This story gives practical fixes you can apply now to handle peak traffic and convert more visitors.

Images are the largest files in most stores. Compress and serve next-gen formats (WebP/AVIF), resize to display size, lazy-load below the fold, and use responsive srcset.
These changes cut load time and keep visual quality high for shoppers.

Ads, chat widgets, and analytics slow pages. Audit scripts, remove unused apps, and load nonessential scripts after page paint.
Defer or async where possible, this reduces main-thread blocking and speeds up first contentful paint.

Each installed app can inject CSS/JS. Uninstall unused apps, disable unused features, and consolidate functions into fewer apps.
Replace heavy apps with lightweight alternatives to cut requests and CPU time on mobile devices.

Deliver assets via a CDN to cut latency. Enable aggressive caching for static files and use asset hashing/versioning to avoid cache stalls.
Proper caching reduces server hits during BFCM traffic spikes.
