Influencer Marketing Glossary

Plain-English definitions of the terms that decide whether an influencer partnership pays off — engagement rate, fake followers, audience quality, reach, and the creator tiers. Each definition includes the benchmark or formula you actually need.

Engagement Rate

Definition: The share of an audience that interacts with a creator's content — usually (likes + comments) ÷ followers × 100. It's the single best quick gauge of whether an audience is real and active.

Engagement rate matters more than raw follower count because it reflects whether people actually respond to a creator. A 1M-follower account with 0.3% engagement often drives fewer real results than a 20K nano-creator at 8%. Calculate and benchmark any account with the engagement rate calculator.

Good Engagement Rate

Definition: A benchmark that varies by platform and tier. Instagram: nano (1K–10K) 5–10%, micro 3–6%, macro 1–3%. TikTok runs higher (nano often 10–18%); YouTube lower (nano ~3–6%).

There's no universal "good" number — compare a creator against others in the same platform and follower tier. Engagement far below the tier norm is a common fake-follower warning sign.

Fake Followers

Definition: Bot accounts, inactive profiles, or purchased followers that inflate a creator's follower count without delivering real engagement or conversions.

Fake followers waste budget by making reach look bigger than it is. Detect them by checking engagement-to-follower ratio, audience quality, growth anomalies, and comment authenticity — or run a free fake follower check.

Audience Quality

Definition: A measure of how many of a creator's followers are real, active people versus bots, mass-followers, and inactive accounts. Often expressed as a "Quality Audience" percentage.

High audience quality means the followers a brand pays to reach are genuine potential customers. It's the core question behind influencer vetting.

Mango Score

Definition: ViralMango's composite 0–100 influencer-quality rating that combines engagement rate vs tier benchmark, quality audience percentage, follower-growth health, and comment authenticity. Above 70 = high quality; below 40 = concerns.

The Mango Score condenses several audience-quality signals into one number so you can compare creators at a glance.

Reach Rate

Definition: The percentage of followers (or total accounts) that actually see a post — unique reach ÷ followers × 100. It differs from engagement rate, which measures interaction rather than visibility.

Reach rate, engagement rate, and view rate measure different things: reach is who saw it, engagement is who interacted, and view rate (on video) is who watched.

Influencer Tiers

Definition: Follower-count bands — nano (1K–10K), micro (10K–100K), macro (100K–1M), and mega (1M+). Smaller tiers usually have higher engagement and lower cost per post.

Tiers matter because benchmarks and pricing differ sharply between them — a "good" engagement rate for a mega-influencer would be poor for a nano-creator.

Lookalike Profiles

Definition: Creators with audience demographics, interests, or behavior similar to a given profile — used to discover new influencers comparable to a proven performer.

Lookalike discovery scales what works: find one creator who converts, then surface others with a similar real audience.

Engagement Pod

Definition: A coordinated group of accounts that like and comment on each other's posts to artificially inflate engagement metrics.

Pod activity makes engagement look organic when it isn't. Comment-authenticity analysis is designed to catch it.

Comment Authenticity

Definition: A signal measuring what share of a creator's comments come from genuine accounts versus bots or engagement-pod participants.

Generic, repetitive, or emoji-only comments from low-quality accounts are red flags that authenticity scoring surfaces automatically.

Frequently Asked Questions

It depends on platform and follower tier. On Instagram, nano-influencers (1K–10K) typically see 5–10% and macro-influencers (100K–1M) average 1–3%. TikTok runs higher (nano often 10–18%) and YouTube lower (nano ~3–6%). Engagement well below the tier norm can signal fake followers. Benchmark any account with the engagement rate calculator.

The most common formula is (likes + comments) ÷ followers × 100. Some definitions add saves and shares to the numerator, or use reach or views instead of followers in the denominator for reach-based engagement.

Fake followers are bot or purchased accounts that were never genuine users. Inactive followers are real people who stopped using the platform. Both lower engagement rate, but fake followers indicate potential fraud while inactive followers are a normal part of any audience.
