In short: A UGC ad is a creator-style video that a brand runs as a paid ad. To make them work, get the rights for paid use in writing, brief creators for several hooks rather than one script, test one variable at a time, and plan replacements because ads wear out. This guide covers the brief, a simple test method, the metrics guides name and the compliance points for beauty and fashion.
What are UGC ads?
JoinBrands defines a UGC ad as paid advertising content created by independent creators rather than the brand, which aims to convert through authenticity instead of polish. Put simply, UGC ads are the paid-media use of the videos described in what UGC means in marketing. GoMarble’s guide gives the reason they suit social feeds: they look like content people are already watching there. The same guide notes an exception for luxury positioning, where polished studio creative may fit better.
Get the rights for paid ads first
A creator’s video is not automatically yours to advertise with. Rate guides quote a base price for limited use and add a premium for paid use and longer terms (see UGC rates), and the licence should say so in writing. There are two routes:
- Licensed ads: you download the video and run it from your own ad account.
- Whitelisting: the ad runs through the creator’s own account. On TikTok, Spark Ads work this way; TikTok’s help centre says using another creator’s post requires their authorization and that the duration of the authorization code can be customised.
The two are usually priced separately. Details are in UGC usage rights explained.
A common UGC ad structure
JoinBrands describes UGC ads as typically following four beats: a hook that stops the scroll, a relatable problem, a natural product demonstration and an outcome or benefit. For beauty and fashion you can adapt that into a call to action at the end:
- Hook: the first line or visual.
- Demo: the product being used, texture, fit or movement.
- Proof: the creator’s honest experience, reviews, or a genuine before-and-after where allowed.
- Call to action: what to do next.
More hook types are in UGC video ideas and hooks.
How to brief creators for ads
NoGood’s beauty guide says to give creators briefs, not scripts, and to include the top product benefits, visual examples, length and format, what not to say and a request for subtitle-friendly footage. JoinBrands suggests three to five variations as deliverables. In practice, ask for:
- Two or three different opening hooks on the same core video.
- Raw or unedited files if you plan to re-cut, plus a captioned version.
- Vertical 9:16 framing with faces and text away from the edges.
- Claims limited to the list you supply, and a note on how disclosure will be handled.
On safe zones, Billo’s guide to Meta placements advises keeping key content away from roughly the top 14% of a 9:16 frame and the bottom 20–35%, where profile details, captions and buttons appear. Treat this as a starting point and use the preview tools in your ad account. A full template is in the UGC brief template for beauty and skincare.
How to test UGC ads
Vidovo says to keep audience, offer, landing page and campaign objective the same while testing different creator videos. Change one thing at a time: the hook, the creator or the offer. Its list of variables also includes demonstration, length and call to action. 8x.social suggests asking diagnostic questions of each result — did this hook work, did this creator type work — rather than just picking a winning video.
On timing, sources differ. JoinBrands suggests running variations as separate ad sets for three to seven days at equal budgets. GoMarble uses 14 days for comparing UGC with polished creative. Vidovo gives no fixed window but warns against switching ads on and off based on the first few hours of data. Start with a small testing budget and scale only the ads that show buying intent.
Metrics: what they mean
| Metric | What it tells you |
|---|---|
| Thumb-stop / hook rate | How many people stop to watch the opening (definitions vary by tool) |
| Click-through rate (CTR) | Share of viewers who click the ad |
| Cost per acquisition (CPA) | Ad cost per purchase or sign-up |
| Return on ad spend (ROAS) | Revenue earned per unit of ad spend |
Vidovo names these alongside cost per click and conversion rate. Guides also publish benchmark figures, but their sources are often unstated, so compare against your own account history instead.
Creative fatigue and when to refresh
8x.social says even strong ads fatigue: the audience sees the same hook and performance slows, so it advises varying assets before performance drops. JoinBrands suggests refreshing winning ads every four to six weeks and pausing ads when click-through falls sharply, though it does not say where that figure comes from. The complete UGC guide cites a beauty-UGC guide recommending a refresh every two to three weeks when scaling. Rather than following a calendar, watch your own numbers and keep new hooks in reserve.
Compliance for ads
- Claims: NoGood warns against saying “dermatologist-approved” unless substantiated. See cosmetic claims in UGC.
- Disclosure: paid or gifted content must be labelled where it is published. See UGC disclosure rules.
- Platform policies: Meta, TikTok and others have their own ad rules that apply on top; check the current versions.
Rules vary by country and this is not legal advice.
Where Usicri fits
On Usicri, the brand sets the payout per video, reviews every submission and pays only for approved videos, plus a platform fee of 0%. An approved, paid video comes with a non-exclusive, worldwide licence without time limit that covers advertising (section 5 of the Terms of Service), so you can run it as an ad from your own account.
Ads run through the creator’s own account are not included and would need separate agreement. Usicri does not check videos or campaigns for advertising-law compliance; each side does that itself. See open campaigns.
