Meta Ads Agency
Meta ads for ecommerce, run on contribution margin
Facebook and Instagram advertising for Shopify and DTC brands. Advantage+ Shopping, catalog ads, a creative-testing engine, and Conversions API tracking — reported on the number your P&L can feel, not the one Ads Manager flatters.
- Advantage+ Shopping + structured creative testing
- Conversions API + Pixel, reconciled to Shopify revenue
- Prospecting, retargeting, and catalog ads in one account
- Pay-on-results option for Shopify and DTC brands

Not in-platform ROAS
San Francisco, USA
In-house team
Conversion is a Meta ads agency headquartered in San Francisco, working with ecommerce and Shopify brands. Meta renamed Facebook Ads Manager to Meta Ads Manager; the buyer intent didn't change, but the platform did — Advantage+ automation, signal loss after iOS privacy changes, and a delivery system that now rewards creative volume over audience micro-targeting. We built our practice around those realities rather than the 2019 playbook.
Every account runs on the same loop: fix tracking first (Conversions API, event match quality, catalog hygiene), establish a structured creative-testing cadence, feed validated winners into Advantage+ Shopping, and report on blended MER and contribution margin after ad spend. Because we also run CRO and Shopify development, the landing experience behind every ad is part of the program — not someone else's problem.
Why most Meta ads accounts stall
Three ways ecommerce brands burn Meta budget
We audit a lot of Meta accounts before taking them on. The failure modes repeat.
ROAS that only exists in Ads Manager
In-platform ROAS looks healthy while blended MER falls and contribution margin goes negative. Broken Conversions API, no server-side events, and view-through attribution inflating results. We reconcile Meta's numbers against Shopify revenue before we believe any of them.
Audience tinkering in an era that rewards creative
Dozens of interest stacks and lookalikes, three ad creatives that haven't changed in months. Meta's delivery system now finds the audience if you give it enough creative signal. We invert the ratio: few audiences, many creatives, a weekly testing cadence.
Advantage+ turned on, nothing feeding it
ASC is only as good as the creative pipeline and catalog data behind it. Turned on without a testing engine, it finds a local maximum and plateaus. We run structured tests alongside ASC and promote winners into it continuously.

- Cart drawer + checkout CRO
- Post-click speed fixes
Reporting & Scaling
Weekly readouts on spend, blended MER, contribution margin after ads, and creative performance. Scaling rules tied to margin thresholds, not to platform-reported ROAS alone.

Our Meta ads process
Tracking first, then creative, then scale

Audit & tracking fix
Full account audit, Conversions API and Pixel implementation check, catalog review, and reconciliation of reported results against real revenue. Fixes ship in the first two weeks — before we spend a dollar on strategy.
Restructure & baseline
Consolidated campaign structure, Advantage+ and manual mix set, exclusions in place, and a clean baseline for MER and contribution margin so every later change is measurable.
Creative-testing engine
The weekly cadence starts: new hooks, angles, formats, and offers tested against controls. Winners promote into Advantage+ Shopping; losers retire. Creative production runs in-house so the cadence never stalls.
Scale on margin
Budget increases follow contribution-margin thresholds, not platform ROAS. Landing page and offer CRO run alongside so a better funnel absorbs the extra traffic. Reporting shows the cumulative margin the program generated.
Why Conversion for Meta ads
A Meta ads team that owns the whole funnel
Contribution margin, not ROAS theatre
We report blended MER and margin after ad spend, reconciled to your Shopify revenue. If Ads Manager says 4× and the P&L says break-even, we tell you it's break-even.
Creative volume built in
Static, video, UGC, and AI UGC production in-house on a weekly cadence. The delivery system rewards creative signal; we make sure there's always fresh signal to reward.
Tracking we can defend
Conversions API, event match quality, and Aggregated Event Measurement implemented and audited. Signal loss is a solved problem when the plumbing is right.
Ecommerce and Shopify only
Catalog ads, Advantage+ Shopping, post-purchase exclusions, and Shopify revenue reconciliation are native to how we work — because ecommerce is the only vertical we run Meta for.
CRO and dev under the same roof
Landing pages, cart drawers, and checkout flows are tested and built by our own CRO and Shopify development teams. The post-click experience is inside the program, not outside it.
Pay-on-results option
For qualifying Shopify and DTC brands, fees track the incremental contribution margin the program generates. When it doesn't scale profitably, you don't pay as if it had.
