This rule is triggered when PageSpeed Insights detects that you used multiple redirects during the transition of the specified URL to the final destination page.

Because redirects trigger additional HTTP request response cycles and add additional round-trip time latency, it is critical to minimize the number of redirects issued by the application. Avoiding HTTP redirection can reduce the time users wait for Web pages to load. We suggest that you carefully consider the design of your website to see where you can improve the performance of your website.
