Implement Efficient Caching Strategy

High Impact+15 points estimated

Why It Matters

Poor cache lifetimes waste 242 KiB on repeat visits, directly impacting LCP by 150ms.

How to Fix

Configure Next.js to set proper cache headers for static assets in next.config.js. Extend Facebook Pixel cache lifetime from 20 minutes to 24 hours. Use CDN edge caching for font files and configure immutable cache headers.

What This Score Means

A score of 70 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.

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 Next.js site has poor performance with a score of 70/100, primarily due to excessive JavaScript execution blocking the main thread for 3.3 seconds. The biggest issue is JavaScript bloat from third-party scripts like Google Analytics, Facebook Pixel, and TikTok tracking, which are consuming over 335KB of unused code and creating a 14.5-second delay before the page becomes fully interactive. Removing unused JavaScript, implementing better caching policies (currently missing 242KB of cacheable resources), and cleaning up 25KB of unused CSS could dramatically improve performance and reduce the painful 1+ second blocking time that makes the site feel sluggish to users.

Other Optimization Recommendations

Optimize Third-Party JavaScript Loading

High Impact+25 points estimated

Why It Matters:

Third-party scripts consume 2.2s execution time and block main thread with 1,055ms Total Blocking Time.

How to Fix:

Implement lazy loading for Facebook Pixel and Google Analytics using Next.js Script component with strategy='afterInteractive'. Move TikTok pixel to load after user interaction. Use Partytown to offload scripts to web workers.

Remove Unused Code and Modernize JavaScript

Medium Impact+10 points estimated

Why It Matters:

335 KiB of unused JavaScript and 57 KiB of legacy polyfills unnecessarily increase bundle size.

How to Fix:

Use Next.js bundle analyzer to identify dead code in Google Tag Manager and analytics scripts. Update build target in next.config.js to exclude legacy browser support. Implement dynamic imports for non-critical features using Next.js code splitting.
