Convert more of the traffic you already have.
Research-led CRO for Shopify - PDP, cart, and checkout as a compounding system.
Santa Monica studio · Shopify-native CRO
- Research before redesign
- Shopify-native CRO
- Test, learn, compound
Ecommerce CRO turns more visitors into buyers - and more buyers into higher AOV - through research, hypotheses, and disciplined testing. Propeller runs it inside the same Shopify system as design, build, and growth.
What's broken
- Traffic is expensive. Leaks in PDP, cart, and checkout are quiet.
- Opinions replace research.
- Tests ship without a system - so nothing compounds.
How we fix it
Research → hypothesis → test → learn. Across PDP, collections, cart, and checkout.
Shopify-native. Evidence first. No vanity lifts.

Why Propeller
Most “CRO agencies” optimize in isolation from the storefront team. Propeller runs ecommerce CRO inside the same commerce system as Shopify design, development, and growth - so winning tests become permanent architecture, not abandoned experiments.
We prioritize money paths: PDP clarity, offer hierarchy, mobile cart and checkout friction, trust, and speed - ranked by revenue exposure. A/B testing only starts after the diagnosis is honest.

How it works
Align
We clarify the CRO goal, constraints, and what success looks like in revenue - not vanity metrics.
Diagnose
We audit the experience, stack, and growth system against what ambitious brands actually need.
Build
Senior team ships the work: storefront, flows, campaigns, or technology - without agency theater.
Prove
We measure what moved, then compound. Commerce is a system, not a launch party.

Objections
- Do you guarantee a conversion lift?

FAQ
What does an ecommerce CRO agency actually fix first?
Money paths: PDP clarity, offer hierarchy, mobile cart and checkout friction, trust, and speed - ranked by revenue exposure, not by taste. Propeller ships a roadmap, not a single button test.
Is this only for Shopify?
Shopify is our home turf. The CRO discipline applies broadly; our deepest leverage is on Shopify storefronts and paid landings.
How fast do CRO results show?
Quick wins can land in weeks; durable compounding needs a backlog and clean measurement against traffic volume.
What is a good ecommerce conversion rate?
It varies by category, AOV, and traffic quality - DTC Shopify stores often sit roughly in the low single digits, but “good” means improving against your own baseline and unit economics, not chasing a generic benchmark. We size opportunity before promising lift.
Do you run A/B tests or only redesign?
Both. We ship high-confidence fixes when friction is obvious, and run structured tests when traffic supports statistical power. Tools follow the hypothesis - Shopify-native experiments or dedicated platforms as needed.
How is Propeller different from a general digital marketing CRO team?
We are a commerce experience agency. CRO sits next to Shopify engineering, merchandising, and lifecycle - so wins stick in the theme and stack, not in a slide that expires when the campaign ends.
