CRO & UX Optimization

Turn the traffic you already have into more orders. We find where your store leaks revenue, then test and fix — methodically, with the numbers to prove it.

Shopify conversion rate optimization, done with evidence

Most Shopify stores don't have a traffic problem. They have a leak somewhere between the product page and the order confirmation. Saints & Sparrows finds where your store loses buyers, fixes what's clearly broken, and tests what isn't obvious. Every change is tied to conversion rate, average order value and revenue, so you know what each one was worth.

Where Shopify stores usually leak

The same problems show up again and again. Product pages that bury the answer to "will this work for me?", variant pickers that confuse more than they help, and shipping costs revealed too late. Mobile layouts that shift as apps load, so shoppers tap the wrong thing. Collection pages without useful filters. A cart that asks for a decision the shopper wasn't ready to make. None of these need a redesign. Most need a clear diagnosis and a targeted fix.

How a CRO audit works

We start by walking your funnel on real phones and desktops, the way a first-time buyer would. Then we pull the analytics to see where sessions drop off, by device, traffic source and template. Each opportunity is scored on likely impact, our confidence in it, and the effort to ship it. You get a prioritized roadmap, not a 60-slide deck of ideas nobody will build.

A/B testing: when it helps and when it doesn't

Testing only works when there's enough traffic to reach a trustworthy result in a reasonable window. When there is, we run disciplined A/B and multivariate tests on layout, copy, offers and page structure, and we don't call winners early. When volume is too thin for clean tests, we say so and focus on well-established fixes and qualitative research instead. An underpowered test that "wins" is worse than no test at all.

Speed, checkout and mobile UX

Slow and unstable pages lose sales. We treat Core Web Vitals as a conversion problem, not just an SEO score. We work on app script bloat, image handling and layout shift, which our Shopify site speed guide covers in detail. For Shopify Plus stores, checkout extensibility opens up upsells, custom fields and validation. Whether that's worth the upgrade is a math question our Shopify vs Shopify Plus guide answers.

We ship the changes

Recommendations are cheap. We build the winning changes into your theme, verify them on real devices, and measure the result. CRO works best alongside storefront development and clean analytics, and each cycle builds on the last.

How it works

  1. 1Audit — we walk your funnel on real devices and pull the analytics to find the leaks.
  2. 2Prioritize — every opportunity scored by impact, confidence, and effort.
  3. 3Test — disciplined experiments with enough traffic to trust the result.
  4. 4Ship — winning changes go live; we're honest about what's conclusive.
  5. 5Compound — each cycle builds on the last toward a measurable revenue goal.
Small changes on the money pages — a clearer PDP, a checkout that doesn't leak — are usually where the revenue hides.

Common questions

How much traffic do we need to test?
Enough to reach significance in a reasonable window. If volume is thin, we focus on best-practice fixes and qualitative research instead of underpowered tests.
Do you just recommend, or make the changes?
We ship. You get fixes live in your store, not a slide deck of ideas.
What do you measure?
Conversion rate, add-to-cart, checkout completion, and AOV — tied to revenue, not vanity metrics.
How fast do we see results?
Some fixes lift immediately; some tests need weeks to conclude. We're straight about which is which.
