Remove Unused JavaScript Code
High Impact+12 points estimated
Why It Matters
199 KiB of unused JavaScript causes 900ms delay in LCP, primarily from Google Ads scripts.
How to Fix
Use WP Asset CleanUp to disable Google Ads on pages that don't need them. Implement lazy loading for ad scripts using WP Rocket's delay JavaScript feature. Consider switching to lighter ad management solutions or load ads only when user scrolls near ad placement.

AI Performance Analysis
This WordPress site has good performance with a score of 89/100, but there are still opportunities for improvement. The biggest issue is render-blocking CSS files that are delaying the initial page render by an estimated 660ms, which affects how quickly users see content. Additionally, the site is loading nearly 200KB of unused JavaScript from Google AdSense and other scripts, which could save 900ms in loading time if optimized. Quick wins include deferring non-critical CSS, removing unused JavaScript, and converting the hero image to WebP format for better compression.
Other Optimization Recommendations
Eliminate Render-Blocking CSS Resources
High Impact+8 points estimatedWhy It Matters:
CSS files are blocking initial render for 660ms, delaying First Contentful Paint and LCP.
How to Fix:
Install Autoptimize or WP Rocket to inline critical CSS. Move LearnDash CSS files (quiz, lesson video) to load conditionally only on relevant pages. Use media queries to defer non-critical stylesheets like print styles.
Optimize Hero Image Format
Medium Impact+3 points estimatedWhy It Matters:
The main hero image wastes 9.7 KiB and impacts LCP as it's the largest contentful element.
How to Fix:
Convert the iMariners-Hero-Image.jpg to WebP format using ShortPixel or EWWW Image Optimizer plugins. Ensure the srcset includes WebP versions with JPEG fallbacks. Add fetchpriority='high' to the hero image (already present but verify implementation).
