# Avoid Landing Page Redirects

> [!CAUTION]
> **Deprecated** . This page was written for version 4 of the PageSpeed Insights API, which is deprecated and will be shut down in May 2019. [Version 5](https://developers.google.com/speed/docs/insights/v5/get-started) is the latest and provides both real-world data from the Chrome User Experience Report and lab data from Lighthouse.

This rule triggers when PageSpeed Insights detects that you have more than one redirect
from the given url to the final landing page.

### Overview

Redirects trigger an additional HTTP request-response cycle and delay page rendering. In the best
case, each redirect will add a single roundtrip (HTTP request-response), and in the worst it may
result in multiple additional roundtrips to perform the DNS lookup, TCP handshake, and TLS
negotiation in addition to the additional HTTP request-response cycle. As a result, you should
minimize use of redirects to improve site performance.

Here are some examples of redirect patterns:

- example.com uses responsive web design, no redirects are needed - fast and optimal!
- example.com → m.example.com/home - multi-roundtrip penalty for mobile users.
- example.com → www.example.com → m.example.com - very slow mobile experience.

### Recommendations

Learn the [fundamentals of responsive design](https://developers.google.com/web/fundamentals/layouts) to deliver a
great multi-device experience and eliminate unnecessary redirects.

If your site requires redirects, please see our [Redirects and User-Agent Detection](https://developers.google.com/webmasters/smartphone-sites/redirects) guidelines.
