Faster page loading speeds directly impact user experience and business metrics like conversion rates and revenue. According to studies, a half-second delay can cause a 20% reduction in traffic and a 100-millisecond increase caused a 1% rise in Amazon's revenue. Many tools exist to test page speed and identify optimization opportunities, such as reducing files, images, and HTTP requests as well as leveraging caching, CDNs, and database cleanup. Proper hosting, themes, plugins, and coding practices can help sites load faster.
