The ecommerce marketing agency that makes paid channels pay for themselves
Google Ads, Meta, TikTok, marketplace ads, product feeds, creative, and email and SMS. One senior in-house team, one plan, and reporting that answers the only question that matters: did this make you money?

What does an ecommerce marketing agency do?
An ecommerce marketing agency plans, buys, and optimizes the channels that bring buyers to an online store and bring them back again. That covers paid search and Google Shopping, paid social on Meta and TikTok, marketplace and retail media ads on Amazon and Walmart, the product feed behind all of it, the ad creative those platforms consume, and the email and SMS flows that lift what each customer is worth. It is distinct from ecommerce SEO, which earns organic search demand rather than buying it, and from ecommerce development, which builds the store the traffic lands on. FactoryJet runs all three for US brands, as separate services with separate reporting, so you always know what each one returned.
Buying and building on the platforms your customers already use
Marketing, SEO, growth, and development are four different jobs
Plenty of agencies blur these together and then report on whichever one happens to look best that month. We keep them separate. Here is the honest map so you can pick the one you actually need.
Ecommerce marketing
Buying demand and owning the customer relationship: paid search and shopping, paid social, marketplace ads, feeds, creative, email and SMS. Results arrive in days and stop when the spend stops.
Ecommerce SEO
Organic rankings for collection and product pages. The compounding half of search.

Most brands end up with a media buyer over here, a feed guy over there, and an email freelancer who has never seen an ad account. Nobody owns the number. We do.

Creative testing →Feeds, tracking, and the unglamorous plumbing
Product titles written the way people actually search, correct product types and identifiers, supplemental feeds for the attributes your platform will not export cleanly, deduplicated conversion events, and purchase values that match reality. This is where a surprising share of shopping performance is decided, and it is the first thing we look at.
The 7 channels to turn on, in the order we recommend turning them on
You do not need all seven. You do need them in roughly this sequence, because each one performs better and reads more clearly once the one above it is healthy.
- Branded and shopping search
Start where demand already exists. Branded search protects the customers you have earned, and shopping search puts your product in front of people who typed the thing you sell.
- Non-branded shopping and Performance Max
Once the feed is clean and tracking is trustworthy, widen into cold shopping demand. This is where feed quality stops being a technical detail and starts being the campaign.
- Paid social for demand creation
Meta and TikTok reach people who were not looking for you. Creative carries the result here, so this step only makes sense once you can produce and test a real slate of angles.
- Retargeting, sized honestly
Retargeting always looks excellent and rarely creates demand. Keep it, keep it small, and never let its flattering numbers set the strategy for the whole account.
- Email and SMS retention
Welcome, cart, browse, post purchase, replenishment, and win back flows. This is the layer that makes everything above it viable, because it lifts what a customer is worth over time.
- Marketplace and retail media
Amazon, Walmart Connect, and TikTok Shop ads reach buyers already in checkout mode. Worth adding when your category has real search volume inside those platforms.
- Upper funnel and brand
YouTube, creators, and broad reach campaigns. These belong last, when the measured channels are healthy and you need a bigger pool of demand to keep scaling.
Ad platforms grade their own homework. We do not take their word for it.
Every platform will happily claim the same sale. Read those reports uncritically and you will scale the channel that harvested the order rather than the one that created it. Here is how we avoid that.
Platform metrics, held loosely
Useful for deciding what to change inside a campaign. Not useful for deciding whether a channel deserves more spend. We read them as diagnostics, never as a verdict.
Blended performance across everything
Total revenue against total spend across every channel. It cannot be gamed by attribution windows, and it is the number we hold ourselves to when we ask you to increase spend anywhere.
Contribution, after everything comes out
What is left once product, shipping, payment fees, and media are accounted for. A channel can look wonderful on revenue and still be quietly unprofitable. This layer catches that.
A note on attribution models. Google Ads data driven attribution spreads conversion credit across the interactions on a path instead of handing everything to the last click, which is a genuine improvement over last click. Google is also clear that the model needs a meaningful volume of conversions and interactions in the account before it has enough data to work from, so smaller accounts should treat its output with care. That is exactly why we keep the blended and contribution layers above it. Google Ads Help: about data driven attribution
From free channel audit to a program that scales, in four steps
No discovery theatre. The first thing we do is find out whether your numbers can be trusted, because everything after that depends on it.
Audit
Account structure, tracking accuracy, feed health, creative library, and retention flows. We find what is broken before we spend anything.
Fix the floor
Conversion tracking, feed remediation, and account structure first. Optimizing toward numbers that are wrong is the fastest way to waste a quarter.
