Ecommerce CRO checklist for brands past the template stage
Conversion rate optimization is not button color. It’s a disciplined loop across PDP, collection, cart, and trust - measured against revenue, not vanity metrics that look good in a deck.

If the store looks finished but conversion is flat, you don’t need another full redesign first. You need a CRO program that diagnoses friction with qualitative and quantitative evidence - then ships the fixes that touch money. Propeller runs ecommerce CRO inside the commerce system: experience, paid landing quality, and lifecycle in the same backlog.
Start where the money moves
Prioritize money paths in this order: product discovery and search, PDP clarity (offer, imagery, social proof, shipping), cart friction, checkout trust and express pay, then mobile performance and Core Web Vitals. Fix the leaks that touch the most sessions and highest AOV before you argue about hero video. A 0.5-point lift on a bestseller beats a dramatic experiment on a long-tail SKU.

Evidence over opinion
Pair UX hypotheses with analytics and session evidence. Score every finding with impact × confidence × ease. Ship obvious technical killers (sticky mobile ATC, guest checkout / Shop Pay, broken trust copy) without waiting for a six-week test. A/B test the rest when you have enough traffic for clean reads - roughly when weekly conversions support significance, not when someone is impatient in Slack.
Connect CRO to acquisition and retention
Paid traffic into a weak PDP wastes media. Klaviyo flows into a confusing cart create the same leak twice. Treat Meta and Google landing quality as CRO surface area. Treat post-purchase and subscription UX as retention CRO. That is how a Santa Monica ecommerce CRO agency compounds - not by shipping isolated button tests forever.
Questions
How fast should CRO show results?
Quick wins can land in weeks; meaningful compounding usually takes a sustained backlog and clean measurement. Expect a roadmap, not a single magic test.
What should an ecommerce CRO audit cover?
Homepage and collection discovery, PDP clarity, cart and checkout, mobile performance, trust and offer structure, analytics integrity, and how paid and lifecycle traffic enter the funnel.
