Why It Matters

Analytics and tracking scripts execute for 1.5 seconds, blocking user interactions and increasing Total Blocking Time.

AI Performance Analysis

This Next.js site has good performance with a score of 88/100, but has significant JavaScript execution issues that are hurting user interactivity. The biggest problem is excessive JavaScript processing time (1.5 seconds), particularly from analytics scripts like Yandex Metrica and Google Tag Manager, which is causing a poor Time to Interactive score of 11.4 seconds and high Total Blocking Time of 380ms. The site is also loading 311 KiB of unused JavaScript and using outdated JavaScript polyfills that add unnecessary 36 KiB of legacy code for modern browsers. Removing unused JavaScript, optimizing third-party scripts, and updating the build process to avoid legacy polyfills could dramatically improve interactivity and reduce blocking time by several hundred milliseconds.

How to Fix:

Resize licensect.jpg from 2480x3307 to match display size (315x431) and compress to WebP format. Update Next.js Image components to use responsive sizes prop with proper breakpoints. Enable next/image optimization for all static images in your public folder.

Eliminate Render-Blocking CSS

High Impact+7 points estimated

Why It Matters:

CSS files block initial page render for 410ms, delaying First Contentful Paint by 400ms.

How to Fix:

Extract critical CSS for above-the-fold content and inline it in the document head. Use Next.js dynamic imports for non-critical CSS components. Implement font-display: swap for custom fonts and preload the primary font file.
