Image Optimization Use an adaptive image CDN approach with Cloudflare. It resizes and optimizes images based on visitor devices and screen sizes. Leverage image format conversion to serve images in modern formats like WebP. It further reduces loading times.
A/B Testing with Cloudflare Workers Use Cloudflare Workers to run serverless functions at the network edge for A/B testing. Serve different content or design variations to different sets of visitors. Measure their impact on conversions. Experiment with product recommendations, checkout processes, or visual design. Refine your e-commerce site based on data-driven insights.
Advanced Page Rules Take advantage of Cloudflare's Page Rules feature. Use it to customize how your CDN handles requests and responses. Set up URL redirects. Configure cache bypass rules for specific URLs. Use custom security rules to protect your Magento store from vulnerabilities.
