Quick answerWhat does an ecommerce growth agency do?

An ecommerce growth agency runs every channel that drives store revenue as one system: paid ads, email and SMS, SEO, conversion rate optimization, and increasingly AI automation. Instead of hiring separate specialists, you get one accountable team that ties spend to revenue, tests continuously, and reports on profit. FactoryJet does this across Shopify, Magento, BigCommerce, and WooCommerce for US brands.

Why it matters

Why ecommerce growth is worth investing in

Online shopping is still climbing, and the brands that compound the small levers pull away. Three numbers that frame it.

What we run

Full-funnel ecommerce marketing, under one roof

Most agencies do one thing. Growth needs all of them working together. Every channel is a service we run in-house, and each links to how we deliver it.

Financial Telemetry

The 4-Pillar Ecommerce Profit Equation: Beyond Vanity ROAS

Scaling ad spend without unit economic discipline destroys operating cash flow. We manage your growth portfolio across four fundamental financial metrics:

1. Marketing Efficiency Ratio (Blended MER) > 4.0x

Rather than relying on isolated channel platform attribution, we calculate Blended MER (Total Top-Line Revenue divided by Total Marketing Ad Spend across all channels). This measures true enterprise profitability and ensures paid acquisition lifts net cash flow.

2. Net Contribution Margin (NCM) Modeling

We map your gross margin, payment gateway fees, pick-pack-and-ship fulfillment expenses, and returns allowance to establish the exact breakeven Customer Acquisition Cost (CAC) for every SKU and product category in your catalog.

3. 60-Day & 90-Day LTV:CAC Expansion (4:1 Ratio Target)

Acquiring a customer at breakeven is a winning strategy only when your post-purchase email, SMS, and loyalty engine reliably produces repeat purchases within 60 days. We engineer retention flows that turn single-order buyers into high-LTV brand advocates.

4. Server-Side First-Party Attribution & Meta CAPI Signal Recovery

With browser cookie deprecation and iOS privacy signal loss, client-side tracking drops up to 30% of conversion events. We deploy server-side Meta Conversions API (CAPI) and Google Tag Manager server containers to restore 95%+ event match quality.

Omnichannel Architecture

How Paid Media, Retention, CRO & AI Search Work as One Engine

Single-channel tactics fail because modern consumers interact across six touchpoints before purchasing. Here is how our senior in-house team synchronizes your growth stack:

Paid Media (Meta Advantage+, Google PMax & TikTok Shop Ads)

We deploy high-converting UGC creative frameworks, modular video hooks, and value-based bidding (tROAS) targeting high-intent in-market shoppers across Google Search, Shopping, YouTube, Instagram Reels, and TikTok Shop.

Klaviyo Lifecycle Retention & RFM Predictive Segmentation

We build automated 12-stage email and SMS customer journeys, including dynamic welcome series, high-intent cart abandonment triggers, price drop alerts, VIP early access drops, and predictive replenishment flows based on SKU consumption cycles.

Scientific Conversion Rate Optimization & Sub-Second Checkout

We execute multivariate A/B testing on product detail pages (PDPs), sticky add-to-cart bars, in-cart bundle builders, trust badges, and 1-click Shop Pay checkout workflows, lifting session conversion rates from 1.8% to 3.2%+.

Organic E-Commerce SEO & Generative AI Search Optimization (GEO)

We structure collection pages, product schemas, and buying guides to dominate traditional Google rankings and capture prominent citations in ChatGPT, Perplexity, and Google AI Overviews.

Execution Methodology

The 90-Day Compounding Ecommerce Growth Sprint Roadmap

Iterative UGC ad creative sprint (15+ angles/hooks per month), Google Performance Max asset group segmentation, collection page SEO content optimization, in-cart bundle testing, and SMS list acceleration.

The playbook

The 6 growth levers we pull for ecommerce brands

Acquisition that pays back

Paid social and search tuned to contribution margin, so scaling spend does not quietly kill your profit.

Organic and AI search

Ecommerce SEO plus answer-engine optimization so buyers find you in Google and in ChatGPT.

Conversion rate optimization

Structured testing on product, cart, and checkout to lift revenue without spending a dollar more.

