AI Performance Analysis

This WordPress site has poor performance with a score of 51/100, indicating significant issues that hurt user experience. The biggest problem is excessive unused JavaScript, particularly from Google reCAPTCHA, which is wasting over 500KB and delaying page loading by 5+ seconds. The site also suffers from 15 layout shifts that cause content to jump around as it loads, and images are poorly optimized, wasting an additional 422KB of data. Cleaning up unused JavaScript, optimizing images with modern formats like WebP, and fixing layout stability issues could improve the performance score by 30+ points and dramatically reduce the 12+ second loading times.

Other Optimization Recommendations

Fix Layout Shift Issues

High Impact+15 points estimated

Why It Matters:

15 layout shifts with a CLS score of 0.128 are causing content to jump during page load, harming user experience.

How to Fix:

Add explicit width and height attributes to your H1 headings that are causing shifts. Reserve space for dynamic content with CSS min-height properties. Preload your Montserrat font using <link rel='preload'> to prevent font swap layout shifts.

Optimize Image Delivery Format

Medium Impact+10 points estimated

Why It Matters:

422 KiB of image waste is slowing LCP by 300ms due to oversized images and outdated formats.

How to Fix:

Install Imagify or ShortPixel to automatically convert images to WebP format. Enable responsive images in your WordPress theme. Resize the 500x728 screenshot to match its displayed size of 159x231 pixels using WordPress's built-in image editor.
