Avoid multiple page redirects Redirects introduce additional delays before the page can be loaded. [Learn more](https://web.dev/redirects/). 100 Potential savings of 190 ms
Properly size images Serve images that are appropriately-sized to save cellular data and improve load time. [Learn more](https://web.dev/uses-responsive-images/). 100  
Cumulative Layout Shift Cumulative Layout Shift measures the movement of visible elements within the viewport. [Learn more](https://web.dev/cls/). 87 0.112

Avoid serving legacy JavaScript to modern browsers Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers. [Learn More](https://philipwalton.com/articles/deploying-es2015-code-in-production-today/) 100

Speed Index Speed Index shows how quickly the contents of a page are visibly populated. [Learn more](https://web.dev/speed-index/). 95 1.1 s
Avoids an excessive DOM size A large DOM will increase memory usage, cause longer [style calculations](https://developers.google.com/web/fundamentals/performance/rendering/reduce-the-scope-and-complexity-of-style-calculations), and produce costly [layout reflows](https://developers.google.com/speed/articles/reflow).

What is the use of Page Speed Insights?
PageSpeed Insights (PSI) reports on the performance of a page on both mobile and desktop devices, and provides suggestions on how that page may be improved. PSI provides both lab and field data about a page. Lab data is useful for debugging performance issues, as it is collected in a controlled environment.

PageSpeed Insights (PSI) reports on the performance of a page on both mobile and desktop devices, and provides suggestions on how that page may be improved.

PSI provides both lab and field data about a page. Lab data is useful for debugging performance issues, as it is collected in a controlled environment. However, it may not capture real-world bottlenecks. Field data is useful for capturing true, real-world user experience - but has a more limited set of metrics.
