How to choose a Meta Ads agency for your Shopify brand

1. Compare agencies with the same scorecard

Give every shortlisted agency the same brief: your products, margins, current spend, growth constraints and internal resources. Then score the evidence they provide. A polished pitch alone should not earn full marks.

Scoring: 0 = unanswered; 1 = explained but unsupported; 2 = supported by a relevant example or written commitment. Seven areas give a total out of 14. This is a comparison aid we propose, not an industry benchmark or a prediction of results.

Write the evidence beside each score. Resolve gaps in account control, unclear fees or unusable reporting before comparing totals; a high score elsewhere does not fix those issues.

2. Decide what the agency needs to earn back

Evaluate the full cost of the engagement against a credible alternative: your current team, a freelancer or another agency. Include the time your team will still spend briefing, approving creative and maintaining the store.

Start with net sales after discounts and returns. Subtract product costs and variable costs such as fulfillment, shipping subsidies and payment processing. What remains before marketing is the contribution available to pay for acquisition, overhead and profit.

Ask the agency to show a downside scenario as well as the target. A projection based on repeat purchases should state the observation period and use actual customer cohorts where available. Cash arriving months later cannot fund today’s inventory without a financing plan.

Agree on metric definitions

• Platform ROAS: platform-attributed purchase value divided by platform ad spend. Record the attribution settings and revenue definition.
• Blended acquisition cost: agreed acquisition costs divided by new customers in the same period. State whether fees and creative are included.
• Contribution after marketing: net sales minus product, variable operating and marketing costs. Track this alongside customer growth.

These measures answer different questions. None, by itself, proves that the agency caused the growth. Seasonality, promotions, product launches and existing customer demand can affect the result.

3. Inspect the creative process and measurement

Buy a learning process, with clear deliverables

Ask to see how a customer insight becomes an ad concept, how that concept becomes several executions, and how the results change the next brief. Changing a caption or crop is useful iteration, but it is not the same as testing a new customer problem, promise or offer.

Clarify who supplies product samples, films footage, edits, obtains creator usage rights and approves claims. Agree on how many concepts and variations are in scope, where they will run and what counts as a completed deliverable. The testing plan should fit the budget and purchase volume.

Request a sample learning log with a hypothesis, launch date, spend, outcome and next decision. Ask how the team distinguishes an ad problem from a weak offer, landing-page friction or stock limitations.

Require a tracking check before increasing spend

Have the agency document the purchase event, value and currency, pixel and server-side setup, and duplicate-event checks. Shopify specifically warns that old pixel code alongside its Meta integration can cause duplicate or incorrect reporting. See Shopify’s Meta pixel guidance.

Ask how customer data-sharing choices and consent are handled for your store. The agency should explain its implementation and responsibilities instead of treating more tracking as an automatic default.

Shopify’s marketing reports support different attribution models, which assign credit differently across customer interactions. Agree on the models and date ranges used in reviews. See Shopify’s marketing report documentation.

A useful weekly report explains what changed, what the team learned, what it will do next and which decision needs your input. When the budget and data support it, ask how an experiment could test incremental impact rather than relying only on attributed sales.

4. Read case studies as evidence to investigate

A strong case study helps you understand the agency’s reasoning. Ask whether the client had similar margins, purchase frequency, creative resources and operating constraints. Check whether the result concerns Meta alone or several channels together.

For any agency, request the timeframe, baseline and scope behind a headline result. If the public case study omits those details, ask for clarification or an appropriate client reference. Do not assume every improvement came from paid media alone.

5. Agree on the first 90 days

Use this as a starting framework, then adapt it to your budget, data volume and production cycle. It is a review schedule, not a promise of profitability by a particular date.

Agency, freelancer or in-house?

A freelancer can fit a focused media-buying need when your team already handles creative and analytics. An agency can fit a need for coordinated disciplines and broader delivery capacity. An in-house hire can fit a sustained workload that benefits from daily business context. Compare actual responsibilities and total cost; company size alone does not decide the right model.

6. Take these questions into the final meeting

1. Which business constraint would you investigate first, and why?
2. What costs and assumptions are included in our acquisition target?
3. Which creative deliverables are included, and who owns the files and usage rights?
4. How will you check purchase tracking and explain reporting differences?
5. What would cause you to recommend reducing spend?
6. Which comparable result can you explain with a baseline and timeframe?
7. Who will manage our work after the sales call, and how will we review decisions?
8. What are the notice period, extra charges and handoff deliverables?

Be cautious when an agency guarantees a return before understanding the store, cannot explain its measurement, leaves production responsibilities vague or requires you to surrender control of core business assets. Put the final scope and answers in writing.

Common buyer questions

How much should a Shopify brand spend before hiring an agency?

There is no useful universal threshold. Work backward from the total cost, the creative and measurement work required, and enough budget to learn without threatening cash or inventory. If management costs leave little room to test, consider a narrower scope or a different delivery model.

Can I compare agencies using ROAS?

Only with context. Ask for the revenue definition, attribution settings, customer mix, spend and period. Then compare the business economics and the work included. A higher reported ROAS can coexist with less contribution profit.

Should the agency own our ad account?

Our recommendation is to retain business control and grant the access needed to do the work. Specify ownership and access for accounts, data, creative files and licensed assets, plus what transfers at the end of the engagement.
