What's Working

Performance strengths to maintain

⚡

Image Optimization

98.0% of images use lazy loading. excellent deferral strategy.

⚡

App Overhead

Only 1 third-party app script detected. minimal app bloat.

⚡

Meta & Technical

All key technical tags present: viewport, charset, canonical, and preconnect.

Core Web Vitals. Detailed Analysis

LCP. Largest Contentful Paint

Time until the biggest visible content element finishes loading

High Risk

~ Estimated

POOR

Good: ≤ 2.5s

Needs work: 2.5–4s

Poor: > 4s

LCP Element Detected

📷

Hero Image

Tag: <img>

class: "resource-card__image"

What's Good

Preload hint found. hero image loads early

fetchpriority='high' found. browser prioritises LCP image

Preconnect hints present. CDN connections open early

What's Slowing It Down

Hero image may not be WebP/AVIF. old formats are 30–50% heavier

Hero/first image has loading='lazy'. this actively delays the LCP element

27 render-blocking script(s) pause the browser before it can paint

35 CSS files to download before render. merge or defer non-critical sheets

Large HTML (2830.2 KB) increases server response time (TTFB)

Why It Matters

LCP is what users feel as 'the page loaded'. Every 100ms slower means up to 1% fewer conversions. Google uses LCP as a ranking signal. stores with LCP above 4s rank lower and have 70% higher bounce rates on mobile.

Shopify-Specific Fixes

1In theme.liquid: add <link rel="preload"> for hero image. cuts LCP by 0.5–1s.

2Add fetchpriority='high' to your hero <img> tag. tells browser to load this first.

3In Liquid templates use: {{ image | image_url: width: 1200, format: 'webp' }}. Shopify serves WebP via CDN.

4Remove loading='lazy' from the first visible image in your hero section.

5In theme.liquid: move all non-critical scripts below </body> or add defer attribute.
