Remove Unused JavaScript Code

High Impact+25 points estimated

Why It Matters

Unused JavaScript wastes 254 KiB and delays LCP by 1.35 seconds, severely impacting page performance.

How to Fix

In Shopify Admin, go to Online Store > Themes > Actions > Edit Code. Remove or defer the Lookfy extension (52KB waste), optimize Google Tag Manager by removing unused tags, and audit Ryviu app for necessary features only. Use Shopify's Script Tag API to load non-critical scripts after page load.

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

AI Performance Analysis

This Shopify site has severe performance issues with a critically low score of 21/100. The biggest problem is massive JavaScript bloat - the site loads 254 KiB of unused JavaScript that delays page rendering by over 1.3 seconds, combined with render-blocking scripts that add another 570ms delay. The site also suffers from a devastating redirect issue (adding 780ms) and takes an extremely slow 18 seconds for the largest content to appear, creating a terrible user experience. Fixing the redirect, removing unused JavaScript from third-party apps like Lookfy and cookie consent tools, and optimizing the oversized images could potentially improve the performance score by 40+ points and drastically reduce load times.

Other Optimization Recommendations

Fix Render Blocking Resources

High Impact+18 points estimated

Why It Matters:

Critical CSS and JavaScript block initial page render for 570ms, preventing users from seeing content quickly.

How to Fix:

Move Cookie Consent script to load asynchronously using async attribute. Inline critical CSS for above-the-fold content in your theme.liquid file. Defer Lookfy extension CSS by adding media='print' onload='this.media="all"' to the link tag, then loading it after page renders.

Optimize LCP Image Loading

High Impact+22 points estimated

Why It Matters:

The hero image uses lazy loading and lacks priority hints, causing an 18-second LCP that fails Core Web Vitals.

How to Fix:

Edit your theme's slideshow section template to remove loading='lazy' from the first hero image. Add fetchpriority='high' attribute to the LCP image element. Preload the hero image in theme.liquid using <link rel='preload' as='image' href='hero-image-url'> in the <head> section.
