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.
Reason why redirects are used?
- To direct the user to the new location of a resource.
- 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 browser.
The reason to apply redirects may be crucial from your point of view but it It is imperative to reduce the number of redirects especially for resources that are needed to start your homepage. You should avoid it in every possible case except when it is technically unavoidable.
How redirects affect the page load speed?
Redirects adds round-trip-time latency and triggers additional HTTP requests and consequently causes 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. Web browser is able to handle these types of redirects quickly than the client-side redirects.
Client-Side Redirects (Slow & Non-Cacheable)

It is important to ensure that all resources are being called in a manner that they do not create a redirect. This means that if your site is using "www", ensure that you are calling CSS, JS and other files using "www"
