Medium Impact+4 points estimated
Why It Matters
Missing width and height attributes on images cause layout shifts and hurt user experience during page load.
How to Fix
Add explicit width='66' height='36' attributes to all Clutch logo images in your WordPress theme. Update your theme's image output functions to always include dimensions. Use WordPress's wp_get_attachment_image() function which automatically includes size attributes.

AI Performance Analysis
This WordPress site has poor performance with a score of 69/100. The biggest problem is excessive unused JavaScript (290 KiB), primarily from Google Tag Manager scripts, which is causing a very slow Largest Contentful Paint of 5.5 seconds and Time to Interactive of 11 seconds. The site is also suffering from forced reflows caused by JavaScript querying layout properties, which blocks the main thread for over 2 seconds. To improve performance, focus on removing or deferring unused JavaScript, optimizing the main-thread work, and adding explicit width/height attributes to images to prevent layout shifts.
Other Optimization Recommendations
Remove Unused JavaScript Code
High Impact+12 points estimatedWhy It Matters:
290 KiB of unused JavaScript from Google Tag Manager delays LCP by 300ms and blocks user interactions.
How to Fix:
Audit your Google Tag Manager containers (GTM-W9RRXH8) to remove unnecessary triggers and tags. Use GTM's built-in tag templates instead of custom HTML. Consider loading GTM asynchronously or moving non-critical tracking to load after page interaction using WordPress hooks.
Optimize Cache Strategy
High Impact+8 points estimatedWhy It Matters:
Poor cache lifetimes for critical resources cost 450ms on LCP and force unnecessary re-downloads on repeat visits.
How to Fix:
Install WP Rocket or W3 Total Cache to extend cache headers for static assets to 1 year. Configure your server to set longer cache times for Cookiebot scripts (currently only 17 minutes). Set up proper ETags and Last-Modified headers for better browser caching.
