How an AI-powered Image Optimisation Digital Worker improved site speed and SEO for a leading UK retailer.

The Customer

• Name: Sarah (Head of E‑commerce, national retail brand) 
• Team Size: 8‑person digital and marketing team 
• Sector: Fashion & Lifestyle 

Challenge: A homepage that looked stunning — but loaded painfully slowly due to 9MB of unoptimised images.

The Problem

Sarah’s analytics revealed:

• Homepage load time: 6.2 seconds on desktop, 9+ seconds on mobile 
• High bounce rate (especially from mobile visitors) 
• Poor Google PageSpeed Insights score, hurting SEO 
• Manual image optimisation was inconsistent and time‑consuming 

Slow performance was costing sales and damaging the brand’s online reputation, especially during high‑traffic campaigns.

The Turning Point

Sarah’s team deployed our Image Optimisation Digital Worker, built with the Trusted AI Agent Builder.
It could:

• Automatically detect and optimise images in the CMS 
• Convert to next‑gen formats (WebP/AVIF) while maintaining visual quality 
• Compress at optimal ratios for speed without noticeable loss 
• Push changes directly to the live site or CDN with rollback options 
• Run scheduled audits to prevent performance regression.

Before vs After Workflow

Before

1. Designer exports image manually 
2. Uploads to online compressor tool 
3. Re‑uploads to CMS 
4. Tests manually in browser
   (10–15 mins per image, inconsistent quality) 

After

1. Sarah typed:
   
   
   “Optimise all homepage images to load in under 2MB total, maintain quality for retina screens, and update live site.”
    
2. The Image Optimisation Digital Worker: 
   • Pulled all homepage images from CMS 
   • Batch‑converted to WebP and AVIF formats 
   • Compressed with human‑eye‑optimised settings 
   • Validated visual quality using AI image comparison 
   • Pushed optimised assets live and purged CDN cache 
   • Logged changes and created instant rollback option

.

The Results

• Total homepage image size reduced from 9MB → 3MB 
• Page load time cut from 6.2s → 1.9s on desktop and 9s → 3.4s on mobile 
• Google PageSpeed Insights score improved by +28 points 
• Bounce rate reduced by 22%, boosting conversions 

Freed up 10+ hours/month previously spent on manual optimisation

Customer Quote

“The visual quality stayed perfect, but the speed difference was night and day. It’s like our website had a turbo button we didn’t know about.”

Why This Works

• Specialised Role: Purpose‑built for e‑commerce image workflows 
• No Guesswork: Balances compression with quality automatically 
• API‑to‑App Adaptability: Works with any CMS or CDN 

Preventative Maintenance: Scheduled audits stop the site from slowing down again
