Case Study: Speed Kit achieves faster page loads and higher conversions with Fastly

Fastly helps Speed Kit reduce LCP in high-traffic websites by 0.5 seconds — boosting conversion rates by 5-10%

Speed Kit, the all-in-one page speed tool for high-traffic websites, needed a powerful CDN partner to support complex edge processing, fast cache invalidation, and global delivery without adding infrastructure changes. As it expanded into a broader performance platform, Speed Kit turned to Fastly and its CDN, WAF, and edge capabilities to help deliver better UX, SEO, and conversion performance.

Fastly implemented the CDN foundation that Speed Kit needed, along with Fastly Next-Gen WAF and Fastly Compute for advanced edge use cases. The results were strong: Speed Kit reports a 98% cache hit rate for typical customers, a 0.5-second reduction in LCP, 1-2% higher conversion rates for every 100 milliseconds of LCP improvement, and up to 80% less data transferred through custom compression dictionaries.
