Ecommerce Playbook: Numbers, Struggles & Growth

Meta has fundamentally changed how it targets and delivers ads, and most brands are still operating on the old rules. In this episode, CTC's VP of Paid Media Tony Chopp breaks down the CTC Methodology for Meta advertising: why creative is now the targeting, how Meta's Andromeda and GEM systems make decisions no human operator can match, and the counterintuitive principle that defines how our profit engineers manage accounts every single day.

Topics covered:

• How Andromeda and GEM replaced audience-first targeting

• The breakdown effect and why historical ROAS doesn't predict future ROAS

• Campaign structure: evergreen vs. marketing moment campaigns

• Signal quality, CAPI integration, and event match quality scores

• Budget liquidity and why day-to-day spend variance is a feature, not a bug

• The four-phase framework for solving underspend

• Why turning off ads is the single most common mistake brands make

Key stat: Meta's Andromeda enables a 10,000x increase in model capacity per impression opportunity.

Your platform ROAS is not the truth. It's a story your attribution tool tells you. Luke Austin, breaks down exactly how CTC approaches marketing measurement — and why the gap between platform-reported numbers and actual incremental revenue is where most brands make their worst capital allocation decisions.

This is Part 3 of the CTC Canon Series — our codified methodology across the core disciplines of ecommerce growth. In this episode, Luke covers the full measurement framework: why geo holdout tests are the gold standard, how CTC's database of hundreds of incrementality tests gives every new brand a head start, and what it means to build "progressive truth" over time instead of chasing a single source of truth.

Topics covered:

• Why media efficacy is always in flux — and why any system that treats it as fixed is lying to you

• The measurement gap: reality vs. fiction, and how to move closer over time

• Geo holdout tests explained — how they work, why they're the gold standard

• CTC's incrementality benchmarks by channel: Facebook acquisition (1.14x iROAS), Google Branded (0.27x iROAS), and more

• Why Google branded search dramatically over-reports ROAS

• How iROAS normalization enables true apples-to-apples channel comparison

• The three-stage framework: aggregate benchmark, individual test, accumulated median

• Why iROAS is always subordinate to contribution margin

Most brands forecast from gut feel and ROAS. CTC runs on four interlocked proprietary models that produce a daily P&L forecast with 3.1% accuracy across more than $3 billion in GMV. In Part 2 of the Canon series, Luke Austin breaks down each model, how they connect, and what a Profit Engineer actually does with them

Topics covered:

• Why a single ROAS number can't run a business

• The Spending Power Model — ACoNS curves and what spending power actually tells you

• The Retention Model — forecasting returning revenue cohort by cohort

• The Event Effect Model — how to get daily precision without breaking monthly targets

• The Creative Demand Model (teased — full breakdown in the creative strategy episode)

• How these four models wire together into a connected forecast system

• What R-squared below 0.6 signals about your retention data

• The three optimization points every brand should know: max CM, max revenue, max LTV CM

Key stat: 3.1% forecast accuracy across $3B+ in GMV managed — producing 30%+ revenue growth and 40%+ contribution margin growth.

Every dollar spent on SaaS is a dollar that does not go into ads.

In this episode, Luke Austin sits down with Gil Dyen, Head of Marketing at Rutsu Barefoot, to walk through a real email and SMS platform migration to Omnisend — what drove the decision, what the process actually looked like, and how a 60,000-contact list got fully migrated in under 30 days with less than a working day of direct involvement.

Gil runs marketing at a mid-7-figure DTC footwear brand that has sold 45,000 units in its first 18 months, with a clear mandate: keep SaaS costs lean, reinvest every freed dollar into Meta spend and creative, and build the retention engine that takes the brand from 12% returning customers today to 45% by year three.

Topics covered in this episode:

• Why a bootstrapped DTC brand audits its SaaS stack constantly

• The two criteria that actually drive platform decisions: cost and time

• How Omnisend managed the full migration, from contact database to flow automations

• What the QA process looks like after a migration (and how long it takes)

• The warm-up mechanics: 9 days to re-engage 60,000 contacts

• Why Q4 is the wrong time to switch email platforms (and when to do it instead)

• How an ESP migration becomes a flow audit opportunity

• CTC's Omnisend integration inside Statlas for forecast-connected email tracking

The Canon is a decade of ecommerce methodology distilled into seven categories: technology, forecasting, marketing measurement, Meta advertising, Google advertising, email strategy, and creative strategy. It's not a pitch deck. It's the actual operating system behind how CTC grows 170+ ecommerce brands.

• How CTC's methodology updates in real time through aggregate testing

• Why evaluating agencies by individual talent is an outdated framework

• The role of AI in deploying institutional methodology at scale

Joy Sharma runs CTC's PE7 program for mid to high 7-figure brands pushing toward 8 figures. His claim: if you're stuck at a growth plateau and you've tried more creative, new ad structures, and different platforms, we can tell you what's wrong without even looking at your account. The answer is offer-market fit.

In this episode, Joy breaks down why Facebook's auction forces you to compete against increasingly sophisticated players as you scale spend, why the AOV-to-CAC ratio in your industry determines your ceiling, and how CTC's Marketing Moments service guarantees incremental revenue by solving the offer problem first.

In this episode:

• Why growth plateaus are a business problem, not a marketing problem

• How Facebook's auction works against you at higher spend levels

• The AOV vs. CAC framework that reveals who you're really competing against

• Why the AOV vs. conversion rate log curve determines your offer's viability

• How static images outperform expensive videos when you have offer-market fit

• CTC's Marketing Moments service and the revenue guarantee behind it

• The sequence that matters: product-market fit → offer-market fit → creative strategy

Key insight: Creative strategy should be a volume mechanism, not an efficiency mechanism. If you're trying to solve a business problem with a marketing solution, that's where businesses go to die.
