Influencer marketing and user-generated content (UGC) work differently from a brand's own content: the value comes specifically from looking like it wasn't made by the brand, which means the coordination behind it, briefing, selection and usage rights, matters more than it does for content a brand creates itself.
Micro vs macro influencers
Macro influencers (typically above 100,000 followers) offer reach and broad awareness, at a higher cost and generally lower engagement rate per follower. Micro influencers (roughly 10,000 to 100,000 followers) usually have a more engaged, niche-specific audience and cost considerably less, making a handful of micro influencer collaborations often more cost-effective for a specific product launch than one macro placement.
Briefing a collaboration properly
A useful influencer brief covers the key message and any required mentions, what's off-limits (competitor products, specific claims), and posting timeline, while leaving the actual creative execution, how they film it, what they say, to the influencer, since their audience follows them specifically for their own style, not a brand's script. An overly scripted post is usually easy for an audience to spot and tends to underperform a more natural one.
UGC as a separate content source
User-generated content, genuine customers posting about a product without being paid to, or content specifically commissioned from creators to look like organic customer content, is increasingly used in paid ad creative because it reads as more trustworthy than polished brand photography. Actively requesting permission to repost or reuse strong customer content, rather than only relying on paid collaborations, is a low-cost way to build a UGC library over time.
Usage rights: the detail that gets missed
An influencer collaboration agreement needs to specify not just that content gets posted, but where a brand is allowed to reuse it afterward, on the brand's own social accounts, in paid ads, on a website, and for how long. Without that agreed upfront, a brand can find itself unable to legally reuse content it paid for beyond the influencer's own original post.
