Optimize Image Delivery
High Impact+15 points estimated
Why It Matters
Oversized images waste 244KB of bandwidth and delay LCP by 350ms, particularly the hero banner image.
How to Fix
Implement responsive images using srcset for different screen sizes. Add fetchpriority='high' to the hero banner image as suggested by PageSpeed. Resize images to match their display dimensions - the hero image loads at 1600x900 but displays at 412x232.

AI Performance Analysis
This website has below-average performance with a score of 74/100, primarily held back by slow loading times. The biggest problem is a redirect from the non-www version that adds an unnecessary 780ms delay, combined with render-blocking CSS and fonts that prevent content from appearing for 3.7 seconds. The site also suffers from oversized images that are much larger than needed for their display size, wasting 244KB of bandwidth and further slowing the Largest Contentful Paint to 4.8 seconds. Fixing the redirect, optimizing image sizes, and deferring non-critical CSS could improve the performance score by 15-20 points and significantly enhance user experience, especially on mobile devices.
Other Optimization Recommendations
Fix Page Redirect Chain
High Impact+25 points estimatedWhy It Matters:
The redirect from joalexander.co.uk to www.joalexander.co.uk delays LCP by 800ms and FCP by 800ms.
How to Fix:
Configure your server to directly serve the canonical www version. Update all internal links to use https://www.joalexander.co.uk/. Set up a 301 redirect at DNS level rather than server level to eliminate the network roundtrip.
Eliminate Render-Blocking CSS
High Impact+20 points estimatedWhy It Matters:
Render-blocking CSS delays First Contentful Paint by 1.8 seconds, preventing users from seeing any content.
How to Fix:
Inline critical CSS for above-the-fold content directly in the HTML head. Load non-critical CSS asynchronously using media='print' onload technique. Split the large merged CSS file (81KB) into critical and non-critical portions using tools like Critical or PurgeCSS.
