Stop Wasting Paid Budget on a Broken Funnel.
You're buying expensive traffic into a store that leaks silently in PDP, cart, and checkout. Propeller fixes the money paths first - research-led CRO where it matters most.
Santa Monica studio · Shopify-native CRO · Average 15-25% CVR improvement
Ecommerce CRO converts more of the traffic you already have - and more buyers at higher AOV - through research, evidence, and disciplined testing. Propeller runs CRO inside the same Shopify system as design, build, and growth - so wins stick.
What's broken
- Traffic is expensive. Every visitor who doesn't buy is a leak - in PDP clarity, cart friction, or checkout trust. Most teams never measure or rank them.
- Stop wasting money on opinion-driven 'optimizations'. You're A/B testing button colors while your PDPs lack basic information and your checkout is three extra steps.
- Tests ship in isolation with no system - so you never compound wins. This quarter's test becomes next quarter's forgotten experiment. Revenue doesn't improve.
How we fix it
Research first. We audit money paths - PDP clarity, offer hierarchy, mobile cart friction, trust signals, and speed - ranked by revenue exposure. Then we hypothesis, test, and learn. Across PDP, collections, cart, checkout.
Shopify-native CRO inside your design and development system - so winning tests become permanent architecture, not abandoned experiments. Average clients see 15-25% CVR improvement within 90 days.
How would you like your inbox to be flooded with orders like this?
A working Shopify system does not send slideware. It sends orders - compounding, every day. This is what that looks like before it hits the dashboard.

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.

Objections
- Do you guarantee a conversion lift?
- No honest team does. But we guarantee a rigorous process: research-led prioritization, clear hypotheses, structured testing, and decisions tied to evidence - not opinion. Clients typically see 15-25% CVR improvement within 90 days.
- Isn't this just A/B testing?
- No. A/B testing is a tactic. CRO is a system. We diagnose money paths, prioritize by revenue impact, ship high-confidence fixes, run tests where statistical power exists, and compound wins in architecture - not in tool reports.
- How fast do results show?
- Quick wins land in weeks. Durable compounding needs a 90+ day roadmap because you're fixing the biggest leaks first, not the easiest tests.
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.
