// Performance
The sequence of steps a browser takes to convert HTML, CSS, and JavaScript into pixels on screen. Optimizing it means minimizing render-blocking resources, reducing DOM depth, and deferring non-critical scripts to reach First Contentful Paint faster.
Why it matters: Critical Rendering Path is one of the performance signals that shapes how search engines, AI tools, and real visitors experience your website. Getting it right removes friction, protects your rankings, and makes every other optimization work harder. Auditing it regularly is the fastest way to catch regressions before they cost you traffic or conversions.
