Magento Performance Audit Checklist

Introduction

Magento is a powerful ecommerce platform, but without regular performance audits, even the best Magento stores can become slow, unstable, and conversion-unfriendly. Page speed, server configuration, third-party extensions, and database health all directly impact user experience and revenue.

This Magento Performance Audit Checklist is designed for store owners, CTOs, and ecommerce teams who want to ensure their Magento store is fast, scalable, and ready for growth in 2026 and beyond.

“A slow Magento store doesn’t just lose speed — it loses customers, rankings, and revenue.”

Why Magento Performance Audits Matter

A performance audit helps you:

Identify speed bottlenecks before they impact sales
Improve Core Web Vitals and SEO rankings
Reduce server costs through optimization
Prepare your store for traffic spikes and scaling
Improve checkout completion rates

Regular audits are essential for enterprise Magento stores, large catalogs, and high-traffic websites.
