What is a Redirect?
It is a method that is used to take the visitor from one URL to another URL. Redirecting can be done in several ways but each method affects the page loading speed.

- Tracking the clicks, and impressions and log referring pages.
- To retain multiple domains, and allow for "user-friendly" or "vanity" domains and URLs.
- To create a connection between the various country-code top-level domains, between different parts of a site or application, different security policies, different protocols.
- Adding trailing slash to URL directory names to make content accessible to the browser.

How redirects affect the page load speed?
Redirects add round-trip-time latency and trigger additional HTTP requests and consequently cause the pages to load slower. These are one single most time waster in the code.
Primarily mobile users are greatly affected by the number of redirects because they are not using a reliable network as compared to the desktop users.
Server-Side Redirects (Fast & Cachable)
There are two common redirects 301 (permanent) and 302 (temporary). These both server-side redirects that use HTTP in order to explain that a page and resource has moved. A web browser is able to handle these types of redirects quickly than the client-side redirects.
Client-Side Redirects (Slow & Non-Cacheable)
Redirects such as http-equiv="refresh" attribute or javascript can create performance issues and add longer waiting times. Therefore, these should be avoided in all the possible cases.
What type of redirects assist in SEO?
