How TheSiteFuse checks "Render-blocking resources"
When a browser loads a page and encounters a script without "async" or "defer", it stops and waits for that file to download before continuing. It's like blocking the entire checkout queue.
Why it matters
Real-world impact of "Render-blocking resources"
Render-blocking resources delay page display, harming Core Web Vitals (LCP, FCP). Adding "defer" or "async" to scripts can reduce display time by several seconds.
