WHO THIS IS FOR
The Right Fit for This Service.
You're running paid traffic to a Shopify store and conversion rates aren't where they should be - and you've run out of obvious things to fix.
Your store is slow. Google PageSpeed shows red. You've installed too many apps and nobody has cleaned up the technical debt.
You've never run a proper audit and suspect there are performance gaps actively costing revenue - but you need someone to find them and prioritize them.
You're about to scale ad spend and want to make sure the store can absorb the traffic without conversion dropping.
HOW WE WORK
No Optimization Without Data.
No Recommendations Without Evidence.
-
01
Audit
Full technical and UX audit - performance benchmarks, heatmaps, session recordings, and funnel analysis. We find what's broken and quantify it.
-
02
Prioritization
Issues ranked by revenue impact, not technical complexity. You get a prioritized fix list with estimated impact, not a 40-point to-do.
-
03
Implementation
Changes made in staging, tested, then deployed. A/B tests configured where variance is high enough to test before committing.
-
04
Measurement & Report
Post-implementation measurement against your baseline. We report the actual change - not directional guesses.

Questions About Shopify Optimization & CRO.
1. What does a Shopify CRO agency actually do?
A Shopify CRO agency audits your store's data - heatmaps, session recordings, funnel analytics - identifies where visitors drop off, and implements changes designed to increase the percentage of visitors who complete a purchase. BrainBox combines technical optimization (speed, accessibility, code debt) with UX-driven conversion improvements rather than treating them as separate workstreams.
2. What are Core Web Vitals, and why do they matter for a Shopify store?
Core Web Vitals are Google's performance metrics: LCP (Largest Contentful Paint), INP (Interaction to Next Paint), and CLS (Cumulative Layout Shift). Failing these thresholds directly impacts your search ranking and your user experience. Shopify stores with too many apps and unoptimized themes routinely fail them.
3. How much can speed optimization improve a Shopify store's conversion rate?
Google's own data shows that a 1-second improvement in mobile load time improves conversion rates by up to 27%. For a store processing $50k/month, that's a meaningful revenue difference. We measure the actual impact against your baseline rather than citing industry averages.
4. What's the difference between a speed audit and a full CRO audit?
A speed audit focuses specifically on technical performance - load time, Core Web Vitals, asset optimization. A full CRO audit includes speed but also covers UX friction points, form completion rates, cart abandonment behavior, and page hierarchy. We offer both as standalone engagements or combined.
5. Do you run A/B tests as part of the optimization work?
Yes, where the traffic volume justifies it. A/B testing requires enough sessions to reach statistical significance - for lower-traffic stores, we prioritize direct implementation of high-confidence changes over running tests that won't reach a reliable result.
6. How do you measure the impact of your optimization work?
We establish a baseline before any changes go live - conversion rate, session duration, bounce rate, revenue per session. Post-implementation, we measure against that baseline over 30 to 60 days. You get a report showing actual movement, not a summary of tasks completed.
