Quick Answer

How did Adverio grow Pets Favorite's sales while reducing ad spend waste?

Adverio installed profit governance before scaling spend. By pruning wasteful ad targets, protecting Buy Box and inventory health, and layering reach only after efficiency was proven, Pets Favorite grew sales +70% YoY while TACoS dropped from 16.8% to ~10% — all within four months including Prime Day.

Scaling Profitably in a High-Growth Pet Category

Pets Favorite wasn't struggling to grow — they were struggling to grow profitably.

In May, TACoS hit 16.8%, above a 13.5% guardrail, while sales were already climbing +44.7% YoY. Leadership sees growth, but profit gets thinner each week — and Prime Day can turn a controllable problem into a runaway one.

Adverio didn't "buy growth." We installed governance to prune waste fast, protect conversion constraints (Buy Box + inventory), and scale only what earned the right to scale.

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 during Prime Day volatility

Why This Was Hard

Three compounding problems happening at the same time

Ad Waste at Scale TACoS at 16.8% with fast-growing revenue means the dollar bleed is accelerating — not shrinking — every week.
Buy Box + Inventory Gaps Stockouts and eligibility issues suppressed conversions, making efficiency metrics look artificially better while real sales were lost.
Prime Day Pressure A high-spend event on top of an already-inefficient base risks compounding the problem by 3–5x in a single week.
Repeat Purchase Gap Without Subscribe & Save strength, every sale required buying a new customer — keeping TACoS structurally high.

The Challenge

By month, the pattern was clear: growth existed — but governance was lagging.

Month 1

May — Guardrail Breached

TACoS 16.8%

Sales YoY +44.7%

TACoS broke through the 13.5% guardrail. Revenue was climbing fast — but margin was getting thinner with every dollar spent.

Month 2

June — Conversion Constraints

TACoS 14.5%

Sales YoY +45.9%

Buy Box gaps and stockouts muted real upside. Account management gaps were creating wasted-spend risk underneath the surface.

Month 3

July — Prime Day Stress Test

TACoS ~12%

Sales YoY +58%

Consumer behavior shifted fast. The system held — because fast controls replaced reactive budget spikes. PPC governance was already in place before the event.

Month 4

Aug → Early Sept — Controlled Scaling

TACoS ~10%

Sales YoY +70%

Once the base was clean, Sponsored Display video was layered in to amplify winners — not cover up waste.

This was not "we need more ads." This was profit governance under growth pressure — and it required a structured system, not more spend.

Adverio's System: Growth-as-a-Service

Structured controls first. Expansion second.

TACoS Governance

Reset waste thresholds — search terms, targets, product ads
Faster negations + pausing rules for underperformers
Spend only flowed to segments that proved profitability

Result: TACoS compression started immediately — not "after we collect more data."

Winner-Only Scaling

Spend funneled into proven converting campaign + 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 + Inventory Protection

Buy Box gaps and stockouts escalated early
Spend constrained when supply or eligibility couldn't support conversion
Prevented "fake efficiency" created by suppressed sales

Result: The conversion engine stayed intact while scaling.

Repeat Purchase Engine

Expanded Subscribe & Save with coupon mechanics
Increased 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 + 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.

Every step earned the right to the next. Governance before growth — that's the Adverio system.

What Drove It

Four reasons the system worked

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

Governance before spend

Waste was cut before budgets were expanded. Every dollar had to earn its place before the next one followed — no growth-by-overspend.

Prime Day held — not survived

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

Repeat revenue reduced CAC pressure

Subscribe & Save momentum meant TACoS got structurally easier each month — the base was stickier, not just bigger. See our Amazon account management approach.

Reach layered only after efficiency

SB + SD video came last — amplifying proven winners via Amazon PPC management, not masking waste with impressions.

The Lesson

Scaling without structure creates volatility.

Stabilization with governance creates enterprise growth capacity.

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, implementing 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 (Total Advertising Cost of Sales) measures ad spend against total revenue — not just ad-attributed revenue. It reveals the true margin impact of advertising across the entire business, making 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 maintains rapid-response protocols — without breaking efficiency guardrails. See how our Amazon PPC management handles high-volatility events.

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 — the denominator grows without proportional ad spend increases.

When does Adverio introduce Sponsored Brands and Sponsored Display video?

Only after the efficiency base is clean. Adverio layers SB and SD video after core TACoS governance is in place — so incremental spend amplifies proven winners. Learn more about our Amazon PPC management approach.
