301 Redirect for SEO : Comprehensive SEO Guide

Last year when I moved to a new place, I forgot to transfer my utilities. I was so focused on packing my belongings, I completely forgot about them. After I relocated, I found that my phone was dead, lights were out, and there was no gas in the kitchen.

What a disaster!

Undeniably, it was one of the most nerve-racking things I’ve experienced. It took a week to sort it out and have them up and running at my new place.

The same applies to your website too.

301 redirect is the term given for it in the world of technology.

If you’re moving your website’s URL, you have to make prior preparations so that when a user visits your site, they don’t find it to be dark and useless. A 301 redirect is a useful tool for maintaining the health of your website if not implemented in the right way it may affect the SEO services that you have already implemented to your website.

What is a 301 redirect?

By giving a 301 redirect command, you are sending details to search engines that you have permanently moved to a new URL. You’re requesting search engines to remove your old URL from their index and asking them to give credits to your new URL.

For example, if you want to redirect https://colorwhistle.com/cool/ to https://colorwhistle.com/, you have to give a 301 redirect to change from the old URL to the new URL. Once the redirect is in action, if someone wants to access https://colorwhistle.com/cool/ they would land on https://colorwhistle.com/.

To have a better understanding, let me explain how a web page is presented to a user. Whenever your website server provides a page of your site to a visitor, it gives a server status code in the header. This information is given even before the actual content is shown. It is to inform your web browser or search engine the contents (image, PDF, video) of the page.

ColorWhistle did a 301 redirect some time back. I have used it as an example to show what our server displayed when a user requested for the home page.
