The ecommerce agency that coordinates AI commerce and paid media is one that runs ads, email, and AEO off a single product feed and reports on profit, not ROAS. Most agencies that call themselves full-stack are three separate teams in a trench coat. Here are the seven questions that tell you which one you are talking to.
I built a $10M clothing brand and spent over $5M of my own money on Facebook ads before I ever ran an agency. I learned the hard way that disconnected channels quietly bleed money. Ask these before you sign anything.
1. How do you coordinate paid media, email, and AEO as one plan?
A strong partner runs all three off one strategy and one calendar, so a product push hits ads, email, and your AI-readable content in the same week. A good answer sounds like: "Here is how a single promotion moves across every channel." The red flag is a separate lead for each service who never talks to the others, because that is three invoices pretending to be a team.
What a good answer sounds like
They walk you through one shared plan where paid acquisition, retention, and discovery feed each other. They name the person who connects the channels. That person is not you.
2. Who owns and maintains the product feed?
One named person or team should own your feed, because it is the source of truth for Google Shopping, Meta catalog ads, and AI shopping agents. A good answer names that owner and a QA cadence for titles, attributes, and availability. The red flag is "Shopify handles that automatically," which means nobody is watching when it breaks.
What a good answer sounds like
They treat the feed as infrastructure, not an afterthought. Google Merchant Center rules change, attributes get dropped, and a strong partner catches it before your impressions do.
3. Do you measure profit or just ROAS?
The right answer is profit, full stop. ROAS ignores margin, returns, discounts, and fulfillment, so a 4x ROAS campaign can still lose money on a low-margin SKU. A good partner reports contribution margin and blended marketing efficiency, often tracking a metric like MER across all channels. The red flag is a dashboard that only shows platform-reported ROAS.
What a good answer sounds like
They ask for your margins and COGS in the first conversation. Data does not lie, and a partner who wants profit numbers early is a partner who plans to grow profit.
4. What is your agentic-commerce readiness process?
A real process gets your store ready for AI assistants to read, trust, and recommend your products when a shopper asks what to buy. A good answer covers structured data, clean feeds, and content that answers buyer questions directly, backed by Schema.org Product markup. The red flag is a blank stare, or treating AEO as "just SEO with a new name."
What a good answer sounds like
They explain how AI shopping agents evaluate a store and what makes a product get recommended. Everybody is asking this question right now, and it is mostly unanswered. The partner who has a real process is rare.
5. How do you report, and how often?
You want a regular report that ties spend to profit across every channel in plain language, not a wall of screenshots. A good answer is a cadence, a single source of truth, and a human who explains what changed and why. The red flag is "we will send you the platform dashboards," because raw dashboards are not reporting.
What a good answer sounds like
They show you a sample report before you sign. You can read it in five minutes and know exactly what your money did.
6. Who actually does the work on my account?
Ask who touches your account day to day, because the person on the sales call is often not the person running your ads. A good answer names the senior operators on your account and keeps them stable. The red flag is a polished pitch followed by a junior handoff you never agreed to.
What a good answer sounds like
They introduce the actual team. We do not promise specific results. We promise exactly what our team will do, and we tell you who is doing it.
7. What happens in the first 90 days?
A strong partner has a clear first-90-days plan: audit the feed, fix tracking, align the channels, and set the profit baseline before scaling spend. A good answer is specific and sequenced, per guidance from groups like the Data & Marketing Association on measurement-first onboarding. The red flag is "we will hit the ground running," which usually means spending your budget before they understand your business.
What a good answer sounds like
The first month is about truth, not scale. They fix the plumbing, prove the numbers, then grow. That order matters.
How We Chose These Questions
These seven come from running paid media, email, and AEO together for Shopify brands between $500K and $10M, plus my own years spending seven figures on ads for a brand I owned. Each question exposes whether an agency is actually coordinated or just bundling services on one invoice.
FAQ
Q: What does a full-stack Shopify growth partner actually do?
It runs paid media, email and SMS, and answer engine optimization as one connected plan, off a single product feed. The point is coordination, not a menu of separate services.
Q: Why does the product feed matter so much?
Your feed is the source of truth for Google Shopping, Meta catalog ads, and AI shopping agents. If nobody owns it, your ads and your AI visibility both degrade quietly.
Q: Should a Shopify agency report ROAS or profit?
Profit. ROAS ignores margin, returns, and fulfillment, so a high ROAS can still lose money. A real partner reports contribution margin across every channel.
Q: What is agentic-commerce readiness?
It is preparing your store so AI assistants can read, trust, and recommend your products. That means clean structured data, accurate feeds, and content that answers buyer questions directly.
