The best ecommerce marketing agency for a Canadian store is one that knows your platform, plans channels around margin and inventory, tracks revenue honestly, and lets you own your accounts, data, and creative. Many agencies sell the same ad management package and a monthly traffic report. This guide explains which channels should be in scope, how agency models and pricing compare, how to read the reporting, and what to ask before you sign.
01. The Quick Answer: What to Look For
- Platform depth: Proven work on your platform, ideally as a certified partner.
- Margin-aware strategy: Channels judged on revenue and margin, not clicks.
- Honest reporting: One blended view, not each platform grading its own homework.
- Channel fit: Paid, email, SEO, and conversion work matched to your stage.
- Clear ownership: You own your ad accounts, data, and creative, with fair exit terms.
Why it matters: These five checks separate agencies that grow profitable revenue from agencies that grow ad spend.
02. Agency Models Compared
| Option | Best for | Typical cost model | Good when |
|---|---|---|---|
| Full-service ecommerce agency | Paid, email, SEO, and conversion work under one plan | Retainer plus ad spend | Lean teams that want one accountable partner |
| Channel specialist (PPC, email, SEO) | Deep expertise in one channel | Retainer, percent of spend, or project | A strong in-house marketer coordinates vendors |
| Commerce plus marketing agency | Marketing tied to store builds, CRM, and automation | Retainer or hybrid | Store, data, and campaigns need to work as one system |
| Freelancer or consultant | Audits, setup, and coaching | Hourly or project | Your team can run campaigns day to day |
| In-house marketer | Daily ownership and brand knowledge | Salary and tools | Steady volume and enough spend to justify the hire |
Why it matters: The right model depends on your ad budget, team skills, and how many vendors you can realistically coordinate.
03. Which Channels the Agency Should Cover
A complete ecommerce plan usually draws on paid search and shopping ads, paid social, email and SMS, SEO, and conversion work on the store. You do not need every channel at once. Start where intent and margin are strongest, then add. If you are weighing an SEO-only partner, read our guide to choosing an ecommerce SEO agency. For retention, see how Klaviyo email and SMS on Shopify fits the plan.
Why it matters: Spreading a small budget across every channel usually fixes none of them.
04. Strategy That Respects Margin and Inventory
Ask how the agency decides what to promote. Strong strategy uses product margin, stock levels, shipping cost, and repeat purchase rates, not only the products that convert best. Advertising a low-margin item, or one that is about to sell out, can grow revenue while shrinking profit. Recent platform changes, such as the Google Ads target bidding change, also reward agencies that feed the right goals into bidding.
Why it matters: Revenue is easy to buy. Profit is what the agency should be optimizing.
05. Tracking and Data Foundations
Before spending a dollar on ads, the agency should confirm that conversion tracking, product feeds, consent handling, and analytics are accurate on your Shopify store. Broken tracking quietly wastes budget because bidding systems learn from bad signals. Our guide to marketing attribution with Shopify and HubSpot shows how to connect ad spend to customers and revenue.
Why it matters: Ad platforms optimize toward whatever data you give them, so bad data buys bad results.
06. Reporting That Shows Real Revenue
Insist on a blended report: revenue, orders, average order value, new versus returning customers, conversion rate, and total marketing spend against revenue or margin, split by channel. Platform-reported return on ad spend is useful for tuning but unreliable as proof, since several platforms can claim the same order. Confirm that you have admin access to every ad account and to analytics from day one.
Why it matters: What is measured honestly gets improved, and what is self-reported gets flattered.
07. How Pricing and Ad Spend Work
Agencies typically charge a monthly retainer, a percentage of ad spend, a fixed-scope project fee, or a hybrid. Ad spend itself is paid to the ad platforms and is separate from the agency fee, so every proposal should show both. Percentage-of-spend models can reward spending more, so ask how the agency is motivated to spend less when that is the right call. Favor a short initial term with clear exit rights.
Why it matters: Understanding the fee model tells you what the agency is rewarded for.
08. Red Flags to Avoid
Guaranteed returns, reporting that stops at platform-reported return on ad spend, ad accounts held in the agency's name, long lock-in contracts, no named people on your account, and strategy that ignores your margins are all signs to walk away. Be wary of agencies that cannot show relevant ecommerce work or explain their own tracking setup.
Why it matters: The cost of the wrong agency is wasted ad spend and months of lost momentum, not just fees.
09. Questions to Ask Before You Sign
Ask how success will be measured in the first 90 days, who will work on your account, how budget is split across channels, how they handle your platform, what you own at the end, and how they report on margin. Ask for examples from Canadian ecommerce clients. If you also sell to trade buyers, see our guide to choosing a B2B marketing agency.
Why it matters: The answers show whether you are buying a partner or a package.

12. Frequently Asked Questions
What does an ecommerce marketing agency do?
An ecommerce marketing agency plans and runs the channels that bring shoppers to your store and bring them back: paid search and shopping ads, paid social, email and SMS, SEO, and conversion work on the store itself. A good one ties each channel to orders, revenue, and margin, not just clicks.
How much does an ecommerce marketing agency cost in Canada?
Agencies usually charge a monthly retainer, a percentage of ad spend, a fixed-scope project fee, or a hybrid. Ad spend is paid to the ad platforms and is separate from the agency fee. Ask for a written scope listing deliverables, hours, tools, and who does the work so you can compare proposals on substance, not only the monthly number.
Should I hire a full-service agency or specialists for each channel?
A full-service agency suits lean teams that want one accountable partner and shared data across channels. Channel specialists suit teams with a strong in-house marketer who can coordinate several vendors. Either way, the agency should share one reporting view so channels are judged on the same revenue numbers.
How long before an ecommerce marketing agency shows results?
Paid campaigns can produce data within weeks, but they usually need a few months of testing to stabilize. Email and SMS flows start earning once they are live and your list is segmented. SEO compounds over several months. Ask for leading indicators in the first 90 days and agree the targets in writing.
What should an ecommerce marketing report include?
Revenue, orders, average order value, new versus returning customers, conversion rate, and a blended view of marketing spend against revenue or margin, split by channel. Traffic, impressions, and platform-reported return on ad spend alone are not enough, because platforms tend to claim credit for the same sale.
Does the agency need to know Shopify?
Yes. Product feeds, tracking, checkout, theme speed, and apps all affect ad performance and conversion. If you sell on Shopify, choose an agency that is a certified Shopify partner and can fix feed, tracking, and theme issues itself instead of sending you a list of recommendations.
What are the red flags when hiring an ecommerce marketing agency?
Guaranteed returns, reporting that stops at platform-reported return on ad spend, ad accounts held in the agency's name, long lock-in contracts, no named people on your account, and strategy that ignores your margins and inventory. You should own your ad accounts, analytics, and creative at all times.
