How to vet an ecommerce marketing agency

1. Make them work in contribution margin, not revenue. Revenue targets are easy to hit by discounting and buying unprofitable traffic. Ask each candidate to model against contribution margin after cost of goods, shipping and payment fees. An agency that cannot or will not work in those terms is optimising a number that does not pay your bills.
2. Ask what they will do with the product feed. For most stores the feed drives more revenue than the ad copy does. Ask specifically how they audit titles, attributes, images and availability, and how often. Feed quality is unglamorous, invisible in a pitch deck, and one of the largest levers available in ecommerce marketing.
3. Check they can touch the site, not just the ads. Category pages, filters, internal search and product page structure decide whether traffic converts. Ask whether the scope includes site and merchandising recommendations, who implements them, and whether the agency has worked on your platform before. Ads pointed at a weak store make the store's weakness more expensive.
4. Agree the attribution model before month one. Platform-reported figures, analytics figures and your own order records will disagree. Decide in advance which source is the scoreboard, and reconcile against actual orders monthly. Engagements that skip this step spend the second quarter arguing about numbers instead of improving them.

What the phrase actually covers

Ecommerce marketing services usually bundle five things that could be bought separately. Paid acquisition across search, shopping and social. Organic search, which for a store means category and product page structure, and the technical work that lets search engines see the whole catalogue. Feed management, meaning the product data that powers shopping surfaces. Lifecycle marketing through email and messaging, which is often the highest return channel and the most neglected. And conversion work on the site itself.

Google publishes its own guidance for ecommerce sites covering how product data should be structured and how a store should be organised for crawling and indexing, and it is a useful yardstick in a sales conversation. Ask whether the agency's proposal touches structured product data, canonical handling for variants and out-of-stock behaviour. Those three appear in the documentation and are absent from most pitches, which makes them an efficient test of whether a candidate has read the material or is describing it.

The economics that decide whether an agency is worth it

Three numbers govern the decision and most stores do not have them ready. The contribution margin on an average order after goods, shipping, payment fees and returns. The share of orders that come from repeat customers, which decides how much you can afford to pay for a first order. And the payback period you can finance, since a business that must recover acquisition cost inside a month runs a different strategy from one that can wait two quarters.

Bring those numbers to the first call. They convert a vague conversation about growth into a specific one about what cost per order is acceptable and what volume that supports, and they immediately reveal which agencies think in those terms. A candidate who redirects the conversation back to revenue multiples and away from margin is telling you how it intends to be measured.

Where ecommerce engagements usually go wrong

The most common failure is spending on acquisition while the site converts badly, which makes every channel look expensive and hides where the actual problem is. The second is neglecting retention: stores that pour budget into first orders while sending two emails a month are paying full price for every customer repeatedly. The third is a feed nobody owns, where titles and attributes drift, products go out of stock without the feed knowing, and shopping performance decays for reasons the monthly report never surfaces.

A fourth, subtler failure is measurement drift. Platform-reported returns tend to flatter, and an engagement judged on them can look healthy for a year while the bank balance disagrees. Reconcile against real orders every month from the start. It costs an hour and it is the only reliable defence against a report that is technically accurate and practically wrong.

Questions people actually ask

What do ecommerce marketing services cost?

Pricing tends to follow one of three shapes: a flat retainer, a share of ad spend, or a hybrid with a base fee plus performance element, often with a minimum spend requirement. The headline fee matters less than what it includes. Confirm whether creative production, feed management, email and site work are inside the scope or billed separately, because those four are where quotes diverge most.

Should I hire specialists per channel or one agency?

One agency is simpler to manage and makes cross-channel budget decisions easier. Specialists usually go deeper in their channel. A common middle path is one agency for paid acquisition and feed, with specialist help for lifecycle email, since email skill and paid media skill rarely sit in the same person.

How long before an ecommerce agency proves itself?

Structural fixes and wasted spend removal show inside the first month. Creative and offer testing needs two to three months to produce conclusions. Organic search work on category structure takes two to three quarters. Judge the first ninety days on whether the diagnosis was right and the tests were run, not on whether revenue has already moved.

What should be in the contract?

Ownership of the ad accounts, the analytics and search console properties, the product feed and all creative produced. A defined scope by channel. A monthly reporting format agreed in advance, including the reconciliation source. A notice period you can live with. And clarity on who holds any tooling subscriptions, since those sometimes leave with the agency and take historical data with them.