Marketplace expansion

Amazon, Walmart, and TikTok Shop set up and managed as extra revenue channels, not distractions.

AI automation

Agents that handle support, product data, and reporting so your team spends time on growth, not admin.

Before you hire anyone

6 things to look for in an ecommerce agency

Use this as a checklist, whether you talk to us or anyone else.

Reports on profit, not clicks

Ask how they define success. If the answer is impressions or ROAS alone, keep looking.

Owns more than one channel

Single-channel shops optimize their slice while your overall revenue stalls.

Senior people on your account

Confirm who actually does the work, not just who shows up to sell you.

Transparent, scoped engagements

No mystery retainers. You should know what you get and what happens next.

Real ecommerce experience

Platform knowledge of Shopify, Magento, and checkout matters more than generic marketing.

No long lock-in

Good agencies earn the renewal every month. Be cautious of year-long contracts up front.

The landscape

Named ecommerce agencies brands compare us with

Plenty of good growth agencies exist. Here is where the known names fit, and where we fit.

Common Thread Collective

A respected DTC growth shop with a strong paid-media and forecasting framework in the Shopify world. Excellent at paid acquisition, narrower on the full stack.

Power Digital

A broad cross-channel growth partner for brands that want wide coverage. A bigger-agency structure, which can mean more layers between you and the work.

Disruptive Advertising

A recognized PPC and conversion-optimization agency managing serious ad spend. Strong on ads and CRO, lighter on store builds and marketplaces.

Where FactoryJet fits

One senior in-house team running ads, email, SEO, CRO, the store build itself, marketplaces, and AI, sized for SMBs rather than enterprise retainers.

FREQUENTLY ASKED QUESTIONS

Ecommerce growth agency FAQs

The questions US ecommerce founders actually ask us. Straight answers.

The basics

What does an ecommerce growth agency do?

It runs every channel that drives store revenue as one system: paid ads, email and SMS, SEO, conversion optimization, and AI automation. Rather than managing separate specialists, you get one accountable team that ties spend to revenue and reports on profit.

What is ecommerce marketing?

Ecommerce marketing is how an online store attracts visitors and turns them into repeat buyers. It spans paid ads, email and SMS, SEO, social, and conversion optimization. The goal is not traffic for its own sake, it is profitable, repeatable revenue from the channels that pay back.

How do you grow an ecommerce business?

You grow revenue on three fronts at once: get more of the right traffic (ads and SEO), convert more of it (CRO and store speed), and keep more customers buying (email, SMS, loyalty). We audit which lever is weakest for you and fix that first for the fastest return.

Which channels do you manage?

Paid ads (Google, Meta, marketplaces), email and SMS, ecommerce SEO, conversion rate optimization, and AI search. We also set up and manage marketplace selling on Amazon, Walmart, and TikTok Shop when they fit your brand.

What makes FactoryJet different from a single-channel agency?

Single-channel agencies optimize their slice while your overall revenue can still stall. We own the full funnel and the store itself, so ads, email, SEO, CRO, and site changes move together. One team, one number to grow.

Services & channels

Do you offer ecommerce PPC and advertising management?

Yes. We run paid search, paid social, and marketplace ads as a full ecommerce advertising service, managed to blended ROAS and contribution margin. You get transparent reporting on what each dollar returns, not just impressions and clicks.

Do you do ecommerce email marketing?

Yes. Email and SMS are usually the fastest profit lever for an existing store. We build welcome, abandoned-cart, post-purchase, and win-back flows in Klaviyo or Shopify Email, then run campaigns that lift repeat revenue.

Can you help with ecommerce SEO too?

Yes, ecommerce SEO is one of our core services. We optimize category, product, and collection pages so buyers find you in Google, and we optimize for AI search so you get surfaced in ChatGPT and Google AI Overviews.

What are the best AI tools for ecommerce?

The most useful today are AI for product content and merchandising, AI-driven email and ad creative, AI support agents, and AI search optimization. We help you pick the few that fit your stack and build custom AI agents where an off-the-shelf tool falls short.

Do you build or redesign the store as well?

