About Conversion

An ecommerce marketing agency that doesn't care what platform you're on

  • Platform-Agnostic

    Shopify, BigCommerce, Woo, Magento, headless

  • San Francisco, USA

    In-house team

Conversion is a full-funnel ecommerce marketing agency headquartered in San Francisco, working with DTC and B2B brands past $1M in revenue on Shopify, BigCommerce, WooCommerce, Magento, headless storefronts, and fully custom builds. We built our name as a Shopify Plus Partner, but most of the brands we scale today aren't on Shopify at all. That distinction matters. Most "ecommerce marketing agencies" are really Shopify agencies wearing a broader label: their playbooks, integrations, and reporting all assume one platform. We built a dedicated practice so brands on any stack get the same senior strategists, the same creative pipeline, and the same pay-on-results structure. Brands built natively on Shopify get the platform-specific version through our Shopify marketing agency service.

One team runs paid acquisition, retention and lifecycle, SEO, CRO, and marketplace expansion together, so every channel ties back to one P&L, one weekly report, and one strategist who owns the outcome. That covers Meta ads for ecommerce, Google Shopping, Performance Max, and search, email and SMS retention, and technical and content SEO. We treat marketplaces as a growth lever from day one. Amazon, Walmart, and TikTok Shop expansion get planned alongside your DTC roadmap, with Amazon marketing run by the same team so inventory, creative, and pricing stay aligned.

Why generic ecommerce marketing stalls

Five vendors, five priorities, no one owns the number

We audit every ecommerce marketing setup before taking it over. Brands past $1M in revenue hit the same three walls, regardless of platform.

  • Platform bias baked into the pitch

    Most "ecommerce marketing agencies" are Shopify shops in disguise: their case studies, integrations, and playbooks assume one platform. If you're on BigCommerce, WooCommerce, Magento, or headless, you get a watered-down version of their best work.

  • A fragmented vendor stack

    A paid media agency, an email freelancer, an SEO contractor, and a CRO consultant, each optimizing their own channel, none accountable for the number that matters. Weeks disappear in status meetings while tests wait to ship.

  • Marketplaces bolted on late

    Amazon, Walmart, and TikTok Shop get handed to a separate agency months after DTC is already scaling. Creative, pricing, and inventory fall out of sync, and the new channel cannibalizes the old one.

Frequently asked

Ecommerce marketing agency questions

What does an ecommerce marketing agency do?
An ecommerce marketing agency runs the demand and revenue side of your store end-to-end: paid acquisition (Meta, Google, TikTok Shopping), retention and lifecycle marketing (email/SMS), SEO and content, conversion rate optimization, creative production, and increasingly marketplace channels like Amazon and Walmart. A platform-agnostic agency does this the same way whether you run Shopify, BigCommerce, WooCommerce, Magento, or a headless build. The strategy doesn't change just because the cart software does.
How much does an ecommerce marketing agency cost?
For brands past $1M in revenue, expect $6K to $30K/month depending on channel mix, ad spend, and whether marketplace expansion is included, plus a performance component for qualifying brands. Full-scope engagements spanning paid, retention, SEO, CRO, and marketplace typically land $15K to $60K/month. Conversion offers a pay-on-results structure tied to incremental revenue. Ask for a scoped quote on your first call.
What's the minimum revenue to work with an ecommerce marketing agency?
Most capable agencies, including us, work best with brands doing $1M+ in trailing 12-month revenue. Below that, the fixed cost of a full team (strategist, media buyer, retention specialist, creative) outweighs the marginal lift, and we'll usually recommend a self-managed playbook or a narrower single-channel engagement instead.
What ecommerce platforms do you support besides Shopify?
BigCommerce, WooCommerce, Magento (1 and 2), headless builds (Next.js, Hydrogen, custom storefronts on a commerce API), and fully custom-coded stores. Our marketing strategy, reporting, and creative process are built to be platform-independent: the tactics adapt to each platform's checkout and catalog constraints, and the growth system stays the same. Our Shopify Marketing Agency service is purpose-built for brands natively on Shopify or Shopify Plus, with deep integration into Shopify-specific tools like checkout extensibility and the Shopify app ecosystem. If you're on Shopify, start with the Shopify Marketing Agency page; everyone else starts here.
How long does it take to see revenue growth?
Paid acquisition typically shows signal in 14 to 30 days. Retention and lifecycle revenue starts compounding in 4 to 6 weeks as flows mature. CRO wins usually land in 30 to 60 days. SEO is a 4 to 6 month build regardless of platform. Most clients see a measurable revenue lift by month 2 and a compounding trend by month 4 to 6.
Do you handle marketplace channels like Amazon, Walmart, or TikTok Shop?
Yes, and we treat it as a growth lever from day one. We manage Amazon Seller and Vendor Central, Walmart Marketplace, and TikTok Shop alongside your DTC channels, with shared creative and synced pricing and inventory so the new channel adds revenue without cannibalizing your own site.
What's included in a typical engagement?
A written 90-day plan, a dedicated senior strategist, execution across the channels you engage us for (paid, retention, SEO, CRO, marketplace, creative), weekly reporting on MER and contribution margin, and a monthly strategy review. Everything ships as documentation and dashboards you own.
Do you require a long-term contract?
No. We run month-to-month for most clients after an initial 90-day foundation period needed to build tracking, flows, and creative pipeline properly. Most clients move into our pay-on-results structure after that period, which further removes the incentive to lock you into a long contract.
How do you measure success across paid, retention, SEO, and CRO?
Blended MER (Marketing Efficiency Ratio), contribution margin, new-customer ROAS, and LTV:CAC, reported weekly across every channel in one dashboard. Per-channel metrics like email revenue share, organic sessions, and A/B test lift roll up into the same P&L view so you always know what's actually moving the number.
Can you take over from our existing agencies or freelancers without disruption?
Yes. Most new engagements start as a takeover. We audit existing accounts (ad platforms, ESP, GA4/analytics, SEO), preserve what's working, and migrate access over a 1 to 2 week transition window with no gap in active campaigns or flows.
Do you work with regulated industries like healthcare or supplements?
Yes. Healthcare and supplement/nutraceutical ecommerce brands are a core part of our client base, alongside DTC and B2B. We build claims-safe ad creative, compliant email content, and platform-approved marketplace listings for regulated categories.
What makes your pay-on-results model different from a typical retainer?
A flat retainer pays us the same whether your revenue grows or not. Our pay-on-results structure ties our fee to incremental revenue we generate, so the incentive is aligned with your P&L from the first invoice.
