Optimize Image Compression and Delivery
High Impact+10 points estimated
Why It Matters
Large banner images are delaying LCP by 1.05 seconds and consuming 178 KiB unnecessarily.
How to Fix
Increase compression on the Brooks Glycerin and Gel Nimbus banner images to reduce their size by ~100KB and 77KB respectively. Implement responsive images with proper srcset attributes. Add explicit width and height attributes to prevent layout shifts during image loading.

AI Performance Analysis
This website has moderate performance issues with a score of 73/100, but there are significant opportunities for improvement. The biggest problem is render-blocking CSS files that are delaying your page's initial display by nearly 1.5 seconds, directly impacting both First Contentful Paint (2.7s) and Largest Contentful Paint (6.0s). The site is also loading 70KB of unused CSS code and has poorly compressed images that could save an additional 178KB. Fixing these render-blocking resources and optimizing images could easily improve your performance score by 15-20 points and dramatically speed up page loading for users.
Other Optimization Recommendations
Eliminate Render-Blocking CSS Resources
High Impact+12 points estimatedWhy It Matters:
CSS files are blocking initial page render and delaying LCP by 1.45 seconds.
How to Fix:
Move non-critical CSS files like ArticleCard and Carousel components to load asynchronously using media='print' onload technique. Inline critical above-the-fold CSS directly in the HTML head. Defer the fb_lightbox.css campaign file since it's not needed for initial render.
Remove Unused CSS and JavaScript
Medium Impact+8 points estimatedWhy It Matters:
Unused code is wasting 265 KiB of bandwidth and slowing down page processing.
How to Fix:
Remove or defer the unused Google reCAPTCHA JavaScript (200KB waste) until actually needed for form submission. Strip unused CSS rules from the main stylesheet, particularly the 95% unused reCAPTCHA styles and 75% unused main CSS. Use code splitting to load components only when required.
