Ecommerce Marketing Agency That Grows Profit and How to Vet One
An ecommerce marketing agency should be judged on profit after ad spend, not on revenue or ROAS alone. Ask for results from stores with similar margins and order values, keep ownership of your ad accounts, store data and creative, and check every proposal before you sign.
What an ecommerce marketing agency does
It runs the channels that turn store visitors into orders: paid search and shopping ads, paid social, email and SMS flows, marketplace listings, product page and checkout testing, and sometimes SEO and creative production. Some agencies take the whole stack, others own one channel such as Meta ads or email. A store under a few million in annual revenue usually gets more from one channel done well than from five done thinly.
Agency, freelancer or in house hire
An agency brings a team and a repeatable process. A freelancer brings focus at a lower fee, but one person has one skill set and one holiday calendar. An in house marketer knows your catalog best but needs tools, budget and a manager. Many stores start with a focused agency or freelancer for paid media, then hire in house once the numbers are stable. Our guide to how to hire a marketing manager covers that step.
Proof that matters for a store
- Case work from stores with a similar average order value, margin and repeat purchase rate, not only large brands.
- Results stated as contribution margin, new customer cost and payback period, not only ROAS and revenue.
- A clear view of how they separate new customers from returning ones, since retargeting inflates ROAS.
- Named people who will work on your account, and how many other stores each person handles.
- Experience with your platform, whether Shopify, WooCommerce, BigCommerce or Amazon.
Red flags in an ecommerce agency proposal
- A promised ROAS or a guaranteed revenue number.
- Ad accounts, pixels and the email platform owned by the agency, not by you.
- A fee based only on a share of ad spend with no cap or review date.
- A six or twelve month term with no written exit.
- Monthly reports that show impressions and clicks but never margin.
- Generic strategy slides that never mention your products or your customer.
Questions to ask on the first call
- What will you do in the first thirty days, and what will I see at the end of them?
- How do you measure new customer acquisition separately from repeat buyers?
- Who owns the ad accounts, the creative files and the audience data if we part ways?
- What happens if results are below plan in month three?
- Which of your stores left in the past year, and why?
What ecommerce marketing agencies charge
Most charge a monthly retainer, often with a setup fee. Paid media work may add a percentage of ad spend, and some agencies tie part of the fee to revenue. Pricing varies a lot by scope and store size, so ask for a written scope before you compare quotes. Percent of spend models reward the agency when you spend more, so look for a review date and a cap. A short notice period, such as thirty days after an initial term, keeps you in control.
