// WHY IT MATTERS
A slow site isn't a technical problem. It's a revenue problem.
Every second a Shopify or WordPress page takes to load is a visitor deciding whether to stay or leave. Google ranks fast sites higher. Customers convert on fast sites more. We treat Core Web Vitals and conversion rate as the same job — because to a customer, they are.

// THE PERSON BEHIND PACELO
Hi, I'm Arsalan — founder of Pacelo.
I'm a Shopify and WordPress developer with a single obsession: making ecommerce stores load faster and sell more. I've rebuilt stores for founders across the US, UK, and Canada — cutting LCP by 60%, tripling conversion rates, and fixing Core Web Vitals that were quietly costing sales every day. Every project I take on, I treat like my own store is on the line.

// CASE STUDY — RADEANT.COM
A haircare brand's Shopify store, rebuilt for speed and sales
| Metric | Before | After | Change |
|---|---|---|---|
| Largest Contentful Paint (LCP) | 5.0s | 2.0s | ▼ 60% |
| Conversion rate | 1.0× | 3.1× | ▲ 210% |
| Core Web Vitals | Needs work | Pass | ✓ |
We rebuilt the Radeant Shopify theme from the ground up: a custom multi-step bundle builder with discount logic, a lightweight hero slider with proper mobile image handling, and a product grid engineered for fast first paint — then kept tuning post-launch until the Core Web Vitals held and the conversion lift was sustained.

// HOW WE WORK
From audit to measurable lift, in four stages
STAGE 01
Audit
A full Core Web Vitals and conversion audit of your Shopify or WordPress store — no fluff, just what's actually slowing you down and costing you sales.
STAGE 02
Plan
A prioritized roadmap: what to fix first, what it costs, and what kind of conversion or LCP lift to expect — before any code gets written.
STAGE 03
Build
Shopify Liquid or WordPress, shipped in reviewable stages — never waiting on a single big reveal, always testable incrementally.
STAGE 04
Measure
Real PageSpeed Insights scores and real conversion data post-launch — we keep tuning until the Core Web Vitals hold and the lift sticks.
// OUR COMMITMENT TO YOU
We only win when you win.
Most agencies bill by the hour regardless of outcome. We don't. Every Pacelo engagement is milestone-based — you review real deliverables before the next payment releases. And if we don't hit the agreed PageSpeed or conversion targets, we keep working until we do. No excuses.
Money-Back Guarantee
If we don't deliver measurable improvement — faster LCP, higher PageSpeed score, improved Core Web Vitals — you don't pay the final milestone. Simple.
Pay on Results
Milestone-based payment structure. You approve each stage before releasing funds. No upfront lump sums, no invoices for work you haven't seen yet.
Free Audit, Zero Obligation

Common questions about Pacelo
What does Pacelo do?
Pacelo is a performance-first Shopify and WordPress agency. We build, migrate, and speed-optimize ecommerce stores for founders in the US, UK, and Canada — specializing in Core Web Vitals, LCP optimization, and conversion rate improvements.
How much can you improve my store's speed?
Our Radeant case study achieved a 60% LCP reduction (5.0s → 2.0s) and a 3.1× conversion rate lift. Most Shopify stores we work on see significant PageSpeed score and Core Web Vitals improvements after a rebuild or optimization pass.
Do you work with Shopify or WordPress?
Both. We handle custom Shopify Liquid themes, migrations, bundle builders, and checkout flows — plus WordPress builds with Elementor, plugin development, and full performance optimization. All built for speed from day one.
What is Core Web Vitals optimization?
Core Web Vitals are Google's user experience metrics: LCP (loading speed), CLS (visual stability), and INP (responsiveness). Optimizing them improves Google rankings and directly increases ecommerce conversion rates.
