A redirect is a way for your website to send a quick message to your reader’s browser and tell them that the page they want to visit has been moved, so their browser can automatically point them to the new page of your choice.
The simplest way to add and manage redirects in WordPress is by using the Redirection plugin. Install and activate the plugin. Once activated, visit Tools » Redirection to setup your redirects.
Locate your page and hover your cursor over the title, then click Edit. You will then be presented with the ability to enter the redirect URL.
