## FAQs

### What is influencer marketing?

Influencer marketing is partnering with individuals who have engaged audiences — creators, experts, personalities — to promote a brand to their followers. It leverages the trust and reach the influencer has built, so their endorsement carries authenticity and social proof that brand advertising can't replicate. It ranges from sponsored posts to long-term ambassadorships across social platforms.

### What are the tiers of influencers?

Roughly: mega/celebrity (millions of followers, broad reach, high cost, lower engagement), macro (hundreds of thousands, broad but more niche), micro (roughly 10k–100k, niche and highly engaged), and nano (under ~10k, very niche, highly trusted, low cost). Smaller tiers often have higher engagement and trust within their niche and better cost-efficiency, while larger tiers offer reach. The right tier depends on goals and budget.

### How is influencer marketing different from creator-generated content?

Influencer marketing primarily pays for access to the influencer's audience — content runs on the creator's channels to reach their followers. Creator-generated content (CGC) pays a creator to produce authentic-style content that the brand then runs on its own ad accounts. Influencer marketing buys reach and the creator's audience trust; CGC buys the content itself. They overlap, and whitelisting blends them.

### What is influencer whitelisting?

Whitelisting is when an influencer grants the brand permission to run paid ads through the influencer's own handle. The ads appear to come from the creator (keeping authenticity and audience trust) while the brand controls targeting, budget, testing, and optimization — and can reach beyond the influencer's own followers. It combines influencer credibility with performance-marketing control, and requires documented permission and proper disclosure.

### How is influencer marketing measured?

By goals: reach and impressions and engagement for awareness; clicks, promo-code redemptions, affiliate links, and conversions for performance; and brand lift or sentiment for brand goals. Because influencer impact can be diffuse, trackable mechanisms (unique codes, links, landing pages) help attribute results, and engagement quality and audience fit matter more than raw follower counts. Disclosure compliance (e.g. #ad) is required throughout.