Launch and test
Channels go live in a deliberate order with a creative test slate behind each one. Every test has a hypothesis and a read date.
Scale what returns
Concentrate spend where contribution is real, cut what is not working, and keep the next test slate ready before the current winner fatigues.
COMPARE
FactoryJet vs an ads-only shop vs a freelance media buyer vs an in-house hire

| FactoryJet | Ads-only agency | Freelance media buyer | In-house hire | |
|---|---|---|---|---|
| Paid search and shopping | Yes | Yes | Usually one platform | Depends on hire |
| Paid social creative testing | Yes | Often outsourced | Buying only | Depends on hire |
| Product feed engineering | Yes | Rarely | Rarely | Rarely |
| Marketplace and retail media ads | Yes | Sometimes | Rarely | Rarely |
| Email and SMS retention | Yes | Separate vendor | Separate vendor | Depends on hire |
| Landing pages and store fixes | Yes | No | No | Needs dev support |
| Conversion tracking audit first | Yes | Sometimes | Rarely | Sometimes |
| Reporting on contribution, not just ROAS | Yes | Channel metrics | Limited | Yes |
| Time to ramp | Yes | Weeks | Yes | Two to three months |
| You keep the ad accounts | Yes | Ask first | Yes | Yes |
6 things to check before hiring an ecommerce ad agency
Use this on us too. If we cannot answer all six clearly on the first call, you should be talking to somebody else.
- They audit tracking before they touch a campaign
If the first conversation is about creative and not about whether your conversion data is trustworthy, they are about to optimize toward numbers that are wrong.
- They report on blended performance, not just platform ROAS
Ask what happened to total revenue during their last engagement, not what the ad platform claimed. The gap between those two answers is the whole story.
- They own the product feed
Shopping performance is decided in the feed as much as in the bidding. An agency that treats the feed as your problem is handing you half a service.
- They produce creative in volume, with a system
Paid social is a creative testing business now. Ask to see how they generate angles and how they decide what wins, not just a reel of pretty assets.
- You keep the accounts
Your ad accounts, Merchant Center, analytics, and email platform stay in your name. No exceptions, no matter how it is framed.
- They will tell you when a channel is not worth it
An agency that has never recommended cutting a channel is either extraordinarily lucky or is optimizing for its own retention rather than your profit.
Ecommerce marketing agencies brands compare us with
There are good agencies in this space and pretending otherwise would be insulting. Here is where a few well known names fit, and where we fit.
A large independent performance marketing agency with deep retail media and marketplace practice. Strong fit for brands with enterprise scale spend and internal marketing teams to match.
A well regarded direct to consumer paid media shop with a rigorous forecasting framework, especially in the Shopify world. Excellent on acquisition, narrower on the store and marketplace side.
A recognized paid search and conversion optimization agency managing significant ad spend. Strong on ads and testing, lighter on feed engineering, marketplaces, and store development.
One senior in-house team running paid search, paid social, feeds, creative, marketplaces, and retention, with store development in the same building. Built for small and mid market brands rather than enterprise scale engagements.
Descriptions reflect each agency’s publicly stated positioning and are offered as a fair comparison, not as criticism. Every one of them is a reasonable choice for the right brand.

What does an ecommerce marketing agency do?
An ecommerce marketing agency plans, buys, and optimizes the channels that bring buyers to an online store and bring them back again. In practice that means paid search, shopping feeds, paid social, marketplace and retail media ads, creative production, and email and SMS. The agency owns the demand side of your revenue: which channels get spend, what the ads say, who sees them, and what each channel returns.
What is the difference between an ecommerce marketing agency and an ecommerce SEO agency?
A marketing or advertising agency buys attention. An SEO agency earns it. Paid work turns on and off with spend and gives you results in days. SEO compounds slowly and keeps paying after you stop. Most healthy stores run both. We keep them as separate services so you can see exactly what each one returns: paid lives on this page, organic lives on our ecommerce SEO page.
What is an ecommerce advertising agency?
An ecommerce advertising agency is the media buying half of ecommerce marketing. It builds and runs ad accounts on Google, Meta, TikTok, Amazon, and similar platforms, produces the creative those platforms need, manages the product feed behind shopping ads, and reports on what the spend returned. Some agencies stop at the ad account. We also handle the feed, the creative, and the landing experience, because an ad is only as good as what it lands on.
What is ecommerce development?
Ecommerce development is the work of building the store itself: the theme or storefront, the product catalog structure, checkout, payments, shipping logic, and the integrations that connect your store to inventory, accounting, and shipping systems. It is a build discipline, not a marketing one. FactoryJet does both, but they are separate services. Ecommerce development is covered on our ecommerce development page.
