Optimize Hero Image Delivery

Medium Impact+5 points estimated

Why It Matters

The main hero image lacks modern format optimization, missing 10 KiB savings that could improve perceived performance.

How to Fix

Install WebP Express or ShortPixel to automatically convert the hero image to WebP format. Ensure proper srcset implementation for responsive delivery. Add preload tag for the hero image since it has fetchpriority='high'.

AI Performance Analysis

This WordPress site has good performance with a score of 83/100, but there are several optimization opportunities that could push it to excellent. The biggest issue is render-blocking CSS resources that are delaying the page's initial paint by 560ms, preventing users from seeing content quickly. The site is also suffering from forced reflows caused by ad scripts and unused code - there's 199KB of unused JavaScript and 14KB of unused CSS that could be removed to speed things up. Additionally, optimizing images to modern formats like WebP and improving font loading could provide further performance gains and create a smoother user experience.
