Completion Rate = (Views that watched 100%) ÷ Total Views × 100

Conversion Metrics 🔗 Click-Through Rate (CTR) Conversion Percentage of viewers who clicked the link in influencer's content. CTR = (Link Clicks ÷ Impressions) × 100 Example: 2,000 clicks ÷ 100,000 impressions × 100 = 2% CTR

📊 Good Benchmarks 1-3% Instagram Stories 0.5-2% Instagram Feed 2-5% TikTok 🛒 Conversion Rate Conversion Percentage of clicks that resulted in desired action (purchase, sign-up, download). Conversion Rate = (Conversions ÷ Clicks) × 100

Frequently Asked Questions

How often should I track influencer performance? Track engagement metrics weekly during active campaigns. Track conversion metrics in real-time if possible. Compile full performance reports at campaign end and 30 days post-campaign (for delayed conversions).

What's the most important influencer metric? Depends on your goal: Awareness = reach/impressions. Engagement = engagement rate. Sales = conversion rate/ROI. For most brands, ROI is the ultimate metric.

How do I track influencer performance without affiliate links? Use: unique promo codes, dedicated landing pages, UTM parameters, brand lift surveys, or ask customers at checkout "How did you hear about us?"

What's a good ROI for influencer campaigns? Average influencer marketing ROI is $5.78 per $1 spent. Top-performing campaigns see $10-20+ per $1 spent. Aim for minimum 3:1 ROI ($3 revenue per $1 spent).

How long should I track post-campaign? Track for minimum 30 days post-campaign. Some conversions happen weeks after initial exposure. For evergreen content, track for 90 days.

Should I share performance data with influencers? Yes! Sharing performance data helps influencers understand what works. Top performers will use this to improve future content. It builds stronger partnerships.

How do I compare influencers with different follower counts? Use rate-based metrics (engagement rate, conversion rate) not absolute numbers. A 5% engagement rate is good whether influencer has 10K or 100K followers.