What does an ecommerce developer do?
An ecommerce developer builds and maintains the technical side of an online store. Day to day that looks like building theme templates and product page layouts, wiring payment and shipping providers, connecting the store to an ERP or inventory system, building custom checkout or subscription logic, and fixing the performance and bug issues that quietly lose orders. On a marketing engagement, developers matter because landing pages, tracking, and feed structure all sit in their territory.
What are the top 5 ecommerce companies?
By worldwide sales volume the usual names are Amazon, Alibaba, JD.com, Pinduoduo, and Walmart. In the United States the list is generally Amazon, Walmart, Apple, eBay, and Target. Those are marketplaces and giant retailers, not agencies, and they matter to you for one reason: Amazon and Walmart are also ad platforms, so the same companies you compete with are places you can buy demand.
Do I need an ecommerce marketing agency or a general digital marketing agency?
Pick the specialist if your revenue comes from a catalog. Ecommerce has problems a generalist rarely touches: product feeds, catalog structure, promotions, returns, margin by SKU, marketplace listings, and repeat purchase behavior. A generalist optimizing for leads will optimize the wrong thing on a store. Ask any agency to explain how they would handle your feed and your margin data. The answer tells you quickly.
Which platforms do you work with?
Shopify and Shopify Plus, Magento and Adobe Commerce, BigCommerce, and WooCommerce on the store side. On the ad side, Google Ads and Merchant Center, Meta, TikTok, Pinterest, Microsoft Advertising, Amazon Ads, and Walmart Connect. On the retention side, Klaviyo, Shopify Email, and Attentive.
Channels & creative
Which paid channel should an ecommerce brand start with?
Almost always branded and shopping search on Google first, because that captures demand that already exists and gives you a clean read on your true baseline. Then broaden into non-branded shopping and Performance Max, then paid social for demand creation. Starting with paid social when your search coverage is leaky is the single most common way brands waste spend.
Do you run Google Shopping and Performance Max?
Yes, and we treat the product feed as part of the campaign rather than an afterthought. Google Performance Max campaigns reach across YouTube, Display, Search, Discover, Gmail, and Maps from one campaign, and Google uses your feed, creative assets, audience signals, and conversion values to decide what to show. That means feed quality and asset quality are the levers you actually control, so that is where we spend our time.
Do you manage Meta and TikTok ads?
Yes. Meta and TikTok are demand creation channels: you are interrupting someone, not answering them, so the creative carries most of the weight. We run structured creative testing on hooks, formats, and offers, keep a rolling library of winners, and refresh before fatigue shows up in the numbers rather than after.
Do you run Amazon, Walmart, and TikTok Shop advertising?
Yes. Marketplace ads behave differently from site ads: the shopper is already in buying mode, the listing is the landing page, and your competitors sit on the same screen. We coordinate marketplace ads with your own site so product listings, promotions, and creative stay consistent instead of quietly undercutting each other.
What is retail media and does my brand need it?
Retail media is advertising you buy inside a retailer or marketplace, like sponsored product placements on Amazon or Walmart. You need it if a meaningful share of your category demand already searches inside those platforms rather than on Google. If you sell a considered, brand-led product that people search for by name, your own channels usually come first.
Do you produce the ad creative or do we?
We produce it. Static, motion, and user generated style creative, built from a running list of angles we test rather than one hero concept everyone hopes will work. If you already have an in-house studio we plug into it and supply the briefs, the testing structure, and the read on what is winning.
How much creative does a paid social account actually need?
More than most brands expect and fewer polished pieces than they think. What matters is variety of angle, not volume of assets. A small set of genuinely different hooks, offers, and formats beats a large set of the same idea in different colors. We keep a rolling test slate so there is always a next concept ready when a winner fatigues.
Is email and SMS part of ecommerce marketing or is that separate?
It is part of it, and it is usually the fastest thing to fix. Paid brings a buyer once. Flows bring them back. Welcome, browse abandonment, cart abandonment, post purchase, replenishment, and win back sequences do the quiet compounding work that lifts what each customer is worth over their lifetime, which is what makes paid acquisition sustainable at all.
Do you handle the product feed and Merchant Center?
Yes. Feed work is unglamorous and it is where a lot of shopping performance is decided: titles that match how people search, correct product types and GTINs, clean images, accurate availability attributes, and supplemental feeds for the fields your platform does not export cleanly. A great bidding strategy on a bad feed still loses.
Can you improve the landing pages our ads point to?
