Why is the engagement-to-click rate so low?

Most engagements are passive (auto-likes, saves) or non-buying-intent (comments). Of the people who actively engage, maybe 5-15% click through. Of those, only a few percent buy. The full funnel multiplies down dramatically — 150k followers can become 30 sales easily.

Influencer grants brand permission to run paid ads from the creator's handle. Vastly extends post reach + targeting precision. Typically costs 20-50% of organic post fee. Common addition: $5,000 organic post + $2,000 whitelisting = $7,000 deal that often outperforms a $7,000 organic-only.

How do I measure influencer ROI accurately?

Three layers: (1) discount code attribution — clean signal but underestimates non-code conversions, (2) UTM URL attribution — captures direct clicks but loses to brand search and dark social, (3) lift study — measure conversion rate during/after campaign vs control period; messy but most honest. Use all three; settle on lift study for major spends.

Influencer marketing — what the actual ROAS looks like

Influencer marketing has one of the widest CPA distributions of any channel. Top creator with perfect fit + strong creative = 5-10x ROAS. Wrong creator + generic creative = 0.3x ROAS (lose money). Until you measure, you're guessing.

The funnel

followers → engagements (likes/comments/saves) → site clicks → conversions

Each stage drops dramatically. Default scenario: 150k followers, 3% engagement, 3 posts → 13,500 engagements; 8% CTR → 1,080 clicks; 3% conversion → 32 sales × $95 AOV = $3,040 revenue. ROAS 0.61 — losing money.

That's the realistic baseline. Improving to 2x+ ROAS requires:

Better creator-product fit (engagement → click % rises 2-3x)
Story-driven creative (not just product placement)
Discount code or unique URL (captures attribution leak)
Multi-post campaigns (3+ exposures before action)

Tier benchmarks

Mega (1M+ followers): ROAS 0.3-1.5x typical. Brand impact > performance.
Macro (100k-1M): ROAS 0.5-3x. Sweet spot for most brands.
Mid-tier (10k-100k): ROAS 1-5x. Often best-performing.
Nano (1k-10k): ROAS 2-10x for niche fits. Hard to scale.

Hidden costs to add

Product gifting (typically 10-20% of fee in product cost)
Shipping + fulfillment for review units
Internal time for brief, content review, posting coordination
Whitelist ads / paid amplification (often 30-50% of organic creator fee)
