Optimization Detective

Optimization Detective is a WordPress plugin that collects client-side performance metrics to inform server-side optimization decisions. It gathers real user monitoring data about which elements are visible in the viewport during page load. The plugin stores this data to make intelligent decisions about lazy-loading, preloading, and other optimization techniques. Optimization Detective helps eliminate render-blocking resources by identifying which content is truly above-the-fold for various devices and viewports. It works in conjunction with other WordPress performance plugins to improve Core Web Vitals scores. The plugin uses a data-driven approach rather than making assumptions about user behavior. Optimization Detective is particularly useful for responsive websites with varying content layouts across devices.
