What is UGC (user-generated content) in ads?
What counts as UGC in ads?
"UGC" covers two quite different things.
- Genuine customer content. A real customer posts a video or review. The brand asks to use it.
- Paid creator content. A creator is briefed and paid to make something that looks like customer content.
Both are called UGC. They are not the same. We call the second one paid creator content (UGC-style). A paid post made to look spontaneous is still an ad, and viewers may read it differently when they find out.
Why does it matter for ecommerce brands?
The style fits the feed. The same vendor glossary says UGC feels more platform-native than high-production ads1. Rough, handheld video looks like the posts around it, so it can feel less like an ad. That is the appeal. It is a creative choice, not a guarantee of results.
The business questions are plain ones. Who made it? Do you have the right to use it as an ad, and for how long? Was the creator paid, and is that disclosed? Disclosure rules and usage rights vary by country and platform. Your own lawyer decides what applies. We do not give legal advice here.
UGC-style ads also wear out. When the same audience sees the same creative too often, results drop: that is creative fatigue. See how to fix creative fatigue. To compare creative fairly, use a creative testing framework that decides on margin, not click-through rate.
On Meta, automated campaigns such as Advantage+ sales campaigns will happily run UGC-style creative too. The format does not change the measurement question.
For ZFD: We label content by what it is. A creator who was paid is a paid creator.

FAQ

Is UGC always made by customers?
No. A lot of UGC-style creative is made by creators who were briefed and paid. Call it paid creator content, and ask your lawyer how it has to be disclosed where you sell.
Does UGC work better than polished ads?
There is no general answer. Test it against your other creative and judge it on margin.
