Pets Favorite Amazon Case Study:
+70% Sales YoY With TACoS Cut From 16.8% to ~10%

The Setup

Scaling profitably in a high-growth pet category

Pets Favorite was not struggling to grow. It was struggling to grow profitably. In May, TACoS hit 16.8%, above the 13.5% guardrail, while sales were already climbing +44.7% YoY. Leadership saw growth. Profit got thinner every week. Prime Day was weeks away, and a high-spend event on an inefficient base turns a controllable problem into a runaway one.

Adverio did not buy growth. We installed governance to prune waste fast, protect the conversion constraints that actually move sales, and scale only what earned the right to scale.

Executive Summary

How did Adverio grow sales while cutting ad waste?

Adverio installed profit governance before scaling spend. We pruned wasteful ad targets, protected Buy Box and inventory health, and layered reach only after efficiency was proven. Pets Favorite grew sales +70% YoY while TACoS fell from 16.8% to ~10%, inside four months that included Prime Day. This was not a media problem. It was a governance problem, and governance is what fixed it.

The Objective

What Pets Favorite needed to achieve

  • Drive TACoS into single digits without slowing growth.
  • Sustain aggressive YoY momentum while protecting contribution margin.
  • Build repeat-purchase strength, not just first-order spikes.
  • Hold control through Prime Day volatility.

The Challenge

Three compounding problems at once

Growth existed. Governance was lagging. Month by month, the pattern was clear.

Month 1 · May

Guardrail Breached

TACoS 16.8%
Sales YoY +44.7%

TACoS broke the 13.5% guardrail. Revenue climbed fast. Margin thinned with every dollar spent.

Month 2 · June

Conversion Constraints

TACoS 14.5%
Sales YoY +45.9%

Buy Box gaps and stockouts muted real upside and created wasted-spend risk underneath.

Month 3 · July

Prime Day Stress Test

TACoS ~12%
Sales YoY +58%

Behavior shifted fast. The system held because controls were set before the event.

Month 4 · Aug → Sept

Controlled Scaling

TACoS ~10%
Sales YoY +70%

With a clean base, Sponsored Display video amplified winners instead of covering waste.

Diagnosis

Not an ad volume problem. A profit governance problem under growth pressure. The fix was a structured system, not more spend.

Growth-as-a-Service

Adverio's System

Structured controls first. Expansion second.

TACoS Governance

  • Reset waste thresholds across search terms, targets, and product ads.
  • Faster negations and pausing rules for underperformers.
  • Spend only flowed to segments that proved profitability.
Result

TACoS compression started immediately, not after collecting more data.

Winner-Only Scaling

  • Spend funneled into proven converting campaign and ASIN sets.
  • Budgets kept lean to avoid growth-by-overspend.
  • Expansion only after efficiency held.
Result

Growth accelerated while TACoS continued to fall.

Prime Day Control System

  • Dayparting to avoid paying peak CPCs blindly.
  • SOP resets during the event to prevent runaway spend.
  • Rapid response to behavioral shifts without breaking guardrails.
Result

Prime Day became a stress test the system passed, not a volatility spike.

Buy Box and Inventory Protection

  • Buy Box gaps and stockouts escalated early.
  • Spend constrained when supply or eligibility could not support conversion.
  • Prevented the fake efficiency created by suppressed sales.
Result

The conversion engine stayed intact while scaling.

Repeat Purchase Engine

  • Expanded Subscribe & Save with coupon mechanics.
  • Grew repeat-purchase contribution toward ~20% of sales.
  • Reduced dependence on constantly buying new customers.
Result

TACoS got structurally easier because the revenue base got stickier.

Controlled Reach Layering (SB + SD Video)

  • SB and SD video introduced only after the base was cleaned.
  • Used to capture seasonal demand and refresh presence.
  • Reach amplified winners, not waste.
Result

Incremental growth without sacrificing efficiency.

Your sales can look strong while your TACoS quietly drifts.

That gap is where margin leaks.

What Drove It

Four reasons the system worked

The numbers are in the At a Glance box above. Here is the thinking behind them.

Reason 01

Governance before spend.

Waste was cut before budgets expanded. Every dollar earned its place before the next one followed. No growth-by-overspend.

Reason 02

Prime Day held, not survived.

The event ran as a controlled stress test. Dayparting and SOP resets meant the spend spike never became a margin bleed.

Reason 03

Repeat revenue cut CAC pressure.

Subscribe & Save momentum made TACoS structurally easier each month. The base got stickier, not just bigger. See our Amazon account management approach.

Reason 04

Reach layered after efficiency.

SB and SD video came last, amplifying proven winners through Amazon PPC management, not masking waste with impressions.

The Structural Recovery

Pets Favorite moved from 16.8% TACoS with thinning margin to ~10% TACoS at +70% YoY growth in four months, with Prime Day in the middle.

The Lesson

Scaling without structure creates volatility

A rising TACoS looks like an ad problem. The usual reflex is better targeting, lower bids, or a new campaign type. None of that holds when the base is broken.

A brand growing +44.7% YoY with a 16.8% TACoS is not under-optimized. It is under-governed. The spend is outrunning the controls.

Stabilization with governance creates enterprise growth capacity. The sequence matters more than the tactics. Cut waste before you expand budgets. Protect the Buy Box and inventory before you scale traffic, because spend on a suppressed listing buys nothing. Build a repeat-purchase base so the denominator grows without proportional ad cost. Then, and only then, layer reach to amplify what already works.

Do it in that order and Prime Day becomes a stress test you pass instead of a spike that wrecks the quarter. Do it out of order and you fund your own volatility. Pets Favorite did not need more ads. It needed a system that earned every next move.

The Verdict

If your growth looks strong but your TACoS is drifting, we will isolate what is limiting profit and design the control plan.

FAQ

Common questions about Amazon profit governance

How did Adverio reduce TACoS without slowing sales growth?

Adverio installed profit governance before scaling spend. By resetting waste thresholds, running faster negations, and constraining budgets until efficiency was proven, TACoS dropped from 16.8% to ~10% while sales accelerated to +70% YoY, all within four months.

What is TACoS and why does it matter more than ACoS?

TACoS, or Total Advertising Cost of Sales, measures ad spend against total revenue, not just ad-attributed revenue. It shows the true margin impact of advertising across the whole business, which makes it a more accurate profitability signal than ACoS alone.

How does Adverio handle Prime Day without letting spend run away?

Adverio uses dayparting to avoid paying peak CPCs blindly, runs SOP resets during the event, and keeps rapid-response protocols ready, all without breaking efficiency guardrails.

What role does Subscribe & Save play in Amazon profitability?

Subscribe & Save builds a recurring revenue base that reduces dependence on constantly acquiring new customers. When repeat purchases grow as a share of total sales, TACoS becomes structurally easier to control because the denominator grows without proportional ad spend.

Pets Favorite is one of dozens.
