Let’s dive into it👇
Grow Without Ads
1. Outrank Competition with micro-influencers
The holidays are Amazon’s most competitive stretch - ad costs surge, placements tighten, and only brands that break through early win lasting rank visibility.
Most sellers face the same issues:
PPC costs spike 30–50% in Q4
Rankings freeze on page 2
Reviews trickle in too slowly
That’s where Lenny & Larry’s were stuck - until they used Stack Influence. We activated 1,560 influencers who each:
Bought the product on Amazon (a verified purchase)
Shared honestly on social media
Left organic UGC that the brand could repurpose
The result? 🚀 11× sales, ⭐ 525 reviews, 👀 2.3M impressions - momentum ads can’t buy.
Get ahead of Q4 competition. Outrank your category before Black Friday hits.
Decisions That Matter
2. Why your 4:1 LTV:CAC ratio is lying to you
LTV - how much revenue one customer generates over their lifespan
CAC - how much it costs to acquire that customer
A 4:1 ratio = for every $1 spent, you get $4 in return.
Looks great…
But wait for the hidden costs:
Now your breakeven CAC is $35.
You’re not actually scaling profitably; you’re just breaking even.
Solution?
Track real numbers and model:
→ LTV:CAC by cohort (30, 60, 90, 180 days)
→ LTV after returns and discounts
→ Contribution margin per SKU
→ Payback period vs. allowable CAC
→ CAC guardrails by product tier
