Optimize JavaScript Bundle Size
High Impact+25 points estimated
Why It Matters
Excessive JavaScript execution time (1.5s) and unused JavaScript (364 KiB) are blocking the main thread and delaying interactivity.
How to Fix
Split your vendor.js bundle into smaller chunks and implement code splitting. Remove unused JavaScript from vendor.lcoiit.js (80% unused). Use WordPress plugins like Asset CleanUp to defer non-critical scripts. Consider removing or replacing heavy third-party scripts from tracking services.

AI Performance Analysis
This WordPress site has poor performance with a score of 65/100, primarily due to excessive JavaScript that takes 8.6 seconds to make content visible to users. The biggest problem is JavaScript execution time of 1.5 seconds combined with 192 KiB of unused CSS, which significantly delays page rendering and makes the site feel sluggish. Additionally, the site suffers from render-blocking resources and forced reflows that could save an estimated 2+ seconds in load time. Optimizing JavaScript bundles, removing unused CSS, and deferring non-critical scripts could improve the score by 25+ points and dramatically enhance user experience.
