How to Optimize Shopware 6 for Core Web Vitals (Google PageSpeed)

Google’s Core Web Vitals have become a crucial ranking factor, directly impacting both SEO performance and user experience. If your Shopware 6 store isn’t optimized for speed, you risk losing visibility, conversions, and customers.

In this guide, we’ll walk you through the key steps to improve PageSpeed Insights scores and achieve better Core Web Vitals results for your Shopware store.

What Are Core Web Vitals?

Core Web Vitals are three performance metrics Google uses to measure real-world user experience:

Largest Contentful Paint (LCP) – how quickly the main content loads. Target: under 2.5 seconds.
First Input Delay (FID) – how soon the page responds to user interaction. Target: under 100ms.
Cumulative Layout Shift (CLS) – how stable the layout is as it loads. Target: under 0.1.

Shopware 6’s flexible architecture is powerful, but without optimization, it can struggle to meet these benchmarks.

Why Core Web Vitals Matter for Shopware 6

SEO Rankings – Faster, optimized stores rank higher in Google.
Conversions – Even a 1-second delay can reduce conversion rates by up to 20%.
User Retention – Customers are less likely to bounce if the site loads smoothly.

Step-by-Step Optimization for Shopware 6

1. Optimize Hosting & Server Performance

Choose high-performance hosting with SSD/NVMe drives and PHP 8+.

2. Use Shopware 6 Caching & Performance Features

3. Image Optimization