Yes. When the store itself is the bottleneck we handle builds, redesigns, and replatforming on Shopify and Magento, including headless commerce. Growth marketing and development under one roof means fixes ship without vendor hand-offs.

Do you sell on Amazon, Walmart, or TikTok Shop?

Yes. We set up and manage marketplace selling on Amazon, Walmart Marketplace, and TikTok Shop as additional revenue channels, coordinated with your site so product pricing, inventory, and brand stay consistent.

Can you use AI to automate our marketing and operations?

Yes. We build AI agents that handle customer support, product data, reporting, and repetitive ops, so your team spends time on growth instead of admin. This is a core focus, not a bolt-on.

What is B2B ecommerce and do you support it?

B2B ecommerce is selling to other businesses online, with features like account-based pricing, quotes, and bulk ordering. Yes, we build and grow B2B stores on platforms like Shopify Plus and BigCommerce B2B, alongside your direct-to-consumer channels.

What is Marketing Efficiency Ratio (MER) and why is it superior to platform ROAS?

Platform-reported ROAS (in Meta Ads Manager or Google Ads) often takes double-credit for organic conversions and ignores customer acquisition costs. Marketing Efficiency Ratio (Total Net Revenue divided by Total Ad Spend) measures true blended business profitability, ensuring ad spend scales without eroding your bottom line.

How do you combat post-iOS 14 ad signal loss and attribution inaccuracies?

We implement server-side conversion tracking via Meta Conversions API (CAPI), Google Enhanced Conversions, and first-party data capture. This restores 95%+ event matching quality and allows machine learning bidding algorithms to optimize toward high-value repeat buyers.

How does conversion rate optimization (CRO) interact with customer acquisition costs?

Lifting your store conversion rate from 1.5% to 2.5% effectively cuts your customer acquisition cost (CAC) by 40% on every ad dollar spent. CRO creates operating utilize that allows you to outbid competitors and scale ad budgets profitably.

What is RFM customer segmentation in Klaviyo email marketing?

RFM analyzes Recency, Frequency, and Monetary value across your customer database. We build targeted VIP reward flows for high-value champions, automated replenishment triggers for predictable consumables, and aggressive win-back flows for churning buyers.

How do you structure product bundles and threshold upsells to increase Average Order Value (AOV)?

We engineer dynamic in-cart progress bars (e.g. "Add $15 for Free Shipping"), post-purchase 1-click upsells in checkout, and volume tiered bundle discounts (Buy 2 Get 10% Off, Buy 3 Get 20% Off), lifting site-wide AOV by 18% to 32%.

How do AI search citations in ChatGPT and Perplexity drive e-commerce revenue?

High-intent consumers increasingly use AI engines to research product comparisons and buying recommendations. By structuring your store content with deep schema, objective comparison tables, and verified reviews, your brand becomes the direct quoted answer in AI responses.

Working together

How much does an ecommerce agency cost?

It depends on the channels you need and the stage of your store. Rather than a fixed package, we scope the work to your goals and share a clear quote, so you only invest in what will actually move revenue. Ask for a free audit and we will size it with you.

How long until I see results?

Quick wins from email flows and paid-ad fixes often land in the first 30 to 60 days. SEO and CRO compound over three to six months. We prioritize the fastest-payback work first so early momentum funds the longer plays.

Do I have to sign a long contract?

No. We work on short, rolling terms and earn the renewal each month with results. If a longer commitment makes sense for a big build, we scope it clearly up front so there are no surprises.

Who will actually work on my account?

FactoryJet’s senior in-house team. The specialists in your kickoff are the ones doing the work, not a sales pod handing you to offshore juniors. That is a deliberate choice and a big part of why clients stay.

What size businesses do you work with?

Mostly US small and mid-market ecommerce brands, from stores doing their first serious growth push to established brands scaling past seven and eight figures. We scope the engagement to your stage rather than forcing one package on everyone.

How do you report on performance?

You get a live dashboard tied to revenue and contribution margin, plus a plain-language monthly review of what we did, what it returned, and what is next. No vanity metrics dressed up as progress.

How do we get started?

Request the free growth audit with your store URL and email. We come back with findings and a suggested 90-day plan, then you decide if you want us to run it. No pressure, no long sales cycle.
