Reduce JavaScript Blocking Time

High Impact+6 points estimated

Why It Matters

Total Blocking Time of 310ms and Max Potential FID of 240ms prevent user interactions and hurt INP scores.

How to Fix

Use LiteSpeed Cache's JS optimization to defer non-critical scripts. Break up long-running JavaScript tasks into smaller chunks using setTimeout or requestIdleCallback. Audit WordPress plugins for heavy scripts and consider alternatives or lazy loading.

What This Score Means

A score of 92 falls in the "Good" 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 WordPress site performs well overall with a score of 92/100, but has room for improvement in user interactivity. The biggest problem is excessive unused CSS - a bloated stylesheet that's 96% unnecessary is blocking page rendering and wasting 58 KB of bandwidth. This CSS file is delaying both your First Contentful Paint and Largest Contentful Paint, while also contributing to a 240ms potential delay when users try to interact with your page. Cleaning up this unused CSS and optimizing your stylesheets could eliminate render-blocking issues and make your contact page feel more responsive to visitors.

Other Optimization Recommendations

Eliminate Render Blocking CSS

High Impact+8 points estimated

Why It Matters:

The main CSS file is blocking initial render and delaying LCP by 100ms with 96% unused styles.

How to Fix:

Configure LiteSpeed Cache to enable Critical CSS generation for above-the-fold content. Defer the large CSS file (b157279af916a58e03b7ff92faa68e6b.css) using async loading. Remove or inline only essential CSS needed for initial render in WordPress theme functions.php.

Fix Forced Reflow Issues

Medium Impact+4 points estimated

Why It Matters:

JavaScript is causing 194ms of forced reflows by reading layout properties after DOM changes, degrading INP performance.

How to Fix:

Audit theme and plugin JavaScript for DOM property reads like offsetWidth after style changes. Batch DOM reads before writes in your theme's JavaScript files. Use CSS transforms instead of changing layout properties for animations in WordPress themes.
