Optimize Image Delivery Performance
Medium Impact+12 points estimated
Why It Matters
Images are oversized by 637 KiB and the main banner image delays LCP with unnecessary file size.
How to Fix
Install Smush or ShortPixel to automatically compress and resize images to actual display dimensions. Replace PNG badges with WebP format for 30% smaller files. Set proper width/height attributes on award badge images to prevent layout shifts.

AI Performance Analysis
This website has poor performance with a score of 50/100, indicating significant issues that are hurting user experience. The biggest problem is excessive JavaScript execution time (2.7 seconds), which is blocking the page and creating a painfully slow Time to Interactive of nearly 20 seconds. The site is loading too much unused JavaScript (765 KiB of waste) from tracking scripts like Facebook Pixel and TikTok analytics, plus render-blocking CSS files that delay the initial paint. Reducing unnecessary JavaScript, deferring non-critical scripts, and optimizing the large 293 KiB banner image could dramatically improve performance and reduce the 900ms of blocking time that's frustrating users.
Other Optimization Recommendations
Remove Unused JavaScript Code
High Impact+25 points estimatedWhy It Matters:
765 KiB of unused JavaScript is blocking rendering and causing 900ms of Total Blocking Time.
How to Fix:
Remove or defer third-party tracking scripts (ContentSquare, TikTok Analytics, Facebook Pixel) that are 60-80% unused. Use WordPress plugins like Asset CleanUp to conditionally load scripts only where needed. Consider lazy loading analytics until user interaction occurs.
Eliminate Render Blocking Resources
High Impact+20 points estimatedWhy It Matters:
CSS files are delaying First Contentful Paint by 650ms and blocking initial page render.
How to Fix:
Use WordPress optimization plugins like WP Rocket or Autoptimize to inline critical CSS for above-the-fold content. Defer loading of Bootstrap CSS (31 KiB) and other non-critical stylesheets. Preload the most important CSS files using <link rel='preload'>.
