How do I know if an influencer has fake followers?
Check: (1) Engagement rate (should be 5%+), (2) Comment quality (real vs spam), (3) Follower growth (steady vs sudden spikes), (4) Audience demographics (suspicious patterns). InVideo AI does this automatically with authenticity scoring.
How many micro-influencers should I work with?
Start with 5-10 for first campaign. Test different influencers, see who performs best. Then scale to 20-50+ influencers. More influencers = more reach, diversified risk, better data.
