MARKETING GLOSSARY
Influencer Marketing
DIRECT ANSWER
Influencer marketing is a strategy where brands partner with creators—individuals who have built an engaged audience on platforms like Instagram, YouTube, TikTok, or LinkedIn—to promote products or services. Unlike traditional advertising, influencer content leverages the creator's established trust and authentic voice to reach a targeted audience.
Types of Influencers by Audience Size
Influencers are typically segmented by follower count: nano (1K–10K), micro (10K–100K), macro (100K–1M), and mega/celebrity (1M+). Nano and micro influencers generally deliver higher engagement rates and more niche audience alignment. Macro and mega influencers offer scale and broad reach but at higher cost per post and often lower engagement rates.
Audience size alone is a weak signal. Engagement rate, audience-brand alignment, content quality, and historical conversion data are more predictive of campaign performance. Many brands now prioritize micro influencer programs over single large-spend celebrity deals.
Measuring Influencer Marketing ROI
Performance metrics vary by objective. Awareness campaigns track reach, impressions, and earned media value. Conversion campaigns use unique discount codes, UTM-tagged links, and pixel-based attribution to measure clicks, signups, or purchases. Long-term brand impact is harder to measure but can be captured through brand lift surveys and share-of-voice tracking over time.
FAQ
Influencer Marketing — common questions
How do you find the right influencers for a campaign?
Start with audience alignment: does the influencer's audience match your target customer profile by demographics, interests, and behavior? Then evaluate content quality, engagement authenticity (watch for follower inflation), past brand partnerships, and whether their tone fits your brand. Influencer discovery platforms and manual social search both work.
What disclosures are required for influencer partnerships?
In the US, FTC guidelines require influencers to clearly disclose any material connection to a brand—payment, free product, or other compensation—using plain language like #ad or #sponsored in a prominent position. Requirements vary by country; brands are responsible for ensuring their influencer partners comply.
