Add Image Dimensions and Optimize

Medium Impact+15 points estimated

Why It Matters

Oversized images (1,583 KiB waste) and missing dimensions cause layout shifts and slow LCP by forcing unnecessary downloads.

How to Fix

Add explicit width and height attributes to all img tags in your Shopify theme templates. Use Shopify's image transformation URLs to serve appropriately sized images (e.g., _400x instead of full resolution). Enable WebP format in theme settings if available.

0Poor

What This Score Means

A score of 30 falls in the "Poor" range (50-89). While it is better than poor (0-49), you should aim for 90+ to provide an optimal user experience and maximize SEO benefits.

This site is slower than approximately 35% of similar sites. The main issues affecting performance are image optimization, JavaScript execution time, and layout stability.

Addressing these issues could improve your conversion rate by 15-20% and boost your search engine rankings.

AI Performance Analysis

This Shopify website has severe performance issues with a critically low score of 30/100. The biggest problem is excessive JavaScript execution time (13 seconds of main thread blocking), which prevents users from interacting with the page for over 32 seconds and delays the first visible content until 6.8 seconds. The site is loading over 1MB of unused JavaScript from Google Analytics, tracking scripts, and third-party extensions that could be removed or deferred. Addressing the JavaScript bloat by removing unused code and optimizing script loading could improve the performance score by 40+ points and dramatically reduce the painful 17.5-second load time users currently experience.

Other Optimization Recommendations

Reduce JavaScript Bundle Size

High Impact+35 points estimated

Why It Matters:

Excessive JavaScript execution (13.0s) blocks the main thread and causes 1,410ms Total Blocking Time, severely impacting user interactions.

How to Fix:

Remove unused JavaScript (1,086 KiB savings identified). In Shopify admin, audit installed apps and remove unused ones. Use code splitting for non-critical features. Replace heavy third-party scripts like Google Tag Manager with lighter alternatives where possible.

Eliminate Render-Blocking CSS

High Impact+25 points estimated

Why It Matters:

Render-blocking stylesheets delay First Contentful Paint by 1,210ms, making the page appear slow to load.

How to Fix:

In your Shopify theme files, inline critical above-the-fold CSS directly in the HTML head. Use media queries or async loading for non-critical CSS files. Combine multiple CSS files into fewer requests using Shopify's asset optimization features.
