What is user-generated content (UGC)?

Why it works

It reads as evidence rather than as claim. A brand saying its product is good is an assertion; a customer saying so is testimony, and audiences discount the two very differently.

In performance advertising, UGC-style creative consistently outperforms polished production in many categories — partly because it fits the feed it appears in, and partly because the informality itself signals that it is not an advertisement.

The rights problem

Someone posting about your product has not given you permission to advertise with it. Platform terms govern the platform's rights, not yours, and using a customer's photograph in paid media without explicit permission is a real legal exposure as well as a relationship one.

Getting permission properly means asking, documenting, and specifying scope and duration. The shortcut — reposting and hoping — works until the person whose face is in the advertisement objects, at which point it is expensive.

UGC and AI recommendations

This is where UGC has acquired a second, larger role. What users say about a brand in reviews, forums and communities is a significant input to how models describe it — see trust graph.

That makes genuine customer sentiment an acquisition input rather than only a marketing asset. A product with consistent, positive, specific discussion is more likely to be recommended when someone asks an assistant for options, without any advertising being involved.

It also raises the stakes on manipulation. Fabricated reviews and astroturfed discussion were always dishonest; now they are also feeding the system that decides whether you get recommended, and platforms and regulators have both become considerably more attentive to it.
