Optimize Images for Modern Formats
High Impact+15 points estimated
Why It Matters
Images account for 1,816 KiB of wasted bytes and delay LCP by 600ms, with the hero image being the largest contentful paint element.
How to Fix
Install WebP Express or ShortPixel plugin to automatically convert images to WebP/AVIF formats. Configure responsive image sizes in WordPress functions.php to serve appropriately sized images. Replace the 2290x1707 drill-bits image with properly sized variants for different screen sizes.

AI Performance Analysis
This WordPress site has good performance with a score of 86/100, but there are still meaningful opportunities for improvement. The biggest issue is oversized images that are slowing down your page loading - you're downloading 1.8MB more image data than necessary because images are much larger than their display size and aren't using modern formats like WebP. Additionally, render-blocking JavaScript and CSS files are delaying your First Contentful Paint by about 1.3 seconds. Optimizing your images to match their display dimensions, converting them to WebP format, and deferring non-critical scripts could easily push your performance score into the 90s and improve user experience significantly.
Other Optimization Recommendations
Eliminate Render Blocking Resources
High Impact+12 points estimatedWhy It Matters:
CSS and JavaScript files are blocking initial page render and delaying FCP by 1,250ms.
How to Fix:
Use WP Rocket or Autoptimize to defer non-critical CSS and JavaScript. Move jquery.min.js to load asynchronously since it's causing the longest blocking delay (792ms). Inline critical CSS for above-the-fold content and defer logo-slider.css and woocommerce.css.
Fix Image Dimension Attributes
Medium Impact+8 points estimatedWhy It Matters:
Missing width and height attributes on carousel images can cause layout shifts affecting user experience.
How to Fix:
Add explicit width='120' height='22' attributes to partner logo images in the Slick carousel. Update your WordPress theme's image output functions to always include dimensions. Use CSS aspect-ratio property as backup for responsive behavior while maintaining layout stability.
