Red flags
6 to watch
in any pitch
  • · Undisclosed agency commission on creator fees, or refusal to itemise the talent pass-through on invoices
  • · No audience-quality audit (follower authenticity, engagement ratios, geography match) before contracting
  • · No ASA and CAP Code compliance review on captions, with reliance on 'gifted', '#sp', '#collab', or hashtags buried at the end
  • · No #ad disclosure governance: creators left to label posts themselves with no brand pre-approval workflow
  • · Contracts with no exclusivity window, category-conflict clause, or paid usage and whitelisting rights
  • · Reporting that stops at followers, impressions, and likes, with no engagement quality, CPA, ROAS, or sales attribution

The 5 questions our editors get most often, answered honestly. These apply to influencer marketing as a discipline regardless of city.

Curated by humans

UK influencer marketing pricing is two-layered.
