Cut First Contentful Paint by 45% with Targeted Script Load Optimizations

After auditing frontend performance on DentalPlans.com, I discovered that several first-party scripts were unnecessarily blocking rendering. These scripts were loaded too early, had tangled dependency chains, and weren’t leveraging modern load strategies like defer.

I refactored the load order and resolved the dependency issues to ensure essential content could render without delay.

These changes dramatically improved front-end performance:

  • First Contentful Paint dropped 45.4% (8.793s → 4.797s)
  • Largest Contentful Paint improved by 65.8% (16.092s → 5.495s)
  • Cumulative Layout Shift was nearly eliminated (0.844 → 0.142)
  • Total Blocking Time saw a modest reduction (14.43s → 13.83s)

The result was a faster, more stable page load experience—which is especially critical for SEO and conversion.
