A strong kit leads with the numbers brands screen for: follower counts per platform, average views, engagement rate, and audience demographics (age, gender, geography — pulled from platform analytics). Case studies beat logos: one partnership with a concrete result ("drove 1,200 clicks, 9% CTR") outweighs a wall of brand names.
Format conventions: keep it current (stale numbers destroy trust), keep it skimmable, match the visual quality of your content, and version it — some creators tailor kits per niche or per pitch. Rates can live in the kit or in a separate rate card; many creators omit pricing from the kit to keep negotiating room. Tools range from Canva templates to auto-updating services that pull live stats.
