views.
  • Comment sections. The questions and objections in the comments under a popular post are hooks waiting to be written.
  • TikTok's own Creative Center. Its Top Ads show paid TikTok ads that advertisers have agreed to share, which is useful for ad hooks on TikTok. See how it compares.
  • Your own past posts. The opening lines of your best-performing videos are the hooks most likely to work again for your audience.

What to save with each hook

A hook read without its video is missing the picture that made it work. Save it with:

  1. The first line, word for word, spoken or on screen.
  2. The format: a face close-up talking to camera, a creator over app footage, a street interview, a sign held up to the camera.
  3. How far it travelled for its account: views against that account's usual views, so a big account's average post doesn't look like a winner.
  4. A link to the video, so whoever writes the brief can watch the first seconds.

Where Viral Swipe File fits

Viral Swipe File ranks every video by viral factor: its views divided by the account's usual views. A video at x20 did twenty times its creator's normal numbers, whatever the size of the account. Every video comes with its hook pulled out as text, so you read hooks in a list instead of opening videos one by one.

  • Each format page shows that format's top hooks and the niches using it. The formats closest to UGC are listed below.
  • Search by keyword for a product category or a problem, then sort by viral factor.
  • The library is TikToks and Instagram Reels from creators' own accounts. It holds no ad spend or conversion data, so test a hook before you scale it.

FAQ

What is a UGC hook?
The opening line or moment of a user-generated content video: the first seconds that decide whether a viewer keeps watching. It can be spoken, written on screen or shown.
Are Viral Swipe File's hooks from ads?
Viral Swipe File is not an ad library: its videos are TikToks and Instagram Reels as posted on creators' own accounts, ranked by how far each beat its account's usual views. For paid TikTok ads, TikTok's Creative Center shows top ads that advertisers have agreed to share.
Can I use a viral hook word for word?
Use its structure and rewrite the words for your product and voice. A hook copied word for word reads as borrowed, and it may not fit your video.
