Fix Font Display Blocking Issue

Medium Impact+8 points estimated

Why It Matters

Custom font loading blocks text rendering for 400ms, delaying First Contentful Paint.

How to Fix

Add font-display: swap to your @font-face declaration for the saudi_riyal font. Preload the critical font file in the document head. Consider using font metric overrides to reduce layout shift when the font loads.

What This Score Means

A score of 63 falls in the "Needs Improvement" 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.

AI Performance Analysis

This website has poor performance with a score of 63/100, primarily due to excessive JavaScript blocking the main thread for 2 seconds and causing a very slow Largest Contentful Paint of 12.9 seconds. The biggest opportunity for improvement is reducing unused JavaScript, which could save 518 KiB and improve loading by over 3 seconds, followed by optimizing the main image that takes over 7 seconds to load due to resource delays. Additional quick wins include removing 16 KiB of unused CSS, implementing proper font display settings to save 400ms, and updating the JavaScript build process to avoid unnecessary polyfills that add 13 KiB of legacy code. These optimizations could dramatically improve user experience and push the performance score well into the good range.

Other Optimization Recommendations

Reduce Unused JavaScript Bundle Size

High Impact+25 points estimated

Why It Matters:

Unused JavaScript accounts for 518 KiB and delays LCP by 3.1 seconds while blocking main thread work.

How to Fix:

Implement code splitting in your Next.js build to break large chunks into smaller, route-specific bundles. Remove or defer the Google Tag Manager script (65KB unused). Use Next.js dynamic imports for non-critical components to reduce initial bundle size.

Optimize LCP Image Loading Strategy

High Impact+20 points estimated

Why It Matters:

The hero image has a 7.3-second delay (2.3s load delay + 5s duration) causing the 12.9s LCP score.

How to Fix:

Preload the hero image using <link rel='preload' as='image'> in the document head. Optimize the image compression to reduce the 170KB file size. Consider using a smaller, optimized version specifically for above-the-fold display.