Yes, and we usually have to. Sending paid traffic to a generic collection page is a common leak. We build and iterate on the pages behind the ads so the promise in the creative matches the first screen the visitor sees. Deeper conversion rate work across the whole site sits with our ecommerce growth service.
Measurement & reporting
How do you measure whether the marketing is working?
Three layers. Platform metrics tell us how a campaign is behaving. Blended numbers across all channels tell us whether the whole program is working. Contribution, meaning what is left after product, shipping, payment fees, and media come out, tells us whether it is worth doing at all. If a channel looks good in the platform and bad in the blended view, we trust the blended view.
What is ROAS and why do you say it is not enough on its own?
ROAS is return on ad spend: revenue attributed to a channel divided by what you spent there. It is useful and it is easy to flatter. Retargeting and branded search will always look excellent because they harvest demand other channels created. Judge the program on blended performance and on contribution, then use channel ROAS to decide where the next dollar goes inside that program.
How do you handle attribution when every platform claims the same sale?
We expect the double counting and plan for it. Platform reporting is directional, not truth. Google Ads data driven attribution distributes credit across the interactions on a conversion path instead of giving everything to the last click, and Google notes it works best once an account has enough conversion volume to model, so smaller accounts need extra caution. On top of that we watch blended performance, run holdouts where the spend justifies it, and ask new customers how they found you.
Do you set up GA4 and conversion tracking?
Yes, and we audit it before we touch a campaign. Broken or duplicated conversion events are the most common reason an account looks unfixable. We verify server side and browser side events, deduplicate them, confirm purchase values match the platform, and only then start optimizing.
What does reporting look like and how often do we get it?
A live dashboard you can open any time, a short written note each week on what changed and why, and a longer monthly review that covers what we learned, what we are killing, and what we are trying next. Plain language, no vanity charts, no slide decks built to impress rather than inform.
How long before we see results from paid ads?
Tracking fixes and account structure cleanups can move numbers within the first few weeks. Creative testing needs a full cycle of learning before you can trust it. Retention flows compound quietly from the moment they launch. The honest answer is that early signal comes fast and durable signal takes a quarter.
What happens if a channel is not working?
We say so and we cut it. There is a version of this business where an agency keeps a losing channel alive because it is billable. We would rather concentrate spend where it returns and tell you plainly that something did not work, because the alternative gets found out anyway.
Working together
What happens in month one?
Week one is diagnosis: account structure, tracking accuracy, feed health, creative library, and retention flows. Week two you get a prioritized plan with the reasoning attached. Weeks three and four we ship the highest impact fixes, launch the first test slate, and set the reporting rhythm. You should be able to see what changed and why by the end of it.
What determines the scope of an ecommerce marketing engagement?
Scope is driven by how many channels you want live, how large and how complex your catalog is, how much creative volume the channels need, whether marketplaces are in play, how much tracking and feed remediation the account needs first, and whether landing page work is included. We map those factors to your goals and put the scope in writing before anything starts.
Should we hire an agency or build an in-house team?
In-house wins on context and availability. An agency wins on breadth and on pattern recognition across many accounts. The practical answer for most small and mid sized brands is an agency running the channels while one internal owner holds strategy and brand. Bringing it in-house makes more sense once your spend is large enough to justify a full specialist per channel.
Who will actually work on our account?
FactoryJet senior in-house specialists. The people in your kickoff are the people in your ad accounts. We do not run a model where a senior team sells the work and a junior pod delivers it, which is a large part of why clients stay.
Do we have to sign a long contract?
No. We work on short rolling terms and earn the renewal with results. If a bigger build is bundled into the engagement we scope that separately and clearly up front so nothing is a surprise later.
Do you work with brands that already have an agency?
Often, yes. Sometimes that starts as a second opinion on account health, sometimes it is a specific channel your current partner does not cover, like marketplaces or feed management. We will tell you honestly if your existing setup is in good shape, because pretending otherwise is a bad way to start a relationship.
What size ecommerce brands do you work with?
Mostly US small and mid market brands: stores that have proven the product and are ready to put real weight behind acquisition, through to established brands scaling across several channels and marketplaces. We size the engagement to your stage rather than pushing one standard package at everyone.
Do we own our ad accounts and data?
Always. We work inside your accounts, your Merchant Center, your analytics, and your email platform. If we ever part ways you keep every account, every audience, every creative asset, and every piece of historical data. Agencies that hold accounts hostage are telling you something about their confidence in the work.
How do we get started?
Send us your store URL and your email and we will run a free channel audit: account structure, tracking, feed, creative, and retention flows, with a prioritized plan you keep whether or not you work with us. No long sales cycle and no pressure.
