For ecommerce brands doing $100K–$3M in revenue
Most ecommerce brands aren't short on marketing activity. They're short on a system that educates buyers and connects the channels. That's where the revenue gap lives.
The problem
The content exists. There's a product page, maybe some articles, an email list that gets used occasionally. Each piece does something. None of it adds up.
The gap is usually in two places.
Brand trust. Buyers can find the products. What they can't find is a reason to trust you specifically — the story, the point of view, the sense that someone real is behind this. Without it, you're one of ten tabs they have open.
The connection between channels. A good article that doesn't feed email. Email that isn't saying what the ads say. Ads driving clicks to pages that can't close. Each channel running on its own means every dollar works harder than it needs to.
The fix
The difference is whether everything is working toward the same thing.
SEO that reaches people while they're still asking questions, and earns their trust before they're ready to buy. Email that makes the brand feel real, explains the products, and keeps people engaged. Landing pages that close because they've already answered the questions the buyer had. A brand story that makes you memorable instead of interchangeable.
When those pieces connect, ad costs drop. Conversion goes up. Buyers who were almost ready actually buy. The ones who buy come back.
I've been building this for a specialty ecommerce retailer for over four years. The business went from $400K to $2.7M. That's not an accident of product or timing. It's what happens when the full system is running.
What you get
These aren't separate services. They're the parts of one system, built to connect and compound.
Content Strategy & CRO
The backbone of the system. Articles that build trust and rank, landing pages that convert, product pages that close. Content strategy determines whether everything else compounds.
17% average order value increase through CRO and landing page optimization.
SEO & Search Everywhere
Search isn't just Google anymore. Technical SEO, keyword targeting, and content built to surface wherever your buyers are looking — search engines, AI tools, YouTube, and beyond. Traffic that's already looking for what you sell.
Grew organic keywords from 9,000 to 40,000+.
Email Marketing (Klaviyo)
Full email programs built from zero. Flows, campaigns, segmentation, list growth. Email becomes a revenue channel, not a backlog item.
Built a Klaviyo program from zero to $453K in attributed revenue in the first six months. Top 10% of platform operators.
Website Development
I lead the build and bring in a designer and developer to execute it. Brand story, page structure, product presentation. The website is the foundation everything else runs on.
Meta Ads
Campaign strategy, creative direction, audience building, retargeting. Connected to the rest of the system so every dollar works harder.
Strategy & Reporting
Clear attribution and honest reporting. You know what's working, what's not, and what to do next. No dashboards full of vanity metrics.
The numbers
The average ecommerce brand grows around 8–9% a year. What you see below came from running every channel for a specialty ecommerce retailer — work I'm still doing today. The growth is in the method.

The paid ads that drive much of the site's revenue convert because of the brand story, landing pages, and product experience built alongside them. The system is the asset.
The brands I work with are building something real. They have a product people actually want, a story worth telling, and usually someone who knows their customer better than any agency ever will. They just need the marketing to catch up. That's the work I'm here for.

How to start
Fill out the form below. Tell me about your business and where you're stuck.
I'll review it and get back to you within 48 hours.
We get on a call. I'll ask questions, look at your setup, and tell you exactly what I'd do first.
We pick a starting point. Retainer for ongoing work, a defined project to start smaller, or for the right fit, a profit-share arrangement. Whatever makes sense for where you are.
No pressure. Just a conversation about your marketing.
Common questions
Can one person really handle all of this?
Yes. I run the system and own every channel: SEO, email, content, Meta ads, CRO. When a project needs it, I bring in people who are genuinely good at what they do: a designer and developer, a writer, a PPC specialist, and someone I work closely with on growth tactics. You still get one person who owns the strategy and makes sure everything connects.
How do I know your results will transfer to my business?
They're proof of a process, not a single lucky outcome. Connected channels that compound work across ecommerce verticals. I'd rather show you than tell you. A defined project is a good way to see the approach before committing to anything ongoing.
What does this cost?
Depends on scope. Retainers are for businesses that want full-stack marketing run on an ongoing basis. Project work is for a specific deliverable: email setup, SEO audit, content strategy, site build. Either way, it costs less than an agency and less than a full-time hire. We'll talk numbers once I understand your situation.
What if I just need help with one channel?
Start there. Project work is a real option and a low-commitment way to see how I work. Fair warning: once you see what happens when channels actually connect, the single-channel thinking tends to go away.
Are you just using AI to do the work?
AI is part of how I work. I used to write everything myself: every email, every article, every page. Now AI drafts faster, but the strategy, the judgment, and the final call are still mine. The results you're looking at came from years before any of these tools existed.
What does the first 90 days look like?
The first month is mostly diagnostic. I look at everything — analytics, email, site, ads, existing content — and figure out where the biggest gaps are. Almost always, a content strategy is the first thing we build. It's the backbone everything else runs on. By month two something is built and running. By month three the system is taking shape and we're measuring what's working.
About
I'm Marc St. John, a marketer and writer based in Columbus, Ohio.
For over four years I've led the marketing for a specialty ecommerce retailer. It came in stages. Content strategy and SEO first, then the website, built alongside a designer and developer. In the last year I added Klaviyo email and Meta ads to what I run directly. Both took off fast: email hit $453K in attributed revenue in the first six months. The business went from $400K to $2.7M.
Before marketing, I was an English teacher. Every day: original content for over 100 people, progress measured against clear objectives, constant feedback and iteration. The feedback loop is identical.
The other thing that shaped how I work: I spent my whole life playing baseball. Hitting, specifically. High pressure, public, and the feedback is immediate. You barrel it or you don't. What it taught me is to refine the approach, trust the work, and let the numbers tell the truth. Marketing works the same way.
