There is no single formula. Each brand has its own goals when recruiting influencers. Some might want hundreds of influencers promoting their service or product, and others may want only a handful of highly influential voices writing sponsored posts.
Influencers can only see Activate campaigns they are eligible for. Criteria for eligibility can include minimum, geography, and more. We would highly encourage all influencers to completely fill out their Activate profile to maximize their chances of campaign opportunities.
