PrestaShop Speed & Core Web Vitals Audit

The PrestaShop Speed & Core Web Vitals Audit

The PrestaShop Speed & Core Web Vitals Audit measures real PrestaShop stores using Lighthouse and field data, providing a prioritized plan with actionable fixes.

• Who it is for: Stores with slow pages, poor Core Web Vitals, high time-to-first-byte, or rising mobile bounce; and agencies needing a measured second opinion before blaming the host or rebuilding the theme.
• What the report looks like: Findings are ranked before being described, showing the first thing to do. The example document includes your store's name, URLs, and modules.
• What the profile usually turns up: Real bottlenecks such as un-indexed queries, misconfigured caches, oversized images, and blocking scripts.
• What is, and is not, included: The audit provides the diagnosis and plan but does not implement changes. Fixes like caching tuning or hosting migration are scoped separately.

Why trust this diagnosis

We have found and fixed performance issues on our own PrestaShop stores, including render hotspots and critical CSS regressions. Our tooling is used by merchants relying on performance optimization.

Where it fits

Pair this audit with a Hosting Audit and Theme Suitability Review, focusing on the two layers most often dominating performance: the host and the theme.

How every finding is written

Symptoms, evidence, causes, fixes, effort, and confirmation steps are detailed for developers to act on without further questions. The tool supports PrestaShop 1.6 through 9, PHP 7.1 and newer versions.
